Effectiveness and safety of varying intensity physical training in obese patients

AIM. To evaluate the effectiveness and safety of physical training of varying intensity in obese patients.

METHODS. A single-center open-label randomized trial of 37 obese patients. The patients were divided into three groups: group 1 — 15 patients 5–7 days a week for 60 minutes performed training walking at a speed reached at the level of 25–30% VO_2peak, group 2 — 15 patients 5-7 days a week for 40 minutes performed training walking at a speed reached at the level of 60% VO_2peak, group 3 — 7 Patients were trained to walk 3 times a week for 30 minutes at a speed reached at the level of 75-80% VO_2peak. The dynamics of BMI, OT, and TFN were analyzed (based on the assessment of oxygen uptake at the peak of PH (VO_2peak)).

RESULTS. The inclusion of patients in group 3 was prematurely discontinued due to poor tolerance of high-intensity interval training, therefore, a total of 7 patients were included in group 3. After 6 months of training, the most pronounced decrease in BMI and OT, as well as a greater increase in TFN, walking speed at the lactate threshold and the period of predominant fat absorption during physical training were recorded in group 1, whose patients trained at an intensity of 25–30% of VO_2peak. According to the results of the analysis of the observation diaries, a high frequency of adverse events was revealed in the group of patients performing moderate and high intensity training.

CONCLUSIONS. 1. FT with an intensity of 75–80% VO2peak not well tolerated by obese patients and is less effective compared to FT with an intensity of 25–30% and 60% of VO_2peak. 2. Aerobic workouts with an intensity of 25–30% VO_2peak are the safest and most effective in obese patients.
