NFPA Personal Trainer Certification Written Examination A muscle has the capability of receiving and responding to various stimuli. It may respond to a nerve impulse, an electrical stimulus applied directly to the surface of the muscle or to a sharp blow to the muscle or one of its tendons. This characteristic is known as 1. The contractile proteins found within the thin and thick myofilments of skeletal muscle include 2. 3. With a contraction, the muscle shortens as the weight is moved against the contraction, force of gravity; therefore, the positive is accomplished. With a the muscle lengthens as wcight is move in the direction of the force of gravity; under these circumstances, gravity rather than muscle contraction is the force responsible for the movemcnt 4. A point on a limb closer to the trunk is called: 5. Kncc cxtensions are performed in which movement planes? 6. RICE refers to: 7. Normal hyperextension occurs in which joints? 8. The muscle primarily responsible for a particular movement is called a (an) A daily intake of 2500 calories that is composed of 30% fat provides the following number of fat grams: 9. 10. Which muscle is the Primary mover in shoulder flexion?Explanation / Answer
1. Excitability is one of the characteristics of muscle fibre.
2. Thin one is Actin and thick one is myosin myofilaments.
3. Sarcomere contraction, eccentric contraction
4. Proximal region.
5. A sagittal plane is used for knee extension
6. RICE refers to Rest Ice Compression Elevation.
7. Hyperextension occurs in knee or elbow joints.
8. Smooth muscles are responsible for particular movements in the body.
9. 2500 X 30/100 = 750. Now there are 9 calories in a gram of fat so we divide the number of calories by 9.
Then, 750/9 = 83 grams.
10. The deltoid muscle is the prime mover in the shoulder region.
