  • Sex-related differences in the sagittal plane spinal angles in preschool
           and school-age children

    • Abstract: Study aim: The study aimed to assess the differences in the magnitude of the anterior-posterior spinal curvatures depending on sex in children aged 5 and 9 years.Material and methods: This prospective longitudinal observational study included 67 children (29 girls and 38 boys) in pre-school-age and school-age phases (the first examination at 5 years old and the second examination at 9 years old). Measurements of body weight and height were recorded. The computerized assessment of body posture was performed with the photo-grammetric method (MORA 4 Generation). The normality of the distribution of variables was assessed with the Shapiro-Wilk test. The Mann-Whitney U test was used to analyze the differences between the sexes in terms of body posture parameters and somatic parameters.Results: There were no statistically significant sex-related differences in the values of parameters of the anterior-posterior spinal curvatures in 5-year-old children. In the group of 9-year-old children in the angle of lumbar lordosis, a significant difference between the sexes was found (U = 387.00, p < 0.05). Girls aged 9 had a significantly higher mean value of the angle of lumbar lordosis than boys at the same age (p < 0.05).Conclusions: A sex-related difference was found in the magnitude of lumbar lordosis in school-age children. Understanding the gender differentiation of lumbar lordosis is the first step towards explaining the wide variability of normal lumbar lordosis in adults and the developmental and biomechanical differences between male and female lumbar spines.

  • Analysis of Olympic and World boxing medalists from 1904 to 2019: The role
           of age, height, weight categories and nationality

    • Abstract: Study aim: To investigate the role of age, height, and weight categories on the performance of top nations and boxing medalists in Olympic Games (OG) (1904–2018) and World Championships (WG) (1974–2019).Material and methods: Data were collected from 1,806 athletes using the website of International Boxing Association (AIBA), International Olympic Committee (IOC) and Wikipedia.Results: The average age of medalists was ~24yrs with an increase of age (medium effect) across this 115 years period. Height was 1.76m and the super heavy category had significantly higher values by age and height compared to the other weight categories. The top medalists were three men with triple gold medals on OG and 13 over three on WC. Performance was associated with nationality (p < 0.01, medium effect), where a dominance of Cubans (211 medals) was observed.Conclusion: These findings highlighted the importance of the long-term development and specialization of talent athletes for peak performance in elite competitions.

  • Non randomised trial of GRAVITY system therapy effectiveness in chronic,
           low intensity low back disc disease

    • Abstract: Study aim: Chronic low back pain (CLBP) is a therapeutically challenging pain syndrome. Physical exercises are the most common therapy used in CLBP treatment. The aim of the study was to verify if GRAVITY system exercise can be effective in the therapy of chronic discogenic low back pain. The GRAVITY system exercise aims at strengthening full body muscles using the trainee’s own body weight only.Material and methods: The study was registered at ClinicalTrials.gov Identifier: NCT04765293. We used TREND statement. The study populations were 50 patients with CLBP. The study population (group I) consisted of 25 patients who had GRAVITY system exercise. The clinical control group were 25 patients who received standard treatment in an outpatient clinic of National Health Fund. Before the start of the training, the patients’ had their muscle strength responsible for stabilizing the lumbar segment measured. We also measured patients’ Oswestry Disability Index (ODI) prior to and after the therapy cycle. The therapy was conducted twice a week for 40 minutes over the period of 4 weeks. The clinical control group were 25 patients who received treatment from the National Health Fund and had only standardised physical therapy (laser, ultrasound, cryotherapy and magnetic therapy) sessions for two weeks.Results. We found statistically significant reduction in pain and disability in the study population after the treatment, but muscle strength did not increase significantly.Conclusions: 1. GRAVITY system exercise might efficient in pain and disability reduction. Muscle strength did not increase after therapy. 2. Pain and disability had positive correlation with female sex, decreased physical activity and sedentary work.

