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

Proprioceptor: Neurological devices that detect body position and movement.

Muscle Change Processes

Atrophy/Hypertrophy: Processes of muscle tissue breakdown and building up, respectively.

Characteristics of Individuals

Type B Personality: Responsive, informal, and open interactions.
