Answer:
30 minutes
Explanation:
The case of being physically inactive has been an issue of growing concern, with less and less adults engaging in physical activity constantly. This led to the United States Department of Health and Human Services (HHS) to report that only 24% of adults participate in a minimum of 30 minutes of light-to-moderate physical activity at least five times per week.
The process that must occur is the recruitment of motor units.
Muscles allow us to lift heavy things. They are made of fibers, that when they contract themselves, the tension increases, allowing us to lift objects.
When we want to lift a heavy object, our body contracts the necessary muscles that we will use for that. In other words:
- The motor neuron that innervates several skeletal fibers sends the signal to them
- The fibers contract themselves,
- The tension increases, producing the necessary force to lift an object.
If the object is too heavy and we can not lift it, the process that must occur is the recruitment of motor units. That is to say, that more motor neurons with their fiber muscles (motor units) should be activated to increase the number of fibers contracting themselves to lift the heavy object.
In conclusion, the muscle needs more active motor units to lift something heavy, and the body does this through recruitment.
