Factors affecting strength
  1. muscle composition
    1. the greater the...
      1. % of fast twitch muscles fibres
        1. x-sectional area of the muscle
          1. muscle size
            1. ...the greater the potential force that can be generated or applied
            2. gender
              1. little difference in strength between males and females, but...
                1. females generally have less muscle mass, x-sectional area and muscle mass
                  1. they have less testosterone than men
                    1. ...therefore female strength is generally lower
                    2. age
                      1. female peak strength around 16-25yrs, male 18-30yrs
                        1. greatest gains = 20-30yrs= peak testosterone levels
                          1. strength decreases with age due to decreasing testosterone
                            1. less muscle mass, less efficient neuromusclar system
                            2. physical inactivity
                              1. atrophy = decrease in muscle size
                                1. 48 hours of inactivity
                                  1. induces loss of muscle strength gained from training
                                    1. reversibility
                                    2. strength training
                                      1. specific strength training
                                        1. increase hypertophy, decreases atrophy
                                        2. the weakest point in the range of motion
                                          1. specific to relative angle of the joint
