Immediate Effects Of Exercise On The Muscular System
- Exercise increases the body's demand for oxygen
and glycogen as the muscles need more fuel to
function because they are contracting and
lengthening at an increased rate
- Extra waste products are created when muscles work
harder than normal, and extra blood needs to be pumper
around the body to take these waste products away
- Extra waste products are created when muscles work
harder than normal, and extra blood needs to be pumper
around the body to take these waste products away
- When the demand for oxygen is so high that
not enough can be provided to the muscles,
lactic acid begins to build up until eventually it
is not possible to continue
- Isotonic Contractions
- One works while the
other relaxes
- Occurs when a muscle contracts and
works over a range of movement
- EG. Walking and running
- Most weight training and circuit training
exercises use isotonic contractions
- One works while the
other relaxes
- Isometric Contractions
- Occurs when the muscle contracts but
stays in a fixed position
- EG. Plant position
- Not used during sport as much as
isotonic contractions
- Occurs when the muscle contracts but
stays in a fixed position
