Yoga has been shown to reduce stress and to provide health benefits for a number of stress-related disorders. However, the effects and mechanism of an acute bout of yoga practice on relieving stress remain unclear. The aim of this study was to examine the effect of a single bout of yoga on heart rate (HR) and heart rate variability (HRV) response to and recovery from mental stress. This study was conducted with a randomised, counterbalanced, crossover design. A total of 44 participants (mean age 24.58 ± 3.84) completed two conditions (yoga and video watching (VW)) in a randomly assigned order. After each condition, participants underwent a Stroop task and mental arithmetic task. HR and HRV, measured via electrocardiogram, were recorded and analyzed at rest, during each condition, and during the stress and recovery periods. HR was significantly lower during the yoga condition as compared to that during the VW condition. There was no significant difference in HRV observed between the conditions. During both mental stress and recovery periods, there was no significant difference in HR or HRV responses between the yoga and VW conditions. These findings suggested that an acute bout of yoga practice was not superior to quiet sitting in reducing HR and HRV reactivity to and recovery from mental stress. Future studies may consider investigating individuals with exaggerated cardiovascular reactivity to further examine the potential reactivity-lowering effect of yoga. [ABSTRACT FROM AUTHOR]

Engineers in the semiconductor industry frequently experience recurrent low back pain (LBP) due to prolonged, repetitive work postures. The operation of machinery in this industry requires a high level of muscle endurance. Dynamic taping can help reduce stress on joints and soft tissues during movement.This study investigated the effect of dynamic taping in workers with recurrent LBP, focusing on pain levels, muscle strength, work-related endurance, and fear avoidance behaviors.This crossover study recruited 28 engineers with repetitive LBP from the semiconductor industry. Each participant underwent two interventions: dynamic taping and no taping. Participants completed a maximal isometric back extensor strength test, three muscle endurance tests (Biering–Sorensen, kneeling forward lean, and repetitive lifting), and two LBP questionnaires (visual analog scale [VAS] and Fear Avoidance Belief Questionnaire 2 [FABQ2]) in each scenario. MicroFET2 was used to assess back extensor strength. Electromyography (EMG) was performed to determine peak or mean values and median frequencies of the erector spinae muscle before and after endurance tests. Total endurance test durations and posttest VAS scores were recorded. FABQ2 scores were evaluated again 3 days after taping.The results of the paired t test revealed that dynamic taping significantly improved performance in the kneeling forward lean test (p < 0.01) and increased maximum isometric strength (p < 0.01). Furthermore, dynamic taping reduced VAS scores after three endurance tests (all p < 0.01) and FABQ2 score (p = 0.03). Two-way repeated measures analysis of variance revealed significant time effects in the Biering–Sorensen on average EMG activation (p < 0.01) and median frequencies during fatigue monitoring (p < 0.01). Significant time effects were also found in the kneeling forward lean test on median frequencies (p < 0.01). In addition, significant interaction effects were found in the Biering–Sorensen test on average EMG activation (p < 0.01) and in the kneeling forward lean test on median frequencies (p < 0.01). Compared with the no-taping group, the taping group exhibited a more significant decrease in erector spinae muscle activity and maintained median frequencies during fatigue tests.The use of dynamic tape significantly enhanced maximum isometric strength, improved performance in work-related endurance tests without increasing muscle activity, and reduced FABQ2 scores among semiconductor engineers with recurrent LBP.

Exergame has become widely popular and offers great levels of cognitive demands, thus may facilitate cognitive benefits. In addition, researchers have proposed that cardiac autonomic function, assessed via heart rate variability (HRV), is associated with cognitive executive function. However, few exergame training studies have investigated this relationship. This study aimed to investigate the effects of 10-week exergame training on executive function and HRV in middle-aged and older adults. Ninety-one participants were randomly assigned to either an exergame training group (63.73 ± 4.48 years) or a control group (62.46 ± 4.77 years). The training program was 50 min per session, twice per week for 10 weeks. The control group was instructed to maintain their usual lifestyle. All participants completed questionnaires and received assessments of executive functions and electrocardiography at baseline and postintervention. Results revealed significant group-by-time interaction effects for the three indices of the digit span test and the total initiation time of the Tower of London task with better postintervention performances achieved by the exergame group. The 6 min walk test also improved significantly in the exergame group but not in the control group. No significant change in HRV was observed for both groups. There were significant correlations between HRV and digit span test scores. Our results suggest that the 10-week exergame training program was effective in improving executive functions of working memory, inhibitory control, and planning ability as well as aerobic fitness in middle-aged and older adults. Moreover, HRV was associated with improved executive function., (© 2025 The Author(s). European Journal of Sport Science published by Wiley‐VCH GmbH on behalf of European College of Sport Science.)
