Background of Study: Competence in motor performance skills is important in enabling children to be physically literate. Plyometric-based training has been suggested as an effective means to enhance motor performance skills in young athletes. However, no studies have reported the effects of a whole body plyometric-based program integrated into physical education on motor performance skills with young children. Objective: This study aims to examine the effect of a plyometric-based program on primary school students’ motor performance skills, upper and lower body muscular power, and reactive strength index. Method: The sample was composed of 61 primary school students, 29 girls and 32 boys, aged 7–8 years old, from two second-grade Physical Education (PE) classes. Both groups participated in their regular eight-week PE lessons (50-minute classes twice a week). During the study, the plyometric group performed a plyometric-based program in the 15-minute warmup of each class, while the comparison group performed regular warmup activities. Student’s motor performance skill proficiency, reactive strength index, lower and upper body muscular power were assessed before and after the eight weeks of PE lessons. The data were analysed using a two-way analysis of variance, followed by pairwise comparisons with the Bonferroni adjustment. Results: The data analysis indicated significant increases in motor performance skill proficiency, upper and lower body muscular power in the plyometric group vs comparison group (p ≤ 0.05). Conclusion: These results suggest that including a plyometric-based program in the PE warmup phase of the lessons may improve motor performance skills and muscular power in primary school students.

Background: Patients with cerebral palsy (CP) may necessitate long-term treatment and monitoring of their condition, not only during the period of development but also during adulthood. Objectives: This systematic review aimed to analyze evidence from randomized controlled trials (RCTs) that have investigated the effect of treadmill training on walking ability in adults with cerebral palsy. Methods: RCTs were identified and selected systematically, with appropriate keywords applied in four scientific databases (Medline, Scopus, the Cochrane Library, and the Physiotherapy Evidence Database) and one bibliographic search engine (Google Scholar) from January 1980 to September 2021. Two assessors extracted and analyzed data from relevant RCTs published in English and then independently rated those studies for risk of bias with the Risk of Bias (RoB 2) tool. Results: Out of the 96 studies that were initially identified, 93 were excluded, as these either did not meet the inclusion criteria or were duplicates. Three clinical trials were finally included, characterized by some concerns and a high risk of bias (RoB 2). Meta-analysis was only performed for the maximum distance in the ‘6-minute walk for distance test’, due to differences in the remaining outcomes utilized between studies. Overall, there was evidence of some concerns and high risk of bias that treadmill training did not significantly improve the walking ability in adult patients with CP relative to the control conditions. Conclusion: More high-quality RCTs are required, examining the effectiveness of treadmill training on different aspects of walking ability such as gait speed, endurance, and energy expenditure.

Background: The importance of vision and its impact upon an athlete’s performance has long been recognized by elite athletic communities. In recent decades, stroboscopic training methods have been developed to help train athletes from a visual, perceptual, and cognitive perspective using strobe glasses. Objective: Herein a comprehensive literature review was conducted to investigate the effectiveness of strobe glasses in training collegiate and professional athletes. Methods: This comprehensive literature review investigates the origins, attention influences, tasks, practitioner takeaways, and cost feasibility of stroboscopic visual training.Results: The findings from this review show promise of benefits from utilizing strobe glasses during training scenarios, particularly for improving fast or impulsive tasks. Strobe glasses can be accommodated into varying sporting environments and training regimens while being affordable to athletic, coaching, and training departments or centers. Studies investigating the direct influence of stroboscopic training on subsequent performance demonstrate viable methods for strengthening fundamental visual abilities. Notably, these fundamental abilities have been shown to correlate with improved game performance. Though early results are promising, there are still significant areas for further research and more comprehensive designs of stroboscopic training studies. Conclusion: This review highlights potential benefits and existing research gaps concerning the use of stroboscopic eyewear as an intervention method in sports. The delineation of optimal applications for strobe glasses is undetermined; however, information presented in this review can be meaningfully applied by coaching practitioners who are considering adopting the technology.

