Summary Introduction
To review:
The rationale behind the thinking that muscles do not actively push the weight up during leg presses.
Introduction:
Muscles create movements or resist movement depending on their location and the task. The primary action of the muscles is a contraction. When the skeletal muscles contract, they pull the bone attached to them, while the joint acts as a lever. The movement of the bones creates displacement and the work is done. However, the muscles also oppose the movements.

You and your friend are doing leg presses in the gym one day. As you extend your legs, the stack of weights goes up, and when you bend your legs, the stack goes down. Your friend says your muscles are actively pushing the weights up. Explain to him where he is wrong in his thinking
You are at the gym and doing strength training. You feel in good shape and decided to try to break your personal records in squats. You place the bar on your back and begin to push down, that is, your motor neurons that begins to send action potentials through all your motor units to the quad muscles.
1. What is the contraction called when you
a) bend down
b) are in good shape and can generate more force than what the bar weighs
c) stay standing in one and the same position without being able to push yourself up while standing?

- Which of the following statements is true? Muscles push on bones; they do not pull The end of the muscle attached to the bone that moves least is the origin The end of the muscle that attaches to the bone that moves the most is the antagonist The synergist is the the muscle that opposes the primary movementarrow_forwardJason is a 21-year old university student presenting with pain in the back of his right thigh. The pain started yesterday during soccer game. Jason went to kick the ball and felt an immediate ‘pull’ in the back of his right upper thigh. He had to limp off the field and reported mild pain in his right hamstring muscles with most active movements involving knee flexion and extension. Jason can still walk around without too much discomfort. A muscle is strained or torn when excessive tension or tensile forces within the muscle cause muscle fibres and their surrounding connective tissues to fail. What type of muscle contraction is known to produce the most tension and contribute more to cellular damage? What is the most likely cause of Jason’s pain? Suggest what type of injury Jason has sustained and discuss what structures are typically damaged in muscle strain?arrow_forwardDescribe each muscle needed to contract for specific movement and each muscles action during that action. Each muscle firing is it's own step. Something simple like kicking a ball is one action with multiple muscles firing it that action. You need at least 5 muscles involved in your action Example: Description: Picking up a glass of water. Muscles: Biceps, brachialis. Step 1: The brachialis has an origin at the humerus and inserts at the ulna. Contracting is a flexion action. Example: The [Muscle] has an origin at the [Bone] and inserts at the [Bone]. Contracting is a [Action] actionarrow_forward
- Think about a patient seated in a wheelchair (paraplegic) who must use his/her upper extremities to press down to lift his/her body from a seated position to transfer. What muscles would be involved in this movement (pressing down onto the support surface to lift the body, NOT the full transfer) for the patient to safely lift and support his/her body weight during the movement?arrow_forwardWhich of the following statements are true? Multiple Choice Muscles work in antagonistic pairs because if one muscle shortens during contraction, the opposing muscle across the joint must relax. Muscles work in antagonistic pairs because tendons lengthen during contraction. Muscles work in antagonistic pairs because muscles lengthen during contraction. Muscles work in antagonistic pairs because if one muscle pushes during contraction, the opposing muscle across the joint must pull.arrow_forward"If you step on a sharp object, you flex your leg to avoid the danger. At the same time, your other leg is extended so that you don’t fall off. This method of coordinating muscle contraction so as to prevent muscles from working against each other is called" flexor withdrawal reciprocal inhibition tendon reflex spinal cordarrow_forward
- Which of the following is NOT true of an eccentric contraction? Contraction produces a greater force than a concentric contraction. Contraction is used as an acceleration activity. Muscle attachments move farther apart. Movement occurs with gravity.arrow_forwardWhich of the following best describes rigidity? It affects only antigravity muscles It causes flaccid paralysis It occurs in an upper motor neuron lesion It affects both gravity and antigravity musclesarrow_forwardThe muscle contractions required to maintain balance and posture while moving would be considered: voluntary (planned) movements. rhythmic movements. reflex movements. glacial movements.arrow_forward
- Three physiology students are arguing about ATP and muscle function. Tom says ATP is needed for contraction, not relaxation. Wendy says no, it is needed for relaxation, not contraction. Andrew says he thinks it is needed for both contraction and relaxation. Which of them is right and why?arrow_forwardthe muscle that is "mainly" responsible for a movement is called the? the muscle that acts in opposition of the movement is called the? what two terms describe a body temp either above or below normal? the muscular function of maintaining posture is possible due to what type of contraction?arrow_forwardWhich of the following does NOT describe treppe? It is also referred to as the "staircase" effect. An increase in stimulus intensity is required to see the effect. An incremental increase in force occurs. A period of relaxation can be seen on the muscle twitch tracing.arrow_forward
