  • A Comparison of Continuous and Interval Exercise on Cognition in Young

    • Authors: Emily C. Tagesen et al.
      Abstract: International Journal of Exercise Science 16(5): 458-468, 2023. Exercise stimulates the production and secretion of testosterone, cortisol, and brain-derived neurotrophic factor (BDNF) and affects cognitive performance. However, the interaction of these variables is unknown. To investigate these interactions, 21 college-aged men completed two work-matched exercise protocols: continuous (CONT) exercise and an interval protocol (INT). Blood and saliva samples were collected before and after exercise to quantify BDNF, cortisol, and testosterone. Participants completed a battery of cognitive assessments after exercise. A MANOVA analysis of condition demonstrated that no domains were significantly different after CONT and INT (p> 0.05). A repeated measures ANOVA of time by condition demonstrated increases in BDNF in after both CONT and INT (p = 0.05), elevated cortisol after CONT (p = 0.05), and an interaction of testosterone (p = 0.027). Work matched continuous and interval exercise appears to promote serum BDNF but do not result in different post exercise cognitive performance.

  • Blood Flow Restriction Attenuates Muscle Damage in Resistance Exercise
           Performed Until Concentric Muscle Failure.

    • Authors: Victor Magalhães Curty et al.
      Abstract: International Journal of Exercise Science 16(2): 469-481, 2023. The present study aimed to evaluate whether blood flow restriction (BFR) can prevent exercise-induced muscle damage in resistance exercise (RE) performed until concentric muscle failure (CMF). Twenty healthy volunteers (25 ± 4 years, 80.4 ± 11.8 kg, 175 ± 8 cm) performed three sets of unilateral biceps curl exercise (40% of 1RM) with (RE + BFR) and without (RE) BFR until CMF. A third condition was to perform the same number of repetitions as RE + BFR without using BFR (matched). Performing fewer repetitions, RE + BFR caused muscle fatigue post-exercise as high as that caused by RE. In addition, the range of motion, upper arm circumference, pressure pain threshold, and maximal voluntary contraction were immediately affected by our exercise protocol with BFR, returning rapidly to basal values within 24 h, while in RE, muscle damage markers remained elevated until 48 h post-exercise. The same results were observed concerning serum creatine kinase and lactate dehydrogenase activity. Thus, BFR + RE performed until CMF attenuated muscle damage following similar metabolic stress to RE alone performed until CMF, with less work volume.

  • IJES Self-Study on Participants’ Sex in Exercise Science: Sex-Data Gap
           and Corresponding Author Survey

    • Authors: Matthew J. Garver et al.
      Abstract: International Journal of Exercise Science 16(6): 364-376, 2023. A sex-data gap exists between females and males within the sport and exercise science literature, and implications are far-reaching. The purpose of this work was to (a) heed recent calls and scrutinize data from within IJES to address the gap and (b) gain insight on self-identified sex of IJES corresponding authors. The present self-study included all published manuscripts from 2008 through 2021. A total of 851 publications were included, and 806 (94.7%) reported data on participant sex. There was a difference between publications that included only females (n = 132) versus only males (n = 215), and three publications reported data on sex according to non-binary identifications (0.4%). There was an overall difference between the number of female (n = 54,153; 35.9%) and male (n = 96,890; 64.1%) participants. To gain insight on self-identified sex of corresponding authors, we performed an IRB-approved research study. Among 761 unique corresponding authors, 168 individuals provided 157 usable responses—58 biological females (36.9%) and 99 biological males (63.1%). We fully support the prerogative of researchers to ethically conduct investigations and encourage open-mindedness and inclusion in future research. With data revealing an approximate one-third female (36%) and two-thirds male (64%) composition, and corresponding author feedback on self-identified sex being similar (36.9% and 63.1%, respectively), we propose a new concept that should be analyzed: is the sex-data gap representative of the composition of the field' We are not excusing the sex-data gap issue as if it cannot be addressed, and we urge others to join us in researching this line of inquiry.

