Document Summary

Sport: greater power, speed, balance, reduce demands on cardio. Job/occupational requirements: reduced risk of injury, productivity. Lower risk of functional limitations: avoid injuries, predicts advanced age disability, reduces chronic low back pain. Endurance type 1 muscle fibre higher %, low type 2 % Maintaining or improving muscular strength later in life reduces the percentage of functional limitations over 50% for both men/woman. Muscle strength across the lifespan (static, dynamic, pull strength and muscular endurance: paediatric years childhood to young adult, elderly. ** if you train as young adult, relatively maintain strength through old age** (does decrease) 1-2% muscle mass per year past 50 yrs of age loss of strength varies/ may be greater: prevalence. Impacts 10-25% of the population under age 70 and 40% above age 80 loss of muscle mass and strength due to aging. By 80 yrs a loss of 30-40% of muscle fivers (hypoplasia of muscles containing type ii muscle fibers: concerns.