Background: The performance outcome model in qualitative technique analysis can determine the mechanical interactions between a performance outcome and the factors that yield such results in sports techniques. Very little attention has been received for badminton forehand shots for such model work, considering the significance of this technical skill as fundamental to play badminton and as important offensive shots. Objective: This study proposes a performance outcome model that associates performance criteria and relevant mechanical variables in the badminton forehand shot technique. Methods: Literature review provided the basis of model development. The Literature research in this paper was conducted in the following databases; PubMed, ScienceDirect, Google Scholar Medline, Pedro, and Cinahl. An additional search (including relevant grey literature) was also done on the internet through ResearchGate. Relevant literature research related to the keywords such as biomechanics of badminton, badminton forehand shot, biomechanical analysis, badminton performance, racquet sports, performance indicators, technique analysis and technique models were included and reviewed. Results: The results managed to present a synthesis of the literature review and provided constructive discussions as a basis to propose a performance outcome model that illustrates mechanical interactions that contribute to badminton forehand and shot technique performance. Conclusions: This model manages to find mechanical relationships and allows for a better grasp of understanding the association between performance criteria and mechanics in the badminton forehand shot technique, which is bases on the kinetic chain principle through the body segmental coordination.

Background: The imposed stay-at-home restrictions with the coronavirus (COVID-19) pandemic disrupted daily routines and impacted some population groups more than others. One such group included university students who were forced to adapt to online classes reducing face to face interactions. The uncertainty associated with this change may have created a sense of anxiety and fear towards the virus. Objective: The objective of this study was to measure the level of fear associated with COVID-19 in Canadian undergrad university students and the influence fear may have on their health-related behaviours during an ongoing pandemic. Methods: Students enrolled in four large universities in the province of Alberta were invited to complete an online Fear of COVID-19 Scale (FCV-19S) from January 4th to February 15th, 2021. Results: Undergraduate students (n=680; 73.4% female) with a mean age of 23 (SD 5) years had an average FCV-19 score of 17.1 (SD 6.1) out of 35. Many students (60%) categorized their fear in the moderate range and females were more likely to have a higher FCV-19 score (p<.05) than males. Increases in alcohol and substance use, sleeping and eating behaviours were significantly associated (p<.05) with higher FCV-19 scores (p=.047; p=.000; p=.000). Most student’s smoking behaviour (80.5%) remained the same, however physical activity decreased. Conclusion: In summary, students showed a moderate level of fear associated with COVID-19 during the pandemic, and those with greater levels of fear reported more negative heath behaviour choices. These results highlight that continued restrictions during the COVID-19 pandemic continue to negatively impact student’s health behaviours.

Background: Examining students’ levels of physical activity is important because these students will be the future leaders of their communities. Objectives: The aim of this study was to generate primary information and describe the lifestyle behavior patterns considering physical activity prevalence among gender-related Lebanese college students. Methods: The study involved 600 students (346 Men, 254 Women with mean age 23.5 ± 3.96). The participants’ levels of physical activity was examined by utilizing the International Physical Activity Questionnaire (IPAQ). The over-all level of physical activity including the four-lifestyle fields: work, transportation, home and gardening, and leisure-time, was presented as metabolic equivalent-min per week (MET-min/week). Results: Findings indicated 22% of students with high physical activity level, 61% and 17 % with moderate and low levels respectively. Based on activity Intensity, 47% (n= 282) of students were engaged in vigorous activity, while 45.2% (n= 271) were engaged in moderate activity, and 68.3% (n=410) were engaged in walking activities. Average time spent sitting for the whole sample was 6.23 daily hours. The level of weekly total physical activity expressed in metabolic equivalent represented 2970.5 MET/min/week in males and 2719.5 MET/min/week in females. Conclusion: In general, Lebanese universities students were equally active, with trivial supremacy for males. Lebanese university students met the (WHO) recommendations for physical activity (>150 min/week of moderate activity or > 75 min/week of vigorous activity or an equivalent combination of both activities). Physical Activity must be developed by the provision of physical activity classes in the university curriculum and extracurricular activities.

