Key result
Spinning alone or with caffeine reduces body fat ~23% in overweight and obese women.
Why the study?
Overweight and obesity increase cardiovascular disease risk, prompting investigation into the effects of caffeine supplementation and aerobic training on lipid profiles and resting blood pressure.

Does aerobic training and caffeine supplementation improve lipid profile and resting blood pressure in overweight and obese men?
Aerobic training, but not caffeine supplementation, improves lipid profiles and blood pressure in overweight and obese men.
Spinning training may reduce body fat in overweight women; leaves open effects on lipids or BP in men.
Background: Overweight and obesity are dangerous factors in the incidence of many cardiovascular diseases in overweight and obese men. Objectives: The purpose of this study was to investigate the effect of eight weeks of caffeine supplementation and aerobic training on lipid profile and resting blood pressure in overweight and obese men. Methods: In this quasi-experimental study, 40 male volunteers aged 40 - 50 years who met the inclusion criteria were selected and randomly divided into the four groups of: (1) control, (2) caffeine supplementation, (3) aerobic training, and (4) training + caffeine supplementation. Written consent was obtained from all the subjects. Groups 3 and 4 performed training according to the training protocol for eight weeks and three sessions per week, and groups 2 and 4 consumed 5 mg/kg caffeine daily. Data were analyzed using one-way ANOVA and Tukey’s test, and P value less than 0.05 was considered significant. Results: Aerobic training as well as caffeine supplementation and aerobic training had a significant effect on the improvement of lipid profile and mean arterial blood pressure in overweight and obese men (P ≤ 0.05), but caffeine supplementation had no effect on any of the lipid profile variables (i.e., LDL, HDL, CHOL, and TG) or mean arterial blood pressure in overweight and obese men (P > 0.05). Conclusions: It seems that aerobic training can have beneficial effects on lipid profile and blood pressure in overweight and obese men.

Aghajari et al. (2020) conducted an RCT in Overweight and obesity (n=39). Spinning training and caffeine vs. Control (no intervention) was evaluated on Change in body fat percentage (p=<0.001). An 8-week spinning training program, alone or combined with caffeine, significantly reduced body fat percentage by 22.5% compared to control in overweight and obese women.
