Muscle power is the ability of the muscle to do maximum
work within the shortest amount of time.

(Overload Principle)
Each individual's capabilities are determined by their
genetic makeup. Individuals with increased neuromuscular
efficiency incorporate greater numbers of muscle fibers
during contraction and therefore have the advantage in strength potentials. In general, men have more testosterone than women and therefore have a greater potential for accelerated growth.
Muscles have a tendency to adapt to repeated stimulus, thereby, requiring less energy and effort to execute the same task. This can inhibit muscle growth (hypertrophy) or fat loss that we are trying to achieve. There are
2 types of overload principles:
Increasing Weights - increases muscle size.
Increasing Repetitions - increases muscle strength
with less growth in size.
If you over-stimulate the muscle, growth in strength and size
will be inhibited. The levels of over-stimulation are
dependent on each individual. It would be unreasonable to double the amount of weights. Make sure that you can do at least 4 to 6 repetitions.
Specificity Principle
Muscle training for a specific task is called specificity. Although each person has individual variations in movement
for sports related activities, specific training essentially involves working the muscles in the same manner as it's expected use.
Muscle design evolves for a specific use. Care must be used when isolating specific muscles not to create an unbalanced condition. Unbalanced muscles may allow a particular muscle to work harder than the supporting and stabilizing muscles, thereby, increases the chances of injury.
Types of Specificity Principles:
Resistance - resistance is identical to or greater than
encountered during the activity or sport.
Movement - movement patterns mimic that
encountered during the activity or sport.
Muscle - specific muscles are exercised that will be
used during the sport or activity.
Speed - movement matches speed used during the
activity or sport.
