Explain how each of the three principles of cardiovascular fitness can lead to injury if they are not adhered to properly.

The three principles of cardiovascular fitness are Frequency, intensity, and time. If they are not performed properly can lead to injury.

Explanation:

Overload: In order to improve the endurance we need to work a bit harder than our capacity. This is achieved by 3 principles.

If Any of them are not followed properly can lead to injury.

For example,

Therefore, we can say that the three principles of cardiovascular fitness are Frequency, intensity, and time. If they are not performed properly can lead to injury.

The three principles of cardiovascular fitness are progression, overload and specificity.

The principle of progression states that in order to physically improve, the athlete must increase all physical demands constantly, each time push forward. So, if the athlete pushes too ahead, his body would collapse, leading to damages to his cardiovascular system, too much extreme physical pressure will lead to injuries, and if he do it often without measurement, he will seriously injure his physical health.

The principle of overload is part of the principle of progression, this is the part that make improve the athlete by training harder, overload means to run further each day, or run the same distance but going further miles. The consequences in case of too much pressure is similar than the last one. Overloading too mucho the body will lead to injuries. The right way is too know own limits, to know until what limit to push and work harder.

The principle of specificity refers to perform specific training according to the purpose. Also, this specificity means to know weaknesses and train them to improve, that's why specificity also implied progression. Training is not about just doing exercise, but it's knowing what to improve and how, then, the athlete has to focus on that, that's specificity. However, this principle can also lead to injury by being too specific, working out too much a muscle will lead to a collapse or injury, that's why all training routines must be focus in groups of muscle that have to be improve, not just one.

you aren't worthless, you are a one of a kind person who, deserves happiness like anyone else, you may not get it but everyone deserves happiness. i hope this .
