Summary: The present study aimed to investigate the effect of cold water immersion (CWI) on the recovery of neuromuscular fatigue following simulated soccer match-play. The results showed that CWI reduced both central and peripheral components of fatigue, leading to earlier full recovery of the neuromuscular function and performance indices. Therefore, CWI might be an interesting recovery strategy for soccer players.

Summary: Two types of adhesive bonded joints with different base materials were tested for fatigue strength and fracture morphology after water immersion. The fatigue strength of the joints with JIS SPCC590Y adherends significantly decreased, while the joints with JIS SUS316 adherends showed a slight decrease in fatigue strength and an increase in cohesive failure rate. Oxides were generated at the bonding interface in structures bonded to JIS SPCC590Y, leading to rapid decrease in bonded interface strength. In contrast, for adherends with excellent corrosion resistance, interfacial failure did not occur but cohesive failure did, resulting in high static and fatigue strength.

Summary: Cold water immersion (CWI) is a popular method for reducing post-exercise muscle stiffness and fatigue, as well as promoting recovery. However, there are conflicting opinions regarding its effectiveness. This systematic review and meta-analysis examined the effects of CWI on fatigue recovery and exercise performance. The results showed that CWI significantly reduced subjective characteristics such as muscle soreness and perceived exertion, as well as objective indicators like countermovement jump and creatine kinase levels. However, CWI had no effect on C-reactive protein and IL-6 levels. Subgroup analysis indicated that different CWI sites and water temperatures did not influence post-exercise fatigue recovery. Overall, athletes are recommended to use CWI immediately after exercise to reduce muscle soreness and accelerate fatigue recovery.

Summary: This study investigated the impact of moderate muscle cooling on muscle force and contractility in both unfatigued and fatigued state. The results showed that both single and intermittent/prolonged cold-water immersions had significant effects on muscle contraction. However, the effects were more pronounced with the intermittent/prolonged condition during the fatiguing protocol.

Summary: The effectiveness of post-exercise cooling and heating interventions remains uncertain. Cooling has positive effects on fatigue resistance in hot conditions and recovery of maximal strength in the early phase of recovery, but chronic exposure impairs strength adaptations and fatigue resistance. Limited data suggest promise for heating interventions in endurance and sprint exercises.

Summary: This article presents the development of a digital twin model for the thigh portion undergoing various thermal treatments. Two scenarios, cold water immersion (CWI) and whole body cryotherapy (WBC), are investigated and the numerical results are validated against experimental measurements. The use of real geometry on a first subject demonstrates the heterogeneity of the temperature field and the importance of accurate geometry. A second subject with thicker adipose tissue highlights the impact of the subject's actual morphology on treatment validity and the need for real geometry to optimize cold modalities and develop personalized treatments.

Summary: Whole-body cold water immersion is considered the gold standard treatment for exertional heat stroke, but the guidelines for treatment are being applied to women without validation. Recent evidence suggests that women cool faster than men during cold water immersion, raising concerns of overcooling if the present guidelines are followed.

Summary: An increasing number of people are using cold showers or outdoor swimming for fitness and health benefits. Cold-water immersion can lead to elevated positive emotions and reduced negative emotional state, and these mood changes are associated with changes in brain connectivity. Short-term whole-body cold-water immersion may have integrative effects on brain functioning, contributing to improved mood.

Summary: In this study, the regular application of cold water immersion or hot water immersion following resistance exercise did not attenuate (nor promote) increases in lean muscle mass in athletes. However, post-resistance exercise in the control group or cold water immersion group resulted in trivial increases in squat jump height compared to the hot water immersion group.

Summary: This study compared the effects of cold-water immersion (CWI) with other common recovery modalities on recovery from acute strenuous exercise. It found that CWI was superior in reducing muscle soreness and similar to other methods for recovering muscular power and flexibility. CWI was more effective than active recovery, contrast water therapy, and warm-water immersion for most recovery outcomes.

Summary: This study aimed to investigate the association between childhood measures of sleep health and epigenetic age acceleration in late adolescence. The results showed no evidence for a relationship between parent-reported sleep trajectories and epigenetic age acceleration. However, there was a positive cross-sectional relationship between self-reported sleep problems and intrinsic epigenetic age acceleration, which was attenuated after controlling for depressive symptom score. This finding may suggest that adolescents with higher depressive symptoms have greater overtiredness and intrinsic epigenetic age acceleration. Mental health should be considered as a potential confounding variable in future research on sleep and epigenetic age acceleration, especially when using subjective sleep measures.

Summary: This study aimed to develop age-specific reference intervals for physical performance test outcomes relevant to male youth Middle Eastern football players. Using mixed-longitudinal data from 441 male youth outfield football players, the study estimated age-specific reference centiles for sprinting, jump height, and aerobic speed variables. The results showed that the physical performance test scores increased nonlinearly with advancing chronological age, reaching a plateau after 16 years for sprinting and jump measures. The median score for aerobic speed increased substantially until around 14.5 years and then flattened off towards older ages.

Summary: As lifestyles have changed to prioritize nighttime activities, daytime sleepiness has become a common issue among Japanese university students, with an overall prevalence of 57%. Factors associated with excessive daytime sleepiness (EDS) include female sex, exercise habits, long commuting times, later wake-up times, and shorter sleep duration. Interventions, such as educational programs promoting strategies to increase sleep duration and delay wake-up time, should be considered to reduce the risk of EDS among university students.

Summary: This study identifies early-life factors predisposing young adults to obstructive sleep apnoea (OSA). The findings show that various factors related to poor maternal metabolic health, high-risk pregnancy, and difficult perinatal events predict OSA in young adults. These findings are important for the early identification and management of at-risk individuals, as well as for improving maternal health to reduce the likelihood of young adults developing OSA.
