Before maturation, we do not notice the differences between sexes, however, after the maturation period, the changes can be significant. Therefore, a precise determination of the caloric requirement for a teenage athlete is a very difficult issue due to metabolic variability within individuals, as well as methodological difficulties when determining caloric consumption and its delivery.


The consumption of energy by teenage athletes should provide adequate support and development, while providing energy needed for physical activity and goals.
The concept of energy availability is useful in understanding the importance of adequate energy consumption, ensuring proper growth of adolescent athletes appropriate for a specific period of maturation. A positive energy balance is suggested, i.e. consumption should exceed energy losses generated during daily activities (consumption > use). The availability of energy differs from the traditional method of calculating caloric requirement, taking into account the following definition: Energy availability = energy consumption - energy use exercises.

This concept focuses on the amount of energy that remains after deducting energy intended for physical activity, the rest is intended for other processes and functions of the body. In the case of too low or too high energy consumption the fact of adverse health effects is confirmed. Low energy availability among teenage athletes in adolescence can have a significant impact on health, delayed maturation, menstrual disorder, and negative effects on the skeletal system. A negative energy balance can cause muscle loss and adversely affect the strength and growth, as well as the development of a young player. On the other hand, chronic and significant exceedance of caloric requirement can lead to well-documented health problems such as obesity, overweight, type II diabetes and can increase the risk of injuries. The most practical method to assess energy consumption is to assess energy consumption and compare it with simultaneous energy use measures for physical effort, and a simultaneous determinant of energy loss on physical activity and adequate energy supply, as well as assessment of development analysis using centile grids. A traditional method for calculating the caloric requirement is the PAL activity coefficient and the basal energy use calculated using standard formulas for calculating the caloric requirement.
