Explain how a thorough understanding of anatomy and physiology will help you achieve the following fitness instructor duties. Fitness Instructor Duty How knowledge of anatomy and physiology will assist you Interpret pre-exercise screening information Develop exercise programs suitable for different ages, gender, or fitness levels Provide instructions about exercise technique Explain to clients the purpose of chosen exercises Question 1.2 Complete the following tables to describe the muscle roles, joint movements, and plane of movement during the squat and shoulder press. Squat Muscle Role during the Squat (prime mover, synergist, antagonist, fixator) Abdominals Hip Flexors Quadriceps Gluteus Maximus Joint Concentric (lifting/shortening phase) Eccentric (lowering/lengthening phase) Ankle Knee Hip Plane of Movement (sagittal, frontal/coronal, or horizontal/transverse) Shoulder Press Muscle Role during the Shoulder Press (prime mover, synergist, antagonist, fixator) Rotator Cuff Latissimus Dorsi Triceps Brachii Deltoid Joint Concentric (lifting/shortening phase) Eccentric (lowering/lengthening phase) Shoulder Elbow Plane of Movement (sagittal, frontal/coronal, or horizontal/transverse) Question 1.3 The body undergoes responses to help keep up with increased demand during exercise. The body also undergoes various changes from exercise over a long period of time. Provide one expected short term (during exercise) and long term response to exercise across the below body systems/components. For each body system/component, identify any variances between males and females. Body System/Component Short-Term Response Long-Term Response Neuromuscular & Muscular Systems Variances between males and females Blood Pressure Variances between males and females Cardiovascular System and Cardiorespiratory Fitness (CRF) Variances between males and females Skeletal System (Bones and Joints) Variances between males and females Question 1.4 Complete the table below about cardiovascular circulation and responses. a. Describe the flow of blood in each circulation pathway. b. Outline the three main roles of the blood in the body. c. Describe the effect of exercise intensity on breathing rate and heart rate. a. Circulation Pathways Circulation Pathway Description of Blood Flow in Pathway Pulmonary Circulation Systemic Circulation b. Roles of Blood - Outline the three main roles of the blood in the body. c. Relationship of Exercise Intensity to Breathing Rate and Heart Rate Description of How Exercise Intensity Affects Each Breathing Rate Heart Rate Question 1.5 a. Describe the structure and function of the muscle system, types of muscle tissue and classifications and when applicable, state whether there are any variances between males and females  if there are none, please state this. Structure and function Types of muscle tissue and classifications, e.g., voluntary/involuntary, striped/striated, etc. b. Describe the function of the two muscle proprioceptors below. Muscle Spindle Tendon Stretch Organ (GTO) c. Describe the structure and overall function of the skeletal system, name the major bones, joints, and joint structures and provide bony landmarks. Structure and function Major Bones & Bony Landmarks Major Joints and Joint Structures Question 1.6 As we age, the muscular and skeletal systems undergo changes. In the table below, identify how the following systems change with aging including any differences between males and females. Muscular System Skeletal System
