- You are training athletes for the 100-meter dash. They need muscles specialized for speed and strength, not endurance. What muscle characteristics would your training regimen aim to develop? How would you alter it to train a long-distance swimmer?arrow_forwardWhy do you think a person is able to perform anaerobic exercise (such as lifting and holding a heavy weight) only briefly but can sustain aerobic exercise (such as walking or swimming) for long periods?

- In a general sense, how do skeletal muscles produce movement?arrow_forwardThe mechanism of contraction in smooth muscle is different from skeletal muscle in that the site of calcium binding differs ATP energizes the sliding process actin and myosin interact by the sliding filament mechanism the trigger for contraction is a rise in intracellular calcium the thick filaments have fewer myosin headsarrow_forwardWhat is the function of calcium in muscle contractions? to bind to troponin and change its interaction with tropomyosin to alter membrane potential causing a depolarization to bind to myosin and allow it to attach to tropomyosin to release ADP from myosinarrow_forward
- Which of the following statements is true regarding muscle contraction? When a muuscle contracts, the sarcomere remains the same size. When a muscle contracts, the H-zone becomes narrower (shortens). When a muscle contracts, the lighter I-band becomes wider. When a muscle contracts, the A-band shortens.arrow_forwardSkeletal muscle will be released in its contracted (rigor) state when: Group of answer choices ATP is hydrolyzed into forming ADP and inorganic phosphate. ATP binds to the myosin head. ADP is dissociated from the myosin head. ATP binds to the actin G-molecule.arrow_forwardWhy is it incorrect to talk about ‘flexing a muscle’?arrow_forward
- Which of the following is NOT correct regarding muscle contraction?
