The aspects of optimal weekly physical exercise
PROCHÁZKA, Michal
This thesis focuses on the health aspects of physical stress and points to possible problems in the case of no or on the other hand exaggerated physical activity. The work is based on an analysis of Czech and foreign professional literature that relates to the issue of the contemporary physical activity and its health aspects. In this work, I found that the author, who follow up physical activity, concur in the opinion that regular physical activity has many positive aspects (physiological, psychological but also social) on the body, but with prerequisite for the proper dosage. Physical activity may arise injury, or pathological condition associated with hard excercises (overtraining, overvoltage). The authors clearly agree we recommend aerobic activity rate 3-5 exercises per week. The execution time of individual operations depends on the intensity of activities performed. In various publications can be found with different recommendations duration of action, but all authors agree that if the activity is carried out by a lower intensity, it should be longer respectively, less time for intensive activity. Low intensity physical activity should take at least 45 minutes, load of medium intensity 30-60 minutes, high intensity exercise requires a maximum of 20 minutes. The time of exercises is variable with respect to the current state of the individual. It is appropriate to switch between different physical activities, alternating aerobic and strengthening exercises. The most convenient way is the inclusion of two days a week to fitness exercise plan, which will strengthen large muscle groups. In this work, I sort through and systematically elaborated health aspects accompanying physical exercises, pointed to changes in the body corresponding to the use of physical activity.
