What is Ergometry?
It is the measurement of mechanical energy production
What is an Ergometer?
It is a device from which work and power can be determined. (its not really measuring your work, because it doesn’t measure wind, slippery, shoes, or weight.) They are measuring the net outcome.
The estimated energy used when exercising depends on:
1) Whether weight-dependent exercise mode, e.g. run vs row
2) Exercise efficiency
What is the equation for force?
Mass x acceleration
What is strength?
It is maximum force that can be produced by a muscle group in a single movement
What are things that can influence strength?
1) muscle size
2) fibre type proportions
3) fibre orientation
4) neural activation
5) metabolic factors
What is Work?
It is the energy imparted into an object when it is moved to a position of higher potential energy.
What is the equation for work?
force x displacement
What is the equation for power?
work/time
or
force x distance/time
What is the equation for efficency
work rate / metabolic rate x 100.
(Can calculate it only when can measure power output)
