During high intensity exercises your cells become unable to perform aerobic respiration causing them to perform anaerobic respiration. This causes a build up of lactic acid in the muscles.
An example of a physiological physical stressor is intense exercise, which can challenge the body's homeostasis by increasing heart rate, blood pressure, and temperature, as well as causing muscle fatigue and dehydration.
The phosphagen system, specifically involving creatine phosphate, is primarily used at the beginning of exercise and during high-intensity short-duration exercise. This system provides quick energy through the breakdown of creatine phosphate to regenerate ATP, which fuels muscle contractions during these intense activities.
During rest and low-intensity exercise, muscles rely on stored glycogen as a source of energy. Glycogen is broken down into glucose, which is used for fuel by the muscles. If glycogen stores are depleted, the body may turn to other sources of energy, such as fat.
One easy way to measure endurance exercise intensity is to use the Rate of Perceived Exertion (RPE) scale, where you rate your effort on a scale of 1-10. Another method is to monitor your heart rate using a heart rate monitor and aim for a specific percentage of your maximum heart rate based on your fitness level. A third option is to use a fitness tracker or GPS watch that calculates metrics such as pace, speed, or power output to gauge intensity.
Adults should aim for at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity exercise per week, along with muscle-strengthening activities on 2 or more days a week. It's also important to incorporate stretching exercises to improve flexibility. The specific amount of exercise needed can vary depending on individual health goals and needs.
