Document Summary
Muscular strength the ability of muscle to exert max force mass contractile force against resistance. Muscular endurance capacity of skeletal muscles to sustain contractions at submax max resistance. The components of muscle - muscular strength, muscular endurance, bone strength. Increase in ability to carry out daily living activities strength decreases with age. Concentric- force exerted by muscle or muscle group exceeds external resistance. Eccentric- joint angle increases, muscle lengthens while contracting. Client squeezed grip tight and quickly and release pressure. Do 3 trials each hand, 1 min rest between trials. Warm up 5 to 10 minutes. Rest incorporate stretches for relevant muscle groups. Client performs 3 to 5 reps at 60 to 80% of 1 rm. Rest 3 to 5 min between trials. Highest weight lifted with good form is 1 rm. Subject performs many contractions at submax and use equation to estimate 1rm. Client lies with feet bent at 90 degrees.
