Because triathlon has great educational potential, this case study sought to explore whether a modified Physical Activity Enjoyment Scale (PACES) survey can be used as a suitable measure of enjoyment of physical activity in elementary school children when applied to a sports-specific task such as triathlon. Methods: The sample consisted of 12 female elementary school students (10.3 ± 1.3 years) from an inner-city high school. A modified triathlon program was delivered for one hour per week over a four-week duration with a modified PACES survey distributed each week. Survey responses were coded and then averaged over the four-week duration with the children’s responses subsequently analyzed using a Wilcoxon Signed Ranks Test to examine differences in the coded characteristic response scores of the survey. Further comparisons were made using a Student’s t-test and a coefficient of variation (CV). Results: A greater sense of pleasure and fun was reported by the participants at the conclusion of the four-week triathlon program while there was no change in the children’s sense of excitement (p < 0.5). Characteristic responses to ‘neutral’ decreased with a simultaneous increase in the ‘slightly enjoyed’ response when viewed over the four-week duration of the program (p <0.001) Conclusions: This PACES case study was designed as a feasible, simple, and innovative approach to monitor enjoyment levels in elementary school children who participated in a triathlon program. Overall, the positive enjoyment reported from this simple, low-cost intervention could be used to inform the development of future sport-specific elementary school programs.","PeriodicalId":74674,"journal":{"name":"Research Directs in health sciences","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136112905","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}

In the exercise condition, participants walked or ran on a treadmill at 75-85% of their maximum heart rate for 40 minutes. Under the control condition, participants stood for 40 minutes to control for orthostatic effects. Biomarkers were quantified from saliva collected before, 1 minute after, and 45 minutes after the exercise and control condition.\u0000Results: The change in biomarkers from baseline values (+1 min and + 45 min) between exercise and control conditions showed that compared to the control condition, the acute exercise bout significantly increased sAA CRP at +1min at +45 min and in IL-1β +45 min.

This work largely focuses on adults. However, there is an inverse relationship between cellphone use and age. Because their cellphone use may be different from adults, understanding these relationships in younger individuals is warranted. \u0000Methods: High school students (N = 17) completed an online survey consisting of validated items assessing self-reported cellphone use, physical activity, sedentary behavior, anxiety, and grade point average. Correlation analyses were then performed assessing the relationships between cell phone use to all other variables.\u0000Results: There were large, significant effect sizes (r ≥ -0.58, p ≤ 0.04) for negative correlations between cellphone use and vigorous and total physical activity. There was also a moderate effect size (r = -0.39; r = 0.46) for a negative relationship between cellphone use and mild physical activity and a positive correlation between cellphone use and anxiety, respectively. Cellphone use was not related to the remaining variables. \u0000Conclusions: In this preliminary study of high school students, greater cellphone use was associated with greater anxiety, which supports prior research in adults. However, unlike research reporting a lack of a relationship in adults, greater cellphone use was associated with lower physical activity in high schoolers.","PeriodicalId":74674,"journal":{"name":"Research Directs in health sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42276368","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 assessed the validity of a novel, low-cost wearable physical activity monitor (Movband 3) relative to established measures. Methods: Participants (N = 19) completed four treadmill stages (1.5, 3.0, 4.0, 6.0 MPH) while wearing the Movband 3 and the validated Actigraph GT1M monitor. Oxygen consumption (VO2 ml/kg/min) and heart rate (beats/min) were recorded. The relationship between Movband data and established measures was assessed via Pearson’s correlations. Tests of agreement were performed for actual and Movband miles traveled. Results: There were large, positive, significant (p < 0.001) effect sizes for the associations between Movband counts and Actigraph counts (r = 0.72), VO2 (r = 0.59), and heart rate (r = 0.63). There was also a large, positive, significant (p < 0.001) association between actual and Movband miles (r = 0.97). However, the difference (Δ) between Movband and actual miles was greater than a null hypothesis of zero (∆ = 0.77 ± 0.45 miles or 31.8%, t = 7.4, p < 0.001).

Baseline and posttest SBP and DBP measurements were obtained. Participants resistance trained and logged their sessions in a smartphone application three times per week for 8 weeks. They also measured their blood pressure weekly with a home kit. Changes in SBP and DBP between the three groups were tested using a mixed model 3 x 2 ANOVA analysis with follow-up post-hocs as necessary.Results: There was no significant interaction between rest interval group and time for SBP or DBP. For SBP, there was a significant main effect for time, p<0.001 (pre: 115 mmHg vs. post: 108 mmHg).Conclusions: SBP and DBP were not significantly influenced by rest interval length over time. The resistance training program had no effect on DBP but significantly decreased SBP regardless of rest interval.

Medium and high protein intakes positively influenced body composition.
