During the descent of a single-leg squat, a client's knee moves inward. which of the following muscles should the trainer recognize as requiring static stretching?

vastus lateralis

Explanation:

Based on the information provided within the question it can be said that in this scenario the trainer should recognize the vastus lateralis as needing static stretching. This is because this muscle's only task is to extend the lower leg and thus allowing the body to lift itself up from a squatting position. Which is exactly what the client is currently doing in this scenario.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.    

the answer is :
