Analysis of theoretical link between physical training in handball as well as singularities of physiology and the effect of isometric muscle force on movement control of girls attending handball training sessions has been made in the Paper. A hypothesis has been raised that isometric muscle force and the balance of force of individual muscle groups should increase with age. The hypothesis has been raised based on the research data and the statement that muscle mass grew the most during adolescence because at that period the quantity of hormone testosterone affecting the rate of protein synthesis increases 10 times (Maclntosh, Gardiner, McComas, 2006). Muscle mass increases more due to muscle fibre hypertrophy (increase of the quantity of myofibril), because even if the quantity of muscle fibre increase, the increase is very insignificant. A research has been carried out by means of testing method the aim of which was comparison of changes in isometric muscle force in case of girls attending handball training sessions. 10 girls attending handball training sessions at Šiauliai City Sport School “Saulė” have participated in the research. |