  • Directing attention externally produces consistent vertical jump
           assessment results

    • Authors: Logan T. Markwell et al.
      Abstract: International Journal of Exercise Science 16(5): 448-457, 2023. Recent research has demonstrated that consistent external attentional focus instructions produce more reliable jumping measurements compared to non-consistent focus of attention instructions. While previous research has examined the effects of different external attentional focus instructions, less is known about different external focus of attention instruction effects during a vertical jump. Given that previous work has demonstrated that consistent external focus of attention instructions produced reliable jumping estimations, we hypothesized that using multiple methods to direct attention externally would produce consistent vertical jump results. Using a within-participant design, college aged students (n = 35) completed two vertical jumps on a VertecTM within five conditions. Each condition was provided different external directing instructions conditions (control; external-lower near, -upper near, -upper far, -unreachable far). Data were analyzed using a repeated measures analysis of variance (ANOVA). Results showed that jump heights in the control and external focus of attention conditions were not significantly different from one another, p = .119. The findings of this study suggest there are numerous external focus of attention instructions that can be provided during a vertical jump producing consistent results.

  • Reliability of a Novel Automated Ultrasound Technology for Body
           Composition Assessment and Comparisons with Dual Energy X-Ray

    • Authors: Adam Bradley et al.
      Abstract: International Journal of Exercise Science 16(4): 393-401, 2023. Body composition tools vary in reliability, portability, and accessibility. The purpose of this study was to evaluate test-retest reliability of MuscleSound® (MS) and dual-energy x-ray absorptiometry (DXA) for both two compartment (region) and three compartment (tissue) models. A secondary aim was to compare body composition values produced by both devices. Fifty participants (n = 25 male, n = 25 female) aged 18-39 years completed two body composition assessments, twice in a single session. Participants arrived at the lab after a 12-hour fast. DXA required participants to lay supine for 10-15 minutes during the scanning process. Thereafter, MS was utilized to measure subcutaneous adipose tissue thickness at seven sites: chest, subscapula, triceps, axilla, suprailium, abdomen, and mid-thigh. MS automatically estimated body composition utilizing a modified Jackson-Pollock equation and the Siri equation within the software. The sequence of assessments was then repeated. Statistical analysis included paired T-tests with Pearson correlations, intraclass correlation coefficients (ICC), and least significant change (LSC). Both methods were strongly reliable (ICCMS = .997, ICCDXA-region = .999, ICCDXA-tissue = .999). MS and DXA-region body fat percentages were significantly different (mean difference (%): 2.60 ± 1.32, p < .001) but highly correlated (r = .928, p < .001). Notably, the mean difference was within DXA-region’s calculated least significant change of 3.24%. MS is reliable for assessing body fat percentage in young and middle-aged adults and operators can utilize MS to collect body composition data in the field.

  • Effects of Different Percentages of Blood Flow Restriction on Muscle
           Oxygen Saturation While Walking

    • Authors: Clayton Shriver et al.
      Abstract: International Journal of Exercise Science 16(2): 411-428, 2023. The purpose of this investigation was to determine the effect of different relative pressures of blood flow restriction (BFR) on muscle oxygen saturation (SmO2) while walking at 3.0 mph (4.83 kph). Fifteen physically active healthy adults performed seven 5-minute stages of walking at 3.0 mph with a blood flow restriction cuff applied to the proximal portion of the left or right leg while bilateral SmO2 changes were measured using near infra-red spectroscopy (NIRS) on the medial head of the gastrocnemius (GM) and vastus lateralis (VL) muscles. Other measurements including heart rate (HR), blood pressure (BP), rating of perceived exertion (RPE), and ground contact time balance (GCTB) were also collected. SmO2 measurements were analyzed using two-way repeated measures (RM) ANOVA while other measurements were analyzed using one-way RM ANOVA. We observed a significant main effect of LOP% (limb occlusion pressure) on the difference in total area of desaturation that occurred during each occlusion stage (ADS), p < 0.0001 η2 = .336, early ΔSmO2, p < 0.0001 in both the GAS η2 = .132 and VL η2 = .335. The results suggest that there are significant differences in SmO2 desaturation between 40%, 80%, and 100% LOP. Our findings suggest that incremental increases in LOP will bring about greater SmO2 desaturation during walking and may therefore induce a larger adaptive response on the muscles. However, increased LOP% may intensify perception of effort.

