Summary: High-intensity interval training (HIIT) is a common method used to improve athletic performance, aid in rehabilitation, and prevent diseases. However, research suggests that exceeding a certain limit of HIIT might have detrimental effects on metabolic health.

Summary: The health benefits of physical activity depend on the frequency, intensity, duration, and type of exercise. Intensity is a crucial element and should be prescribed based on individual boundaries. Regular reassessment and adjustment are necessary to maintain physical activity in the moderate to vigorous intensity domains.

Summary: This study compared the acute physiological, perceptual, and enjoyment responses between bodyweight high-intensity interval exercise (BW-HIIE) and treadmill running high-intensity interval exercise (RUN-HIIE). The results showed that BW-HIIE elicited higher oxygen consumption, blood lactate, heart rate, and rating of perceived exertion compared to RUN-HIIE, while the physical activity enjoyment was similar between the two exercises.

Summary: This systematic review and meta-analysis aimed to compare the effects of high-intensity interval exercise (HIIE) with different recovery modes versus moderate intensity continuous exercise (MICE) on cardiac troponin (cTn) elevation. The results showed no significant difference between HIIE and MICE in the elevation of cardiac troponin T (cTnT). However, HIIE with passive recovery elicited more release of cardiac troponin T (cTnT) than MICE.

Summary: A scoping review was conducted to investigate the acute physiological response to HIFT-based exercise. The review found that markers of intensity were consistently assessed, supporting the idea that HIFT workouts are performed at high-intensity. However, the inclusion of other measures has been inconsistent, limiting the ability to draw generalized conclusions.

Summary: This study evaluated the validity of prescribing exercise intensity using wrist-worn devices. The results showed that heart rates measured by the Apple Watch Series 6 and Garmin Forerunner 945 can be used to accurately estimate exercise intensity. Further research is needed to confirm these findings in other populations.

Summary: This study explored the applicability and exercise intensity of Xiangya Hospital Circuit Training (X-CircuiT) in different age groups. The results showed that X-CircuiT can be adjusted according to age and maximum exercise capacity, making it suitable for moderate-intensity exercise for sedentary middle-aged and older adults, and low-intensity exercise for young people.

Summary: Exercise is a strong reinforcer for both animals and humans, with HIIT being shown to have a higher reinforcing value compared to MIAE. Inactive individuals may find HIIT more rewarding and may be more likely to adopt and maintain an exercise program involving HIIT rather than MIAE. Further research is needed to understand how to enhance the reinforcing value of exercise to encourage sedentary individuals to be more active.

Summary: Low-volume HIIT, involving short bouts of high-intensity exercise, has shown to provide similar, or even greater, health benefits compared to traditional aerobic exercises. The improvements seen in cardiorespiratory health, glucose control, and cardiac function may be attributed to enhanced mitochondrial function and insulin sensitivity. Additionally, low-volume HIIT is well-tolerated and safe for adults, with high exercise adherence rates and minimal adverse effects reported.

Summary: Health clubs are important for exercising, but they struggle to retain participants in the long term. This study examines the relationship between intensity traits, current training intensity, and subjective vitality, habit, and exercise frequency. The results suggest that having consistency between intensity traits and current training intensity leads to better outcomes in terms of vitality, habit, and exercise frequency.

Summary: The study found that both high-intensity interval exercise (HIIE) and moderate-intensity continuous exercise (MICE) have positive effects on executive function and oculomotor performance in late middle-aged and older adults. Both exercise modes were able to reduce reaction times in performance tasks, while HIIE showed a more significant improvement in oculomotor control compared to MICE.

Summary: The recent global COVID-19 pandemic has led to a high demand for an effective virus inactivation method. This study evaluated the potential and mechanism of human coronavirus inactivation using atmospheric pressure plasma (APP) technology. The results showed that a 30-second exposure to APP significantly reduced the HCoV-229E titers, indicating strong virus-inactivation efficacy. It was found that the production of reactive oxygen and nitrogen species (RONS), particularly O-2 (center dot-), played a crucial role in the inactivation process. These findings provide new insights into a more efficient method for inactivating human coronaviruses using APPs.

Summary: Environmental carbon dioxide (CO2) could have an impact on mental and physiological activities, but its effect on daytime sleepiness is still debated. In this study, the researchers used a combination of classical frequentist and Bayesian statistical methods to analyze the effect of CO2 exposure on daytime sleepiness and EEG signals. The results showed that daytime sleepiness was significantly influenced by exposure time, but not by the CO2 condition according to classical statistics. However, the Bayesian paired t-test suggested that CO2 exposure at a moderately high concentration could induce daytime sleepiness at a specific time point. EEG signals were significantly affected by short exposure to a high concentration of CO2, but exposure time did not have a significant impact. The Bayesian analysis of EEG results was generally consistent with the classical statistics, but showed different credible levels in the Bayes' factor. The study suggests that EEG may not be suitable for detecting objective sleepiness induced by CO2 exposure due to its high sensitivity to environmental CO2 concentration. This research provides valuable insights for reconsidering the use of EEG as an indicator of objective sleepiness.

Summary: The study examines the effects of a 6-week reactive agility training program using light-based stimuli on the physiological and cognitive abilities of car racing drivers. The results show that the training program improves participants' cognitive performance, reaction time, peak heart rate, ventilation, and relative maximal oxygen consumption. It also suggests that the program has the potential to contribute to the physical and mental performance of car racing drivers.

Summary: The skeletal muscle fiber type can be changed during muscle regeneration after cardiotoxin injection, but the mechanism of fiber type transition is still unclear. Previous studies have shown that CTX-induced muscle damage leads to temporary hypoxia, suggesting the involvement of HIF-1a in the transition. This study demonstrates that CTX-induced muscle injury causes transient ischemia and stabilizes HIF-1a, leading to an increase in oxidative muscle fibers through the calcineurin/NFATc1 signaling pathway.

Summary: Skeletal muscle maintenance relies on muscle stem cells that provide myoblasts for muscle regeneration and growth. Proteasome dysfunction in skeletal muscle impairs muscle growth and development. Aminopeptidase inhibition affects the proliferation and differentiation ability of C2C12 myoblasts. Knockdown of different aminopeptidases in C2C12 myoblasts results in defective myogenic differentiation, except for leucine aminopeptidase 3 (LAP3) which promotes myogenic differentiation. Knockdown of LAP3 inhibits proteasomal proteolysis, decreases branched-chain amino acid levels, and enhances mTORC2-mediated AKT phosphorylation to promote myogenic differentiation through increased expression of myogenin.
