-the greater the:
(a) % of fast twitch muscle fibres.
(b) cross sectional area of muscle.
(c) muscle size
the greater the potential force that can be generated or applied.
-There is little gender difference in strength between males and females, except that female strength is generally lower than males because :
- females generally have less muscle ***, cross-sectional area and muscle size.
- they have less testosterone than males.
-female peak strength is reached between the age of 16-25: for males it's between 18 and 30 years.
-greatest gains are made between the age of 20 & 30 years for both genders, when testosterone levels peak.
- strength generally decreases with increasig age due to a decrease in testosterone leading to less muscle mass and a less efficient neuro-muscular system.
- Atrophy (decrease in muscle size) starts after approximately 48 hours of inactivity and induces the loss of muscle strength already gained from training (reversibility)
- Appropriate/ specific strength training increases strength/hypertrophy while preventing atrophy
Weakest point in the range of motion
WEAKEST POINT IN RANGE OF MOTION
- this is specific to the relative angle of a given joint.
- APPLY IT TO ALL: well trained distance runners may have 80% slow twitch fibres in their leg musles, whereas by contrast sprinters may have up to 75% fast twitch fibres. Middle distance runners and typical team game players often have a more equal distribution of fibre types.
