CRITERIA FOR AN EFFECTIVE KETTLEBELL CLEAN AND JERK

Abstract

Aim. The purpose of the study is to develop criteria for an effective kettlebell clean and jerk. Materials and methods. The study involved males aged 18–22 engaged in kettlebell lifting (n = 11, from 1^st rank to the Master of Sport of Russia). The athletes performed the kettlebell clean and jerk in different modes. Exercise duration did not exceed 2 minutes. During the exercise, the ground reaction force was recorded. Results. During multiple performances of the exercise, ground reaction force did not reach the maximum possible values. Highly skilled athletes apply as much effort as needed for the efficient performance of the exercise. With performance enhancement, an increase in FGR_max occurs. The use of FGR_max data in training planning will allow for identification of the means and methods aimed at improving this parameter. Half-squat has a great impact on FGR_max. Its effectiveness can be estimated by the diffe­rence in FGR_max values when lifting kettlebells with and without the half-squat position. The greater the difference, the greater the effectiveness. Minimum FGR_min values characterize the lifting method. The speed-power method is characterized by FGR_min ranging from 100 to 300 N. The power method is characterized by a higher FGR_min. When FGR_min = 0, a flight phase appears, which reduces the effectiveness of the exercise. When the kettlebell reaches the chest in the squat position, the effectiveness is measured as FGR_max. Reduced values of FGR_max in the squat phase will be indicative of decreased load on the musculoskeletal system and increased effectiveness of kettlebell chest contact. Conclusion. The criteria of an effective clean and jerk exercise will allow for substantiating new approaches to the training of kettlebell lifters.
