Abstract

Abstract : The effects of football training on bone health were examined in 55‐ to 70‐year‐old sedentary women and men with prediabetes. Patients (n = 50) with prediabetes (age; 61 ± 9 years, BMI 29.7 ± 0.6 kg/m 2, body fat content; 37 ± 1%, VO2max ; 22.7 ± 0.8 mL/min/kg and mean arterial pressure; 104 ± 3 mm Hg) were randomized into a football training group (FTG; n = 27, 14 women) and a control group (CON; n = 23, 11 women). At baseline, 73% and 24% were diagnosed with femur osteopenia and osteoporosis, respectively. FTG performed football training twice weekly 30‐60‐minute sessions in 16 weeks, and both FTG and CON received professional dietary advice. Pre‐ and post‐intervention whole‐body and regional bone mineral content (BMC) and density (BMD) were determined with DXA‐scans, and venous blood samples were drawn and analyzed for plasma bone turnover markers. Change scores were greater ( P < 0.05) in FTG compared to CON in leg BMD (0.023 ± 0.005 vs −0.004 ± 0.001 g/cm 2 ) and in leg BMC (32 ± 8 vs −4 ± 6 g). Between‐group changes in favor of FTG ( P < 0.05) also occurred in the femur neck BMD (3.2%) and femur shaft BMD (2.5%). Whole‐body BMC and BMD were unchanged in both groups during the intervention. In FTG, resting plasma osteocalcin, P1NP, and CTX‐1 rose ( P < 0.05) by 23 ± 8, 52 ± 9 and 38 ± 7%, with greater change scores ( P < 0.05) than in CON. Finally, P1NP (formation)/CTX‐1 (resorption) ratio increased ( P < 0.05) in FTG (127 ± 15 vs 150 ± 11) from pre‐ to post‐intervention, with no change in CON (124 ± 12 and 123 ± 12). In conclusion, football training provides a powerful osteogenic stimulus and improves bone health in 55‐ to 70‐year‐old women and men diagnosed with prediabetes.
