Abstract

AIM Objective of the study was to determine the effects of a periodized resistance training program on body composition, plasmatic levels of leptin and resistin, and muscle strength in elderly post-menopausal women. METHODS Twenty-three post-menopausal women (age= 63.02±4.42 years; height 1.55±0.06 m; body mass 67.56±2.26 kg) were submitted to 12 months of periodized resistance training twice a week. The training program consisted of 3 sets of 6-14 repetitions maximal (RM). Body composition (DXA), muscle strength (bench press, leg press 45º and arm curl), plasmatic levels of resistin and leptin (ELISA method) were assessed before and after the training program. Paired Student's t test was used for comparison between pre- and post-training values. RESULTS There was a significant increase in muscle strength and lean body mass; decrease in body mass, body fat percentage and fat mass after 12 months of resistance training, a part from the decrease in leptin and resistin levels. CONCLUSION Long-term periodized resistance training prevents aging sarcopenia, decreases body fat and systemic markers of inflammation in postmenopausal elderly women.

Prevention Is Better than Cure—Body Composition and Glycolipid Metabolism after a 24-Week Physical Activity Program without Nutritional Intervention in Healthy Sedentary Women

A 24-week endurance-resistance physical activity program improved body composition and carbohydrate and lipid metabolism in normal-weight, healthy women, reducing obesity and metabolic disorders.

A single session of strength training changed plasma levels of resistin, but not leptin in overweight and obese men

A single session of strength training significantly decreased plasma levels of resistin without altering leptin levels in overweight and obese men, supporting exercise benefits in reducing low grade inflammation and insulin resistance.

Reduction of leptin levels during acute exercise is dependent on fasting but not on caloric restriction during chronic exercise: A systematic review and meta-analysis

Both acute and chronic exercise reduce leptin levels, with the acute effect depending on the pre-exercise meal, and a minimum of 180 minutes of moderate-intensity or 120 minutes of high-intensity exercise weekly is needed for significant reduction.

The Power of Resistance Training: Evidence-based Recommendations for Middle-aged and Older Women's Health

Regular resistance training can improve muscle strength, increase bone density, and reduce the risk of falls and fractures in middle-aged and older women, promoting healthy aging.

8-12RM is more effective for upper limb strength in older women, while 10-15RM is more effective for lower limb strength and metabolic adaptations.

Resistance training positively influences adipokine levels in postmenopausal women by improving body composition and lean-muscle mass/fat-mass ratio, but more research is needed to understand their anti/inflammatory response.
