This study investigated distinct visual processing patterns among Thai elite athletes in gymnastics, soccer, and esports, utilizing visual P300 event-related potentials (P300 ERPs). Forty-two female athletes (14 gymnasts, 14 soccer players, and 14 esports athletes) participated. Visual P300 ERP responses were stimulated using the visual oddball paradigm. One-way ANOVA was employed to assess significant differences among the groups in P300 ERPs data, including amplitude and latency of waveforms, response time, and accuracy rate. Significant differences were found across the groups in various parameters. Esports athletes exhibited longer P300 ERP latencies at the frontal electrode sites compared to gymnasts (p = 0.01), suggesting slower visual processing in the frontal brain regions. Gymnasts demonstrated the fastest response times, significantly quicker than esports and soccer players (p < 0.01). In contrast, soccer players exhibited the highest accuracy rate (p = 0.03). These findings underscore athletes' diverse visual processing strategies in different sports contexts, reflecting sport-specific adaptations. Understanding these distinct visual processing patterns can guide targeted interventions aimed at improving cognitive abilities and decision-making processes among elite athletes, ultimately contributing to better overall performance.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"17 5","pages":"1595-1604"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11728593/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142978502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forty subjects were recruited for this study. Each subject sat at a workstation under the 3 different sitting positions for ten minutes for each condition. During this time, the subjects typed a prompt for seven minutes and rested for the remaining 3 minutes. This was repeated for each position. Inclination angles and electromyography data were collected at different intervals during each trial. The results showed a significant difference in mean inclination angle among the three positions in the pain group (p<0.01). The head and neck inclination angles were higher in the rear sloped position compared to the forward slope (p<0.001). In the pain group, there was no significant change in the mean muscle activity in the UT in the forward slope as compared to the rear slope and neutral positions (p ≤0.01). The results of this study suggest that the forward sloped position provides a favorable body alignment compared to the other positions which may then lead to less unwanted muscle activation.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"17 1","pages":"1280-1293"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11728583/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142978590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Healthy male participants (n = 16) performed a graded exercise test on a cycle ergometer to establish their peak power output (PPO). In subsequent visits, participants completed five different 8-minute cycling interventions, with intensities randomly assigned to one of three counterbalanced orders. HPT and PPT were applied to the thigh and forearm two times before and after each cycling intervention. Additionally, there was a notable effect of intensity on PPT in the thigh, with significant changes at intensities of 90% (p = 0.024) and 100% PPO (p = 0.003). In the forearm, repeated measures ANOVA indicated that there was no significant interaction or main effect for intensity and time. Similarly, for HPT, the analysis did not show significant interaction or main effects for both intensity and location. This study was the first to examine EIH using an 8-minute cycling intervention on a cycling ergometer at individualized intensities. Higher intensity cycling sessions generated EIH locally in the thigh using PPT. A short but high intensity cycling intervention may have clinical relevance, as it can provide an intervention to reduce localized pain immediately after exercise using a pressure pain stimulus.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"17 7","pages":"1337-1351"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11728575/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142978425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PPE negatively impacts performance. Greater strength and power could alleviate performance decrements due to the extra load, termed the tactical deficit (TD). The purpose of this study was to examine whether lower-body strength or power related to the TD in civilians performing police tasks. Twenty participants (12 men, 8 women) completed baseline tests, including: standing broad jump (SBJ); relative SBJ; absolute and relative isometric leg/back dynamometer (LBD) and one-repetition maximum hexagonal bar deadlift (HBD). In two other sessions, participants completed four police tasks, either unloaded or loaded (PPE=~8-10 kg), in a counterbalanced order: vertical jump (VJ), 75-yard pursuit run (75PR), 74.84-kg body drag, and 500-yard run. The VJ was also used as a power metric, with peak anaerobic power and power:body mass (P:BM) derived. Paired samples t-tests investigated differences between unloaded/loaded conditions for each task for each sex. Independent samples t-tests compared the sexes. Pearson's correlations derived relationships between strength and power tests with each task TD for each sex. Load negatively impacted task performance (p≤0.011); males generally outperformed females (p≤0.044). Superior SBJ, relative SBJ, VJ, P:BM, and absolute and relative HBD related to a smaller 75PR TD (r=-0.582 to -0.838). Greater absolute and relative HBD related to a lower body drag TD (r=-0.576 to -0.618) in men. For women, the relative SBJ related to a smaller VJ TD (r=-0.727).

This study examines if it is feasible and beneficial for PWP to perform high-intensity exercise in a CBP. Seven subjects diagnosed with Parkinson's disease participated in a multimodal CBP twice a week for six weeks while wearing heart rate (HR) monitors to help maintain an HR of 70-85% of the age-predicted maximum. Subjects completed pre- and post-testing, including Functional Gait Assessment (FGA), Five Time Sit to Stand (5xSTS), Timed Up and Go (TUG), and Activities-Specific Balance Confidence Scale (ABC).

Findings indicate a DW elicits a higher maximal HR and higher submaximal HR, VE, and oxygen uptake values than TW during CPET in youth, although no differences in VO2 peak were observed.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"17 4","pages":"1530-1539"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11581380/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142686565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
