more power, speed, and balance, reduce demands on cardiovascular system. Why is strength important? y performance related: sport, job. productivity y health related: lower risk of functional limitations, lower risk of chronic diseases, psychological health. avoiding injuries, predictor of advanced age disability, reduces chronic low back pain. Improved blood sugar control, retard/ prevents osteoporosis, incr metabolic rate: emergencies- fight or flight situations.

Training when done in an appropriate manner will result in gains, and levels are retained. There is always a decline in strength as we age; improving strength will only slow it down. Apoptotic pathways y y when activated they activate other caspases and can result in dna fragmentation and.
