Correlation relationship between biomechanical links and the result of competitive exercises in powerlifting

Abstract

Powerlifting is a strength sport, in which competitions are held based on the sum of exercises - squats, bench presses and dead lift. Competition in high performance sports in general and in powerlifting in particular prompts coaches and athletes to search for optimal training programs. Anthropometric indicators of athletes can affect the result in powerlifting in several ways. For example, athletes with higher muscle mass and a lower percentage of body fat have a strength advantage within their category over athletes with a lower level of muscle mass development. Another way is the ratio of the length of the body links. The purpose of the article was to study the influence of the length of body links in qualified and highly qualified powerlifters on performance in competitive exercises. The research was carried out on the basis of the Kharkiv State Academy of Physical Culture. A total of 23 powerlifting athletes took part in the study. The athletes were divided into groups of qualified and highly qualified powerlifters. Statistically significant differences were found in thigh length (t=2.32, p<0.05), leg length (t=2.29, p<0.05), Brugsch index (t=2.40, p< 0.05). A statistically significant inverse relationship was found between standing body length indicators and squats (r=-0.42, p<0.05), deadlift (r=-0.43, p<0.05) and sum (r =-0.42, p<0.05). The length of the thigh and lower leg has an inverse statistically significant relationship with the squat, deadlift, and total sum. The length of the shoulder and forearm are correlated with the bench press (r=0.43, p<0.05) and (r=0.41, p<0.05), respectively. The Brugsch index is statistically significantly correlated with squats (r=0.43, p<0.05), bench press (r=0.54, p<0.01), deadlifts (r=0.44, p<0.05 ), and the amount of sum (r=0.46, p<0.05).
