To investigate the effect on maximum power, when the proportion of arm length to body height is changed.
I predict that the increase of proportion linking arm-span to body-height will increase the maximum power. Although the increase of arm-span also corresponds to the increase in weight, this will have minimal effect, (due to limitations). If the proportion is large, this will mean that the thrust force of the body during exercise will be more, since the moving arms add to the force forwards, therefore increasing the maximum power.
• Proportion linking Arm-span to height e.g. height (cm)/arm-span (cm)
• Maximum power (watts)
• Ground Surface
• Age (approximate).
• Lung Capacity (approximate)
• Temperature of setting
• Measuring experiment
• Body type
• Effort during exercise e.g. use of arm thrust.
• Existing fatigue
• Physical injuries
• Health problems
