[Evaluation of energy requirements in basic physical activity].
When evaluating the influence of physical activity on the organism it is important to know its energy requirement. A positive influence is exerted only by those physical activities, when during their application a certain minimal threshold level is exceeded. The level depends on the purpose for which these activities are performed. When evaluating the energy requirement of different physical activities, it is important to respect body weights of the investigated subjects. The coefficient of energy requirement is expressed in kJ.min-1.kg-1. The author presents values of basic physical activities which may be used by the public. Based on a cross-sectional survey of the Czechoslovak population the authors recommend for stabilization of the attained level of physical fitness and performance a minimal extra physical activity expressed as the energy output per week and amounting to 6000-8000 kJ per week. To achieve an increasing effect, this level must amount to at least 13,000 kJ per week.
