Summary: This study aimed to investigate the cardiorespiratory responses and adaptations of myocardial infarction (MI) patients during early outpatient cardiac rehabilitation (CR) when high-intensity interval training (HIIT) was prescribed using ratings of perceived exertion (RPE). The results showed that RPE-prescribed HIIT effectively increased exercise workload and oxygen uptake (VO2) without causing excessive perception of effort, heart rate, or blood pressure in MI patients during early outpatient CR.

Summary: This study investigated the effects of acute Judo training on performance and perceived fatigue among highly trained collegiate judo athletes. The results showed that neuromuscular fatigue was observed 24 hours after training. Loaded countermovement jump (CMJ) was found to be a better indicator of fatigue compared to unloaded CMJ. Therefore, when arranging high-intensity training, it is important to reduce the training volume appropriately to avoid fatigue accumulation and reduce the risk of sports injuries.

Summary: This study aimed to assess the validity of using the Borg CR-10 scale and velocity to predict muscle fatigue assessed by surface electromyography during single joint resistance exercises. The results showed that RPE is useful for assessing fatigue when resistance exercise is performed, but velocity changes may not accurately reflect muscle fatigue.

Summary: This study retrospectively analyzed 863 exercise test records to evaluate the relationship between ventilatory threshold (VT) and (V)over dotO(2peak), (V)over dotO(2)R, HRR, and RPE. The results showed significant variations in VT at different (V)over dotO(2peak) levels, and the VT%(V)over dotO(2)R followed a U-shaped curve. These findings contribute to the understanding of exercise prescription for individuals with different (V)over dotO(2peak) values.

Summary: This study found that using a-tDCS may improve the total volume of repetitions and perceived exertion in trained and untrained individuals during back squat exercises. However, peak power, velocity, and force did not show significant effects after a-tDCS. The untrained individuals experienced a higher rate of decrease in neuromuscular performance measurements compared to the trained individuals after the resistance exercise session.

Summary: This study examined the combined effects of competition area and judo-specific training type on physiological responses and perceived exertion in female judo athletes. The results demonstrated that varying training modality and area size may put stress on the cardiovascular system and increase anaerobic glycolysis solicitation.

Summary: The study found that arm cycling with electrical myostimulation induced more pronounced cardio-respiratory, metabolic, and perceived responses, especially during submaximal exercise. This form of exercise with stimulation may be beneficial for athletes in sports involving considerable upper body work output.

Summary: This meta-analysis aimed to examine the impact of exercise-induced dehydration (EID) on rating of perceived exertion (RPE) during endurance exercise. The results showed that there was a significant difference in RPE between different levels of EID within a body mass loss range of 0.5-3%. For every 1% increase in EID, RPE increased by 0.21 points. Factors such as humidity, ambient temperature, and aerobic capacity did not moderate the relationship between EID and RPE. Therefore, the effect of EID on RPE is not practically meaningful until a body mass loss of at least 3%.

Summary: The study aimed to estimate the global prevalence of meeting the WHO guidelines for aerobic and muscle-strengthening activities in populations aged >= 5 years. Only one out of five adolescents and adults met the recommended guidelines. Large-scale public health interventions are needed to reduce the burden of non-communicable diseases.

Summary: The World Health Organization (WHO) introduced a framework for healthy aging that focuses on functional ability instead of absence of disease. In a prospective cohort study, the link between mortality and respiratory diseases was investigated in almost half a million adults. The study found that higher levels of functional ability were associated with increased risk of respiratory disease mortality, highlighting the importance of the WHO's framework in improving geriatric care.

Summary: A common pre-season injury prevention assessment for football players is the hamstring-to-quadriceps (H:Q) strength ratio, which is calculated by peak torque. However, there is a debate about whether players with low pre-season H:Q ratios are more prone to in-season hamstring strain injuries (HSI). This study examined the pre-season H:Q ratios of professional male football players who sustained HSI during a particular season. The findings indicate that players who sustained in-season HSI had lower pre-season functional and conventional H:Q ratios compared to uninjured players, and this may be associated with higher levels of quadriceps concentric torque.

Summary: The present study examined the effects of acute caffeine supplementation on performance during resistance training alone or in combination with aerobic training. The results showed that caffeine supplementation was not effective in minimizing the interference effect of aerobic training on strength performance. However, it did improve strength performance during the first set of both aerobic and resistance training sessions.

Summary: The aim of this study was to determine the global incidence of type 1 diabetes mellitus (T1DM) in children and adolescents under 20 years of age from 2000 to 2022. The study included 126 studies from 55 countries and 18 regions. The incidence rate (IR) of T1DM from 2000 to 2022 was 14.07 per 100,000 person-years, with significant variations among different regions and an increase during the pandemic period.

Summary: This study assessed the differences in skeletal muscle energy metabolism between patients with long COVID syndrome (LCS) and healthy controls, and explored the mediating role of muscle power output in the relationship between COVID-19 and skeletal muscle energy metabolism. The results showed that patients with LCS had lower peak fat oxidation rates during exercise compared with healthy controls, potentially indicating impaired skeletal muscle function. Muscle power output predominantly mediated the relationship between peak fat oxidation and LCS.

Summary: This systematic review examined the effects of upper-body plyometric training (UBPT) on physical fitness in healthy youth and young adult participants. The results showed that UBPT improved maximal strength, medicine ball throw performance, sport-specific throwing performance, and upper limb muscle volume compared to control conditions. However, the certainty of evidence for these recommendations is low.
