Introduction. The aim of this work was to assess bone mineral content (BMC) and bone mineral density (BMD) in male athletes performing weight-bearing and weight-supporting sports activities as well as in untrained men.
Material and methods. The study included 140 men aged 20-23. The study group consisted of wrestlers, football players, cyclists and untrained men. BMC (g) and BMD (g/cm2) in the lumbar spine (L2-L4) were determined with the use of the DEXA method. Biochemical parameters (concentration of osteocalcin, testosterone and 25-OH vitamin D in blood) were measured using the ELISA method. Diet composition was assessed based on three individual questionnaire interviews regarding nutrition in the last 24 hours prior to the study.
Results. Statistical analysis revealed that wrestlers demonstrated the highest levels of parameters related to bone mass. In this group, mean values of BMC, BMD as well as BMD compared to peak populational bone mass were significantly higher than in cyclists and the men from the control group. In the case of BMD (g/cm2), the difference was at the level of p < 0.001, whereas in the remaining parameters, i.e. BMC (g) and BMD with reference to age (%), it was at the level of p < 0.01. No significant differences between the groups were observed in the concentration of osteocalcin, testosterone and 25-OH vitamin D in blood and in nutrition.
Conclusions. Athletes who perform sports that predispose to the development of bone pathology should also do exercises that would support bone mineralisation and prevent osteoporosis in the future.
