  • Disparities in Physical Activity and Depressive Symptoms among Young
           Adults in the Early Stage of the COVID-19 Pandemic

    • Authors: Xiaoxia Zhang, Samantha Moss, Xiangli Gu
      Pages: 1 - 9
      Abstract: Background of the study: The COVID-19 pandemic has deeply impacted people’s daily lives, while the influence on behaviors and mental health among college students at the early stage of this pandemic is rarely studied. Objective: This study examined the impact of the COVID-19 pandemic in the early stage on college students’ physical activity (PA), sedentary behavior, and depressive symptoms and its impact on sex and ethnic disparities in these outcomes. Methods: Using a cross-sectional design, 111 college students were recruited, and the data were collected before COVID-19 (n = 64) and in the early stage of the COVID-19 pandemic (n = 47), respectively. All participants completed a survey measuring depressive symptoms and wore an accelerometer to monitor PA behavior (light PA [LPA], moderate-to-vigorous PA [MVPA]), and sedentary behavior. Results: More MVPA engagement and lower levels of depressive symptoms were observed in the early-stage COVID-19 group compared to the before-COVID-19 group. The magnitude of the sex and ethnicity disparities in PA and depressive symptoms were reduced in the early-stage of the COVID-19 pandemic. Conclusion: Understanding college students’ behaviors and mental health in the midst of a global crisis can be useful to determine appropriate strategies to address health and wellness in the chance of the lockdown returning and to further promote this vulnerable population’s physical and mental wellness.

  • Effect of Clubbell Exercises on Shoulder Kinematics in Female Handball

    • Authors: Sibi Walter, Amin Daneshfar, Carl Petersen
      Pages: 10 - 15
      Abstract: Background: Clubbells were popular shoulder exercise equipment used during the 17-18th centuries. Currently there is a resurgence in the use of clubbells to strengthen the shoulder rotators, but there are no studies to prove their effectiveness on shoulder kinematics. Therefore, this study aimed to find out if clubbell exercises had any effect on glenohumeral rotational range of motion (ROM) and shoulder rotator strength. Methods: Using a randomised control study design, female handball athletes (n=15) were voluntarily recruited and were assigned randomly to either a handball training only group (HT) (n = 8, age 25±7 y, height 1.77 ± 0.11m, mass 76 ± 15 kg,) or a shoulder exercise group (SE) (n = 7, age 27±8 y, height 1.78 ± 0.12m, mass 79 ± 15 kg). The SE group underwent an exercise programme (8 weeks, 3 days/week, 20 min/day) using clubbells. The ROM and muscle strength were assessed at baseline and at the end of weeks 2, 4, 6 and 8. Results: After eight weeks, comparison between groups showed that the SE group’s dominant arm internal rotators muscle strength improved (28±5 to 33±7 Nm) significantly (p<0.05). Within the SE group, internal rotation ROM, internal rotators, and external rotators muscle strength all significantly (p<0.05) improved. Conclusions: Clubbell exercises increases internal rotation ROM and shoulder rotators muscle strength. Therefore, it is suggested that handball athletes could use clubbell exercises to improve their shoulder rotational ROM and strengthen the shoulder rotators whereby reducing shoulder injury risk.

  • Effect of Plyometric Training Conducted in Aquatic Medium on Speed and
           Explosive Strength of the Athletes

    • Authors: Sandip Sankar Ghosh, Raju Biswas
      Pages: 16 - 26
      Abstract: Background: Plyometric training (PT) are performed in different hard surfaces like dry land, hard court or grassy turf which is at the same time susceptible to muscle and joint injury of the lower limbs. To avoid this risk Aqua-based training gradually has become popular to the trainers. Therefore, in the present study the PT were conducted in an aquatic medium. Objective: The purpose of the present study was to investigate the effect of Aquatic plyometric training on speed and explosive leg strength ability of the young Indian athletes. Method: This study was quasi-experimental in nature. Twenty-four (N = 24) athletes aged between 14-16 years were selected. They were equally grouped into two: i) Aquatic Plyometric Training Group (APTG, N=12), and ii) Control Group (CG, N=12). Both the groups were involved in regular physical activity as usual in their academy which was not under the control of the researchers, however, in addition to that APTG underwent an aqua-based Plyometric training for fourteen weeks. The dependent variables were speed and explosive leg strength. Baseline (pre) and post intervention mean values for APTG and CG were analyzed through ANCOVA. The F-values were tested at p<0.05 level of significance. Results: The APTG improved significantly with respect to the CG in speed (F = 70.890; p < 0.00001) and explosive leg strength (F = 32.553; p < 0.00001). Conclusion: Aquatic Plyometric Training was found as an effective training means for the development of speed and explosive leg strength of the athletes belongs to the age group of 14-16 years.

      Pages: 27 - 41
      Abstract: Background: Altering moderator variables during a jump rope training (JRT) program can provide a novel training modification that can be used to modify the specific training outcomes. JRT is commonly implemented as a traditional game activity in many countries as an old culture of physical activity in school-age participants (SAP). However, strength and conditioning professionals need to know how JRT moderator variables affect these health- and physical fitness outcomes. Thus, an evidence-gap map (EGM) could provides a clearer picture of the design of an appropriate JRT based on scientific evidence. Objective: the purpose of this systematic review secondary analysis was to assess the moderator variables related to JRT effectiveness for health and physical fitness-related outcomes in SAP. Method: literature searches were conducted in the following electronic databases: PubMed, Web of Science and SCOPUS. The PICOS (participants, intervention, comparators, outcomes, and study design) approach was used to rate studies for eligibility. An EGM was constructed to graphically represent the body of evidence and the current research gaps. Results: 10,546 records were initially identified and finally, 8 studies were considered. A total of 186 participants were analysed in the intervention groups (16 groups). Five of Eight studies measured health-related parameters and five of eight included fitness-related parameters. Conclusion: rope weight (e.g., weighted rope i.e. 695 g), adequate post-exercise recovery strategies (e.g., dark chocolate supplementation), type of jump (e.g., freestyle), and total number of jumps, can be

