Competitive, elite athletes and sports trainers know that subtle changes in pH can have profound effects on the overall health, feeling of wellness, level of fatigue, pain, weight, ability to train and athletic performance. Muscles work best in a narrow range of Ph. At rest, muscle pH is about 6.9, while arterial blood is about 7.4. When we exercise, the increased use of muscle glycogen for energy produces lactic acid, pyruvic acid, and CO2, which decreases muscle pH. The harder you exercise the quicker your muscles become acidic which leads to fatigue. Accumulation of acid also limits the production of...