  • Does L. affect hormonal responses following high-intensity resistance
           exercise'

    • Abstract: Study aim: To investigate the effect of a 2-week supplementation with Tribulus terrestris L. (TT) on the responses of testosterone, cortisol, and thyroid hormones including triiodothyronine (T3) and thyroxine (T4) following an intensive session of resistance exercise (RE).Materials and methods: Twenty-two healthy non-athlete men (23.8 ± 3.1 years) participated in this study were divided into two groups and were randomly assigned to receive either TT supplementation (n = 11) or a placebo (n = 11). They consumed two 250-mg capsules with TT or placebo (maltodextrin) per day and performed six REs with the intensity 80-90% of 1RM on the fifteen day of the experiment. Venous blood samples were drawn before supplementation, and before and after the RE session.Results: The mean values of post-exercise testosterone and cortisol in both groups were significantly higher than pre-exercise and baseline (p < 0.01); however, there were no significant differences between the groups (p > 0.05). Likewise, despite a trend toward different levels of the responses of thyroid hormones with TT supplementation, there were no significant differences either in different time points or the groups (p > 0.05).Conclusions: Short-term supplementation with TT appears to be ineffective in changing the hormonal responses measured in this study following a session of high-intensity RE.

  • Influence of obesity on spatiotemporal gait parameters among female
           students from Jouf University, Saudi Arabia

    • Abstract: Study aim: The aim of the current study is to explore the effect of obesity on spatiotemporal parameters of gait in obese young female students.Material and methods: A cross-sectional study with fifteen obese female university students (mean age = 20.3 ± 1.6, mean BMI = 36.2 ± 4.6) and fifteen normal weight female university students (mean age = 20.9 ± 2, mean BMI = 22.6 ± 2.4) was conducted. The spatiotemporal gait parameters were evaluated using GAITRite® walkway (Frankline, USA, Model No. TR30RAM090 with software version 4.89C2).Results: Independent sample t-test showed statistical significant differences in some spatiotemporal gait parameters between normal and obese subjects with statistically significant reductions of single-limb support time, step length, stride length, and velocity in the obese subjects rather than normal subjects (p = 0.031, 0.015, 0.039, and 0.002, respectively). Moreover, there were statistically significant increases of step time, stride time in the obese subjects rather than the normal subjects (p = 0.038, 0.017, respectively).Conclusion: These results suggested that obesity is a factor that adversely affects the spatiotemporal gait parameters in the obese young female. This may be contributed to decrease the joints’ mobility and increase the incidence of joint osteoarthritis. So, it is recommended to encourage the sufficient physical activity and weight reduction among obese female students.

  • Effects of exercise training on depression and anxiety with changing
           neurotransmitters in methamphetamine long term abusers: A narrative review
           

    • Abstract: Study aim: It is generally accepted that methamphetamine (MA) is a highly addictive psychostimulant which copies functions of certain neurotransmitters in the brain, and emits dopamine and serotonin in the brain. Frequent abuse of methamphetamine damages dopaminergic and serotonergic nerve endings at different sites of brain and also increases the anxiety and depression. Exercise seems to reverse physiological and neurological damages due to previous MA dependents and help to reduce anxiety and depression in this population. The aim is to determine the effect of exercise training on neurotransmitters and rate of depression and anxiety in chronic methamphetamine abusers based on a literature review.Materials and methods: The present study investigated published articles in five computerized databases including Magiran, Google scholars, SID, PubMed and Scopus from 2011 until 2020. The searched keywords included sports, neurotransmitter, methamphetamine, depression, anxiety and treatment. The obtained results were described using texts, table and figure.Results: According to the results, physical activity and exercise significantly increased blood serotonin and dopamine levels and significantly decreased the depression and anxiety.Conclusion: Different evidences suggested that physical activity and exercise as positive responses and adaptations might influence on circulatory levels of two neurotransmitters (serotonin and dopamine) in methamphetamine addicts, decrease anxiety and depression, and improve preparation in previous MA dependents. In the rehabilitation period, the overall improvement in previous MA dependents might significantly increase. Exercise training can improve the physical and mental state of people addicted to methamphetamine as a non-drug therapy to promote health. However, more research is necessary to support this conclusion.

