Anyone know...
 
Does anyone have proof that Anaerobic workouts are better than aerobic for endurance training? I read an article, and I'm trying to convince my coach to do more sprints than distance, and I think a scholarly article could help out quite a bit.

Although I know you should end up finding an article that proves what you are trying to get across to your coach, I searched around a little and found published article that Ano posted about long-distance running and the association of injuries, which I believe could help you with your persuasion:

Exercise, training and injuries.

Jones BH, Cowan DN, Knapik JJ.
Army Research Institute of Environmental Medicine, Natick, Massachusetts.

Although exercise results in a number of well documented physical fitness and health benefits, accruing such benefits entails a risk of exercise-related injuries.

Musculoskeletal injuries occur frequently among fitness programme participants, runners, athletes, military ******** and others who engage in routine vigorous exercise.

The same parameters of exercise (intensity, duration and frequency) that determine the positive fitness and health effects of physical training also appear to influence the risk of injuries.

Studies of runners and other physically active groups have consistently demonstrated that greater duration and frequency of exercise are associated with higher risks of injury.

However, the sports medicine literature shows little association between exercise intensity and injuries, a finding which may be misleading.

The strongest and most consistent association reported exists between greater total amounts of exercise and higher risks of injury.

This is not surprising, since the total amount of exercise is the product of the intensity, duration and frequency of exercise.

Recent military research confirms the finding that higher volumes of running are associated with higher rates of injury.

Furthermore, the study of army ******** suggests that greater amounts of exercise not only result in greater risks of injury, but in some instances may also impart no additional increase in fitness, a finding consistent with an earlier study of civilian runners.

Several military studies also demonstrate that those ******** who have been more physically active in the past are less likely to be injured during basic training.
T
hese military studies also document a number of other factors, such as older age, smoking, sedentary jobs and lifestyle, high or low flexibility and high arches of the feet, which may contribute to or modify the risks for exercise-related injuries.

In conclusion, the present review suggest that, for activities such as running, specific parameters of exercise may contribute to the overall risk of injuries in rough proportion to their contribution to the total amount of activity performed.

Also, better knowledge of the effects of the parameters of training and other factors on the risks of exercise-related injuries is necessary to make more judicious choices about how to best achieve the benefits of exercise and to prevent injuries.

Journal of Physiology, “Short term sprint interval versus traditional endurance training: Similar initial adaptations in human skeletal muscle and exercise performance.” Sept 2006, Vol 575 Issue 3.

Study specifics- comparison of 20 minutes of interval training (30 sec sprint/ 4 minute rest) with 90-120 minutes in the “heart rate zone.”

Results- same improvement in oxygen utilization. One hour per week vs. 4.5-hours per week.

Another study (from Clarence Bass's article) :

Izumi Tabata and his colleagues at the National Institute of Fitness and Sports in Tokyo, Japan, compared the effects of moderate-intensity endurance and high-intensity intermittent training on V02max and anaerobic capacity. (Medicine and Science in Sports and Exercise (1996) 28, 1327-1330).

http://www.ncbi.nlm.nih.gov/sites/en...ubmed_RVDocSum

Interestingly, the high-intensity protocol had been used by major members of the Japanese Speed Skating team for several years; it's a real-world training plan. As you will see, however, the protocol is unique among aerobic training programs for its intensity and brevity.

Many studies have been done on the effect of training on V02max, but little information has been available about the effect on anaerobic capacity. That's because until recently methods for measuring anaerobic capacity have been inadequate. This study used accumulated oxygen deficit to measure anaerobic energy release, and is one of the first to measure the effect of training on both aerobic and anaerobic capacity.

Notice that the duration of the moderate-intensity and the high-intensity protocols are drastically different: (excluding warm-ups) one hour compared to only about 4 minutes per training schedule.

Tabata's moderate-intensity protocol will sound familiar; it's the same steady-state aerobic training done by many (perhaps most) fitness enthusiasts.

Here are the details : In the moderate-intensity group, seven active young male physical education majors exercised on stationary bicycles 5 days per week for 6 weeks at 70% of V02max, 60 minutes each session. V02max was measured before and after the training and every week during the 6 week period. As each subject's V02max improved, exercise intensity was increased to keep them pedaling at 70% of their actual V02max. Maximal accumulated oxygen deficit was also measured, before, at 4 weeks and after the training.

A second group followed a high-intensity interval program. Seven students, also young and physically active, exercised five days per week using a training program similar to the Japanese speed skaters. After a 10-minute warm-up, the subjects did seven to eight sets of 20 seconds at 170% of V02max, with a 10 second rest between each bout. Pedaling speed was 90-rpm and sets were terminated when rpms dropped below 85. When subjects could complete more than 9 sets, exercise intensity was increased by 11 watts.

The training protocol was altered one day per week. On that day, the students exercised for 30 minutes at 70% of V02max before doing 4 sets of 20 second intervals at 170% of V02max. This latter session was not continued to exhaustion. Again, V02max and anaerobic capacity was determined before, during and after the training.

In some respects the results were no surprise, but in others they may be ground breaking. The moderate-intensity endurance training program produced a significant increase in V02max (about 10%), but had no effect on anaerobic capacity.

The high-intensity intermittent protocol improved V02max by about 14%; anaerobic capacity increased by a whopping 28%.

Dr. Tabata and his colleagues believe this is the first study to demonstrate an increase in both aerobic and anaerobic power. What's more, in an e-mail response to Dick Winett, Dr. Tabata said, "The fact is that the rate of increase in V02max [14% for the high-intensity protocol - in only 6 weeks] is one of the highest ever reported in exercise science." (Note, the students participating in this study were members of varsity table tennis, baseball, basketball, soccer and swimming teams and already had relatively high aerobic capacities.)

The results, of course, confirm the well-known fact that the results of training are specific. The intensity in the first protocol (70% of V02max) did not stress anaerobic components (lactate production and oxygen debt) and, therefore, it was predictable that anaerobic capacity would be unchanged.

On the other hand, the subjects in the high-intensity group exercised to exhaustion, and peak blood lactate levels indicated that anaerobic metabolism was being taxed to the max. So, it was probably also no big surprise that anaerobic capacity increased quite significantly.

What probably was a surprise, however, is that a 4 minute training program of very-hard 20 second repeats, in the words of the researchers, "may be optimal with respect to improving both the aerobic and the anaerobic energy release systems." That's something to write home about!

I'm Mr. Anaerobic, doing weights while skipping cardio so I'm all for anaerobic training over aerobic training, but I've never heard of anaerobic training being more beneficial for endurance. Where did you get this info? I'd like to see this article because I don't know of any world class sprinters outlasting marathon runners.

I think he meant for tennis endurance....

Back in my cross country days. We ran high distance over the summer to build our base. In season Sat was a long distance day, at least 10 miles. Sunday alternated between off and a 4 mile bridge run, basically interval training. During the week was usually a total of 6-8 miles.

Typical day was 2-4 mile warmup. then stretching. 2-3 mile interval training(could be quarters, sprints, fast 5k, whatever) 1-2 mile cool down, and stretching.

Main thing we never did the same thing twice in a row or even week to week. Our coach was always changing things up, so you never got bored.
