Despite outstanding new scientific research, that is telling us that many modes of training, which has been popular the last 20 years are now a long way out of date, but so many triathletes continue to follow the “Lydiard system” of endurance running training, Jack Daniels, periodized blocks of training for endurance athletes, and place heavy emphasis onVO2 max development and high mileage, and Anaerobic training.
Even lactate testing to establish lactate threshold philosophy ie speed above, which lactate begins to accumulate ,by measuring blood lactate levels at various training to established lactate threshold velocity by which it was believed once the velocity had been identified you could carry out heavy quantities of training at this level.
Science now tells us that training at threshold is just a moderate stimulus for threshold improvement, to truly max out, the threshold, you need to expose your muscles to large amounts of lactate . So, the muscles can get really good at picking up lactate from the blood and tissue spaces and using it for energy, by definition, working at threshold produces little lactate and so muscles can’t learn how to make lactate disappear very well.
To boost lactate threshold to the greatest extent. You need to work above the threshold, and that couldn’t be easier to endurance athletes. As long as you train at intensities, which could not be sustained continuously and more than 20 minutes or so during training. You are, above LT, and you are teaching your muscles to utilize lactate for energy more efficiently.
I am a great believer in functioning strength training,form, and all the micro movements that go with a particular skill I E swim, bike, run as in the case of the triathlon.
Slogging out endless kilometres, with no form is a waste of time and may be fooling yourself and getting bragging rights about the amount of work you have done. Not to mention the damage and injury risk you are putting yourself through.
Circuit training, improves strengthwhich lowers the risk of injury, helps to improve efficiency of movement and can be the prelude to considerably more powerful running, cycling or swimming.
In addition, circuit work can heighten Vo2 Max with intense effort. So the training can also heighten lactate threshold, the best predictor of endurance performance as key research has shown. by circuit training. You can improve all five key variables, which are important for endurance success, which is strength, power, economy, VO2max ,and lactate threshold.

I am very excited know this form of training. It lowers the risk of injury and improves efficiency of movements, which is great. Thanks for your informative article.
