SECTION 1: SPORT SCIENCE FOUNDATIONS
Q1. What is the primary role of the NSCA Certified Performance and Sport
Scientist (CPSS)?
A. To prescribe medications for injured athletes B. To serve as the primary rehabilitation
specialist C. To apply sport science knowledge to enhance athlete performance and
well-being D. To replace the strength and conditioning coach in all performance settings
E. To focus exclusively on nutritional planning for athletic teams
CORRECT ANSWER: C. To apply sport science knowledge to enhance
athlete performance and well-being RATIONALE: The CPSS credential is
designed for professionals who apply multidisciplinary sport science—including
physiology, biomechanics, nutrition, and psychology—to optimize athletic performance
and health outcomes across all levels.
,Q2. Which energy system primarily fuels activities lasting 10 seconds or less?
A. Oxidative phosphorylation B. Glycolysis C. Beta-oxidation D. Phosphagen system
(ATP-PCr) E. Krebs cycle
CORRECT ANSWER: D. Phosphagen system (ATP-PCr)
RATIONALE: The phosphagen system provides immediate energy through the
rapid breakdown of stored ATP and phosphocreatine (PCr). It fuels maximal-intensity
efforts such as short sprints and explosive lifts lasting approximately 0–10 seconds.
Q3. The concept of "Long-Term Athlete Development" (LTAD) was primarily
developed by which researcher?
A. Tudor Bompa B. Istvan Balyi C. Hans Selye D. Vladimir Zatsiorsky E. Mel Siff
CORRECT ANSWER: B. Istvan Balyi RATIONALE: Istvan Balyi is the
primary architect of the LTAD framework, which provides a stage-based model guiding
the physical, technical, tactical, and psychological development of athletes from
childhood through retirement.
Q4. In sport science, what does GPS technology primarily measure in team sport
athletes?
A. Heart rate variability and recovery status B. Muscle oxygenation levels C. External
load metrics such as distance covered and speed D. Internal physiological stress
markers E. Hormonal responses to training
CORRECT ANSWER: C. External load metrics such as distance covered
and speed RATIONALE: GPS (Global Positioning System) units track
positional data to quantify external load metrics including total distance, sprint distance,
velocity zones, accelerations, and decelerations. They do not directly measure
physiological (internal) responses.
Q5. Which of the following best describes "athlete monitoring"?
A. The process of evaluating only injury occurrence B. Systematic collection and
analysis of data to manage training load and athlete performance C. Observational
analysis of technique during competition D. Psychological profiling of athletes E.
Financial tracking of athlete contracts
, CORRECT ANSWER: B. Systematic collection and analysis of data to
manage training load and athlete performance RATIONALE: Athlete
monitoring is the ongoing, systematic collection and interpretation of physiological,
mechanical, and psychological data to inform training decisions, optimize performance,
and reduce injury risk.
Q6. The General Adaptation Syndrome (GAS) was first described by:
A. Tudor Bompa B. Vladimir Zatsiorsky C. Hans Selye D. Yuri Verkhoshansky E. Roger
Enoka
CORRECT ANSWER: C. Hans Selye RATIONALE: Hans Selye (1956)
described the General Adaptation Syndrome, a three-stage physiological response to
stress consisting of the alarm reaction, resistance stage, and exhaustion stage. This
forms the biological foundation for training theory.
Q7. Which of the following is an example of an EXTERNAL load metric?
A. Heart rate B. Rating of perceived exertion (RPE) C. Session distance covered D.
Blood lactate concentration E. Cortisol levels
CORRECT ANSWER: C. Session distance covered RATIONALE:
External load refers to the physical work performed by the athlete, independent of
internal physiological responses. Examples include distance, speed, power output, and
jump counts. Internal load measures include heart rate, RPE, and blood lactate.
Q8. What does the Acute:Chronic Workload Ratio (ACWR) compare?
A. Maximum effort to average effort B. Weekly training load to monthly training load C.
The most recent week's load to the rolling average of the preceding 3–4 weeks D.
Internal load to external load E. Pre-season load to in-season load
CORRECT ANSWER: C. The most recent week's load to the rolling average
of the preceding 3–4 weeks RATIONALE: The ACWR compares an athlete's
acute (recent, typically 7-day) workload to their chronic (longer-term, typically 28-day
rolling average) workload. It provides a snapshot of the athlete's current training load
relative to their prepared fitness base.
, Q9. Which ACWR zone is generally associated with INCREASED injury risk?
A. 0.5–0.8 B. 0.8–1.0 C. 1.0–1.3 D. Above 1.5 E. Below 0.5
CORRECT ANSWER: D. Above 1.5 RATIONALE: An ACWR above 1.5
(sometimes referred to as the "danger zone") represents a spike in acute load that
substantially exceeds the chronic fitness base, which has been associated with elevated
injury risk in team sport research. Ratios of 0.8–1.3 represent the "sweet spot."
Q10. "Supercompensation" refers to:
A. Overtraining syndrome leading to performance decrements B. A period of elevated
performance capacity following training and recovery C. The use of ergogenic aids to
boost performance D. Training volumes exceeding competition demands E.
Simultaneous development of all physical qualities
CORRECT ANSWER: B. A period of elevated performance capacity
following training and recovery RATIONALE: Supercompensation is the
phase following training stress and recovery where the body adapts beyond its previous
baseline, resulting in a temporary elevation in performance capacity. Training must be
timed to capitalize on this window.
Q11. Which of the following best describes "periodization"?
A. Random variation of training stimuli to prevent adaptation B. The systematic planning
and sequencing of training to optimize performance and achieve a competitive peak C.
The use of multiple training modalities without structure D. Exclusively linear
progression of training volume E. Sport-specific skill training without physical
conditioning
CORRECT ANSWER: B. The systematic planning and sequencing of
training to optimize performance and achieve a competitive peak
RATIONALE: Periodization is the deliberate, structured organization of training over
time using varying cycles of volume, intensity, and specificity to produce peak
performance at targeted competitions while managing fatigue and injury risk.
Q12. In Long-Term Athlete Development, the "FUNdamentals" stage focuses on:
