effects of aerobic exercise concurrent with caffeine supplementation on weight and body fat among overweight women

Background: obesity and overweight are among serious global epidemics that significantly threaten human health, especially among women. objectives: this study aimed to assess the concurrent effects of 6-week caffeine supplementation with moderate-intensity aerobic exercise on weight and body fat among overweight women. methods: thirty overweight females (age: 36.47 ± 6.48 years; bmi: 27.61 ± 1.54 kg/m²; mean ±sd) with a sedentary lifestyle were recruited to the study. the participants were randomly allocated to the experimental group, ec (exercise + caffeine) group, who took 100 milligrams of caffeine of the “api” brand supplement 30 minutes before exercise training (n = 15) or control group, ep (exercise + placebo) (n = 15). all participants performed moderate-intensity aerobic exercise with an intensity of 40 to 60% of heart rate reserve based on the individual’s exercise test for 30 minutes, three days a week for six weeks. measurements, including the percentage of body fat, waist circumference, and skinfold (suprailiac, abdominal), were done two times, at baseline and after six weeks of exercising. results: there were no significant differences between control and experimental groups related to weight (p = 0.22), percentage body fat (p = 0.88), and other measurements after six weeks. conclusions: 6 weeks of caffeine supplementation combined with moderate-intensity aerobic exercise without dietary interventions couldn’t make a significant reduction in weight and central or total body fat among overweight women.
