摘要：Background and aim. Body composition is one of key components of health in both general and athletic populations. In martial arts great significance is attached to the development of mesomorphy and strength, which are crucial for performing offensive and defensive actions during fights. The study proposes to introduce progressive strength training programme - arranged primarily for beginners – in order to improve body composition of non-elite male martial arts competitors. The present study aims to evaluate the changes in body massiveness, body composition and strength in 31 martial arts practitioners from academic sports clubs after a combined martial arts and strength training programme. Material and methods. The 16-week intervention was based on a targeted progressive resistance training protocol developed by Stefaniak [1995]. The anthropometric, physical and motoric measurements were performed twice at four months interval. This programme includes training three times weekly with increased number of repetitions (19-24), number of sets (1-3) and increased loads (5%). Results. After the completion of the training program, significant increase for about 1.8 kg in body mass was observed. Body massiveness (BMI) increased from 23.2 ± 1.8 kg/m2 to 23.9 ± 1.8 kg/m2. The analysis using Sheldon’s somatotypes revealed an increase of mesomorphy (from 5.5 to 5.7) and decrease of ectomorphy (from 2.5 to 2.4). The level of endomorphy became stable (2.1). The maximal circumferences of flexed arm, forearm, calf and thigh increased significantly of about 0.6-1.2 cm. The amount of fat mass remained unchanged, but the amount of fat free mass and muscle mass increased about 1.5 kg (MM from 43.7 ± 4.8 kg to 45.3 ± 5.5 kg). Back muscle strength increased of 10.0 kg. In left hand there was visible increase of grip strength, whereas right hand grip strength became stable. Conclusions. The results of the present study indicate that even experienced but non-elite academic male martial artists could improve their body composition and muscle strength by completing the proposed strength training programme together with martial arts training. The effect of symmetrization in hand grip strength is beneficial for sport performance and everyday movements practice.
