Muscle strength is often measured through the performance of a one-repetition maximum (1RM).


The aim of this study was to investigate lactate recovery kinetics after high-intensity exercises.

Sprint interval training (SIT) provides a potent stimulus for improving maximal aerobic capacity ([Formula: see text]), which is among the strongest markers for future cardiovascular health and premature mortality.

Subacromial impingement syndrome (SIS) has been reported as an etiological source of shoulder pain among weight-training (WT) participants; however, a paucity of evidence exists to describe intrinsic risk factors.

In strength training (ST), muscle activity is often analyzed by surface electromyography (EMG) and muscle damage through indirect markers, such as plasma concentrations of creatine kinase (CK) after exercise. However, there is little information about the influence of the strength exercises order on these parameters.

The present study aimed to investigate the influence of subjects’ strength level on both the ability to maintain power output performance and the physiological and perceived exertion responses during a power training session when different rest intervals (RI) are used.

Program variables such as training intensity, volume, and rest interval length are known to elicit distinct hormonal, metabolic, and physical responses.