           perimenopausal diabetic women

    • Abstract: Study aim: To evaluate the effectiveness of extracorporeal shockwave therapy (ESWT) for frozen shoulder in perimenopausal diabetic women.Materials and methods: A single blind randomized controlled trial was conducted on sixty-two perimenopausal women diagnosed with diabetic frozen shoulder. They were divided randomly into two groups. Group (A) received physiotherapy program in the form of maitland joint mobilization for shoulder joint, self-stretching exercises, range of motion exercises (ROM) and strengthening exercises. Sessions were held 3 times per week, for 4 weeks. Group (B) study group: received the same physiotherapy program in addition to ESWT, once per week, for 4 weeks. Visual analogue scale was used to measure pain intensity, shoulder pain and disability index (SPADI) was used to evaluate disability level, while an electrogoniometer was used to measure shoulder flexion, abduction and external rotation range of motion. All measurements were recorded pretreatment and posttreatment program.Results: For intragroup comparison, significant improvement in all treatment outcomes was noted in both groups (P < 0.05). However, no significant differences were found between both groups regarding all outcome measures in case of intergroup comparison in the study (P > 0.05).Conclusion: The use of ESWT have a positive effect in reducing pain and improving shoulder range of motion in perimenopausal women suffering from frozen.

  • Effect of soft tissue manipulation of popliteus muscle on quadriceps
           

    • Abstract: Study aim: Popliteus is majorly associated with posterior knee pain; however, this muscle can also have an impact on anterior knee pain. The purpose of this study was to determine the effect of soft tissue manipulation of popliteus muscle on non-traumatic anterior knee pain in athletes; as the relationship between popliteus and Quadriceps muscle has not been studied/explored much.Materials and methods: In this experimental study, 15 subjects presenting with non-traumatic anterior knee pain were selected. Quadriceps muscle activity, torque production and knee pain were assessed. Followed by a single session of popliteus manipulation all the above parameters were re-assessed immediately and at 24 hours after intervention.Results: Significant reduction in pain (P < 0.005) at 24 hours was observed. There was a significant increase in muscle activity of Vastus Medialis (P < 0.05) and Vastus Lateralis (P < 0.005) immediately after the intervention but not after 24 hours. No significant change was found in the activity of Rectus femoris and Peak torque of Quadriceps immediately after the intervention and at 24 hours.Conclusion: Soft tissue manipulation decreased knee pain and improved muscle activity. Therefore, incorporating popliteus manipulation can be effective in treatment of anterior knee pain.

  • Effect of types of stimuli, handedness and gender differences on reaction
           time among adults students during the COVID-19 pandemic

    • Abstract: Study aim: The COVID-19 pandemic has unhinged the lives of people across the globe, in particular, university students who are home-schooling. No study has investigated the influence of specific parameters on reaction time (RT) among university students during the COVID-19 pandemic. The current study aims to describe the relationship between RT and parameters (types of stimuli, handedness, and gender differences) that may affect its values during the COVID-19 pandemic.Material and methods: RT of 60 volunteers to visual and auditory stimuli were recorded using the drop ruler method. RT was compared within-subject with respect to handedness and type of stimulus, and between subjects with regards to gender.Results: Although a small difference between RT reported as a function of hands and gender was observed, these results were statistically insignificant. However, females had a significant shorter RT to visual than the auditory stimulus.Conclusions: Findings showed that no significant differences were obtained between all comparisons made, except between females RT to visual stimulus and auditory stimulus. This can be attributed to the high level of stress and anxiety that may occur among students due to the COVID-19, which is the most prevalent and dangerous topic for university students, especially female students.

  • Motor memory consolidation in children: The role of awareness and sleep on
           offline general and sequence-specific learning

    • Abstract: Study aim: The purpose of this study was to investigate the role of sleep and awareness on consolidation of general and Sequence-Specific learning in children.Material and methods: Male participants (n = 48, 10 to 12 years old) were assigned to one of four groups based on awareness and sleep. Acquisition phase took place in the morning (wake groups, 8 ± am) or in the evening (sleep groups, 8 ± pm) followed by a 12 hours retention interval and a subsequent delayed retention test (1 week). Children in the explicit groups were informed about the presence of the sequence, while in the implicit groups were not informed about it. For data analysis in consolidation of general sequence learning and Sequence-Specific Consolidation phases, 2 × 2 × 2 and 2 × 2 × 3 ANOVA with repeated measures on block tests were used respectively.Results: The data provides evidence of offline enhancement of general motor learning after 12 hours which was dependent on sleep and awareness. Moreover, the information persistence after 1-week was significant only in sleep groups. The results also indicated that consolidation of sequence-specific learning was only observed after 12 hours in element duration and it was related to sleep and awareness.Conclusions: The results revealed that sleep wasn’t only an essential factor in enhancement of off-line sequence learning task after 12 hours in children, but performance of the children was dependent on awareness and sleep.

