    Objectives: This study aims to examine effects of aerobic jogging and explosive power exercises on body composition, maximal oxygen consumption (MaxVO(2)), bone mineral density (BMD) and bone turn-over markers: serum bone alkaline phosphatase (BAP), C terminal telopeptide (CTx), Procollagen type I N-terminal propeptide (PINP), in men aged between 20 and 40. Materials and methods: Thirty seven healthy males were divided into exercise group (EG, n = 19) and control group (CG, n = 18). EG completed 10 weeks of outdoor aerobic (jogging at 60-70% maximal heart rate reserve starting from 20 min steadily increasing up to 28 min) and explosive power exercises (in 2-3 sets, with maximum repetitions lasting 15 s), 3 times per week. All measurements were taken before and after the exercise program. BMD was measured via dual energy X-ray absorptiometry (DEXA). Results: Body mass index (p < 0.001) significantly decreased; MaxVO(2) (p < 0.001), femur neck (p = 0.036) and total score BMD significantly increased in EG (p = 0.034). BAP and vitamin D increased in both groups (p < 0.001). Conclusion: Performing our outdoor exercise program in spring months might have an important role in the significant increase (9 vs. 22 ng/mL) in mean vitamin D level, which reached above the fracture risk level of 20 ng/mL.
