Exercise Science Practice Exam Review (Chapters 1-3)

Comprehensive question-and-answer flashcard set covering foundational concepts, research methods, and energy systems from Chapters 1, 2, and 3 study guides.

How is exercise science defined in Chapter 1?

The scientific study of human movement and the physiological, psychological, and biomechanical responses to physical activity and exercise.

Which era marked the formal emergence of exercise science as a distinct academic discipline?

The mid-to-late 20th century, as physical education graduate programs began separating into science-based disciplines.

What is a primary function of the American College of Sports Medicine (ACSM) founded in $1954$?

Publishing position stands that establish evidence-based guidelines for exercise prescription and health.

How does the textbook distinguish between physical activity and exercise?

Physical activity includes any bodily movement resulting in energy expenditure, while exercise is structured, planned, and intended to improve fitness.

What foundational academic preparation is emphasized for students entering exercise science to support structural fitness and metabolic health?

Coursework in the biological, behavioral, and social sciences paired with practical experience in exercise settings.

What type of research best describes a study evaluating whether a $12\text{-week}$ aerobic training program lowers resting blood pressure in adults with hypertension?

Applied research, because it tests an intervention with a direct practical health application.

How does quantitative research differ from qualitative research?

Quantitative research uses numerical data and statistical analysis, whereas qualitative research explores experiences, meanings, and perspectives.

In a study assessing the effect of high-intensity interval training (HIIT) on $\text{VO}_2\text{max}$, which type of variable does the HIIT protocol represent?

The independent variable.

If a skinfold caliper consistently reads $3\text{ }\text{percent}$ higher than actual body fat every time it is used, how is this measurement instrument characterized?

It is reliable but not valid.

How does a meta-analysis differ from a standard systematic review?

A meta-analysis uses statistical methods to mathematically pool and analyze data from multiple individual studies, whereas a systematic review synthesizes research qualitatively.

What are study requirements called when participants must be between $18$ and $40$ years of age and free of cardiovascular disease?

Inclusion and exclusion criteria.

How do basic research and translational research differ?

Basic research investigates fundamental biological mechanisms, whereas translational research connects basic science findings to practical applications in healthcare or human performance.

In the three-circle model of evidence-based practice, what three components must be integrated?

Best research evidence, clinical expertise, and patient/client values and preferences.

Why must ATP be continuously resynthesized during exercise?

Because the body's stored supply of ATP is limited, so it must be rebuilt rapidly from energy released by breaking down macronutrients.

Which energy pathway is the primary contributor to ATP resynthesis during a $5\text{-second}$ maximal effort like a $40\text{-yard}$ dash?

The immediate energy system, using stored ATP, ADP, and creatine phosphate.

What is the primary metabolic fate of pyruvic acid during high-intensity anaerobic exercise lasting $60\text{ seconds}$?

It is converted into lactic acid (lactate and hydrogen ions) via the enzyme lactate dehydrogenase.

What does a Respiratory Exchange Ratio (RER) value of $1.00$ indicate about substrate utilization?

It indicates $100\text{ }\text{percent}$ carbohydrate utilization.

What is the definition of the maximal lactate steady state (MLSS)?

The highest exercise intensity where lactate production and clearance are in equilibrium over time.

At what approximate exercise intensity does peak fat oxidation typically occur before shifting toward carbohydrate utilization?

At approximately $65\text{ }\text{percent}$ of $\text{VO}_2\text{max}$.
