(HealthDay News) — Resistance training seems to be most effective for people with a low genetic risk for a high BMI, according to a study published in the International Journal of Obesity.
Researchers examined genetic markers of 148 women aged 30 to 65 years. All participated in the year-long Bone Estrogen and Strength Training study. Each woman received a genetic risk score for obesity, which was based on 21 genetic markers believed to affect body weight.
Eighty-four women were asked to participate in supervised, high-intensity resistance training and moderate weight-bearing exercises. The exercise sessions lasted for 75 minutes each.
The women were asked to do these exercises 3 days a week for 1 year. During this time, the women took calcium supplements but made no other changes to their typical diet. The participants recorded their food intake at random intervals.
The benefits of resistance training, which included weight loss as well as loss of body fat and abdominal fat, depended on a woman’s genetics and her risk for obesity, according to the study results.
More research is needed, the study authors pointed out, noting that future studies should include a more diverse group of people. Moreover, future studies should also identify ideal weight-management strategies based on an individual’s genetic profile, they added.
