摘要：There is no consensus exercise programme to reduce body weight and improve body composition simultaneously preventing bone loss or stimulating osteogenesis. This pilot study compared the effect of endurance and endurance-strength training on body composition and bone metabolism in centrally obese women. Recruited subjects were randomly assigned to three-month endurance ( n = 22) or endurance-strength training ( n = 22). Body composition, bone mineral density (BMD) and content (BMC) were assessed before and after the intervention and markers of bone formation and resorption were measured. Both training significantly decreased fat mass; however, endurance-strength training had a more favourable effect on lean mass for the gynoid area ( p = 0.0211) and legs ( p = 0.0381). Endurance training significantly decreased total body BMC and BMD ( p = 0.0440 and p = 0.0300), whereas endurance-strength training only reduced BMD ( p = 0.0063). Changes in densitometric parameters did not differ between the groups but endurance training increased osteocalcin levels ( p = 0.04845), while endurance-strength training increased tartrate-resistant acid phosphatase 5b concentrations ( p = 0.00145). In conclusion, both training programmes were effective in the reduction of fat mass simultaneously negatively affecting bone health. However, endurance-strength training seemed to be more effective in increasing lean mass. The study protocol was registered in the ClinicalTrials.gov database under the number NCT03444207, date of registration: 23 February 2018 (retrospective registration).
