Question 1

Which muscle is primarily used in a squat?

Accepted Answer

Quadriceps

Answer

The quadriceps femoris is a group of four muscles located on the front of the thigh, including the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. These muscles are primarily responsible for knee extension, which is a key movement during the upward phase of a squat. They also play a crucial role in stabilizing the knee joint throughout the exercise.

Question 2

What is the function of the hamstrings?

Accepted Answer

Flex knee, extend hip

Answer

The hamstrings are a group of three muscles (biceps femoris, semitendinosus, and semimembranosus) located on the back of the thigh. Their primary functions are to flex the knee joint, bringing the heel towards the buttocks, and to extend the hip joint, moving the leg backward. These actions are fundamental in movements like running, jumping, and various lower body exercises.

Question 3

What is ATP's role in exercise?

Accepted Answer

Energy for muscles

Answer

Adenosine triphosphate (ATP) is the primary energy currency of the cell, essential for all cellular activities, including muscle contraction. When ATP is broken down into ADP and a phosphate group, it releases energy that powers muscle fibers to contract. Without a continuous supply of ATP, muscles cannot function, making it critical for any form of exercise.

Question 4

Where is the deltoid muscle located?

Accepted Answer

Shoulder

Answer

The deltoid muscle is a large, triangular muscle that covers the shoulder joint, giving it its rounded contour. It consists of three distinct heads (anterior, lateral, and posterior) that work together to abduct, flex, and extend the arm. This muscle is crucial for a wide range of arm movements and shoulder stability.

Question 5

Which plane divides the body into left and right?

Accepted Answer

Sagittal plane

Answer

The sagittal plane is an imaginary vertical plane that divides the body into right and left halves. Movements that occur within this plane typically involve flexion and extension, such as bicep curls, squats, or walking. Understanding anatomical planes helps in analyzing and describing human movement accurately in exercise science.
