NATA-BOC MCQ 2

Question 1

Which muscle is the primary agonist during hip flexion?

Accepted Answer

Iliopsoas

Answer

The iliopsoas (composed of the psoas major and iliacus) is the strongest and primary hip flexor. While the rectus femoris, sartorius, and TFL all assist with hip flexion, the iliopsoas is the dominant agonist.

Question 2

What is the normal resting heart rate range for a healthy adult?

Accepted Answer

60-100 bpm

Answer

The normal resting heart rate for a healthy adult is 60-100 beats per minute. Well-conditioned athletes may have resting heart rates below 60 bpm (sinus bradycardia), which is a normal adaptation to aerobic training.

Question 3

The rotator cuff is composed of four muscles. Which of the following is NOT a rotator cuff muscle?

Accepted Answer

Teres major

Answer

The rotator cuff consists of the supraspinatus, infraspinatus, teres minor, and subscapularis (SITS muscles). The teres major is NOT part of the rotator cuff; it is a separate muscle that assists with shoulder extension, adduction, and internal rotation.

Question 4

During a preparticipation physical examination, an athletic trainer measures an athlete's blood pressure at 152/96 mmHg. How should this reading be classified?

Accepted Answer

Stage 2 hypertension

Answer

According to the American Heart Association guidelines, Stage 2 hypertension is defined as systolic blood pressure of 140 mmHg or higher, or diastolic blood pressure of 90 mmHg or higher. A reading of 152/96 exceeds both thresholds.

Question 5

Which type of muscle contraction occurs when the muscle lengthens while producing force?

Accepted Answer

Eccentric

Answer

An eccentric contraction occurs when a muscle generates force while lengthening. This occurs during deceleration movements, such as lowering a weight or the braking phase of running. Eccentric contractions produce more force than concentric contractions.
