4. Section Outline Factors Related to Aerobic Endurance Performance –Maximal Aerobic Power –Lactate (Anaerobic) Threshold –Exercise Economy

5. Factors Related to Aerobic Endurance Performance Maximal Aerobic Power –As the duration of an aerobic endurance event increases, so does the proportion of the total energy that must be supplied by aerobic metabolism. –There is a high correlation between VO 2 max and performance in aerobic endurance events..

6. Factors Related to Aerobic Endurance Performance Lactate (Anaerobic) Threshold –In aerobic endurance events, the best competitor among athletes with similar VO 2 max values is typically the person who can sustain aerobic energy production at the highest percentage of his or her VO 2 max without accumulating large amounts of lactic acid in the muscle and blood...

7. Key Term lactate threshold: The speed of movement or the percentage of VO 2 max at which a specific blood lactate concentration is observed or the point at which blood lactate concentration begins to increase above resting levels. Usually the point where the body switches from predominantly using the aerobic to the anaerobic energy system.

8. Factors Related to Aerobic Endurance Performance Exercise Economy –A measure of the energy cost of activity at a given exercise velocity is referred to as the exercise economy. –An improvement in exercise economy can enhance maximal aerobic power (VO 2 max) and lactate threshold..

9. Section Outline Designing an Aerobic Endurance Program –Step 1: Exercise Mode –Step 2: Training Frequency –Step 3: Training Intensity Heart Rate Ratings of Perceived Exertion Metabolic Equivalents Power Measurement –Step 4: Exercise Duration –Step 5: Exercise Progression

10. Designing an Aerobic Endurance Program Step 1: Exercise Mode –Exercise mode is the specific activity performed by the athlete: cycling, running, swimming, and so on. –Remember that the more specific the training mode is to the sport, the greater the improvement in performance. (Specificity)

11. Designing an Aerobic Endurance Program Step 2: Training Frequency –Training frequency is the number of training sessions conducted per day or per week. –The frequency of training sessions will depend on the interaction of exercise intensity and duration, the training status of the athlete, and the specific sport season.

12. Designing an Aerobic Endurance Program Step 3: Training Intensity –Adaptations in the body are specific to the intensity of the training session. –High-intensity aerobic exercise increases cardio-vascular and respiratory function and allows for improved oxygen delivery to the working muscles. –Increasing exercise intensity may also benefit skeletal muscle adaptations by affecting muscle fiber recruitment.

13. Designing an Aerobic Endurance Program Step 3: Training Intensity –Heart Rate The most frequently used method for prescribing aerobic exercise intensity

14. Table 18.1

15. Designing an Aerobic Endurance Program Target Heart Rate Calculations –Karvonen Method Age-predicted maximum heart rate (APMHR) = 220 – age Heart rate reserve (HRR) = APMHR – resting heart rate (RHR) Target heart rate (THR) = (HRR × exercise intensity) + RHR Do this calculation twice to determine the target heart rate range (THRR).

16. Designing an Aerobic Endurance Program Target Heart Rate Calculations –Percentage of Maximal Heart Rate Method Age-predicted maximum heart rate (APMHR) = 220 − age Target heart rate (THR) = (APMHR × exercise intensity) Do this calculation twice to determine the target heart rate range (THRR).

17. Designing an Aerobic Endurance Program Step 3: Training Intensity –Ratings of Perceived Exertion Can be used to regulate intensity of aerobic endurance training across changes in fitness level Typically uses the 15-point Borg scale May be influenced by external environmental factors

19. Designing an Aerobic Endurance Program Step 4: Exercise Duration –Exercise duration is the length of time of the training session.

20. Key Point The duration of a training session is often influenced by the exercise intensity: the longer the exercise duration, the lower the exercise intensity.

21. Designing an Aerobic Endurance Program Step 5: Exercise Progression –Progression of an aerobic endurance program involves increasing the frequency, intensity, and duration. –Frequency, intensity, or duration should not increase by more than 10% each week. –When it is not feasible to increase frequency or duration, progression can occur with intensity manipulation. –Progression of intensity should be monitored to prevent overtraining.

22. Section Outline Types of Aerobic Endurance Training Programs –Long, Slow Distance Training –Pace/Tempo Training –Interval Training –Repetition Training –Fartlek Training

23. Table 18.4

24. Types of Aerobic Endurance Training Programs Long, Slow Distance Training –Training is longer than race distance (or 30 minutes to 2 hours) at 70% of VO 2 max. –Intensity is lower than that of competition, which may be a disadvantage if too much LSD training is used..

26. Types of Aerobic Endurance Training Programs Pace/Tempo Training –Intensity at or slightly above competition intensity, corresponding to the lactate threshold Steady pace/tempo training: 20 to 30 minutes of continuous training at the lactate threshold Intermittent pace/tempo training: series of shorter intervals with brief recovery periods –Objectives Develop a sense of race pace and enhance the body’s ability to sustain exercise at that pace Improve running economy and increase lactate threshold

27. Sample Pace/Tempo Training Program for a 50 km Cyclist

28. Types of Aerobic Endurance Training Programs Interval Training –Exercise at an intensity close to VO 2 max for intervals of 3 to 5 minutes. Work:rest ratio should be 1:1. –This allows athletes to train at intensities close to VO 2 max for a greater amount of time. –It increases VO 2 max and enhances anaerobic metabolism. –Method should be used sparingly, and only when training athletes with a firm aerobic endurance training base....

34. Key Point The various types of training induce dif- ferent physiological responses. A sound program should incorporate all types of training into the athlete’s weekly, monthly, and yearly training schedule.

35. Section Outline Application of Program Design to Training Seasons –Off-Season (Base Training) –Preseason –In-Season (Competition) –Postseason (Active Rest)

36. Table 18.5

37. Application of Program Design to Training Seasons Off-Season (Base Training) –Begin with long duration and low intensity. Gradually increase intensity and, to a lesser extent, duration. Preseason –Focus on increasing intensity, maintaining or reducing duration, and incorporating all types of training. In-Season (Competition) –Program should be designed around competition, with low- intensity and short-duration training just before race days. Postseason (Active Rest) –Focus on recovering from the competitive season while maintaining sufficient fitness.

38. Key Point A sound year-round aerobic endurance training program should be divided into sport seasons with specific goals and objectives designed to improve perfor- mance gradually and progressively.

39. Section Outline Special Issues Related to Aerobic Endurance Training –Cross-Training –Detraining –Tapering –Resistance Training

40. Special Issues Related to Aerobic Endurance Training Cross-Training –Cross-training is a mode of training that can be used to maintain general conditioning in athletes during periods of reduced training due to injury or during recovery from a training cycle.

41. Special Issues Related to Aerobic Endurance Training Detraining –Detraining occurs when the athlete reduces the training duration or intensity or stops training altogether due to a break in the training program, injury, or illness. –In the absence of an appropriate training stimulus, the athlete experiences a loss of the physiological adaptations brought about by training.

42. Special Issues Related to Aerobic Endurance Training Tapering –Tapering is the systematic reduction of training duration and intensity combined with an increased emphasis on technique work and nutritional intervention. –The objective of tapering the training regimen is to attain peak performance at the time of competition.

43. Special Issues Related to Aerobic Endurance Training Resistance Training –Research is limited, but some data suggest that benefits can be derived from performing resistance training during aerobic endurance training. –Benefits may include Improvement in short-term exercise performance Faster recovery from injuries Prevention of overuse injuries and reduction of muscle imbalances –It can improve hill climbing, bridging gaps between competitors during breakaways, and the final sprint.
