Study Notes
Epidemiology
- Focuses on investigating rates and causes of disease and injury.
- Uses research methods to understand patterns in populations.
- Considers factors like age, race, sex, environment, time of year, and location.
- Identifies risk factors and helps develop assessment and intervention strategies.
Pre-Participation Exam (PPE)
- Important for identifying potential injury risks before a season starts.
- Should be conducted 4-6 weeks before the start of the season.
- Should be conducted annually.
- Includes musculoskeletal evaluation, flexibility, strength & mobility testing, neurological and skin assessments.
Nutrition for Athletes
- Macronutrients (carbs, protein, fats) provide energy, support growth and repair, and maintain muscle.
- Micronutrients (vitamins, minerals, water) regulate body processes.
- Complex carbs are broken down into simple sugars, providing energy and stored as glycogen.
- Fiber aids digestion, reduces risk of colon cancer, obesity, constipation, colitis, and diabetes.
- Protein is essential for growth, maintenance, and repair of tissues, hormone production, and muscle building.
- Fats are a concentrated source of energy, with saturated fats increasing heart disease risk and unsaturated fats decreasing heart disease, stroke, and hypertension.
- Vitamins are essential for various bodily functions, and deficiencies can lead to a range of health issues.
- Minerals are stored in liver and bones, crucial for energy production, bone health, and nerve conduction.
- Water is the most essential nutrient, vital for chemical processes, and dehydration can lead to illness or death.
Principles of Conditioning & Training
- Safety is paramount.
- Warm-up is essential to prevent injuries, enhance performance, and prepare the body for activity.
- Cooldown is crucial to reduce muscle soreness and bring the body back to a resting state.
- Overload & SAID (Specific Adaptation to Imposed Demands) Principle: To improve, one must increase the demands of training.
- Consistency and routine are critical for progress.
- Progression involves gradually increasing the intensity, duration, or frequency of training.
- Intensity refers to the level of effort during training.
- Specificity: Training should be relevant and appropriate for the specific sport.
- Individuality: Training programs should be tailored to each person's needs and abilities.
- Relaxation and stress management are essential for avoiding overtraining and promoting recovery.
Resistance Training Techniques
- Progressive resistance training involves gradually increasing weight or resistance over time.
- Overload principles must be applied to enhance strength.
- Sustaining the same intensity maintains muscle strength.
Overtraining and Under-training
- Overtraining can lead to psychological and physiological breakdown, causing injury, fatigue, and illness.
- Adequate training, nutrition, and rest are essential to prevent overtraining.
- Under-training can lead to muscle atrophy, a decrease in strength, and a reduction in fitness gains.
Flexibility
- Factors limiting flexibility include bone structures, excessive fat, muscle and tendon lengths, connective tissue, skin, and neural tissue tightness.
- Flexibility can be improved through stretching and other exercises.
Amino Acids
- Building blocks of proteins.
- Some are produced by the body, while others are essential and must be consumed through diet.
- Animal products contain all essential amino acids, while plant sources may not.
Protein Functions
- Anabolism (building tissues).

- Unsaturated Fats: Plant derivatives, liquid at room temperature, decrease heart disease, stroke, and hypertension
- Trans Fat: Similar to saturated fat, found in junk foods and fast foods.
- Omega 3: Unsaturated fat found in cold water fish.
Vitamins
- Fat-soluble vitamins (A, D, E, K): Stored in fat and can accumulate in the body.
- Water-soluble vitamins (C, B): Not stored and must be consumed regularly.
- Antioxidants (A, C, E): Protect against aging, cancer, and heart disease.
Mineral Functions
- Stored in liver and bones.
- Examples include iron (energy), magnesium (energy), calcium (bone), sodium, and potassium (nerve conduction).
Water
- Most essential nutrient for all chemical processes.
- Dehydration can lead to illness and death.
- Electrolytes help maintain hydration levels.
Injury Prevention
- Epidemiologists investigate injury and disease rates and their causes.
- Epidemiology studies how injuries, diseases, and health conditions are distributed in populations.
- Epidemiologists believe injuries and illnesses have causes, not just bad luck.
- Rates of injury are influenced by person (age, race, sex), place (environment, surface, population density), and time (season, game stage).
- Epidemiology helps identify risk factors, develop intervention strategies, and promote proper equipment use.
