Exercise prescription dosages
1 repetition maximum testing
"the highest amount of load lifted for a specified number of repetitions" (Bird & Marino, 2005)

The ability of a muscle to generate force to withstand stress and is usually calculated based on the 1 repetition maximum. Strength is a fundamental factor of all functional activities and the foundation to all rehabilitation programs (Lorenz & Morrison, 2015) and is attributed to by both neural and muscular mechanisms (Bird, Tarpenning & Marino, 2005). It is directly related to muscle hypertrophy and is a component of both power and endurance (Anemaet & Hammerich, 2014)
The ability of a muscle to repeatedly contract with low load – OR to maintain a contraction for an extended period (Brody, 2012)
An exercise induced increase in the size of existing myofibrils leading to an increase in muscle mass. There is not an increase in the number of muscle fibres (Bird, Tarpenning & Marino, 2005).
The ability of an individual to use the available strength quickly (power = work/time or power = force x velocity) (Anemaet & Hammerich, 2014). Power is not only the ability to move external loads quickly – it can be seen in ADLs such as climbing stairs, opening doors, or performing a sit to stand movement and is important in falls reduction in the elderly (Granacher, Zahner & Gollhofer, 2008).
