Opis:
The study assesses the effects of a six-week plyometric training program (PT) on muscle stiffness in the dominant and non-dominant leg in male collegiate volleyball players. The study group comprised 16 volleyball players who had played collegiate volleyball for at least four years. For six consecutive weeks, twice a week, the players undertook a plyometric program of 60-min training sessions, each preceded with a specialist warm-up. The analysis of the anterior muscles of the right and the left lower leg revealed a significant increase in stiffness in the muscles of the right leg and the left leg. No significant differences were found between the anterior muscles of the left lower leg and the right lower leg in particular weeks of the training program. The analysis of the posterior lower leg muscles revealed no significant differences, either in the consecutive weekly training microcycles or between the left leg and the right leg. The measurement of muscle tone and biomechanical properties of muscles can be used as a fast and direct assessment of plyometric training-related muscle fatigue. A similar level of muscle stiffness in both lower legs (symmetry) is a reflection of the appropriate selection of plyometric training loads.

Opis:
The article presents the findings of the research conducted in order to learn physical education teachers’ opinions on the implementation of the health edu- cation content. The study was carried out in lower and upper secondary schools located in the region of Upper Silesia (Poland). A quantitative method was used to gather and analyse data. The survey was conducted with a specially designed questionnaire including 17 items. The research was based on the analysis of core curriculum concerning the objectives and content of health education planned to be implemented during physical education classes in lower and upper secondary schools. The research allowed for identifying potential gaps and good practices in school-based health education and health promotion in the Polish socio-cultural conditions.
