Neuromuscular electrical stimulation (NMES) has been used to increase muscle strength and physical function. However, NMES induces rapid fatigue, limiting its application. To date, the effect of quadriceps femoris (QF) muscle length by knee and hip joint manipulation on NMES-induced contraction fatigability is not clear. We aimed to quantify the ef...

In the context of academy soccer teams, coaches aim to develop players’ physical qualities. Literature demonstrates that the most demanding sessions (MDS), supposed to enhance players’ development, are usually performed four and three days before match day (MD-4 and MD-3) during traditional (TRAD) soccer periodization. However, other sports impleme...

Post-activation potentiation (PAP) is a well-described phenomenon with a short half-life (~28 s) that enhances muscle force production at submaximal levels of calcium saturation (i.e., submaximal levels of muscle activation). It has been largely explained by an increased myosin light chain phosphorylation occurring in type II muscle fibers, and its...
