The sinoatrial node (SA node), which is sometimes called the pacemaker of the heart, is located in which chamber of the heart?

Select the correct answer(s).

(0/0)

Explanation

The SA node is located on the posterior wall of the right atrium, while the atrioventricular node (AV node) is located on the floor of that same chamber. ACE’s Essentials of Exercise Science for Fitness Professionals, p. 214

Which of the following is NOT a method the body uses to preserve blood volume during steady- state exercise?

Select the correct answer(s).

(0/0)

Explanation

The following changes take place to preserve blood volume: A progressive increase in heart rate at steady-state exercise to maintain cardiac output and offset the small decrease in stroke volume associated with the fluid loss A compensation in blood press

Minute ventilation decreases after an exerciser crosses the second ventilatory threshold (VT2).

Select the correct answer(s).

(0/0)

Explanation

During submaximal exercise, ventilation increases linearly with oxygen consumption and carbon dioxide production. This occurs primarily through an increase in tidal volume (i.e., the volume of air inhaled and exhaled per breath). At higher or near-maximal

What hormone dilates the respiratory passages and reduces digestive activity and bladder emptying during physical activity?

Select the correct answer(s).

(0/0)

Explanation

In addition to its effects on the cardiovascular and metabolic systems, epinephrine dilates the respiratory passages to aid in moving air into and out of the lungs, and reduces digestive activity and bladder emptying during exercise. ACE’s Essentials of E

Which slow-acting hormone stimulates the mobilization of free fatty acids from adipose tissue, mobilizes glucose synthesis in the liver, and decreases the rate of glucose utilization in the cells

Select the correct answer(s).

(0/0)

Explanation

Cortisol is a glucocorticoid released from the adrenal cortex that stimulates free fatty acid (FFA) mobilization from adipose tissue, mobilizes glucose synthesis in the liver (i.e., gluconeogenesis), and decreases the rate of glucose utilization by the ce

What is the only macronutrient whose stored energy generates adenosine triphosphate (ATP) anaerobically?

Select the correct answer(s).

(0/0)

Explanation

Carbohydrate serves as the major food fuel for the metabolic production of adenosine triphosphate (ATP), which is a chemical compound required for all cellular work. Importantly, carbohydrate is the only macronutrient whose stored energy generates ATP ana

What is the primary advantage of the increase in blood volume that results from chronic cardiorespiratory exercise?

Select the correct answer(s).

(0/0)

Explanation

A physical-performance advantage of reduced blood viscosity, which is a direct result of the increased blood volume, is that it enhances oxygen delivery to the active skeletal muscles, because the blood flows more easily through the vessels, including the

During what phase of the general adaptation syndrome will a client see progressive increases in muscle size and strength?

Select the correct answer(s).

(0/0)

Explanation

The adaptation phase, or resistance phase, generally begins around weeks four through six and represents major muscular adaptations (biochemical, mechanical, and structural). This phase is characterized by progressive increases in muscle size and strength

An individual is using a resistance band to perform very short-duration (less than 2 seconds per stretch) hamstring stretches in sets of eight repetitions. What flexibility-training technique is this person using?

Select the correct answer(s).

(0/0)

Explanation

Active isolated stretching follows a design similar to a traditional strength-training workout. Instead of holding stretches for 15 to 30 seconds at a point of resistance (i.e., mild discomfort), stretches are never held for more than two seconds. The str

During what phase of the functional movement and resistance training component of the ACE IFT Model is the application of external resistance to functional movement patterns a primary focus?

Select the correct answer(s).

(0/0)

Explanation

The focus of phase 3, or load training, is on applying external resistances, or loads, to functional movement patterns. Phase 3 applies the traditional resistance-training methodology for endurance, hypertrophy (or strength-endurance), and strength to the

A client who is in the load-training phase of functional movement and resistance training will be working in the anaerobic-endurance training phase of cardiorespiratory training.

Select the correct answer(s).

(0/0)

Explanation

While these two phases both represent phase 3 of their respective training components, it is important to understand that each client will progress from one phase to the next according to his or her unique needs, goals, and available time to commit to tra

It is essential that personal trainers conduct assessments of muscular strength and endurance before a new client begins a stability and mobility training program.

Select the correct answer(s).

(0/0)

Explanation

No assessments of muscular strength or endurance are required prior to designing and implementing an exercise program during this phase. Assessments that should be conducted early in this phase include basic assessments of posture, balance, movement, and

During which phase of the functional movement and resistance training component of the ACE IFT Model should assessments of muscular strength and endurance be introduced?

Select the correct answer(s).

(0/0)

Explanation

During phase 3, or load training, assessments of muscular strength and endurance are introduced to facilitate program design and quantify progress. ACE Personal Trainer Manual, 5th edition, p. 100
