Questions and Answers

When a carbohydrate is metabolized without oxygen, what is it called?

Anaerobic Glycolysis

If length of an activity is greater than 150 seconds, the _____ energy system is probably used.

Aerobic Glycolysis

All three energy systems are used in sports and should be trained and improved for successful sport performance.

Study Notes

Energy Systems

  • Anaerobic Glycolysis occurs when carbohydrates are metabolized without oxygen.
  • If an activity lasts longer than 150 seconds, Aerobic Glycolysis is primarily used.
  • All three energy systems need to be trained for optimal sports performance.

Training Principles

  • The specificity of training principle emphasizes that training should relate to the specific strength and demands of the sport.
  • Task performance can be enhanced through stress followed by relief.
  • Extended periods of poor training indicate potential overtraining.
  • 'Periodization' divides a pre-season into three four-week blocks, starting with an easier week, followed by medium/hard, and culminating in the hardest week.

Off-Season Training

  • Off-season training should focus on general strength and conditioning relevant to the sport by applying the specificity and reversibility principles.

Warm-Up Recommendations

  • An effective warm-up consists of 10-15 minutes of low-intensity activity paired with both static and dynamic stretching.

Growth and Development

  • Both sexes gain weight during adolescence, but this is paired with increases in height.
  • Coaches should recognize maturational variations and allow athletes adjustment periods following significant growth spurts.
  • Males typically begin their growth spurt at age 12, peaking in height by 14, while females begin at 10, reaching peak height by 12.

Nutrition and Hydration

  • Students should consume a high-carbohydrate meal or snack 3 to 4 hours prior to practices and games.
  • A carbohydrate/protein snack should be consumed within 30 minutes after competition or practice for faster recovery.
  • Losing 1-2% of body weight negatively impacts performance.
  • Water constitutes 55-65% of a student's body weight, and students lose water and electrolytes through sweating.

Heat Management and Safety

  • To prevent heat-related illnesses, practice sessions should be shortened or extended breaks provided during hot weather.

Performance-Enhancing Drugs

  • The three main classes of performance-enhancing drugs are stimulants, anabolic steroids, and blood doping.

Injury Management

  • The recommended approach for injury treatment is Rest, Ice, Compression, Elevate (RICE).

Strength Training Effects

  • Strength training positively impacts all tissues in the body.