Background: Some studies show that wearing compression garments (CGs) improves balance performance. However, the overall evidence supporting their use for balance improvement is inconclusive. Objective: This study aimed to further explore the effect of CGs on balance. Method: Using a cross sectional within subjects repeated measures design fourteen participants (27 ± 3 years) completed three trials for each of four balance tests, under three conditions: compression garment, no garment, and sham. Subjective performance and garment rating scores were also collected following each test condition. A repeated-measures analysis of variance was performed to compare derived variables between conditions for each balance test. Results: No significant differences were found across conditions or tests for either balance performance or subjective measures. Conclusions: This study demonstrated CGs did not influence dynamic or static balance performance in healthy young males. Further, in contrast to other research this study did not demonstrate an effect of compression garments on dynamic or static balance in healthy young males. However, it remains that CGs may provide benefit in other populations including those with balance and movement deficit disorders.

Background: Exercise power output, and resulting fatigue, is regulated based on central and peripheral sensory input. Whether exercise mode, specifically, contributes to this regulation remains unexplored. Objective: This study was designed to determine if differences in markers of fatigue would be present during two time trials of similar duration and intensity, as a result of exercise mode (cycling and rowing). Method: In a randomized crossover design, nine subjects completed the two 7-min time trials, on different days. Exercise power output, heart rate, rating of perceived exertion, and blood lactate measurements were analyzed using repeated-measures ANOVAs. Results: There was a significant interaction between mode and time for power output (p =.02), but no significant differences between matched time points were observed for any of the dependent variables used to assess fatigue (p >.05). Conclusion: Similar levels of heart rate, perceived exertion, and blood lactate for time trials on different modes, but with the same duration and directed intensity, suggest that in a laboratory environment, exercise is regulated more by physiological disturbance and sensory cues than by exercise mode. These findings support the sensory tolerance limit of exercise fatigue.

These findings support the sensory tolerance limit of exercise fatigue.","PeriodicalId":36327,"journal":{"name":"International Journal of Kinesiology and Sports Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46167019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background of Study: Differing movement onset thresholds have been used when analyzing the squat jump movement from force-time data obtained from a force platform. This makes comparisons difficult between investigations as this will impact the amount of the force-time curve that is analyzed. Objective: Thus, study examined the effect onset threshold had on kinetic and kinematic variables used in the assessment of the squat jump. Methods: Using a within-subject study design, fifteen recreational trained males performed three trials of squat jumps on a force platform. Each trial was analyzed using one of five different onset thresholds (2.5% SW, 5% SW, 10% SW, 20N, 5SD). Force, velocity, and power, as well as time to peak force, velocity, power and jump height were calculated using the vertical force data obtain from the force plate. Reliability was assessed using intraclass correlation coefficients and coefficients of variation. A one-way ANOVA was used to examine the impact of onset thresholds on all variables of interest. Results: The use of 10% SW and 5SD met minimum reliability criteria for all variables. Temporal related variables were impact to the greatest extent by differing thresholds with large (d > 1.20) significant differences. 10% SW showed the highest mean values of force, velocity, and power. Conclusions: The use of 5SD of the weighting phase is recommended as this showed high level of both absolute and relative reliability in addition to preserving a large portion of the force – time curve to be used in the analysis.

Background: “Exercise is an activity to improve technical and physical competence of athletes”, most sports require an excellent physical aspect to win. Aerobic endurance is an essential point in the preparation of a wheelchair tennis training program. Aim: This research is to validate the circuit training program and test the exercise program on the aerobic endurance of wheelchair tennis athletes. Method: This research is development research with qualitative and quantitative approaches. Participants are wheelchair tennis athletes with ten males and four females, height 156-167± cm, weight 50-70± kg, age 31-35. Participants in the program validation were seven nationally licensed physical fitness trainers. The first stage qualitatively examines documents in articles, ebooks, textbooks to design the program. The second stage quantitatively applies the Delphi technique to assess the prepared training program. The third stage analyzes the assessment results with the content validity ratio formula and, the fourth stage tests the exercise program for six weeks. The instrument used is a multistage fitness test. Results: It has been found that the assessment items from seven experts show the content validity ratio value is 1.00, so it can be categorized as having good content validity. It has been found the mean posttest (N=14, M=249.14, SD=16.033) and posttest (N=14, M=241.71, SD=17.166). It has been found that hypothesis testing using paired samples t-test analysis (p=0.000<0.05). Conclusion: the circuit training exercise program has good validity, then based on the effectiveness test, there is an increase in the aerobic endurance of wheelchair tennis athletes.
