Do away with no-pain-no-gain in Interval training

We are all likely familiar with the 80:20 rule of life (Pareto principle); 80% of the effects come from 20% of the causes. How does this apply to athletic training?
80:20 rule of Interval Training
Studies have also shown that for middle distance athletes working in high intensity intervals the best results are found when these intervals comprise no more than 20% of the training time with low intensity aerobic work making up the other 80%. Further, findings show that the most common mistake of the non-elite athlete was to fade both ends to the middle. In other words their high intensity was not high enough and the low intensity not low enough.
In an hour training session this means that fully 48 minutes should be in your aerobic zone while 12 minutes should be hard core above anaerobic threshold. For this anaerobic work, I recommend work that supports the timeframe of your race duration. For dragon boat racing the 500m is the most common distance. Interval training that supports lactate movement and middle distance endurance is best. This means working from 30-90 second sprints up to 5 minute high intensity runs. Make sure your recovery times average 2x the intense timeframes, and move straight into low intensity work to get the toxins, created by your anaerobic work, out of your system.
In a one hour training session the warm up and cool down (all aerobic work) should account for about 50% of your training time which leaves 18 minutes aerobic/rest with 12 minutes of high intensity work interspersed. Rest periods can be either full rest, or active rest at 50% effort, depending on the duration and intensity of the interval.
I use a 50% intensity level for our rest periods between our 100% intensity intervals. Make sure these intensity levels are appropriate to the duration, with 100% for 30 seconds being higher intensity than 100% for 5 minutes.
Maintaining this ratio consistently and making sure the appropriate intensity levels are maintained will produce the best results, and again reduce the chance for injury. Make sure to keep your paddlers on track by emphasizing the low intensity sets remain low (i.e. 50-60%) and this high intensity sets remain high! This will maintain the optimum body activity while giving the strength and speed work needed for middle distance athletes.
Using this along with High Intensity Training as tools to help you bypass the no-pain-no-gain mentality will produce long term, heathy, injury free athletes who turn around and maintain great results.
A pretty good 80:20 rule to train by.
