Muscle cell adaptation to physical activity is well known. Hypertrophy is one of the basic changes but metabolic changes are following the anatomic ones as well. The aim of the study was to follow up the changes of the ergometric parameters and surface area of the thigh muscles evoked by the heavy resistance strength training. The study included 15 male subjects, who took part in the heavy resistance strength training lasting 8 weeks. Anthropometric (surface area of the thigh muscles) and ergometric (peak power) parameters were measured at the beginning and at the end of the 8 week period in order to evaluate the changes in the thigh muscles. The surface area of the thigh muscles increased significantly (p < 0.05) (the left leg 9.26 +/- 10.32 cm2 and the right leg 9.07 +/- 0.57 cm2). Metabolic changes were assessed via Wingate test and also showed significant increase (p < 0.05). This finding indirectly indicates the increase in anaerobic capacity of the trained muscles. The heavy resistance training evidently influenced the changes in the trained muscles. After the 8 week period both antropometric and metabolic changes were evident, and significant.
