Document Summary

Strength is not only important for sports performance but also to perform basic adls (activities of. Daily living: basic things like caring for yourself, going into the shower, adls depend on minimal level of strength. Strength increases as children grow: muscle mass growth follows sigmoid pattern, puberty more hormones. Boys and girls are similar in strength levels until age 13 years. Neural factors likely exert influence (including improved motor until activation with maturation) Males add more muscle mass in adolescence. Age vs. muscle force: handgrip (boys and girls, elbow extension (boys and girls, leg lift (boys and igrls) Linear increase in strength up to 13 then divergence after puberty. Leg lift boys have a linear increase throughout; girls stop increasing at 13. Muscle mass declines in the average older adult. Loss of strength may be greater than loss of muscle mass (possibly due to changes in fiber types, nervous system, vascular system)
