Effects of Resistance Training Volume on Physical Function, Lean Body Mass and Lower-Body Muscle Hypertrophy and Strength in Older Adults: A Systematic Review and Network Meta-analysis of 151 Randomised Trials

Radaelli, R., Rech, A., Molinari, T. et al.  Sports Med 55, 167–192 (2025). Background The optimal prescription and precise recommendations of resistance training volume for older adults is unclear in the current literature. In addition, the interactions between resistance training volume and program duration as well as physical health status remain to be determined when assessing physical function, muscle size and hypertrophy …

From Tissue to System: What Constitutes an Appropriate Response to Loading?

Gabbett, T. J. & Oetter, E. Sports Med. 55, 17–35 (2025). Optimal loading involves the prescription of an exercise stimulus that promotes positive tissue adaptation, restoring function in patients undergoing rehabilitation and improving performance in healthy athletes. Implicit in optimal loading is the need to monitor the response to load, but what constitutes a normal response to loading? And does …

The Time Course of Injury Risk After Return-to-Play in Professional Football (Soccer)

Zhang, G., Brink, M., aus der Fünten, K. et al.  Sports Med 55, 193–201 (2025). Injury risk in professional football (soccer) is increased in the weeks following return-to-play (RTP). However, the time course of injury risk after RTP (the hazard curve) as well as its influencing factors are largely unknown. This knowledge gap, which is arguably due to the volatility of instantaneous …

Evidence of Left Ventricular Cardiac Remodeling After 6 Weeks of Sprint Interval Training

Eriksson LM, Hedman K, Åström‐Aneq M, Nylander E, Bouma K, Mandić M, Gustafsson T, Rullman E. Scandinavian Journal of Medicine & Science in Sports. 2024 Dec;34(12):e70007. Sprint interval training (SIT) leads to similar improvements in maximal oxygen uptake (V̇O2max) and maximal cardiac output as previously reported for traditional endurance training, but the exercise-induced effects on cardiac remodeling are still largely …

Optimal Frequency of Interrupting Prolonged Sitting for Cardiometabolic Health: A Systematic Review and Meta-Analysis of Randomized Crossover Trials

Yin, M., et al. (2024), Scand J Med Sci Sports, 34: e14769 Increasing evidence highlights the efficacy of interruptions in prolonged sitting (i.e., activity/sedentary breaks) for improving cardiometabolic health, but precise conclusions and recommendations regarding the optimal interruption frequency remain poorly defined. This systematic review and meta-analysis aimed to directly compare the effect of different frequencies of interrupting prolonged sitting …
