(a)
To calculate: The power expenditure of each runner whose masses are 60kg, 65kg and 70kg, running at 400m/min.
(b)
Whether the power expenditure increase or decrease as the mass of the runner increases with constant velocity.
(c)
To calculate: The velocity of each runner whose masses are 80 kg, 84kg and 90 kg, expending power at
(D)
Whether the velocity increases or decreases as the mass of the runner increases with constant power expenditure.
(e)
To calculate: The velocity of a 50 kg runner expending power at same rate while carrying 2 kg extra weight and being trained at velocity 480 m/min.
(f)
The reason for the runners to carry extra weight while being trained.
(g)
To graph: Power expenditure versus mass of a runner with velocity fixed at 400 m/min and velocity versus mass of a runner with fixed power expenditure at 40 kcal/min with the use of computer.
