Excessive content of adipose tissue is directly associated with the incidence of such civilization-related diseases as coronary heart disease, hypercholesterolemia, arterial hypertension, diabetes, pulmonary disorders, and osteoarthritis [1]. As an overweight-associated rise in mortality rates has been observed [2], community awareness of the positive consequences of maintaining proper values of Body Mass Index (BMI) and fat mass (FM) has been increasingly promoted. In most individuals, BMI constitutes a reliable indicator of overweight and obesity.

However, for all persons physical activity is the recommended way of maintaining the normal body mass [1,2,4]. In sumo, one wrestler attempts to force the opponent out of a circular ring or knock him down to the ground with an aid of specific throws, shoves, and body hits [5,6].

Therefore, athletes with higher body mass are more effective during the match and are harder to
