Background. Over the years, most fitness gyms have introduced different programs of physical exercise for groups (eg. Aerobics, TRX, step aerobics). In order to avoid accidents, it is important to personalize and monitor these programs by a professional gym instructor.

Aims. The aim of this study is to evaluate the association between activity plans, individual food intake and body composition.

Methods. A prospective analytical study was conducted during February-March 2019 in Târgu-Mureș, Romania. The study sample was represented by 35 subjects from a fitness gym that practices physical activity in groups. The data required for the study were collected using a foot-to-foot bioimpedance scale, a plicometer, a tape measure and a 3-day food journal.

Results. The subjects had an average intake of 19.92% proteins, 37.87% fat and 42.90% carbohydrates. Statistical correlations were noticed between the intake of proteins and the abdominal skinfold (p=0.03). Other associations were visible between the intake of fats and the waist measurement (p=0.009), along with correlations between the intake of carbohydrates and the triceps skinfold (p=0.002).

Conclusions. The connection between inadequate physical activity, with high intensity, and an unbalanced nutritional plan (high in proteins but low in carbohydrates) will lead to a minor change in body mass because of dehydration.
