Directed asymmetric power action an effectivization factor in sprint coaching

Abstract

Abstract: This study offers training methodology for sprinters. A principle of directed asymmetric power action (DAPA) on lower limbs in natural conditions of high-speed running is at the core of the methodology. During running workouts we use light weight on a non-dominant leg. An application of the above-mentioned methodology for an experimental group of sprinters in Siberian Federal University during 11 weeks has contributed to modification of ritmo-structural (RS) running characteristics, “speed barrier” overcoming and improvement of seasonal rates on 50 m distance: time and stride quantity decreasing by 0.4 s and 1.3 units, stride rate and stride length increasing by 0.04 Hz and 0.09 m respectively.
