2024 NSCA CSCS Final Exam GRADED A+ (ACTUAL EXAM ) Questions and Answers (Solved)

Document Content and Description Below

1. What energy system is most active during brief intense muscular contrac-tions? a. Anaerobic glycolysis b. Phosphagen system c. Aerobic glycolysis d. Gluconeogenesis Answer: B: Phosphagen syste... m The phosphagen system relies on the hydrolysis of ATP from local muscle stores, as well as on the breakdown of creatine phosphate. This system is active during boutsof intense, brief exercise that includes heavy resistance exercises and short intense sprints. This system is active during all activities at eh outset, but is active for a short time before other systems become the predominant energy resource depending on duration of exercise. 2. What determines the energy systems used during a training session? a. Loading intensity b. Injury history c. Session duration d. Athlete's training capacity Answer: C: Session duration The duration, or total training time, will determine the energy systems utilized during a training session. The body's ability to use multiple energy systems to meet the specific needs of an individual fall within a finite time frame for each system, e.g., the phosphagen system persists for approximately six to eight seconds, while aerobic glycolysis can produce energy for several hours. 3. Name the phenomenon that causes increased oxygen usage after an in-tense bout of exercise. a. Post-exercise oxygen consumption b. Excess post-exercise consumption c. Excess post-intense-exercise consumption d. Excess oxygen consumption Answer: B: Excess post-exercise consumption Excess post-exercise consumption refers to the increased rate of oxygen above rest-ing rates after an intense bout of exercise. This increased oxygen need post-training session causes an increased metabolic demand that causes a significant increase in the resting metabolic rate for six to twelve hours post training session [Show More]
