Brief Summary

Speed is one of the most important physical capacities for many sports, especially those that include speed and power as a major element, and plays a major role on performance. Running speed improvement is one of the most basic components of a sprint and power athlete's training program. One of the most commonly used strategies to improve the initial acceleration phase, is resisted sprint training. Sprinting is performed through the stretch-shortening cycle and highly includes the component of eccentric muscle contraction, which can lead to exercise induced muscle damage (EIMD). This phenomenon includes symptoms such as plasma CK elevation, delayed onset of muscle soreness, reduction in force production and a reduction in agility and speed. However, despite the fact that sprint training can cause EIMD symptoms and a performance reduction the following days, research evidence on the recovery kinetics after sprint training are scarce. However, such information is critical for coaches and athletes, in order to effectively design a training program and incorporate the training components in the training microcycle, to avoid injuries and maximize performance. The aim of the present study is to examine the recovery kinetics of EIMD indices, muscle performance and neuromuscular fatigue, after different sprint training protocols.
