Therefore, we tested whether wearing compressive pantyhose (CP) during the Ballet-specific aerobic fitness test (BAFT) would influence performance, recovery, physiological, and perceptual indicators. Additionally, this pilot study tested the feasibility of the research procedures and informed adjustments for the main study. Nine young classical ballerinas attended two sessions on different days: a) wearing CP (pressure of 20-30 mmHg) or b) wearing a placebo pantyhose ([PLA] no compression, containing an illusory effect) during the BAFT. We assessed heart rate (HR) and rating of perceived exertion (RPE) during the BAFT, perceived recovery (PRS), lower-limb delayed onset muscle soreness (DOMS) at Pre and 24 h Post, and standing heel-rise test performance at Pre, 30 min, and 24 h Post. No variables differed (p>0.05) between CP and PLA (e.g., HR mean over 5 BAFT phases: 178±14 bpm vs. 179±17 bpm, p=0.63; RPE 30 min post: 9.1±0.8 vs. 9.1±0.8 arbitrary units, p=0.94). However, wearing CP promoted attenuation in acute fatigue, while PLA showed a performance decrement (p<0.05) 30 min Post in the standing heel-rise test: CP 30.2±6.0 to 22.8±7.5 repetitions and PLA 36.2±11.7 to 22.9±6.3 repetitions. We conclude that CP may mitigate acute fatigue in the triceps <i>surae</i> muscle of amateur classical ballet dancers, making it relevant for their acute recovery, particularly in cases involving multiple daily performances.

While stretching aids recovery, its effects on autonomic balance are inconsistent. Yoga's combination of postures, breathing, and relaxation may further activate the parasympathetic system, making it a promising tool for sports recovery. This study employed a crossover design to examine the effects of yoga and stretching on post 30-min session of high-intensity interval training (HIIT) recovery in male athletes. Twenty athletes of Mae Fah Luang University (Age 20.95±0.99 years old, VO2max 42.53±4.79 ml/kg/min) were given recovery methods, 15-min stretching and 15-min yoga following HIIT. Heart rate, blood pressure, respiratory rate, and heart rate variability were evaluated immediately after HIIT, 5-min, 10- min, 15-min of the recovery period, and at 24-hour after recovery. A Two-way repeated-measures analysis of variance (ANOVA) was employed to examine the interaction effects between different methods and time of recovery. A significance level of 0.05 indicated a statistically significant difference. The findings indicated a statistically significant interaction between the group and time of heart rate variability and respiratory rate (p<0.05, effect size [ES] medium). Post-hoc analysis indicated that performing yoga showed a significantly lower respiratory rate at 5-min, 10-min, and 15-min compared to stretching (p<0.05, ES large). Yoga demonstrated a noteworthy enhancement in heart rate variability during the 5-min and 10-min recovery periods in comparison to stretching. In summary, this study provides empirical evidence supporting the efficacy of yoga as a post-exercise recovery strategy following high-intensity interval training. The role of breathing, rhythmic muscle contractions, and deep relaxation in yoga appears to facilitate the recovery phase more effectively than stretching alone. This suggests incorporating yoga as an active recovery regimen.</p>","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"18 6","pages":"79-91"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11798559/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143364455","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}

One program that has gained considerable popularity is the 12-3-30 treadmill workout (12-3-30), which involves walking at a 12% grade at 3 mph for 30 minutes. Despite widespread claims about its effectiveness in burning fat and calories, there is a lack of peer-reviewed scientific studies evaluating these claims. The present study investigated metabolic responses to 12-3-30 compared to self-paced treadmill running, with both sessions matched for total energy expenditure. Sixteen participants (7 female, 9 male) completed both sessions in a controlled laboratory setting, where metabolic data were collected using a metabolic analyzer. The measures recorded were completion time, total energy expenditure, energy expenditure rate, and substrate utilization (percentage of carbohydrate [%CHO] and fat [%FAT]). The results showed that, when matched for total energy expenditure, 12-3-30 had a significantly longer completion time, lower energy expenditure rate, higher %FAT, and lower %CHO than self-paced running. While 12-3-30 may be less time efficient than self-paced running for expending energy, it may be more advantageous for individuals aiming to increase fat utilization. The present study enhances our understanding of the metabolic demands associated with a trending fitness program and highlights the importance of scientifically evaluating such programs to provide evidence-based recommendations.</p>","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"18 6","pages":"56-64"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11798546/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143364505","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}

This study aimed to determine the correlations of electronic handgrip dynamometry derived strength, time to peak force generation, fatigability (22.40±10.12%), isometric control, and asymmetry with aerobic capacity in ambulatory young adults. We included 34 recreationally active ambulatory adults aged 23.76±3.57 years. Muscle function was assessed using electronic handgrip dynamometry. Aerobic capacity was examined using the six-minute wheelchair push test (1112.17±92.84ft).

Our findings show that electronic handgrip dynamometry derived fatigability is related to aerobic capacity in those who use manual wheelchairs. Given the relationships shown in the current study, electronic handgrip dynamometry has promise for assessing functional health in persons with disabilities, which has particular relevance for SCI, and could be used in clinical practice and physical medicine and rehabilitation (PM&R) as a tool to examine functional capacity in applicable populations.
