Objective of the study was to identify differences between special strength fitness levels of armwrestlers of the middle (80-85 kg) and heavy (up to 110 kg and over 110 kg) weight categories.
Methods and structure of the study. Sampled for the study were 24 armwrestlers aged 18-42 years who were divided into 2 weight categories and 2 groups depending on their skill levels. Group I (n=12) included the athletes with the sports titles "World Class Master of Sport" and "Master of Sport of Russia". Group II (n=12) was made of the athletes with the sports qualifications of Class I athletes and Candidate Masters of Sport. Group A (middle weight category) included the athletes (n=12) with the body mass of 78 to 85 kg, Group B (heavy weight category) – 105 kg and over (n=12). The subjects’ special strength abilities were assessed using the tensodynamometry method.
Results and conclusions. The skilled armwrestlers and athletes of the heavy weight category (up to 110 kg and over 110 kg) were found to have significantly higher special strength fitness rates as compared to those of the middle weight category (80-85 kg). The largest differences between the mean strength values were found in the muscles involved in the forearm pronation, shoulder pronation, and wrist abduction (p<0.01). The smallest differences were found in the strength of the finger flexor muscles, forearm flexor muscles in the supine position, and wrist flexor muscles (p<0.05). The armwrestlers of the heavy weight category left those of the middle weight category behind in all the control tests.
