Protocol for Round vs Oval Chainrings. This is now starting on January 2014 and will have an 2 participants.
Hypothesis: Ovalised Chainring will increase power that is
produced while cycling.
Null Hypothesis: Ovalised Chainrings will have no effect on
power that is produced while cycling.
Over a 4 month period of training every month the chain ring
will alternate between round and Oval chainrings
Starting January 2014
1st Month Round
2nd Month Oval
3rd Month Round
4th Month Oval.
The expected results for the null hypothesis is that there
will be a linear increase in power over the 4 months of base training.
The expected results for the positive effect for the
ovalised chainrings will be a rise in power will the Ovalised chainrings and
then a slight fall or levelling off of power when returning to the round chain rings.
All training interventions will be recorded so that any
increase or decrease of power can be seen if effect from training or use of
chain rings.
Testing:
As I will also be losing weight, this will be recorded as
well.
Base ramp test will be performed
Every 2 weeks will perform a ramp test = middle of month and
end of month before change of chain rings.
Over the 4 months Power and heart rate data will be recorded
for each training ride. 20 min and 60 min average power will be recorded for
each ride. Any other non cycling training (running, strength and skiing) will
be record.
Same test will be performed at the end of period and 2 weeks
after test is complete.
