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.
Aerobics is the term coined by Dr. Kenneth Cooper in 1968 to describe sustained low to moderate cardiovascular exercise. Aerobic activities include jogging, cycling, rowing, swimming and group exercise classes such as step. Aerobic exercise offers a wide variety of benefits to your heart, lungs and muscles. Aerobic exercise affects your muscles in the long term as a result of your workouts and also in the short term while you exercise.