  • Physical Activity and Post-COVID-19 Syndrome in Older Adults: A Systematic

    • Authors: Tutiek Rahayu, Kartika Ratna Pertiwi, Wara Kushartanti, Novita Intan Arovah
      Pages: 42 - 52
      Abstract: Background: Physical activity (PA) may play a significant role in managing post-Coronavirus Disease (COVID)-19 syndrome, a significant public health concern among older adults. This study aimed to systematically review the evidence on post-COVID-19 symptoms, signs, risk factors, and the effects of PA programs in managing post-COVID-19 syndrome among older adults. Method: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendation. The systematic search was conducted in August 2022 using Scopus and MEDLINE (via PubMed) databases. Results: There were 51 documents screened, among which 10 (7 observational and 3 experimental studies) met the selection criteria. The reported post-COVID-19 symptoms and signs associated with physical health included dyspnea, fatigue, diarrhea, and sarcopenia, abnormal lung function, cardiac pathology, immunological changes, reduced physical performance, respectively, while those associated with mental health included depression, poor concentration and memory, and anxiety. Patients with higher body mass indexes were more likely to experience more symptoms. Older patients had greater difficulties in performing daily activities and mobility. A multidisciplinary-based PA program is suggested to be feasible and effective in improving fatigue, ability to walk, balance, and cognitive function. For patients with sarcopenia, a low-intensity aerobic training exercise appears to improve muscle strength, kinesiophobia, and quality of life. Conclusion: Various post-COVID-19 symptoms have been reported along with their risk factors, and PA programs are potentially used for managing these symptoms. More research, however, is recommended to explore the PA program for specific post-COVID-19 symptoms.

  • Cardiorespiratory Fitness and Leg Muscle Power in Relation to Abdominal
           Adipose Tissue in Adolescents

    • Authors: Danladi Ibrahim Musa, Oluwatoyin O. Toriola, Mohammed N. Abubakar, Sunday U. Jonathan, Daniel Iornyor, Agbana Busayo Emmanuel
      Pages: 53 - 59
      Abstract: Background: Abdominal adiposity is associated with high risk of cardiometabolic diseases. Waist circumference has been used as a surrogate measure of abdominal adipose tissue in both youth and adults. Objectives: The present study evaluated whether cardiorespiratory fitness and leg power (LP) were independently associated with abdominal adipose tissue in 12-16-year-old Nigerian adolescents. Methods: This cross-sectional study comprised 2047 (1087 girls and 960 boys) adolescents who were evaluated for cardiorespiratory fitness and leg power. The cardiorespiratory fitness and leg power were assessed using the progressive cardiovascular endurance run (PACER) test and the vertical jump (VJ) test, respectively. Abdominal adiposity was evaluated with the waist circumference (WC). Regression models controlling for age and maturity status were used to assess the association of fitness and LP with WC. Results: Low leg power had significant negative association with the risk of abdominal adiposity in both girls (β=-0.307; p<0.001) and boys (β=-0.262; p<0.001). The observed relationship was independent of fitness, whereas the relationship between fitness and risk of abdominal adiposity was partly determined by leg power. Conclusion: Leg power and fitness were independently associated with the risk of abdominal adiposity in adolescents, but the association of leg power was stronger in girls. Health promotion efforts targeting reduction of abdominal adipose tissue should also include muscular power training type activities in addition to endurance-related activities.

      Pages: 60 - 70
      Abstract: Background: Obesity is a major public health issue in the United States (U.S.), affecting an estimated 78 million US adults. Aerobic exercise (AE) is recommended by the American College of Sports Medicine to prevent and treat obesity, yet the effects of AE on circulating hunger hormones including acylated ghrelin and its biological catalyst, ghrelin o-acyltransferase (GOAT) are less known. Objectives: We investigated the effects of AE on circulating concentrations of appetite regulating hormones and GOAT in a pilot sample of adults classified with normal weight (NW) and obese (OB) body weight status. Methods: Using a quasi-experimental design, nine adults with NW (n=4, body mass index [BMI] = 21.3±1.2 kg/m2) and OB (n=5, BMI = 38.9±6.2 kg/m2) body weight status completed a preliminary health/fitness assessment. Participants returned to the laboratory on three separate occasions, separated by ≥ 48 hours to perform cycle exercise at 30% and 60% oxygen uptake reserve (VO2R) or a seated control session with no exercise for 40 min. Fifteen mL of blood was taken pre-and-post exercise and control and were assayed in duplicate. Nonparametric procedures determined whether mean rank differences existed between NW and OB for acylated ghrelin, leptin, insulin, and GOAT in response to exercise and control. Alpha levels were set a priori to p <0.05. Results: Significant mean rank reductions were found in GOAT after compared to before AE and control for NW and OB (p<.05). Significant mean rank differences were found in acylated ghrelin after compared to before performing AE at 60% VO2R in NW and OB (p<.05); however, differences were not observed between NW and OB (p>.05). Conclusions: Our findings reveal the first available data regarding the effects of AE on GOAT, with NW and OB experiencing equivocal changes pre-to-post AE at 60% VO2R, and in response to a seated control session.
