Hi! I would describe this component in my own words by saying component is flexibility by saying that the three components of flexibility are muscle elasticity and length, joint structure and nervous system. Yes, these components of fitness are very important as they help us do the things in our daily lives. I would say the nerve system is more important than the rest with the joint structure coming in second place. We need the nervous system because they they transfer nerve impulses between the parts of our body. I hope this is what you were looking for, Goodluck!
It’s important because at this stage, teens are going through a more intense period of growth and learning. Teens must learn to mange their emotions/ feelings and think about how they feel and not acting out in a way that may hurt another person. If one is feeling angry, they must learn to not let that feeling control their behaviour such as hitting, screaming etc. And instead by talking it out with an adult, going for a walk to let out steam, listening to music etc.
