  1. THE PHYSIOLOGY OF TRAINING THE DISTANCE RUNNER Dr. Joe Vigil

  2. THE BIOLOGIC LAW OF TRAINING • The structure and performance capability of an organ/organ system is determined by the following: • Its genetic constitution • The quality and quantity of work carried out • The greater the demand/stress placed on an organ within its physiological limits, the more intensely it adapts and the more efficient it becomes.

  3. Physiological Testing Objectives: • Provide baseline information • Provide markers for effectiveness of training • Detect areas of strength/weakness • Optimize performance

  4. Training GoalsMajor Physiological Targets • Improve body’s ability to transport blood and oxygen • Increase ability of specific muscle groups to effectively use available oxygen • Shift blood lactate threshold to higher proportion of maximum speed/power • Increase aerobic capacity • Improve speed • Improve economy

  5. Variables of Endurance Performance • Maximal Oxygen Uptake (VO2 max) • Economy of Motion • Lactate Threshold • Fractional Utilization of VO2 max (%VO2 max) • Fuel Supply

  6. Training Intensities: Lactate Threshold and Training Zones 1. Recovery • Intensity: very low, 2-3 mmol/L below LT, 30-5- bpm below LT • Duration: 30-45 min • Objective: To promote recovery following high intensity intervals or glycogen-depleting overdistance workouts. Maintenance of cardiovascular adaptations and muscle-skeletal system.

  7. Training Intensities: Lactate Threshold and Training Zones 2. Endurance • Intensity: moderate, 1-2 mmol/L below LT, 10-30 bpm below LT • Duration: 30 min- 3hrs • Objective: Develop peripheral training adaptations: increase fat metabolism, increase number of aerobic enzymes, increase size and number of mitochondria, increase capillarization

  8. Training Intensities: Lactate Threshold and Training Zones 3. Lactate Threshold • Intensity: moderate, TEMPO just below LT, or at LT + 5bpm • Duration: TEMPO 20-60 min continuous or LT intervals 5-15 min with equal or one half recovery • Objective: Increase LT (%VO2 max at LT) and maximal aerobic capacity

  9. Training Intensities: Lactate Threshold and Training Zones 4. VO2 max Intervals • Intensity: high, 1-2 mmol/L, above LT, HR associated with 95% VO2max • Duration: 3-5 min intervals with equal amount of rest • Objective: Develop central training adaptations: Increase stroke volume, increase maximal aerobic capacity and lactate tolerance (buffering capacity)

  10. Training Intensities: Lactate Threshold and Training Zones 5. Intensive Repetitions • Intensity: very high, 2-6 mmol/L above LT • Duration: SHORT 30-60 sec with complete recovery. LONG 1-2 min with complete recovery • Objective: Increase anaerobic capacity and buffering capacity

  11. Method of Balke (VO2max) • Walk/Run for 15 min • Convert to meters 1 mile + 1609 meters • Divide by 15 to calculate meters/min • The first 150 meters/min = 33.3 ml VO2 • For every meter under 150, multiply by .178 and subtract from 33.3 ml VO2 • For every meter over 150, multiply by .178 and add to 33.3 ml

  13. The ABC’s of Elite Distance Runners once Aerobic Base has been achieved • Improvement in performance occurs in trained runners when intensity of training is increased • Improvement in Cardiorespiratory fitness occurs when training intensities correspond to 90-100% of VO2 max velocity • Improvement in endurance performance occurs when the intensity in a steady state run does not exceed 4mM lactate concentration, which corresponds to approximately 80-90% VO2 velocity

  14. Major Mechanisms of Optimal Distance Running Performance • Ability to produce high muscle force output at a high velocity for a prolonged period of time • Muscle Fiber Recruitment: Increase number of muscle fibers contracting simultaneously. Increase number of actin/myosin filament in each muscle fiber

  15. Major Mechanisms of Optimal Distance Running Performance • Muscle Fiber Recruitment Rate: Increase rate of repetitive activation of muscle fibers • Mitochondrial Density: Increase number and size of mitochondria around all muscle fibers
