ACTION CPT SCI101 – 85 Exam Questions on Nervous System, Muscles & Energy Systems

This document features 85 carefully curated exam questions with correct answers from Chapter 1 of the ACTION Certified Personal Trainer (CPT) course, course code SCI101. The content is aligned with the 2026 edition of the official "ACTION CPT Study Manual", focusing on foundational knowledge required for certification. The questions comprehensively assess key areas of The Science of Exercise, including: The nervous system (structure and function, neuron anatomy, synaptic transmission) The skeletal system (axial vs. appendicular, joint types and movement, flexibility) The muscular system (muscle types, sarcomeres, muscle actions, motor units) The energy systems of the body (ATP-CP, glycolytic/anaerobic, oxidative/aerobic) Cardiorespiratory physiology (heart anatomy, blood flow, respiratory muscles, oxygen exchange) Exercise response (muscle soreness types, metabolism, training effects) Every question is structured in a Q&A format, making it ideal for self-testing, revision, or preparing for timed exams. The document provides a complete and exam-relevant overview of the most testable concepts in Chapter 1. Relevant for: Students pursuing degrees or certifications in Exercise Science, Kinesiology, Health & Fitness, Sports Science, or Physical Education. Perfect for candidates preparing for ACTION CPT, NASM, ACE, or ISSA certification exams, as well as personal trainers and fitness instructors aiming to reinforce essential anatomy and physiology knowledge.
