MAXIMAL VELOCITY SPRINT MECHANICS

Sprinting is a complex task that places a high neuromuscular demand on the performer and requires high levels of coordinated movement and appropriate sequencing of muscle activations to perform at peak levels. This paper will examine maximal velocity sprint mechanics with particular focus on the primary factors affecting performance, the mechanics associated with those factors, and the causal relationships that occur as a result of optimal sprinting mechanics.

RELAXATION AND SPRINTING IN TEAM SPORTS

Coaches and athletes are well aware that the absence of efficient, tension- free muscular movement produces more rapid fatigue, poor performance, and increases the incidence of injuries. Executing short sprints in team sports also requires very efficient muscular coordination and relaxed movement patterns. During relaxed movement, less pliant tense muscles restrict range of motion and keep athletes from reaching their maximum mph speed.

RELATIONSHIPS BETWEEN GROUND REACTION FORCE IMPULSE AND KINEMATICS OF SPRINT-RUNNING ACCELERATION

The literature contains some hypotheses regarding the most favorable ground reaction force (GRF) for sprint running and how it might be achieved. This study tested the relevance of these hypotheses to the acceleration phase of a sprint, using GRF impulse as the GRF variable of interest. Thirty-six athletes performed maximal-effort sprints from which video and GRF data were collected at the 16-m mark. Associations between GRF impulse (expressed relative to body mass) and various kinematic measures were explored with simple and multiple linear regressions and paired t-tests.

THE 100-METER DASH:SUMMARY TRAINING RECOMMENDATIONS FOR START TO FINISH

Developing a complete training program for the 100-meter dash is a much more complicated task than meets the eye. At first glance, it appears that it is merely an all-out sprint as athletes attempt to reach maximum speed as fast as possible and maintain that speed throughout the race. In reality, the race involves five different phases, each requiring special training techniques.
