Study Notes
Risk Mitigation & Management
- Warm-up prepares the body for physical activity, increasing body temperature, heart rate, and blood flow to muscles, enhancing muscle elasticity and activating the central nervous system.
- Cool-down gradually returns the body to a resting state, preventing cardiac abnormalities, dizziness, and fainting by reducing sudden drops in blood pressure and preventing blood pooling in the lower extremities.
-
Stretching and Flexibility
- Static Stretching: increases flexibility, relaxes muscles, but doesn't prepare the body for dynamic movements. Over-stretching can increase the risk of injury.
-
Classification:
- Passive: using another person or a surface for support.
- Static: holding a stretched position.
- Ballistic: using momentum, uncontrolled and jerky movements.
- Dynamic: movement-oriented, improves functional movements used in daily life and sports. Includes Proprioceptive Neuromuscular Facilitation (PNF).
Injury
- Factors contributing to injury: body mechanics, muscle strength, and overall physical condition.
-
Types of Injury:
- Acute: sudden injuries during an activity.
- Chronic: injuries resulting from overuse.
How to Spot an Injury
- Symptoms: deformity, open wounds, tenderness, and swelling.
RICE
- Rest: avoid moving the injured area.
- Ice: applying ice constricts blood vessels, reducing swelling.
- Compress: using an elastic bandage to limit swelling.
- Elevate: raising the injured area to reduce blood flow and swelling.
Common Types of Injury
- Contusion: discoloration without skin breakage.
- Sprain: injury to a joint, damaging connective tissue.
- Strain: muscle injury caused by overextension or overstretching..
- Dislocation: separation of a joint.
- Fracture: break in a bone.
Physical Fitness
- Physical Fitness: characteristics that enable one to perform physical activities; comprised of components (health-related, skill-related, and physiological).
- Cardiorespiratory Endurance: sustaining physical activity, involving the ability of the cardiorespiratory system to supply blood and oxygen to working muscles.
- Musculoskeletal Fitness: muscles' ability to exert maximum force (strength) or persist without fatigue (endurance).
- Response & Adaptation: Short-term changes in the body ("responses") during exercise (e.g., increased heart rate for blood supply to muscles), vs long-term adaptations (e.g., lower resting heart rate).
Training Principles
- Overload: progressively increasing the workload to challenge the body.
- Progression: gradually increasing the intensity, duration, or difficulty of exercise.
- Specificity: tailoring exercise to the desired outcome.
- Reversibility: the body loses the gains achieved from exercise if training is stopped. Maintenance is crucial.
- Variety: changing the exercise routine to prevent boredom and overtraining.
- Individual Differences: recognizing differing responses to exercises.
