Study Notes
Movement Terminology
- Abduction: Movement of arms or legs away from the body in the frontal plane.
- Adduction: Movement of arms or legs closer to the body in the frontal plane.
- Flexion: Decreasing the angle of a joint in the sagittal plane.
- Extension: Increasing the angle of a joint in the sagittal plane.
- Lateral Rotation: Outward rotation of arms or legs in the transverse plane.
- Medial Rotation: Inward rotation of arms or legs in the transverse plane.
Muscle Physiology
- Actin/Myosin: Primary contractile proteins in muscle fibers forming sarcomeres.
- Concentric Contraction: Muscle shortens while under tension.
- Eccentric Contraction: Muscle lengthens while under tension.
- Isometric Contraction: Muscle develops tension without joint movement.
- Sarcomere: Fundamental contractile unit of muscle fibers.
- Types of Muscle Fibers:
- Fast-Twitch Glycolytic (Type 2B): High power output, low endurance (white fibers).
- Fast-Twitch Oxidative/Glycolytic (Type 2A): Moderate power output and endurance (pink fibers).
- Slow-Twitch Oxidative (Type 1): Low power output, high endurance (red fibers).
Aerobic and Anaerobic Concepts
- Aerobic: Processes that occur in the presence of oxygen.
- Anaerobic: Processes that occur without oxygen.
- Lactic Acid: Byproduct of anaerobic metabolism, particularly in type 2B fibers.
Elements of Motivation
- Intrinsic Motivation: Internal desire for physical activity, leading to long-term adherence.
- Extrinsic Motivation: External influences such as music that can motivate individuals.
- Ambivalence: Conflicting feelings towards exercise or fitness.
Movement Patterns
- Closed Chain: Distal aspect stationary while proximal moves.
- Open Chain: Proximal aspect stationary while distal moves.
Structural Components
- Fascicle: Bundles of muscle fibers encased in fascial sheathing.
- Ligament: Connective tissue that connects bone to bone.
- Tendons: Connective tissue that links muscle to bone.
- Hyaline Cartilage: Smooth material covering articulating surfaces of synovial joints.
Breathing and Volume
- Tidal Volume: Total amount of air inhaled during a breath.
Stages of Change in Physical Activity
- Precontemplation Stage: Individuals are inactive and not considering changes.
- Maintenance Stage: Regular physical activity for at least 6 months.
Coaching and Customer Service
- Evocation: Drawing out ideas instead of imposing them during coaching.
- Customer Service - Type A: Follow-up with evidence of results for clients.
Safety and Emergency Preparedness
- Emergency Action Plan (EAP): Written plan to ensure preparedness for emergencies in facilities.
- Liability Insurance: Essential for trainers to protect against litigation.
Proprioception
