Introduction. The difference between 24-hour daily energy intake and total
daily energy expenditure determines whether we lose or gain weight. The
resting metabolic rate is the major component of daily energy expenditure,
which depends on many different factors, but also on the level of physical
activity. The aim of the study was to determine anthropometric and metabolic
parameters of athletes engaged in different types of training, to compare
obtained results and to examine whether there are statistically significant
differences among them. Material and Methods. The study included a total of
42 young male athletes divided into two groups. The first group included 21
athletes who were predominantly engaged in aerobic type of training, and the
other group of 21 athletes in anaerobic type of training. Anthropometric
measurements were taken and resting metabolic rate was assessed using the
indirect calorimetry method. The results were statistically analyzed and the
differences in parameters between the two groups were compared. Results.
Statistically significant differences were established in total body mass,
amount of fat-free mass and muscle mass, body mass index, as well as in the
relative metabolic indices between two groups of subjects. Conclusion. The
percentage of fat-free body mass has the greatest impact on the resting
metabolic rate. The rate of metabolic activity of this body compartment is
higher in athletes engaged in aerobic than in athletes engaged in anaerobic
type of training.