  • Comparison of ground reaction forces and joint kinematics between three
           different tempos during push-up exercise

    • Abstract: Study aimThis study was aimed to analysis in detail how different tempos [2:0:2 (30 bpm), 1:0:1 (60 bpm), Explosive (EXP)] effect to ground reaction forces (vGRF) and joint kinematics of push-up exercise (PUP).Material and methodsTwenty-four recreationally male athletes (age: 24.9 ± 3.6 years) participated in this study. Kinetic and kinematic data were obtained by load-cells and a motion analysis software. Data was analysed from a single repetition which is showed peak vGRF of dominant side during PUP. Joint velocities were calculated by taking the difference between the descent and ascent phases.ResultsThere was significant difference between 2:0:2 (30 bpm) – EXP in terms of dominant side of shoulder (p ≤ 0.02) and between 1:0:1 (60 bpm) – EXP in the dominant elbow joint displacements (p ≤ 0.05). The velocity differences between the descent and ascent phases of shoulder and elbow joints were found statistically significant between tempos (p ≤ 0.05). In terms of range of motion (ROM) of right and left side, there was significant differences between tempos (p ≤ 0.001). No significant differences were found between all tempos in the ascent phase of right-left and left descent phase in terms of average vGRF (p > 0.05) except right descent average vGRF (p ≤ 0.02).ConclusionsIn conclusion, right-left sides of ROM was used most effectively in 2:0:2 (30 bpm) and 1:0:1 (60 bpm) tempos. Less displacement was also observed in EXP and when tempo increased percentage of peak vGRF (at elbow flexion phase for right-left sides) to total repetition decreased. Highest ascent and descent phase velocity differences (for right-left sides) and highest peak vGRF (elbow flexion phase) observed in EXP. This study shows that increasing tempo will result in more unsteady joint kinematics and more vGRF, so if the goal is controlled and safe PUP, tempo should be slow.

  • Associations between differing magnitudes of inter-limb asymmetry and
           linear and change of direction speed performance in male youth soccer
           players

    • Abstract: Study aim: This study examines the relationship between different magnitudes of asymmetry and their effects on speed performance.Material and methods: Forty-two sub-elite male youth soccer players performed a 30-m sprint, change of direction, single leg countermovement jump and single leg hop. Subjects were divided into groups with vertical and horizontal asymmetry, and both groups were then divided into three groups according to magnitudes of inter-limb asymmetry (<5%, 5–10%, and >10%).Results: The results showed no significant correlation between different jump asymmetry magnitudes and the mentioned outcomes of speed performance (p > 0.05). In addition, larger asymmetries resulted in faster linear speed, even if small differences (g range = 0.00 to 0.57; p > 0.05). But this was not similar for change of direction speed (g range = –0.42 to 0.34; p > 0.05).Conclusions: There are inconsistent findings for the effects of inter-limb asymmetries on speed performance. The results of the present study indicate that the magnitude of asymmetry had no meaningful association with independent measures of performance in soccer players. Therefore, it seems more likely to explain the effects of individual asymmetries on performance rather than the idea that asymmetry negatively affects performance.

