APPARATUS FOR DETERMINING SPORTIVE AND HEALTH-IMPROVEMENT RACE HABITS QUALITY

摘要

FIELD: sports equipment. SUBSTANCE: apparatus has sound-emitting member to be fastened to the body of runner. Sound-emitting member is formed as metal pendulum fastened in plastic box, with rod being used as pendulum. In the process of racing, spring-biased metal load is movable along rod as a result of interaction between body of runner and support. Sound warning indicative of excessive values of vertical and horizontal reactions of support is generated, when load comes into collision with shaft limiter. Plastic box incorporating the pendulum serves as resonator; it increases loudness volume of sound and makes it more distinct to facilitate perceptibility of sound by runner. EFFECT: increased efficiency and enhanced reliability in operation. 1 dwg
