***In my previous post, I also referred an article by Kravitz where some

implications to training are inferred. Extracts provided:

" " What Are The Training Applications from this Acidosis Update?

Personal trainers and fitness professionals can utilize this contemporary

understanding of acidosis information for endurance and resistance exercise

design. For endurance training, a modern training method is “lactate threshold

training”, which is an aerobic training technique that helps to improve the

contribution of ATP from mitochondrial respiration, thus decreasing the reliance

on glycolysis. This type of training has been thoroughly reported in a past IDEA

Personal Trainer magazine article (Dalleck, L.C. & Kravitz, L. (2003).

Optimize Endurance Training, Volume 14 Number 1 pp 36-42). For optimizing

clients and students doing high-intensity resistance exercise, fitness

professionals are encouraged to also incorporate endurance exercise in the

training design. This important training addition will eventually lead to a

better proton buffering capacity for the exercisers, thus inhibiting a major

contributing factor to fatigue when they do their challenging resistance

exercise workouts. " "
