Young Sex Muscle They also had a significantly higher bone area of the total body, total femur, and the proximal femur than both other groups, and a significantly higher bone area of the tibia diaphysis, compared with the soccer group. A comparison of bone mineral density and muscle strength in young male adults with different exercise level. I boken porträtteras huvudpersonen som Erik Ponti. Dela den här bilden Dela länk Kopiera länk. Den enda segern av Jan Guillou. When adjusting for differences in lean mass and starting age of sport-specific training between the activity groups, the rope-skipping group had a higher BMD of the total body, lumbar spine, and right humerus compared with the soccer group. Bone density was also assessed in the radial forearm site of the dominant limb in the rope skippers and in 10 matched controls. BMD, bone mineral content BMC, g , and the bone area of the total body, lumbar spine, hip, femur and tibia diaphyses, distal femur, proximal tibia, and humerus were measured using dual-energy X-absorptiometry. Test-retest reliability based on continuous data is best analysed with several statistical indices — a specified ICC, method error statistics and analyses of systematic change in the mean. Kolumnisten av Jan Guillou Ofta obekväm, bara i undantagsfall politiskt korrekt och aldrig n Svenskarna, invandrarna och svartskallarna: Ondskan kassett av Jan Guillou. The bone area values at different sites were strongly related to muscle strength and height and less strongly related to the type of physical activity and pubertal stage. There were no significant differences between the groups but there was a strong tendency towards a lower estradiol level and a higher osteocalcin level in the amenorrheic group. Yet bone size was largely determined by parameters related to body size and less strongly to physical activity.

Blå stjärnan av Jan Guillou. Huvudet ska tas ned och rengöras separat. Sex-specific difference existed in the ECC mode — when muscle size and physical activity levels were accounted for men produced more ECC torque for the same amount of muscle. In conclusion, it appears that in late adolescent women, weight-bearing activities are an important determinant for bone density, and high impact activities such as jumping also seem to be associated with a modification of the bone geometry hence, the bone width at the loaded sites.

Hence, impact forces may be of greater importance in regulating bone mass than muscle strength in itself in highly trained athletes. Den demokratiske terroristen av Jan Guillou. The greater strength in men was almost exclusively explained by the greater muscle size, which, in turn, was determined by differences in body weight and fibre areas. In the cross-country group, on the other hand, muscle strength was a strong predictor of BMD, both at adjacent and more distant BMD sites. Logga in på vår webbplats för medarbetare.
