Triathlon Swim
Swim slower for faster triathlon times
In the study
nine highly trained male triathletes completed five separate sessions in the laboratory
including a graded exercise test
a swim time trial and three sprint distance triathlons.
The swimming velocities of the three triathlons were 80-85% (S80)
90-95% (S90) and 98-102% (S100) of the time trial velocity
while subsequent cycling (on a cycle ergometer) and running
(on a 250m grass track) were performed at a perceived maximal intensity.
The two most important findings were as follows:
• The S80 and S90 cycle times were faster than the S100 time;
• The overall triathlon time of S80 was faster than that of S100.
The overall mean time improvement of about 1 minute 45 seconds between S100 and S80
is clearly of huge significance to elite athletes
when the difference between first and second place can be as little as one second.
‘The findings of this study suggest that swimming intensity had a significant influence
on subsequent cycling and overall triathlon performance during a simulated sprint distance triathlon,’ conclude the researchers.
However, rather than recommending elite triathletes to swim slower
the researchers advise them to elevate their swim training to the same level as cycling and running.
This should equip them to ‘swim the initial discipline of an event at an intensity below maximum
without losing touch with the first pack of swimmers.
