NASM Chapter 5 Lab Activity

Number the following events in the order (1 through 5) in which they occur during the sliding filament theory:

• Calcium is then released into the muscle, stimulating a chain of events that results in the myosin heads binding to actin.

• The nerve impulse begins in the CNS and travels down the motor neuron, which is facilitated by sodium and potassium electrolytes, to the neuromuscular junction.

• The myosin heads then pull the actin toward the sarcomere center, which slides the overlapping filaments past each other, shortening the entire muscle.

• The nerve impulse travels into the muscle infrastructure, stimulating a small organ called the sarcoplasmic reticulum to release the electrolyte calcium

• Acetylcholine is released into the neuromuscular junction, which then helps the nerve impulse cross the synapse into the muscle.

⦁ Discuss the difference between a synovial and non-synovial joint. Provide an example for each.

Groups:

(a) Synovial

,

(b) Nonsynovial

Write out one to two SMART goals for each client’s primary fitness goal.

What types of muscle fibers will you focus on during their training? Provide a detailed description and rationale for each client.

What types of exercise will you choose that are related to each client’s goal and targeted muscle fiber type?

If you show them new exercises, what stages of motor skill development will they go through to learn the new skill?
