  • Aerobic Examples:

    • Extend distance covered, enhance speed, or increase uphill training

  • Strength Examples:

    • Add more weight, increase repetitions/sets, or shorten rest intervals between sets

Training Thresholds

  • Importance: Identifying specific zones required to stimulate performance improvement.

  • Aerobic Threshold:

    • 65-70% of maximum heart rate (MHR), optimizing aerobic capacity

  • Anaerobic Threshold:

    • 80-85% of MHR, enhancing anaerobic capacity

  • Strength Training Repetition Maximums (RM):

    • 1-6 RM indicates maximal strength development

    • 8-12 RM targets hypertrophy

    • 12-15 RM focuses on muscular endurance

Specificity

  • Definition: Matching training regimens closely with the demands of the specific sport concerning muscle engagement, movement patterns, energy systems used, required speed, and environmental factors.

  • Examples:

    • Cyclists train specifically with bikes

    • Sprinters include explosive lifts in their training

    • Rowers utilize rowing ergometers to maintain sport-specific conditioning

Variety

  • Purpose: Keeps training sessions engaging and mitigates the risk of plateaus in performance and adaptation.

  • Examples:

    • Incorporate diverse exercises, swap equipment, or explore different running terrains

Reversibility

  • Principle: Indicates that fitness levels will diminish rapidly when regular training is ceased.

  • Observed Decline Rates:

    • Aerobic fitness typically declines fastest (within 1-2 weeks)

    • Strength declines more gradually

    • Elite athletes often lose adaptations quicker as they begin from higher baseline levels of fitness

Warm-Up + Cool-Down

Warm-up

  • Objectives:

    • Increase heart rate, body temperature, and blood flow

    • Enhance joint mobility

    • Prepare the body for upcoming movement/speed activities

Cool-down

  • Objectives:

    • Facilitate waste product removal from the body

    • Prevent blood from pooling in extremities

    • Aid in recovery and decrease muscle soreness

  • Examples of Warm-Up Procedures:

    • Aerobic approach: Light jog followed by dynamic stretches; conclude with walking and static stretches

    • Strength approach: Start with warm-up sets before transitioning to static stretching post-exercise

Physiological Adaptations to Training

Definition and Nature of Adaptations

  • Physiological adaptations are changes observed after approximately 6-8 weeks of continuous training, resulting in an enhanced ability to train over longer durations at higher intensities.

Types of Training

  • Aerobic Training: Requires oxygen, associated with enhancing endurance capabilities.

  • Anaerobic Training: Involves high-intensity energy expenditure without oxygen.

  • Resistance Training: Focuses on building strength capacities and muscular endurance.

Factors Influencing Adaptations

Effects of Physiological Adaptations on Performance

  • Heart Rate:

    • Decreased resting and submaximal heart rates, enhancing recovery rates leading to improved overall efficiency and reduced fatigue onset.

  • Stroke Volume & Cardiac Output:

    • Increased amount of blood pumped per heartbeat per minute, leading to more efficient oxygen delivery to working muscles, allowing for sustained higher intensities.

  • Oxygen Uptake (VO₂ max):

    • Increased VO₂ max levels, resulting in better endurance performance and delayed onset of anaerobic metabolism.

  • Haemoglobin Levels:

    • Increased levels of red blood cells and hemoglobin augment oxygen transport capacity.

  • Fats: Major fuel source used during rest or low-intensity activities.

  • Proteins: Vital for growth and muscular repair.

Glycemic Index (GI) Considerations

  • Low GI Foods: Release energy slowly, ideal for endurance-based training.

  • High GI Foods: Rapid energy release, suitable for immediate energy needs.

Hydration

  • Effects of Dehydration: Reduced performance through diminished plasma volume and subsequent stroke volume leading to increased fatigue.

  • Fluid Intake Recommendations:

    • Pre-event: Proper hydration well before activities

    • During event: Aim for approximated 200ml every 15 minutes

    • Post-event: Replace 150% of fluid loss incurred during activity

Dietary Strategies

  • Pre-event Nutrition: Complex carbohydrate intake 3-4 hours prior to exercise.

  • During Event Nutrition: Sugars to maintain stable glucose levels during activity.

  • Post-event Nutrition: Carbohydrates to replenish glycogen stores; protein intake for muscular repair.

  • Carb Loading: Strategic increase in carbohydrate intake to enhance glycogen reserves for endurance events.

Fatigue Factors

  • Anaerobic Fatigue: Results from ATP/phosphocreatine depletion and lactic acid buildup.

  • Aerobic Fatigue: Linked to glycogen depletion leading to performance decline.

Micronutrients

  • Vitamins & Minerals: Essential for energy production, supporting immune function, bone health, and facilitating oxygen transport in the body.

Supplementation

  • Protein Supplements: Aid muscle repair but carry risks of kidney strain if excessively consumed.

  • Caffeine: Enhances alertness and decreases perceived exertion but may lead to dehydration and anxiety if overused.

  • Creatine: Effective in increasing power output and ATP supply for high-intensity performance but may result in weight gain and cramping issues.
