Abstract

INTRODUCTION. The aim of the study was to compare vital capacity and ventilation, heart rate, aerobic threshold and lactate concentration in obese women in relation to the length of exercise on cycloergometer.
MATERIAL AND METHODS. The study involved 34 obese women (age 36.2 ± 13, body weight 95.5 ± 16.5 kg; BMI 36.0 ± 5.7 kg/m2). All subjects performed a cycloergometer stress test (0–3 minutes - 50 W; 3–6 minutes - 100 W; 6–9 minutes - 150 W) (Ketler program). Heart rate during test was recorded using a pulse oximeter. Spirometry was carried out before the test. Lactate concentrations were measured before and after the exercise test. Subjects were divided into two subgroups in relation to the duration of the exercise test.
RESULTS. Higher heart rate was observed in the subjects who performed the exercise test longer than 6 minutes. There were no differences in the percentage of maximal heart rate and maximum oxygen consumption (VO2max) between groups. The accumulation of blood lactate during exercise and vital capacity (VC) was greater in the group with higher work load. There were no differences in total lung volume (TLV) in both groups.
CONCLUSIONS. Age, body mass, BMI, fat mass, vital capacity (VC), maximum oxygen consumption (VO2max) and the percentage of maximal heart rate seem not to influence the duration of the exercise test’s duration. It seems that physical fitness in obese women depends on the level of training.
