Factors affecting strength
1 muscle composition
1.1 the greater the...
1.2 % of fast twitch muscles fibres
1.3 x-sectional area of the muscle
1.4 muscle size
1.5 ...the greater the potential force that can be generated or applied
2 gender
2.1 little difference in strength between males and females, but...
2.2 females generally have less muscle mass, x-sectional area and muscle mass
2.3 they have less testosterone than men
2.4 ...therefore female strength is generally lower
3 age
3.1 female peak strength around 16-25yrs, male 18-30yrs
3.2 greatest gains = 20-30yrs= peak testosterone levels
3.3 strength decreases with age due to decreasing testosterone
3.4 less muscle mass, less efficient neuromusclar system
4 physical inactivity
4.1 atrophy = decrease in muscle size
4.2 48 hours of inactivity
4.3 induces loss of muscle strength gained from training
4.4 reversibility
5 strength training
5.1 specific strength training
5.2 increase hypertophy, decreases atrophy
6 the weakest point in the range of motion
6.1 specific to relative angle of the joint
