Cardio Produces Acidic pH
The other potentially harmful substance generated during aerobic exercise is lactic acid. Again, this substance is produced during exercise based on intensity and duration, and is an important consideration as an exercise stressor because it lowers pH. Simply running for a few minutes, drops our normal pH of 7.4 to 7.0. Continuing or repeating the same activity can lower it to 6.8, which is considered the lowest tolerable survival pH. As we discussed earlier, many mistakenly think that cancer can only grow in an acidic environment and attempt to blame food for that, yet conveniently forget that their 2hr run that same morning puts them in a more harmful state of acidosis (low pH). The buffering systems (to bring pH up) we have built-in to handle an acidic-food are not as effective during exercise. For instance, the kidneys regulate pH after an acidic meal by excreting more or less bicarbonate. This is unfortunately an ineffective regulator for dealing with the pH stress from exercise, as it can take several hours to react. Additionally, research that supports correlations between cancer and pH focus on increased acidity (low pH) in blood and other fluids. Our diet cannot alter the pH in blood, whereas our exercise habits can.
Large amounts of lactic acid are produced during exercise that’s beyond a certain intensity or duration that increases oxygen and acidity (lowers pH) inside and outside muscle cells. Accumulation of lactate depends on a balance between production by the working muscles and removal by the liver and other tissues. If exercise is continuous, lactate production persists while removal declines. This lactate build-up not only adds to the stress put on our cells, but arterial pH disturbance alone has been associated with life-threatening rhythmic disturbances of the heart.
One of the reasons endurance exercise is more damaging than other forms of exercise, such as weight training, is because intense oxidation and acidity occurs in all ‘active’ muscles. For instance, diaphragm muscle is continuously stressed throughout an endurance bout, meaning that free radical and lactate accumulation is consistently produced for the entire 45, 90, or 120min bout. With cardio, the same muscles are experiencing the same high stress and low pH during the entire duration, with no time to recover until the activity is over. This concentrated overload is what causes damage, as opposed to a properly designed weight training program that stresses a single muscle or group of muscles for a short period of time followed by ample recovery. Furthermore, most involved in weight training allow ample recovery (72hrs) between muscle groups, as opposed to cardio where it’s very common to returns to the pavement, bike, or pool the very next day!
Cardio Decreases Immunity & Reproductive Health
Inflammation and oxidation are 2 of the biggest factors in determining whether or not you develop a life threatening disease. Both are necessary in acute and infrequent doses for survival, but when experienced chronically, the biological clock starts ticking. Endurance training promotes cortisol secretion and discourages anabolic hormones. This creates inflammation in the brain, reproductive system, intestinal tract, and heart. The other factors supporting inflammation are oxidative stress and chronically elevated insulin, which are both characteristic of the long distance runner, cycler, or swimmer. This is likely why:
T he elevated inflammatory markers experienced after aerobic exercise are much higher than those tested after alternative forms of exercise.
This inflammation and oxidative stress from extended duration aerobic training facilitates immune suppression and a decrease in reproductive function. Specifically, endurance athletes are at a higher risk of upper respiratory tract infection (URTI) and face reductions in overall immune function. This is very similar to
