Cardiovascular Effects of Exercise

Question

Describe and explain trends in your data obtained in Exercise 3 (forearm exercise). How might this data differ if you were to have done the same experiment with a much larger muscle / set of muscles (ex: thigh muscles)?

 

Didn't obtain any data but I still have to answer as though I do have data but I am so confused. 

 

Answer 1

Hi heather,

 

Muscles store glycogen.

 

Larger the muscle, more glycogen  it may store as reserve.

 

During steady rate exercise, the stored glycogen provides energy for the physical activity or exercise that one selects (swimming, biking, running, walking etc.).

 

During aerobic exercise, oxygen is utilized and body tends to use it more efficiently when a person is trained in that particular activity. 

 

During anaerobic exercise, lactate is produced and its accumulation causes fatigue. In trained, individuals, lactate is immediate broken down and therefore, accumulation is slower and they can continue with exercise for longer duration. 

 

Depending on the kind of exercise, state of training and availability of oxygen, data will vary.

 

Hope you get the point. Please post again or contact me if you need additional information/explanation. 

 

Best,
