Acidic and alkaline water, pH all water and all aqueous solutions contain both H+ and OHâ ions. If the quantity of H+ exceeds that of the OH-, the water is said to be acidic. If there are more OH-ions than H+, the water is alkaline. Pure water, which contains equal numbers of both ions, is said to be neutral. Chemists express the degree of acidity or alkalinity on the pH scale which runs from about 0 to 14. Acidic solutions have pH values of less than 7, alkaline solutions more than 7.
Examples of anaerobic exercise include weight lifting, sprinting, and jumping; any exercise that consists of short exertion, high-intensity movement, is an anaerobic exercise.
Biking sprints, swimming sprints and running sprints are examples of anaerobic activities. During sprinting, the muscles rapidly deplete energy reserves before heavy breathing begins.Sprinting demonstrates the requirement of a significant amount of oxygen needed by muscles to perform the activity.ince muscles require oxygen to maintain prolonged exertion, anaerobic exercises can only continue for short periods of time. Examples of anaerobic activity include sprinting, high-intensity interval training, powerlifting and most athletic sports.
