Study Notes
Key Concepts in Exercise Science
- Training Effect: Refers to muscular, cardiopulmonary, and metabolic adaptations to exercise.
- Homeostasis: The body's automatic process to maintain a stable internal environment.
- Basal Metabolic Rate (BMR): Measure of the number of calories required to keep your body functioning at rest.
Metabolism and Energy
- Anabolism and Catabolism: Both processes occur simultaneously throughout the body.
- Calorie: Defined as a unit of heat; often measured in kilocalories (kcal) for nutritional purposes.
- Primary Fuel for Endurance: Fatty acids are the main energy source during endurance activities.
- Adenosine Triphosphate (ATP): Key molecule for energy storage and transfer in the body.
Physiological Pathways
- ATP/CP Pathway: Primary pathway utilized for high-intensity activities lasting up to two minutes.
- Element Composition: About 98% of the human body consists of oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
Body Systems Overview
- Respiratory System Functions: Includes oxygen supply, carbon dioxide elimination, and pH regulation.
- Circulatory System Components: Comprises the heart, arteries, and veins.
- Nervous System Structure: Made up of the peripheral and central nervous systems.
Hormonal Functions
- Hormone Classification: Steroids, amino acid derivatives, and peptides are three types of hormones.
- Hemoglobin Role: An important protein in red blood cells facilitating oxygen transport.
- Hormonal Responsibilities: Affect synthesis rates of cellular proteins, enzyme activities, and nutrient transport.
Musculoskeletal System
- Tendons: Connect muscle to bone; distinct from ligaments which connect bone to bone.
- Adult Skeleton: Consists of 206 bones.
- Type I Muscle Fibers: Predominantly aerobic and suited for endurance.
- Type II Muscle Fibers: Not entirely aerobic; designed for explosive strength.
Muscle Contraction Types
- Concentric Contraction: Muscle shortens during contraction.
- Isometric Contraction: Muscle contracts without changing length.
- True Synergy: When one muscle inhibits the action of another muscle.
Movement and Biomechanics
- Flexion: Occurs in the sagittal plane (e.g., bending during a bicep curl).
- Newton's Second Law: Relates to force, mass, and acceleration.
- Biomechanics: Study of movement related to the forces acting on the body.
- Inertia: Divided into resting and moving types.
Levers in Anatomy
- First-Class Lever: Functions like a seesaw, with the fulcrum in the middle.
- Second-Class Lever: Utilizes a load between the fulcrum and the effort.
Body Movements
- Adduction vs. Abduction: Adduction moves a body part toward the midline, not away from it.
- Kinesthesis: Awareness of body position and movement in space.
