What type of muscle contraction is required at the hip during the action of moving from standing to sitting down in a chair? isometric, eccentric or concentric?
What muscles are producing the force at the hip during this movement?
What type of lever is the vastus medialis? Support your answer with a free body diagram.
The vasti muscles are used both for sit-to-stand AND stand-to-sit movements. Which of these two tasks represents a concentric contraction and which represents an eccentric contraction?
Which muscle (vastus lateralis or medialis) do you think is more important for doing a slow, controlled stand-to-sit transition?
If you witnessed your grandfather "plopping" (doing an uncontrolled sit) into a chair, would you recommend giving him eccentric or concentric strengthening exercises for his vasti muscles? Justify your answer.
