Question 1

Which body fat distribution pattern is most commonly associated with an increased risk of metabolic disease?

Accepted Answer

Android body fat distribution, also known as apple-shaped, is most commonly associated with an increased risk of metabolic disease. This is characterized by excess visceral fat around the abdomen, which can lead to insulin resistance, type 2 diabetes, and heart disease. Gynoid body fat distribution, or pear-shaped, is associated with a lower risk of metabolic disease as the fat is mainly stored in the hips and thighs. Ectomorph and mesomorph are not specific body fat distribution patterns but are rather body type classifications based on overall physique.

Question 2

What action is produced by the quadriceps femora muscles during the concentric phase of the back squat exercise?

Accepted Answer

During the concentric phase of the back squat exercise, the quadriceps femora muscles are responsible for knee extension, which is the straightening of the knee joint as the body moves upward. This is the primary action produced by the quadriceps muscles during the back squat exercise.

Question 3

Which statement is not an American College of Sports Medicine guideline for aerobic exercise and the older adult?

Accepted Answer

The American College of Sports Medicine recommends moderate intensity exercise on most days of the week for aerobic exercise and the older adult. They also recommend initially increasing exercise duration rather than intensity, and note that intensity guidelines established for younger people may not be applicable to older adults. The statement that exercise must be vigorous and continuous to be beneficial is not a guideline recommended by ACSM for older adults.

Question 4

Muscular balance in a resistance training session may be achieved by alternating ______.

Accepted Answer

Muscular balance is achieved by working opposing muscle groups. Leg extensions target the quadriceps, while leg curls target the hamstrings, providing balance between the front and back of the thighs.

Question 5

During your initial assessment of your client, you notice her resting heart rate is 45 beats per minute, while asymptomatic and not taking any medication.  Based on this information, what best describes the heart rate?

Accepted Answer

A resting heart rate of 45 beats per minute is considered bradycardia, which means a heart rate that is slower than normal. Normal resting heart rate ranges from 60-100 beats per minute.

Question 6

Which muscles are used to flex the knee joint?

Accepted Answer

The primary muscles responsible for flexing the knee joint are the hamstrings, gracilis, and sartorius. The hamstrings include the biceps femoris, semitendinosus, and semimembranosus, which are the main muscles involved in knee flexion.

Question 7

Your client reports that she drank a 20 oz. (590 mL) cup of coffee 20 minutes prior to her exercise session.  How might this affect her heart rate and blood pressure responses?

Accepted Answer

Consuming caffeine, which is found in coffee, can increase heart rate and blood pressure due to its stimulant effect on the body. Therefore, drinking a cup of coffee prior to exercise could potentially result in an increase in both heart rate and blood pressure responses.

Question 8

What is the order of "normal" electrical conduction of the heart?

Accepted Answer

The normal electrical conduction of the heart starts with the sinoatrial (SA) node, which is the natural pacemaker of the heart. From there, the impulse travels to the atrioventricular (AV) node, which acts as a gatekeeper, delaying the impulse slightly to allow for ventricular filling. The impulse then travels down the Bundle of His, which divides into the left and right bundle branches and finally, the Purkinje fibers, which spread the electrical signal throughout the ventricles, causing them to contract. This order ensures efficient and synchronized contraction of the heart muscles.

Question 9

Which is most associated with proprioceptive neuromuscular facilitation?

Accepted Answer

Proprioceptive neuromuscular facilitation (PNF) is a type of stretching technique that involves contracting and relaxing muscles before stretching them. PNF is used to increase range of motion and flexibility, and is commonly used in physical therapy and athletic training.

Question 10

When considering the acute responses of arm versus leg exercise, which is true?

Accepted Answer

The answer of When considering the acute responses of arm...

Question 11

What is a potential side effect of taking diet pills prior to an exercise session?

Accepted Answer

Diet pills often contain stimulants such as caffeine or ephedrine which can increase blood pressure and heart rate. This can be dangerous during exercise and increase the risk of heart attack or stroke.

Question 12

What is tachycardia?

Accepted Answer

Tachycardia is defined as a heart rate greater than 100 beats per minute.

Question 13

Your new client is a 42 year old male who is a stock broker. His health history revealed the following: total cholesterol 185 mg/dL (4.7 mmol/L), HDL 32 mg/dL (0.8 mmol/L), LDL 110 mg/dL (2.8 mmol/L), resting blood pressure 138/80 mm Hg, waist circumference 98 centimeters. Based on the client's initial risk classification, what is the most appropriate suggestion for the client regarding his exercise program?

Accepted Answer

The answer of Your new client is a 42 year...

Question 14

The ______ is the muscle responsible for inspiration during quiet breathing.

Accepted Answer

The diaphragm is the primary muscle responsible for inspiration during quiet breathing. The external intercostals also play a role, but to a lesser extent. The internal intercostals and rectus abdominus are not involved in inspiration during quiet breathing.

Question 15

What acute cardiovascular responses accompany the transition from sitting to walking?

Accepted Answer

When transitioning from sitting to walking, the body requires more oxygen, leading to an increase in cardiac output and arteriovenous oxygen difference to meet the increased metabolic demands.

Question 16

What is bradycardia?

Accepted Answer

Bradycardia is defined as a heart rate less than 60 beats per minute.

Question 17

What is the ACSM recommendation for an effective strength training program for a menopausal client?

Accepted Answer

The ACSM recommends a strength training program for menopausal women that includes 10-15 repetitions per set of moderate to vigorous intensity for 8-10 major muscle groups. This will help improve muscular strength, endurance, and bone density, which can decline during menopause. It is also important to incorporate exercises that target the lower back, hips, and wrists to help prevent common injuries and functional limitations that can occur during this stage of life.

Question 18

Which structure is responsible for maintaining atrio-ventricular valve closure in the heart?

Accepted Answer

The papillary muscles are located in the ventricles of the heart and are connected to the atrio-ventricular valves (mitral and tricuspid valves) via chordae tendineae. When the ventricles contract, the papillary muscles contract as well, pulling on the chordae tendineae and preventing the valves from prolapsing into the atria. Therefore, the papillary muscles are responsible for maintaining atrio-ventricular valve closure in the heart.

Question 19

Proper spotting technique for the forward step lunge when using a barbell involves positioning yourself ______.

Accepted Answer

The spotter should be positioned behind the client to provide support if balance becomes compromised.

Question 20

A 57 year old sedentary female client who has a blood pressure of 150/70 mm Hg and a total serum cholesterol of 240 mg/dL (6.2 mmol/L) desires to begin a vigorous intensity exercise program.  How should the personal trainer advise the client?

Accepted Answer

The client has risk factors such as high blood pressure and high cholesterol, and is sedentary. It is advisable to start with a low intensity program and obtain medical clearance before engaging in vigorous exercise.