  • Arch Stiffness Does Not Determine Running Economy in Recreational Runners

    • Authors: Ian Bradford et al.
      Abstract: International Journal of Exercise Science 16(2): 402-410, 2023. The primary purpose of this study was to determine the relationship between foot length, arch stiffness, and running economy in recreational runner at low running velocities. Sixteen trained endurance (age 20.5 ± 0.4 yrs, height 172 ± 1.8 cm, and mass 68.53 ± 2.40 kg) athletes had their foot anthropometrics and running economy measured. Foot anthropometrics including Foot Length (FL), Arch Stiffness Index (ASI), and Achilles Tendon Moment Arm Length (ATML) were assessed. Subjects then completed a maximal oxygen consumption (VO2max) test and running economy (RE) assessment. RE was measured as the oxygen consumption during running at velocities of 9.9 km/h and 11.9 km/h at a 1% grade. Data is reported as Mean ± SE, and the relationship between foot anthropometrics and running economy was assessed with linear regression (α = 0.05). Results: Absolute and relative VO2max values were 3.68 ± 0.19 L/min and 52.96 ± 1.51 mL/kg/min. ASI was 1513 ± 174.27 A.U. with a standing foot length of 25.41 ± 0.4 cm. Subject oxygen consumption at 9.9 km/h and 11.9 km/h was 34.9 ± 0.80 mL/kg/min and 41.02 ± 0.82 mL/kg/min, respectively. There was no correlation between ASI, FL, AHI, and RE (p> 0.05). Arch stiffness and Achilles tendon moment arm do not determine running economy. Therefore, running economy may be impacted by other physiological and biomechanical factors at low running velocities

  • Training status impacts metabolic response to a high-protein weight loss
           diet in recreationally resistance-trained females.

    • Authors: Alyssa A. Olenick et al.
      Abstract: International Journal of Exercise Science 16(2): 377-392, 2023. This study investigated the effects of a novel high-protein diet template on postprandial metabolism and body composition (e.g., waist and hip circumference, body fat (%), fat mass, fat-free mass) in recreationally resistance-trained females. Fifteen females adhered to an eight-week high-protein dietary intervention (~1.5-1.6 g·kg-1·day-1) administered via template format. Pre- and post-intervention visits included anthropometrics, measurement of body composition, and an acute high-fat meal challenge. The high-fat meal challenge (61% fat) consisted of fasting postprandial blood glucose, resting metabolic rate (RMR), fat and carbohydrate oxidation assessed at 60-, 120-, and 180-minutes. Participants were split into high (HTF; 5-6 days ·week-1 of resistance training; n = 8) and low-training frequency (LTF; 2-3 days ·week-1 of resistance training; n = 7) groups. All metabolism data were assessed as absolute (kcal or g) and relative (kcal or g·kg·FFM-1·minutes-1) to fat-free mass. Post-intervention, there was a significant reduction in HTF waist circumference (p = 0.044), LTF body fat % (p = 0.012), and LTF fat mass (p = 0.014). Post-intervention, HTF females had significantly lower absolute RMR area under the curve (AUC) than LTF females (p = 0.036). LTF females had higher absolute fat oxidation AUC compared to HTF females’ pre-intervention (p = 0.048) but a significant decrease in absolute (p = 0.050) and relative (p = 0.050) fat oxidation AUC post-intervention. LTF females had a significant increase in absolute (p = 0.032) and relative (p = 0.029) carbohydrate oxidation AUC pre- to post-intervention (p = 0.032). For blood glucose, no significant differences between groups were detected (p> 0.05). These findings suggest that a novel high-protein diet template elicits a metabolic shift favoring carbohydrate oxidation in females engaging in low-frequency resistance training but did not alter fat and carbohydrate metabolism in females engaging in HTF resistance training.

  • Anthropometric Predictors of Conventional Deadlift Kinematics and
           Kinetics: A Preliminary Study

    • Authors: Dale S. Keith et al.
      Abstract: International Journal of Exercise Science 16(1): 429-447, 2023. The purpose of this preliminary analysis was to determine if there are relationships between anthropometric characteristics (arm length, torso length, thigh length, and shank length) and conventional deadlift (CDL) kinematics and kinetics during a 5 sets of 5 repetitions (5 x 5) CDL routine in resistance-trained males. Eleven males who had experience with the deadlift exercise were included in this analysis (age: 21.5 ± 1.4 y; height: 180.7 ± 5.7 cm; body mass: 89.9 ± 16.0 kg). Anthropometrics were measured by a 3-dimensional optical scanner. The participants underwent a 5 x 5 CDL workout using a self-selected load corresponding to a rating of perceived exertion (RPE) of 8 out of 10. Performance outcomes were measured synchronously using a 3-dimensional 12-camera motion capture system and two force platforms. Outcomes were averaged across all sets and analyzed using multiple linear regression. The selected anthropometric variables were not significantly related to the CDL performance outcomes, except for concentric ankle work. However, in the overall model, anthropometric predictors did not significantly predict ankle concentric work (p = 0.11; R² = 0.67; R²adj = 0.45). Independently, thigh length significantly correlated with ankle concentric work (p = 0.03). In this model, thigh length accounted for 55% of the normalized variance in ankle concentric work. The results from this preliminary study suggest that arm length, torso length, and shank length may not play a clear role in the examined CDL outcomes, but thigh length may be positively correlated with ankle concentric work during a 5 x 5 CDL routine in resistance-trained males.

