Participants were randomly assigned to either a training (n = 17) or control group (n = 21). Participants' diets were not altered, only the exercise regime was manipulated to isolate effects. The exercise group completed a periodized running program consisting of 20-30 min, over an agreed route, three times per-week, whilst the control groups refrained from daily exercise. Participants were screened at the end of the study for 1,000 gene variants using a DNA test kit. Results demonstrated a significant reduction in body mass, within the exercise, compared to the control group (p = .002). This reduction in body mass varied significantly (p = .024) between individuals within the exercise group. Moreover, genetic analysis identified 17 single nucleotide polymorphisms (SNPs) associated with this variation (r2 = .74; p < .001). These findings indicate that individuals with specific alleles are better predisposed to weight-management, compared to their counterparts, following an exercise program. This study helps to bridge the gap between population health and exercise science and can inform research in the application of genetics to help develop individually tailored health interventions.","PeriodicalId":54491,"journal":{"name":"Research Quarterly for Exercise and Sport","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are many types of SS, and few studies have compared which SS concepts are more strongly associated with PA and QoL. This exploratory cross-sectional study examined the association between several types of SS provided by other people in group exercise oncology classes and PA and QoL among adults living with cancer. It was hypothesized all types of SS would be positively associated with PA and QoL. Participants (N = 72) completed a questionnaire assessing 11 SS predictors, five QoL outcomes, and one self-reported PA outcome, and wore a Fitbit to assess step count for 1 week. Hypotheses were tested using multiple regression. Reassurance of worth support predicted self-reported moderate-to-vigorous PA (R2 = .07, p = .03). Relatedness thwarting negatively predicted general (R2 = .07, p = .03) and social well-being (R2 = .10, p = .01). Social network predicted physical well-being (R2 = .07, F(1, 66) = 4.93, p = .03). There were no significant SS predictors of the other outcomes. Group exercise oncology programs should train instructors to promote reassurance of worth by recognizing or facilitating other participants to recognize participants' PA competence and skills, encourage developing social relationships by creating opportunities to connect over time, and minimize relatedness thwarting by promoting belonging and inclusion. Future research should compare different types of SS in larger samples and diverse populations of adults living with cancer.","PeriodicalId":54491,"journal":{"name":"Research Quarterly for Exercise and Sport","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Agility T-Test performance does not significantly differ between the two categories (F-value = 0.537, p > .05).

A battery of tests (attention, working memory, time reproduction, pattern recognition, temporal equivalence, technical ability, and decision-making) was administered to verify the relation between various cognitive abilities, on-ice performance, and the baseline score on the NeuroTracker, which is claimed to solicit multiple cognitive functions. On-ice performance indicators were game-related statistics: games played, points (mean per game), on-ice goals differential, and draft rank. <b>Results</b>: Results show that the baseline score on the NeuroTracker is not associated with draft ranking, nor is it able to predict which players will perform best based on game-related statistics. However, the NeuroTracker baseline score does correlate with various tests involving working memory and attention. <b>Conclusion:</b> Currently, NeuroTracker is not specific enough to allow talent identification among same-level elite athletes in ice hockey.</p>","PeriodicalId":54491,"journal":{"name":"Research Quarterly for Exercise and Sport","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10189564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