  • Are swimming coaches ready to help injured young swimmers'

    • Abstract: Study aim: This study aimed to determine the knowledge and skills of swimming coaches in providing first aid and cardiopulmonary resuscitation (CPR).Material and methods: The sample consisted of 59 swimming coaches who responded to non-standardized questionnaire. The collected data were processed by the statistical program IBM SPSS (20.0), using the Chi-square test with cross-tabulation, with a level of statistical significance p ≤ 0.05.Results: Obtained data showed a statistically significant difference in the knowledge of swimming coaches about first aid and CPR in relation to coaching experience (p = 0.025); in the knowledge of providing first aid and CPR between coaches who have a certificate of first aid and CPR and those who do not (p = 0.006) and in first aid and CPR knowledge between coaches who have renewed their first aid and CPR knowledge and those who did not (p = 0.045).Conclusion: Based on the findings of the present study, swimming coaches included in this research did not have enough knowledge and skills in first aid and CPR, which makes swimming programs unsafe. By obliging swimming coaches to acquire and constantly improve their knowledge and skills in first aid and CPR, the environment for all swimming programs would become safer.

  • Effects of observing real, animated and combined model on learning
           cognitive and motor levels of basketball jump shot in children

    • Abstract: Study aim: The purpose of the present study was to investigate the effects of observing the real, animated and combined model demonstrations on cognitive and motor learning of a basketball jump shot.Material and methods: Forty-five subjects with mean age of (11.03 ± 1.7) were randomly divided into three groups: real, animated and combined model demonstrations. Subjects were asked to perform basketball jump shot task during a four-step process. In total, participants shot 150 shots (10 shots in the pretest, 120 shots and 40 observations in the practice phase, and 10 shots in the posttest and the retention test). Accuracy scores and cognitive status were assessed as dependent variables.Results: Results showed that observation of real, animated and combined model demonstrations had significant effects on motor and cognitive learning of a basketball jump shot. Moreover, there was no significant difference between observing animated model and real model demonstrations at motor level, however, animated model demonstration group performed better than real model group at cognitive level. Finally, combined model demonstration group performed better than both animated and real model demonstrations groups.Conclusions: Results suggested that observing animated model demonstration is an appropriate approach for learning basketball jump shot even in children. It is also recommended to use animated model demonstration as a complement to real model.

    • Abstract: Study aim: In this study, it is aimed to find out the exercise preferences based on the Body Mass Index (BMI) and Body Weight Perception (BWP), and to determine the consistency between BMI and BWP calculated via the self-reporting method.Material and methods: The study was conducted total of 297 volunteers, included 174 females (Mage = 27.19 ± 9.94 years) and 123 males (Mage = 26.08 ± 10.15 years), who were members of the physical activity center. The height and body weight values were obtained based on the self-reports. BWP was assessed by asking “how do you describe your weight'” As a statistical analysis, the Pearson chi-square test and Kappa statistics were used.Results: It was determined that overweight/obese female prefered most the strength exercises, whereas, overweight/obese men, according to both methods, preferred the different kind of exercises (p < 0.05). When the mutual consistency of the BWP and BMI methods was compared, “average” level conformity was found in female, and “weak” level conformity was found in male (Female: κ = 0.48; p < 0.000; Male: κ = 0.21; p < 0.001).Conclusion: It could be said that the type and application protocol of the exercise has been related with the frequency and duration of the exercise for both of the methods. Besides, it could be said that there was a higher consistency among female participants at the level of participating to the exercise and they had similar exercise preference, frequency and duration.

  • The effect of personality characteristics combined with behavioral
           activation system (BAS) / behavioral inhibition system (BIS) and sport
           emotional induction on working memory

    • Abstract: Study aim: To investigate the interactive effects of behavioral activation or behavioral inhibition and induced pleasant or unpleasant emotions on working memory performance among young adults.Material and methods: Eighty participants (age 18–32 years) were randomly classified into 2 groups behavioral activation or inhibition and then sub-divided further via whether they received inductions in either pleasant emotions or unpleasant emotions. A pre-test measure of the working memory test was recorded and repeated after emotional induction.Results: The ANOVA analysis indicated significant effect of PERSONALITY factor (F1,76 = 4.760, p = 0.0322, ηp2 = 0.059) on results of the working memory test. The memory performance of the behavioral activation group that received positive emotion was better than the other groups, and the working memory performance of the behavioral inhibition group that received positive emotion was poorer than the other groups. Furthermore, the working memory performance of the behavioral activation group (positive emotion) was better than the other groups. Also, the working memory performance of the behavioral inhibition group (positive emotion) was poorer than the other groups.Conclusions: Finally, the findings support the different effects of the brain behavioral systems and sport emotional induction on working memory.