  • Estimates of agreement between three low-cost and one high-cost
           bioelectrical impedance analyzers using classical and contemporary

    • Authors: ROBERTO GONZÁLEZ MARENCO et al.
      Abstract: International Journal of Exercise Science 16(4): 353-363, 2023. The aim of this study was to determine the concordance between the estimates of three low-cost and one high-cost electrical bioimpedance equipment (BIA) in classical and contemporary dancers. Participation in the study included 28 subjects (15 men and 13 women) 18 to 35 years old, who perform classical and/or modern dance, thrice weekly, from 60 to 120 min per session, for 10 years or more. Those who presented any disease, consumed drugs, supplements or multivitamins; had prostheses, surgical metal parts or pacemakers, had problems maintaining the correct anatomical positions for taking measurements, and pregnant women were excluded. Their body composition was determined with 3 low- cost BIA equipment (OMRON HBF-306C, SKULPT CHISEL and BEURER BF 1000) and one high-cost equipment (SECA mBCA 515). The results indicated that in men, SKULTP in its “complete” modality had the highest agreement with SECA (CCC=0.73, 95% CI=0.46-0.88) for body fat percentage (%BF); in women, OMRON in its “normal” modality had the highest agreement with SECA (CCC=0.85, 95% CI=0.62-0.94) for %BF; while BEURER had poor concordances (CCC=0.86-0.03) for the rest of the estimates in its different modalities, in both sexes. It is concluded that the lower cost equipment (SKULPT and OMRON) were the most consistent with SECA for %BF in normal weight dancers. BEURER had the lowest agreements with SECA, in all its modalities, as well as inconsistent estimates for all parameters. Therefore, there was no relationship between the cost of the low-cost impedance equipment and its agreement with those of a high-cost one.

  • Changes in Physical Activity During the COVID-19 Pandemic: A Mixed Methods

    • Authors: Andrew Corbett et al.
      Abstract: International Journal of Exercise Science 16(5): 327-341, 2023. COVID-19 was declared a global pandemic in March 2020. Resulting containment protocols altered the day-to-day lives of people around the globe, impacting typical physical activity patterns. The purpose of this mixed-method study was to understand how physical activity changes occurred during the first few months of the COVID-19 pandemic. Participants (n = 271) completed a survey including a qualitative item asking for descriptions of how their physical activity had changed, as well as a categorical item asking whether they had become more active, stayed equally as active, or become less active during the pandemic. Qualitative responses were analyzed to identify emergent themes, and chi-squared analyses were used to compare proportional differences in themes according to self-reported physical activity classification. Analysis revealed 10 themes: (1) decreased transportation-related physical activity, (2) change in location, (3) loss of resources, (4) discrepancies between self-reported changes in activity level and description of activities, (5) increased transportation-related physical activity, (6) changes in routines, (7) adapting exercise, (8) avoiding contact, (9) changes unrelated to COVID-19, and (10) illness or injury. Significant differences existed between groups for all themes except for avoiding contact, changes unrelated to COVID-19, and injury or illness. Empowering individuals to overcome barriers may be important during a pandemic to help people maintain or increase physical activity levels. Future research should explore the continued experience of people during the COVID-19 pandemic and investigate its impact on levels of physical activity going forward.

