Summary: This study compared the effects of weightlifting and plyometric training on physical performance in elite male junior table tennis players. The results showed that after 8 weeks of training, both weightlifting and plyometric training groups significantly improved their performances. However, the weightlifting group showed larger improvements and effect sizes compared to the plyometric group. Therefore, weightlifting training may be more effective in improving neuromuscular performance in table tennis players.

Summary: This study compared the effects of single High-Intensity Interval Training (HIIT) and combining HIIT with an incongruent Stroop task on mental and physical fatigue indicators. The results showed that combining the Stroop task with HIIT increased mental fatigue and perceived exertion, but did not affect external (speed) and internal (heart rate) factors. This suggests that mental fatigue can increase the subjective perception of physical exertion, but does not decrease the physical workload during HIIT for tennis players.

Summary: This study investigated whether walking with blood flow restriction (BFR) can increase cardio-respiratory demands and serve as an alternative to jogging. The results showed that moderate-intensity BFR walking induced the highest cardio-respiratory and perceptual responses compared to other walking sessions. However, jogging elicited higher cardio-respiratory measures than moderate-intensity BFR walking, except for systolic blood pressure. Perceptual measures were higher during moderate-intensity BFR walking compared to jogging. Overall, BFR walking does not seem to provide an equivalent exercise modality for unrestricted jogging in physically active adults.

Summary: The aim of this study was to investigate the acute performance and physiological responses to manipulating the exercise-to-rest ratio (E:R) during repeated-sprint hypoxic training (RSH) in hot conditions. The results showed that E:R-1:4 training increased mechanical power output and core temperature compared to E:R-1:2 training. Additionally, the two protocols had different effects on measures of muscle oxygenation. These findings provide a strong foundation for future mechanistic investigation into the effects of E:R manipulation during RSH in a hot environment.

Summary: Muscle glucose transport activity increases with exercise by translocating glucose transporters to the plasma membrane. This process remains intact in insulin resistant individuals and those with type 2 diabetes mellitus (T2DM). Exercise training is important for managing T2DM, but acute systemic glucose responses are often increased post-exercise despite increased glucose uptake. This review aims to summarize the knowledge on insulin action and glucose uptake in skeletal muscle and discuss the discrepancies between systemic and localized glucose responses. It also explores the potential of hypoxic training to enhance the effects of exercise on glucose regulation.

Summary: This study compared the psychophysiological responses of repeated cycling sprints to exhaustion with a short exercise-to-rest ratio (1:6) between different effort durations and inspired oxygen fractions. The results showed that the number of sprints and peak power output decreased, while blood lactate increased during the 5:30 exercise compared to longer durations. However, oxygen fractions and exercise-related sensation did not affect blood lactate levels. Muscle deoxyhemoglobin increased and total hemoglobin decreased with increasing sprint duration. The study concluded that oxygen levels did not modify the psychophysiological responses during repeated-sprint exercise with a short exercise-to-rest ratio, and sprint duration was the primary factor affecting performance and muscle oxygenation.

Summary: The study aimed to compare total hemoglobin mass (tHb(mass)) and blood volume (BV) among swimmers of different competitive levels and distances. The results showed that there were no differences in tHb(mass) and BV values between swimmers of different levels and distances. These values also did not correlate with FINA points. This suggests that hematological characteristics may have a lesser impact on swimming performance.

Summary: Caregivers of persons with DoC experience high levels of perceived burden, which is associated with adverse physical, emotional, psychosocial, and financial outcomes and is directly tied to expressed needs for information and support. Providing individualized education and training at each phase of recovery can enhance effective communication between providers and caregivers, helping to increase caregiver proficiency in managing their loved one's care while also helping to mitigate the challenges associated with perceived burden. This may subsequently increase the rate of community discharge among persons with DoC, potentially translating to a reduction in the long-term costs of care for this population.

Summary: Acute disorders of consciousness refer to impairments in arousal and awareness that occur within 28 days of an initial injury, which can be caused by various insults. Thorough evaluations, including assessments of consciousness level, brainstem reflexes, and motor responses, are important. Laboratory tests, imaging, and electrophysiology testing are needed for the evaluation of acute disorders of consciousness. Prognostication in this phase should be done cautiously, with open and frequent communication with families, considering the significant multidimensional uncertainty.
