What are the long term positives of exercise on the Musc. System

Increased thickness of muscle fibres
Increased strength of contraction and potential neuron size

increased glycogen stores

increase in myglobin

more capillaries

increased tendon strength

What ar the long term negatives of exercise on the Musc. System

Repeated bouts without rest can cause over use injuries
Possible injuries can occur, commonly in the tibialis anterior

tendonitis

What are the short term positives of exercise on the M. system

Increased blood flow
Muscles heat up, allowing more flexibility and can apply more force over a long joint range

Short term negatives of exercise

increased chance of muscle soreness
depleted myoglobin levels and energy stores

lactic acid build up

effects of a warm up on the muscle systems

increased blood flow/O2
increased muscle temperature

increased speed and force of contraction

effects a cooldown on the muscle systems

remove lactic acid
prevents blood pooling

restores O2 levels stored in myoglobin
