List and explain 2 advantages and 2 disadvantages for each method of ergometry used 3. Calculate Work and Power for each method of ergometry at each level. Discuss your resultsExplanation / Answer
1. Ergometry: Ergometry is a sience that measures work. A device that can be used to measure work is called an enrgometer. (W = F x D)
2. Work: a) Work is the energy required to move an object a force. It is equal to the force times the distance the object moves.
b) ( cycling W= 4kgs x 75 rpm x 3min = 900 kgm, Power (P)= 900/3 = 300 kgm/min) (stepping W= 65.5kgs x 12 step/min x 0.27M x 3min = 639kgm, power(P)= 639kgm/3min = 213 kgm/min)
3. a) Power: Power is work expressed relative to time. Ex: Cycling and stepping. (P= Kgm/Min)
4. a) Stair-stepping: Advantages: Stair-stepping can provide an intense cardiovascular workout, It is good workout for the thigh and glutes.
Disadvantages: Not well suited for building up muscles. Put a great strain on the knees than cycling.
b) Cycle ergometry: Advantages: It is effective for exercising the thigh muscles. It is good for joints and do not put a lot of strain on the knees.
Disadvantage: One is not able to exercise outdoors in the fresh air. Only the leg and gluteal muscles are exercised.
c) Treadmills: Advantages: One is not dependent on the weather, The load is easy to adjust. One does not need a jogging route.
Disadvantages: It is relatively loud and monotonous noises, Your can not get fresh air.
