Fifteen athletes from short and middle distance branches of athletics who have been training regularly for at least 5 years and at least 5 days a week attended the study voluntarily. The athletes in this study were warmed up for 5 minutes at a speed of 8 km/h on a treadmill, followed by 5 minutes of passive rest. Completing 5 minutes of passive rest, the athletes were randomly sampled and any of the 50 lb, 60 lb, 70 lb, 80 lb resistance or non-resistance warm-up protocols consisting of 3 sets on the vertimax device were carried out. After warming up, 5 minutes of passive rest was given and then squat jump (SJ) and countermovement jump tests were performed. Repeated measures ANOVA test was conducted in the analyses of the measurements of jump distance and power of the athletes participating in this study both without resistance and after the applied resistances. Significant differences were observed in SJ and CMJ values after PAP warm-up without and with resistance (p < .05). The height and power values of SJ after PAP warm-up with 70 lb and 80 lb resistance bands were found significantly higher than those without resistance (p < .05). Furthermore, the height and power values of CMJ after PAP warm-up with 80 lb resistance bands were found significantly higher than the values of warm-up without resistance (p < .05). In conclusion, even though an increase in jump height and power values was observed with each resistance increment, significant increases in power and height values as a PAP response were achieved at 70 and 80 lb resistance for SJ and 80 lb resistance for CMJ.","PeriodicalId":51651,"journal":{"name":"Journal of Human Sport and Exercise","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141814516","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}

The duration of apnoea depends on the oxygen reserves, mostly derived from the air trapped in the lungs and airways. It is necessary to investigate whether erythrocyte and haemoglobin levels correlate with the achievable apnoea duration, considering their roles as oxygen binders and carriers in the blood. This study examines the correlation between erythrocyte and haemoglobin levels and apnoea duration in 12 sedentary males. Erythrocyte and haemoglobin levels were assessed through blood sample examination in a clinical laboratory by professional personnel, while apnoea duration was measured by remaining motionless in a swimming pool at a depth of 0.5 meters, with three measurements taken. Normality test results indicated that all data were normally distributed (p > .05). Pearson correlation test results revealed no correlation between apnoea duration and erythrocyte levels, haemoglobin, or haematocrit (p > .05). From the research findings, it can be assumed that these three blood biochemical variables cannot be categorized as oxygen reserves and only function as oxygen transportation media.","PeriodicalId":51651,"journal":{"name":"Journal of Human Sport and Exercise","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141818937","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}

The search strategy was carried out in four electronic databases (PubMed®, Scopus, SPORT Discuss and Web of Science) using the PRISMA-ScR methodology (extension for Scoping Reviews). 78 articles were included for the final analysis. Most studies analysed female athletes (56.4%), in a cross-sectional design (85.9%), with group comparison (60.3%), bivariate analysis (66.7%) and application of test batteries (91%) of anthropometric (62.8%) and physical-motor (56.4%) characteristics. There were few studies that adopted a multidimensional (20.5%) and retrospective/longitudinal approach (11.5%), evaluated psychological skills (7.7%), subjective coach analysis (25.6%), motor coordination (9%), maturation (9%) and sociocultural characteristics (5.1%). Thus, talent identification in volleyball generally uses batteries of tests to discriminate between skill levels, mainly using physical tests (anthropometric and physiological measures), but the evidence for their validity in predicting future performance and discriminating skill levels is limited. Future research should adopt multidimensional and longitudinal approaches, combining objective and subjective indicators of sporting potential of young volleyball athletes.","PeriodicalId":51651,"journal":{"name":"Journal of Human Sport and Exercise","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141821577","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}

This study aimed to investigate the changes in health-related fitness concerning age among adolescent boys. A sample of 80 students aged 13-16 from Upashahar Maddhamic Viddalay, Jashore, was selected at random to assess health-related fitness components including low back and hamstring flexibility, abdominal muscle strength endurance, upper-body strength (chin-ups), and body composition. Fitness was assessed by measuring the components of Health-Related Physical Fitness as prescribed by AAHPERD (1984). In addition to these fitness components the body composition of the subjects was assessed by measuring triceps and subscapular skin folds, all their parameters were the criteria for measurement in the present study. Statistical analyses, including mean values, standard deviation, and 't' tests (where table value at .05 levels for of 38 was 2.02), were conducted to determine significant differences across age groups. The results indicate that abdominal muscle strength endurance, as measured by sit-ups, showed significant differences at .05 level between age groups, with class VII and IX exhibiting higher mean values compared to class VIII and X. This suggests that factors such as academic pressure and lifestyle choices may impact physical fitness levels among adolescent boys. However, when considering upper-body strength, flexibility, and body fat percentage, the study did not find significant differences between age groups. This indicates that these aspects of health-related fitness may be less influenced by age alone and more by individual factors or environmental influences.","PeriodicalId":51651,"journal":{"name":"Journal of Human Sport and Exercise","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141655342","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}

The present study aimed to investigate a method for detecting the release instant from data collected using a single inertia measurement unit (IMU) in shot put. Two male shot putters participated in the study. Each participant performed six competitive throws with a 9-axis IMU (100 Hz) attached to the back of the participant’s throwing hand. Three different methods were examined from IMU data: threshold values of resultant acceleration, waveform of resultant acceleration, and waveform of the angular velocity around the radio-ulnar axis of the hand. The release instant as a true value was obtained from the video recorded in sync with the IMU, and the error of the release instant detected from the IMU was calculated. The final number of trials analysed was four for participant A and six for participant B. As results, there were various cases where the threshold value of acceleration did not exceed the value depending on the participant and trial, and the release instant could not be detected. The release instant detected from the moment the acceleration decreased based on the acceleration waveform had a large error (4.00 ± 2.26 frames). The release instant, which was detected from the moment when the angular velocity became negative based on the angular velocity waveform, was detected in all trials for both participants, and the error was low (1.20 ± 0.92 frame).It was found that utilizing the detection of dorsiflexion timing of the wrist joint, with the angular velocity around the rotational axis parallel to the radio-ulnar axis of the hand as a cue, proved to be a highly accurate approach for determining the release instant.","PeriodicalId":51651,"journal":{"name":"Journal of Human Sport and Exercise","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141657253","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}
