During strenuous exerciseGroup of answer choicesan oxygen debt can occur.lactic acid can be created in the muscle.almost all the contractions are tonic contractions.an oxygen debt can occur and lactic acid can be created in the muscle.
Solution
During strenuous exercise, both an oxygen debt can occur and lactic acid can be created in the muscle.
Here's the step by step explanation:
-
When you exercise, your body needs to produce more energy to meet the increased demand. This energy is produced by breaking down glucose in the cells, a process that requires oxygen.
-
If the exercise is strenuous and the body can't supply enough oxygen to the muscles fast enough, the body starts to produce energy anaerobically (without oxygen). This is when an oxygen debt occurs.
-
The anaerobic process of energy production results in the creation of lactic acid in the muscles. This is a temporary solution for the body, as lactic acid can build up in the muscles and cause fatigue and discomfort.
-
Tonic contractions, on the other hand, are continuous, low-level contractions that do not produce movement. They are not typically associated with strenuous exercise, which usually involves phasic contractions (contractions that produce movement).
So, during strenuous exercise, an oxygen debt can occur and lactic acid can be created in the muscle.
Similar Questions
lactic acid is produced whenever muscle tissue contracts. Muscle tissue can contract in the absence of oxygen and lactic acid accumulates until fatigue sets in. On return to Aerobic conditions, the muscle tissue can contract again and the lactic acid is metabolised. Which of the following is the best interpretation of these observations?: A= formation of lactic acid is oxygen dependent, B= in anaerobic conditions, lactic acid is produced faster then it can be removed,C= lactic acid is produced only in anaerobic conditions,D= muscle contraction is independent of oxygen availability.
