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?
In some fitness exercises you will build muscle mass but do not train the muscle to be effective. What type of training will do that and why do people do these types of trainings?
The stairs excerise is an excellent approach to strengthen the core muscles. It also engages every major muscle in your lower body - glutes, hamstrings, quadriceps, abs, and calves - in exercise, toning and sculpting your physique. Therefore climbing stairs for 2-4 hours daily will build the muscle mass and strength, stamina, endurance and flexibility of the body. But what exactly can do for person strength is that legs only, stamina and endurance and resilience and flexibility what does that mean to get better?

- 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_forwardTwo skeletal muscles A and B contain 1000 and 200 individual muscle fibers respectively. Muscle A has 10 motor units each consisting of one motor neuron and 100 muscle fibers. Muscle B has 20 motor units and each consisting of 10 muscle fibers and one motor neuron. Which muscle can produce a wider range of forces?arrow_forwardIn an isometric contraction the muscle develops tension but does not - exhibit elasticity does not expend energy - lengthen - widen conduct electrical current Nextarrow_forward
- If using stairs excerise is an excellent approach to strengthen the core muscles. It also engages every major muscle in your lower body - glutes, hamstrings, quadriceps, abs, and calves - in exercise, toning and sculpting your physique. Therefore climbing stairs for 2-4 hours daily will build the muscle mass and strength, stamina, endurance and flexibility of the body. But what exactly can do for person strength is that legs only, stamina and endurance and resilience and flexibility what does that mean to get better? I'm talking about ten staircase floor of ten steps each one that should be 200 steps together. So did 2-4hrs daily fir two months what can you get for strengths and more how strong can I lift?arrow_forwardIndicate which of the following are true. Chronically shortened muscles will lose sarcomeres in series in order to maintain ideal amounts of myofilament overlap. Contractile force is proportional to the length of a muscle. Muscle organ contraction is all or nothing. Muscle cells are surrounded by an endomysium. Actin is the thick filament and Z-lines are where the cross-bridges zig-zag to adjacent actin filaments. Muscles with fewer motor units are weaker, i.e., capable of less force. A nerve impulse, calcium, and ATP are necessary for muscle contraction. Tendons attach bones to bones and help to limit the range of motion at joints. Muscle tissue is very dynamic and will respond to chronic stress by becoming stronger (making more myofilaments), chronic contraction by becoming shorter (losing sarcomeres in series), and stretching by becoming longer (adding sarcomeres in series). Myofilaments are actually long strands of proteins.arrow_forwardThe following are the basic steps of a muscle contraction: I. Neurotransmitters bind to receptors II. Myosin pulls on actin III. Ca2+ binds to troponin IV. Myosin binds to actin V. Myosin releases actin VI. Ca2+ is released/unbound Which of the following puts the steps above in the correct order?arrow_forward
- Muscles provide the force for moving body parts.arrow_forwardWhy do previously trained muscles adapt more quickly to retraining after a period of disuse ? I need unique answer, don't copy from Googlearrow_forwardYou are at the gym and doing strength training. You feel in good shape and should try to break personal records in squats. You place the bar on your back and begin to take in, that is, your motor neurons begin to send action potentials through all your motor units to the thigh muscles. What is the contraction called when you a) bend down and b) are in good shape and can generate more force than the bar weighs c) stay standing in one and the same position without being able to push yourself up in a standing position?arrow_forward
- What are the differences in the cellular and molecular levels in a bodybuilder arms muscles compared to those of a weaker, untrained person?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_forwardA motor unit is: A group of muscle cells wrapped in perimysium A group of muscles working in unison A group of muscle cells plus the 1 neuron that innervates them A group of sarcomeres contracting in unisonarrow_forward