  • A modified digital functional reach test device using an ultrasonic sensor
           for balance assessment: A test of validity and reliability

    • Abstract: Study aim: Evaluation of dynamic balance is inferred to be compulsory for fall prevention in the elderly. Therefore, this study aimed to develop a modified digital functional reach test device using an ultrasonic sensor for balance assessment and to test validity and reliability of the newly developed tool to qualify psychometric properties.Material and methods: This study was a cross-sectional study of a convenient sample including 50 participants both males and females. Mean age of the participants was 51.20 ± 19.30 years. Reliability of the newly developed device was analysed using the intraclass correlation coefficient (ICC) and standard error of measurement (SEM). The criterion validity was also investigated using a yardstick mounted on the wall at a level of shoulder together with the MaxTraq® 2D motion analysis software. The modified digital functional reach test device using an ultrasonic sensor was correlated with the conventional FRT and the MaxTraq® 2D motion analysis.Results: The results presented that test-retest reliability of the modified digital functional reach test device was good reliability (ICC = 0.76) and low standard error of measurement (1.41) was found for test-retest reliability. The degree of agreement between the modified device, the conventional FRT, and the MaxTraq® 2D motion analysis was high (r = 0.71 and 0.77 respectively).Conclusions: The findings suggested that the modified digital functional reach test device using an ultrasonic sensor was a valid and reliable instrument for fall risk screening towards functional reach distance.

  • Comparison of movement velocity and force-velocity parameters using a free
           video analysis software and a linear position transducer during unilateral
           and bilateral ballistic leg press

    • Abstract: Study aim: This study compared movement velocity and force-velocity profile parameters measured by a free video analysis software program, with the use of a high-speed video recording, and a validated linear position transducer (LPT).Material and methods: Ten team-sports athletes performed double-leg and single-leg ballistic lower limb extensions on a leg press machine against a wide range of resistive loads. Each repetition was recorded by the LPT a high-speed camera (300 fps), and later analysed with a free video analysis software program.Results: Mean and peak movement velocity presented high reliability (ICC: 0.990 and 0.988, p < 0.001) and agreement between the two measuring systems (systematic bias: –0.06 ± 0.04 and –0.01 ± 0.03 m/s, respectively). Force-velocity profile parameters were also similar: maximum velocity at zero load (Vo: 1.79 ± 0.15 vs. 1.78 ± 0.12 m/s, p = 0.64), slope (b: –1585 ± 503 vs. –1562 ± 438 N · s/m, p = 0.43), maximum force at zero velocity (Fo: 2835 ± 937 vs. 2749 ± 694 N, p = 0.41) and maximum power (1274 ± 451 vs 1214 ± 285 W, p = 0.38). Both measuring systems could similarly detect the individual force or velocity deficit (p=0.91).Conclusion: In conclusion, a free video analysis software combined with a high-speed camera was shown to be a reliable, accurate, low bias and cost-effective method in velocity-based testing.

  • Rhythmic ability decline in aging individuals: The role of movement task
           complexity

    • Abstract: Study aim: To investigate age-related changes in rhythmic reproduction ability in relation to the complexity of the adopted movement task.Material and methods: A Stereophotogrammetric system was used to quantify individual rhythmic performances through motion analysis. Seventeen younger adult (age: 34.8 ± 4.2 yrs) and sixteen older adult (age: 69.9 ± 3.8 yrs) sedentary individuals volunteered for this study. Participants were administered a rhythmic test, which included three different rhythmic patterns to be reproduced by means of finger-tapping, foot-tapping and walking. Number of correct reproductions, time delays and rhythmic ratios were assessed and submitted to analysis of variance.Results: For all rhythmic parameters, age-related differences emerged about rhythmic patterns and motor tasks. Older adults showed reduced accuracy as compared to their younger counterparts with a marked tendency to speed up beats reproduction (p < 0.05). Increased movement complexity negatively influenced rhythmic ability, with worst performances in the walking task (p < 0.05).Conclusions: Complexity of the motor reproduction worsen rhythmic ability. Future research should focus on how specific rhythmic training with progressive movement task complexity could contrast this age-related decline.
