Study Notes
Metabolism and Energy Systems
- Anaerobic glycolysis occurs when carbohydrates metabolize without oxygen.
- Aerobic glycolysis is primarily used for activities lasting over 150 seconds.
- All three energy systems (aerobic, anaerobic, and phosphagen) should be trained for optimal sports performance.
Training and Recovery
- Continuing training without rest will not aid faster recovery from viral illnesses (e.g., colds).
- Stress application followed by relief can improve task performance.
- Overtraining can be indicated by a consistent period of poor performance in training or competitions.
Training Periodization
- Periodization involves dividing pre-season into three 4-week blocks, starting with an easy week, then a medium/hard week, and culminating in the hardest week.
- The principle of reversibility states that stopping training can quickly revert strength, fitness, and body composition to pre-training levels within two weeks.
Off-Season Training
- Off-season training should concentrate on general strength and conditioning similar to the primary sport.
Physical Condition and Fatigue
- Inability to execute movements indicates fatigue.
- Effective warm-up includes 10 to 15 minutes of low-intensity activities and both static and dynamic stretching.
Adolescent Development
- Both genders gain weight during adolescence but increasing height is not always accompanied.
- Maturational variation in athletes means recognition of a necessary adjustment period post-growth spurt.
Anabolic Steroids
- Anabolic steroids can cause feminization in boys and masculinization in girls, along with closing growth plates and halting height increases.
Peak Growth Velocity
- Males typically start growth spurts around age 12, peak height velocity by age 14, and taper off by age 16.
- Females usually begin growth spurts around age 10, peak at age 12, and taper off by age 14.
Healthy Nutrition Access for Students
- Strategies to ensure healthy nutrition include offering healthy snacks post-game, providing high-energy food lists, marking water bottle lines for hydration needs, and giving concrete meal recommendations.
Nutritional Timing
- Fueling the body with high-carbohydrate meals/snacks should occur 3 to 4 hours before practices or games.
- Consuming a carbohydrate/protein snack within 30 minutes post-practice accelerates recovery.
Hydration and Performance
- A small protein amount before or after exercise may stimulate muscle repair and growth.
- Losing 1.5% to 2% of body weight negatively impacts athletic performance.
- Water constitutes 55-65% of a student's body weight, and sweating results in the loss of water and electrolytes.
- Strategies to prevent heat-related illnesses include shortening practices or providing more breaks in hot weather.
