1
Q
what are the factors affecting flexibility
A
- type of joint
- length and elasticity of surrounding connective tissue
- gender
- age
2
Q
how does the type of joint affect flexibility
A
- Ball and socket joints (shoulder, hip) have a greater RoM in comparison to other joints e.g. hinge joints (elbow, knee, ankle)
- The size and shape of joints and their articulating bones can either aid or limit the RoM
3
Q
how does length and elasticity of surrounding connective tissue affect flexibility
A
- The greater the length and elasticity of the surrounding muscle, tendons and ligaments, the greater the RoM
- The greater the length, the greater the distance before the stretch reflex is initiated, preventing further RoM.
- The greater the elasticity, the greater the RoM at the joint
4
Q
how does gender affect flexibility
A
- Females are generally more flexible than males
- Females have higher levels of oestrogen and relaxin, the hormones responsible for muscle and connective tissue elasticity
5
Q
how does age affect flexibility
A
- Flexibility is greatest in childhood and declines with age
- Age-related decline in flexibility is due to a loss of elasticity in the connective tissue