  • The Effect of a Division 1 Women’s Basketball Strength and Conditioning
           Protocol on Mental Toughness

    • Authors: Zach Olivan et al.
      Abstract: International Journal of Exercise Science 16(5): 315-326, 2023. Mental toughness (MT) is a popularized term in sports since it has been found to be positively related to performance. Self-assessment is the most common method of MT data collection. In the strength and conditioning (S&C) context, MT research has focused on males with a notable lack of female participants. Division 1 NCAA strength and conditioning coaches (SCC) spend more hours with their athletes during offseason training than any other coach. The purpose of this study was to measure the perceived effectiveness of an off-season S&C training regimen on MT levels of female athletes while also examining the differences in these perceptions between athletes, teammates, and their SCC. Following a quasi-experimental, longitudinal design, 12 student-athletes assessed their own (n = 58) and one teammate’s (n = 58) levels of MT using the Mental Toughness Index five times over their off-season training S&C regimen. The SCC rated his players, as well (n = 60). MT levels increased significantly post-intervention [F (1, 23) = 7.27, p = .001]. The student-athletes perceived the effect of the intervention as more substantial compared to the SCC [F (1, 117) = 49.03, p

  • Heart Rate Variability as a Neuroautonomic Marker to Assess the Impact of
           Karate Training – An Observational Pediatric Study

    • Authors: Puneet Bhattacharya Ms et al.
      Abstract: International Journal of Exercise Science 16(2): 342-352, 2023. Habitual physical activity improves heart functions and parasympathetic tone; Karate training is considered as a moderate physical activity with rhythmical breathing patternology. Heart rate variability (HRV) is an electrophysiological tool which measures cardio autonomic homeostasis; is used in the present study as an indirect marker to measure neurocognitive development with karate training. The aim of the present study was to find out the impact of regular karate training on cardiac autonomic responses through Heart Rate Variability (HRV) between karate players and age-sex matched active controls. A total of 30 male school-going children were evaluated; fifteen were experienced male karate practitioners (9.5±1.26 years) and fifteen controls (10.6±1.57 years). The time and frequency domain measures of HRV were taken into account after check for normality distribution, followed by t-test for comparison of Mean±SD. Frequency domain measures; low frequency normalized unit (LF nu) and low frequency is to high frequency ratio (LF/HF ratio) both showed significant reduction in the karate group which quantified sympathetic disposition while High frequency normalized units (HF nu) reflected a significant rise and it predicted increase in parasympathetic tone. Karate practitioners show higher HRV measures and more involvement of the parasympathetic nervous system which help in stress resilience and improved recovery time. This training if performed regularly from an early age can improve cardiac health which is very pertinent in the present times.

  • Comparable Acute Metabolic Responses when Walking with Blood Flow
           Restriction and Walking with Load Carriage: Implication for Tactical

    • Authors: Nathan D. Dicks et al.
      Abstract: International Journal of Exercise Science 16(2): 304-314, 2023. The current study aimed to investigate exercise with blood flow restriction (BFR) as a low-intensity conditioning strategy in tactical professionals with load carriage. During the low-intensity exercise, researchers examined the acute metabolic responses from low-intensity BFR walking, walking with load carriage, and walking with BFR and load carriage. Twelve healthy adult males (age = 21.8 ± 1.5 yrs, height = 181.3 ± 7.2 cm, body mass = 84.4 ± 11.1 kg and BMI = 25.6 ± 2.6 kg.m2) completed five bouts of 3-min treadmill walking at 4.8 kmh-1 with 1-min rest interval under three different conditions: 1) blood flow restriction (BFR), 2) loaded with 15% of body mass (LOAD) and 3) loaded with 15% of body mass with blood flow restriction (BFR-LOAD). Oxygen consumption (O2), heart rate, and local muscle oxygen saturation was measured during the exercise bouts. O2 increased by 7% during the BFR- LOAD (p = 0.001) compared with BFR or LOAD alone. There were no differences in O2 between BFR and LOAD (p = 0.202). BFR-LOAD showed significantly lower (-9%) muscle oxygen saturation (p = 0.044) and deoxygenated hemoglobin (p = 0.047) compared to LOAD. Low-intensity walking with the addition of BFR shares acute metabolic characteristics similar to walking with a load. These characteristics suggest there is potential for the use of BFR to increase exercise intensity for individuals training with load carriage.

