The sample included 27 recreationally active women, experimental group (n = 13; age: 34.6 ± 1.7) and control group (n = 14; age: 34.2 ± 1.9). Nine parameters were measured: body weight, body height, body mass index, adipose tissue in%, adipose tissue in kg, muscle tissue in%, muscle tissue in kg, lean body mass in%, lean body mass in kg. Statistically significant effects on the final measurement were determined in the following tests: body weight in kg, body mass index, adipose tissue in%, adipose tissue in kg, muscle tissue in%, lean body mass in% and lean body mass in kg, at the level of statistical significance p<0.05. The results confirmed that intensive training of high intensity ≥80%-90% HRmax, was effective and lead to statistically significant changes in body composition.
