The Relation Between Different Phases of Sprint Run and Specific Strength Parameters of Lower Limbs

Luis Cunha, Department of Sport Science, Faculty of Human Movement, Technical University of Lisbon, Portugal

Purpose: Examine the relationship between different phases of a 100 meter sprint run (acceleration, max speed, deceleration) and results obtained from different tests (squat jumps, drop jumps, counter-movement jumps) to quantify the capability to produce force in isometric and stretch-shortening contraction modes, to discriminate between sprinters of different capacity.


Conclusions: No correlation was found between the different sprint phases and the various muscle force-producing tests.

IN PLAIN ENGLISH: Due to differences in body posture, joint angles, specific muscle contraction requirements, amount of resistances, etc., it is difficult to assess sprinting ability based on conventional non-specific tests done aside from the act of sprinting itself. The laws of specificity clearly state that comparing two seemingly similar activities can be flawed.
