Why do sedentary ,healthy adults require dietary proteins/amino acids to maintain good health?

• to maintain cellular structure and function

• to prevent diseases such as cancer

c. to strengthen bones - ANS - ANSWER:

• to maintain cellular structure and function

EXPLANATION:

Protein is the primary structural and functional component of every cell in the human body.Dietary proteins are used for growth and development and to build and repair cells; they serve as enzymes, transport carriers, and hormones. Therefore, dietary protein is essential for maintaining health, reproduction, and cellular structure and function. This applies to both active and sedentary individuals.

Which muscle is directly targeted during the pec-deck?

• deltoids

• pectoralis major

c. triceps brachii - ANS - ANSWER:

• pectoralis major

EXPLANATION:

In the pec-deck movement, the idea is to create a long level out of your arms, therefore putting more pressure on the primary and secondary muscles. The pec-deck directly targets the pectoralis major, and does so in a way different than a bench press because the elbows are unlocked throughout the whole range of motion. This length in the arms makes the movement much harder. The deltoids and triceps brachii are assistance muscles, working with the pectoralis major to create the movement.

Which of the following statements is true regarding Golgi tendon organs?

• they are mechanoreceptors located within the musculotendinous junction that are sensitive to

tension and rate of tension change

• they are mechanoreceptors located in joints throughout the fibrous capsule and ligaments that

respond to joint position, movement, and pressure change

• they are major sensory organs that are sensitive to change in length and rate of length change -

ANS - ANSWER:

• they are mechanoreceptors located within the musculotendinous junction that are sensitive to

tension and rate of tension change

EXPLANATION:

Golgitendonorgans (GTOs) are activated when the tendon attached to an active muscle is stretched. As tension increases within a muscle, discharge of the GTOs increases. They inhibit a motor neuron when muscle tension increases, and this inhibition is thought to provide a mechanism that protects against the development of excessive tension.

Which of the following is one of the elements that must exist for a strength and conditioning professional to be found negligent?

• presence of an effect

• presence of ab obligation

c. presence of a duty - ANS - ANSWER:

• presence of a duty

EXPLANATION:

Negligence is a failure to act as a reasonable and prudent person would under similar circumstances. Four elements must exist for negligence to be proven: presence of a duty, breach of duty, proximate cause and damages. To be proven negligent, the professional must have had a duty to act and failed to do so, which is termed a breach of duty. In addition, a professional must act with the appropriate level of care, and failure to do so must have resulted in either physical injury or economic damage because of the natural and continuous sequence of reasonably foreseeable events (approximate cause).

When estimating 1RM for power exercises, what is the maximum number of repetitions one can use for estimation?

• 8

• 5

c. 6 - ANS - ANSWER:

• 5

EXPLANATION:

Power exercises do not lend themselves well to multiple-RM testing above five repetitions for repeated testing sets, because technique can deteriorate quickly. Other types of exercise can use more than five repetitions. Using a 10RM load to predict 1RM is a common method.

Performing warm-up sets prior to performing a 1RM bench press test will increase which of the following test characteristics?

• inter-rater agreement

• validity

c. reliability - ANS - ANSWER:

• reliability

EXPLANATION:

Performing a warm-up before any testing will increase a test's reliability. An appropriately organized warm-up consists of a general warm-up followed by a specific warm-up. Both types of warm-ups include body movements similar to those involved in the test. An organized, instructor-led general warm-up ensures uniformity. It is acceptable to allow two or three activity- specific warm-up trials, depending on the test protocol, and have subsequent trials actually count towards the score. Depending on the test protocol, the score can be the best or the average of the post-warm-up trials.
