Summary: The study found that concurrent training (CT) was effective for increasing cardiorespiratory fitness and muscular strength in middle-aged to older adults compared to aerobic training (AT) or resistance training (RT) alone. CT should be considered as a viable strategy for improving CRF and muscular strength with aging, without negative effects on these outcomes compared to AT or RT alone.

Summary: This study investigated the muscular and cardiorespiratory adaptations of two water-based training programs in older women. The results showed that both water-based aerobic training and water-based combined training can improve maximal strength and oxygen uptake. However, only water-based training programs are capable of improving the maximal strength of the lower limbs.

Summary: The study aimed to develop a simple submaximal walk test protocol and equation to predict maximal oxygen consumption using heart rate responses. The equations developed showed significant correlations between heart rate variables and VO(2)max, particularly at 120 steps per minute cadence. This suggests that the 3MWT developed in the study is a promising and accurate submaximal exercise protocol for predicting VO(2)max in healthy adults.

Summary: Moderate-intensity aerobic exercise training is crucial for stroke recovery and reducing cardiometabolic risk factors. This study compared the effects of task-oriented circuit training (IFT) to constant-load ergometer-type exercise (CET) on cardiovascular fitness and metabolic profiles in chronic stroke survivors. Despite similar workload sustainability, CET showed greater improvements in maximal oxygen uptake compared to IFT, indicating the need for further research on the dose-response effects of task-oriented circuit training protocols in stroke recovery.

Summary: This study aimed to evaluate the relationship between energy availability (EA) and macronutrient intake with performance, anthropometric characteristics, blood markers, training volume, and risk of low energy availability (LEA) in young female cross-country skiers. The results showed that body fat percentage (F%) and training volume were the most important factors explaining performance. Additionally, lower carbohydrate intake and EA increased the risk of LEA. These findings highlight the importance of adequate nutritional intake for supporting performance and overall health.

Summary: The present study examined the association of serum 25(OH)D levels with physical performance outcomes and serum levels of anabolic hormones in young men. The results showed a positive association between serum 25(OH)D levels and both aerobic and muscular fitness. Participants with sufficient levels of vitamin D also had higher levels of testosterone. Maintaining a sufficient serum 25(OH)D level may have beneficial effects on physical performance and anabolic state in young men.

Summary: This study examined the influence of endurance training on maximal oxygen uptake (VO(2)max), muscle power, and sports-related performance in cross-country skiers. The results showed that endurance training significantly improved ski-specific performance, but had minimal impact on VO(2)max. Therefore, the improvement observed may reflect better upper-body performance, rather than changes in VO(2)max.

Summary: Sensorimotor training and strength training can improve balance control. Little is known about how repeated balance perturbation training affects balance performance and its neural mechanisms. This study found that balance perturbation training led to less body sway and a potential increase in spinal-level involvement, indicating possible movement automaticity after perturbation training.

Summary: The present study examined the changes in physiological, mental, and physical performance during a 20-day winter military training course and the subsequent 10-day recovery period. The study included 58 male soldiers who underwent measurements of body composition, serum biomarker levels, and performance tests. The results showed significant declines in body and fat mass, physical performance variables, testosterone, and IGF-1 concentrations, while sex hormone-binding globulin, creatine kinase, and C-reactive protein values increased. Although some physical performance variables returned to baseline after the recovery period, explosive force production in the upper and lower bodies remained unrecovered.

Summary: This study investigated spinal excitability during the transcranial magnetic stimulation (TMS) silent period (SP) at different time delays in m.rectus femoris. The results showed that reduced spinal excitability was extended during 50% and 75% of maximum voluntary contraction (MVC). In the future, paired TMS-lumbar stimulation (LS) could be a valuable method for studying changes in spinal excitability during SP and testing various neurophysiological phenomena.