  • The heart rates and movement speed of Specialist Tactical Police during a
           multistorey active shooter training scenario

    • Authors: Jeremy Robinson et al.
      Abstract: International Journal of Exercise Science 16(4): 281-292, 2023. Specialist police tactical groups (PTGs) are involved in situations that extend beyond the capability of general duties police and can include responding to active shooter incidents. Due to the nature of their tasks, these officers typically carry and wear additional equipment which can impart an increased physical cost, for which the officers must be prepared. The aim of this study was to examine the heart rate responses and movement speeds of specialist PTG officers during a multistorey active shooter scenario. Eight PTG officers completed an active shooter scenario within a multistorey office building district whereby they were required to carry and wear their usual occupational personal protection equipment (average load = 16.25 ± 1.39 kg) while clearing high-risk environments and locating an active threat. Heart rates (HR) and movement speeds were all recorded via HR and global positioning system monitors. Average PTG officer HR over the duration (19.14 ± 0.70 minutes) was 165 ± 6.93 bpm (89 ± 4% age predicted heart rate maximum (APHRmax)) with 50% of the scenario performed at intensities between 90-100% APHRmax. Around 75% of the scenario had the officers moving at speeds of between 3-6.99 kilometers per hour (km/h), although speeds of 7-10.99 km/h were not uncommon. Understanding the responses of specialist officers during a multistory active shooter scenario may help in designing specific strength and conditioning programs to meet this potential scenario demand.

  • Neuromuscular Responses to Failure vs Non-Failure During Blood Flow
           Restriction Training in Untrained Females

    • Authors: Christopher E. Proppe et al.
      Abstract: International Journal of Exercise Science 16(1): 293-303, 2023. Applying blood flow restriction (BFR) during resistance exercise is a potent stimulus of muscular adaption, but there is little direct comparison of its effect on neuromuscular function. The purpose of this investigation was to compare surface electromyography amplitude and frequency responses during a 75 (1 × 30, 3 × 15) repetition bout (BFR-75) of BFR to 4 sets to failure (BFR-F). Twelve women (mean ± SD age = 22 ± 4 years; body mass = 72 ± 14.4 kg; height = 162.1 ± 4.0 cm) volunteered for the investigation. One leg was randomly assigned to complete BFR-75 and the other to BFR-F. Each leg performed isokinetic, unilateral, concentric-eccentric, leg extension at 30% of maximal strength while surface electromyographic (sEMG) data was recorded. More repetitions (p = 0.006) were completed during set 2 for BFR-F (21.2 ± 7.4) than BFR-75 (14.7 ± 1.2), but there were no other between condition differences for set 1 (29.8 ± 0.9 vs 28.9 ± 10.1), set 3 (14.4 ± 1.4 vs 17.1 ± 6.9), or set 4 (14.8 ± 0.9 vs 16.3 ± 7.0). Collapsed across condition, normalized sEMG amplitude increased (p = 0.014, 132.66 ± 14.03% to 208.21 ± 24.82%) across the first three sets of exercise then plateaued, while normalized sEMG frequency decreased (p = 0.342, 103.07 ± 3.89% to 83.73 ± 4.47%) across the first two sets then plateaued. The present findings indicated that BFR-75 and BFR-F elicited similar acute neuromuscular fatigue responses. The plateau in amplitude and frequency suggested that maximal motor unit excitation and metabolic buildup may be maximized after two to three sets of BFR-75 and BFR-F.

  • Salivary Cortisol Analysis in Collegiate Female Lacrosse Athletes

    • Authors: Jenna L. Carter et al.
      Abstract: International Journal of Exercise Science 16(6): 242-251, 2023. Cortisol is a hormone that corresponds to physiological and emotional stress. The purpose of this study was to 1) evaluate the changes in cortisol in female Division I collegiate lacrosse players (n = 15) throughout the competitive season, and 2) evaluate the correlation between cortisol and athlete wellness and workload. Salivary cortisol samples were collected weekly in the morning throughout the entirety of the 2021 competitive season (12 weeks). Subjective athlete total wellness scores and sub-scores (muscle soreness, sleep quality, fatigue, and stress) were taken on the same days. Objective total weekly Athlete Load (AL, an amalgam workload metric) were tabulated from the previous training week. A significant effect of time was found on wellness (p < 0.001) and AL (p < 0.001) over the twelve weeks with weekly differences, such as weeks with more than one game, weeks with no games, weeks with students in quarantine (not competing), or weeks with academic stressors such as final exams. There were no weekly differences in cortisol (p = 0.058). Cortisol had negligible correlations with wellness (r = -0.010, p = 0.889) and AL (r = 0.083, p = 0.272) during the competitive season. These findings suggest that cortisol changed little for athletes throughout the season although training volume and wellness did. Thus, assessing acute responses of cortisol may prove to be more beneficial to evaluating athletes’ stress.

