The Association between Physical Fitness, Body Composition and Bone Mineral Density among Female Athletes

摘要: Background: Research have suggested that endurance female athletes tend to lower bone mineral density (BMD) than power and strength athletes, as a result of maintaining low body weight in addition perform. This study intends investigate the association between physical fitness by measurements, composition BMD. In addition, it will address differences BMD measured football players, handball players cross-country skiers.Methods: A cross-sectional 57 Norwegian aged 18 36 years (mean age 22.6 years) was conducted. The sample consisted 24 17 16 skiers. For examinations, graded VO₂max (ml/kg/min) test on treadmill, squat jump plate bench press with free weights were Body height BMI calculated from aforementioned variables. Lean mass, fat percentage (g/cm²) using Dual- Energy X-ray Absorptiometry. obtained four different regions, total BMD: Ward’s triangle, Trochanter, femoral neck lumbar region (L1-L4).Results: Significant observed for all subjects combined. Also, significant associations tests obtained. Differences level among indicated skiers had weight, BMI, lean mass percentage. Cross-country also highest mean oxygen consumption lowest regions. Handball higher values regions measured.Conclusion: strongly associated measured. Subjects high measurements while muscular three sports both measured.Keywords: Female fitness, composition, (BMD).
