Abstract
The downturn in children's interest in physical activity leads to a decrease in condition and the occurrence of civilization diseases, namely obesity and osteoporosis. The solution can be found in broadening the supply of physical education in schools and after-school physical activities that can children perform even on their own, without the necessity of high financial expenses.
These activities should in long terms fulfil the parameters of suitable load, which will lead to positive changes in bone tissue density (Weeks, Young, & Beck, 2008) and enhancing the condition parameters (Sollerhed & Ejlertsson, 2008). Various applied intervention programmes have proven that in this point of view, the rope skipping seems to be a suitable application.