  • The effects of carbohydrate intake on body composition and muscular
           strength in trained men undergoing a progressive resistance training

    • Authors: Alex Silva Ribeiro et al.
      Abstract: International Journal of Exercise Science 16(2): 267-280, 2023. This study's purpose was to compare the effects of different carbohydrate (CHO) intakes on body composition and muscular strength following eight weeks of resistance training (RT) in pre-conditioned men. In addition, we explored the individual responses to different CHO intakes. Twenty-nine young men volunteered to participate in this study. The participants were divided into two groups according to their relative CHO intake: lower (L-CHO; n = 14) and higher (H-CHO; n = 15). Participants performed a RT program four days a week for eight weeks. The lean soft tissue (LST) and fat mass were determined by dual-energy X-ray absorptiometry. Muscular strength was determined by a one-repetition maximum (1RM) test in the bench press, squat, and arm curl exercises. Both groups increased LST (P < 0.05) with no statistical differences between conditions (L-CHO = +0.8% vs. H-CHO = +3.5%). Neither group demonstrated changes in fat mass. Both groups increased 1RM (P < 0.05) in the bench press (L-CHO = +3.6% vs. H-CHO = +5.8%) and squat (L-CHO = +7.5% vs. H-CHO = +9.4%); however, only H-CHO significantly increased arm curl 1RM (P < 0.05) at post-training (L-CHO = +3.0% vs. H-CHO = +6.6%). Responsiveness was greater in H-CHO vs. L-CHO for LST and arm curl 1RM. In conclusion, lower and higher CHO intakes promote similar increase in LST and muscular strength; however, a greater intake may improve the responsiveness to gains in lean mass and arm curl strength in pre-conditioned men.

  • Astaxanthin Reduces Heart Rate and Carbohydrate Oxidation Rates During
           Exercise in Overweight Individuals

    • Authors: Alissa Wika et al.
      Abstract: International Journal of Exercise Science 16(2): 252-266, 2023. Astaxanthin (AX) is an antioxidant which may spare endogenous carbohydrates and improve fat oxidation rates, thus improving metabolic flexibility. To date, no studies have attempted to examine the impact of AX in an overweight cohort, whom often suffer from metabolic inflexibility. Nineteen subjects (mean ± SD: age: 27.5 ± 6.3 years; height: 169.7 ± 9.0 cm; body mass: 96.4 ± 17.9 kg; BF%: 37.9 ± 7.0%; BMI: 33.4 ± 5.6 kg/m2; VO2peak: 25.9 ± 6.7 ml·kg−1·min−1) were recruited and supplemented with either 12 mg of AX or placebo (PLA) for 4 weeks. Subjects completed a graded exercise test on a cycling ergometer to examine changes in substrate oxidation rates. A total of 5 stages, each lasting 5 min and resistance increased 15 W each stage, were completed to examine changes in levels of glucose and lactate, fat and carbohydrate (CHO) oxidation rates, heart rate, and rating of perceived exertion (RPE). Although there were no changes found in rates of fat oxidation, blood lactate or glucose, or RPE (all p > 0.05), a significant decrease was observed in CHO oxidation from pre to post supplementation in the AX group only. Further, the AX group demonstrated a 7% decrease in heart rate across the graded exercise test. These findings suggest that 4 weeks of AX supplementation may offer some cardiometabolic benefits to overweight individuals, and be a favorable supplement for these individuals beginning an exercise program.

  • The metabolic and physiological demands of a simulated fire ground test
           versus a live-fire training evolution in professional firefighters

    • Authors: Drew Edward Gonzalez et al.
      Abstract: International Journal of Exercise Science 16(7): 230-241, 2023. Objective: This study examined the similarities in metabolic and physiological demands of a fire ground test (FGT) and a live fire training evolution. Methods: Twenty-seven firefighters completed either a FGT (n = 13) or a live fire training evolution (n = 14). Salivary samples were collected pre, immediately post, and 30-minutes post FGT and live fire training evolution, and analyzed for cortisol, uric acid, and interleukin-1β (IL-1β). Heart rate (HR) was measured pre- and post-task. Results: Both tasks resulted in significant elevations in cortisol, IL-1β, and HR. Conclusions: Both the FGT and live fire training evolution appear to result in similar metabolic and physiological demands. Further work may expand upon the additional elements (i.e., added heat) of the live fire training evolution. Fire departments may consider incorporating a variety of high intensity training to prepare personnel for these occupational demands.
