Mass gainers are the next step up from standard protein powders for those who wish to make greater gains in size and strength. Mass gainers are essentially a protein shake that has had the calories increased with the addition of carbohydrates. As building muscle is a calorie intensive process, more calories than the body requires to maintain weight are needed to fuel the process of hypertrophy and as carbohydrates, or more precisely, the muscle glycogen they turn into when ingested, are the body’s primary energy source, an abundance in the diet provides the foundation required for growth.

The efficiency of human muscle has been measured (in the context of rowing and cycling ) at 18% to 26%. The efficiency is defined as the ratio of mechanical work output to the total metabolic cost, as can be calculated from oxygen consumption. This low efficiency is the result of about 40% efficiency of generating ATP from food energy , losses in converting energy from ATP into mechanical work inside the muscle, and mechanical losses inside the body. The latter two losses are dependent on the type of exercise and the type of muscle fibers being used (fast-twitch or slow-twitch). For an overall efficiency of 20 percent, one watt of mechanical power is equivalent to kcal per hour. For example, one manufacturer of rowing equipment calibrates its rowing ergometer to count burned calories as equal to four times the actual mechanical work, plus 300 kcal per hour, [16] this amounts to about 20 percent efficiency at 250 watts of mechanical output. The mechanical energy output of a cyclic contraction can depend upon many factors, including activation timing, muscle strain trajectory, and rates of force rise & decay. These can be synthesized experimentally using work loop analysis .
