Abstract:

The study was conducted on a sample of 60 adult volunteers from Romania, aged 20, with sedentary lifestyle, grouped into the following categories: normal weight, overweight and obese (World Health Organisation). The study lasted nine months and investigated the evolution of several fitness parameters which represent the expression of health state of a human adult organism: direct indicators of development (height, body weight, fat mass, and the maximal oxygen consumption-VO_2max) and complex indicators (body mass index-BMI). The subjects consisting of adult persons, women and men, have followed a specific program of physical training aiming the two components of the fitness: aerobe and muscular. The training frequency has been three times a week and respectively one hour daily for each subject. Also, the proportion of proteins, carbohydrates and lipids administrated to each person during the study has been identical, being respected in the same time the differences arising from the body weight. The results showed that following physical training and controlled nutrition all the four analysed parameters have been improved. In three categories, positive correlations between BMI and body fat mass have been found both in women and in men and also significant inverse correlation (p<0.05) between the VO_2max increase and the decrease of body fat mass. The most significant differences between the initial and final values of the studied parameters have been recorded in overweight and obese categories. At the end of physical training, the improvement in the fitness of participating subjects has been recorded (weight loss, decrease of body fat mass, VO_2max increase), new ratio between elements of body composition, and the re-classification in another BMI category.
