work is
equivalent to an amount of energy in mechanical form
power is
the rate of which work is done
power is measured in
watts
Maximum power output during a single contraction
is increased by muscle temperature.
The velocity with which a myocyte shortens is proportional to
the rate of cross bridge cycling
Temperature influences maximum muscle power output via its effect on the
maximum rate of cross-bridge cycling
Compared with slow twitch myocytes, fast twitch myoctes contract rapidly but relax
quickly because they provide energy for relaxation at a greater rate
One way in which several weeks of training can increase muscle power is by
reducing the time it takes to maximise the recruitment of motor units during a contraction
Generally long fusiform muscles shorten more quickly than highly pennated muscles because
because they tend to be longer and relative to their length have more sarcomeres arranged in series
Warming up your muscles before a maximum isometric contraction will
have no effect on maximum force during contraction
