» Gettin' old, no worries
It's been quite a year (2008) for older athletes! Dara Torres
was back in the pool to add a few more Olympic medals to her collection
at age 41; Constantina Tomescu-Dita wins the Women's Olympic Marathon
decisively at the ripe old age of 38; And Lance Armstrong gets dropped
by 44-year old Dave Weins who wins the Leadville 100 mountain bike
epic for a 6th time! So is 40 the new 30 for endurance athletes?
By my reckoning (and my own experience) one's ability to perform
at the max levels of 20s and early 30s begins to slip during the
late 30s. Most elite level endurance athletes are done by this point.
Yet some keep going for a few more years with no apparent loss of
top end performance.
Having been an endurance athlete for 35 years, I can say experience
counts for a lot. Knowing when to back-off before getting injured
or burning-out; knowing what works for peak fitness and what doesn't,
and knowing how to tune the confidence factor so race day is your
best day all improves with age.
It's a fact that very real physiological changes happen with age
that slow us down. The head may still be as ready as ever to go,
but the body needs more TLC than it once did. I can't describe all
the exact subtle changes, but the first obvious difference you may
notice is a drop of max heart rate. Resting HR should not change.
Top end speed during anaerobic efforts is diminished, while endurance
holds pretty well, and economy even may improve. As we get older
recovery takes longer so we can't accomplish the same bulk of training
over a set period of time. Healing takes longer; at 50 that calf
strain will take twice as long to heal as it did at 30.
So it's a good thing there's age group racing! Though times will
suffer—speaking from the wisdom of my 5th decade—I can
say that the sensation and satisfaction of a good workout or
race doesn't diminish with age.
The consensus is that the run 'goes' first. Or perhaps that's just
the discipline we measure and analyze most closely. The run is also
the discipline that requires significantly more conservative training
as injuries can set you back in a way they didn't when you were
younger. The limiter is recovery and healing time which doubles
by age 50.
The good news is that swimming and cycling don't take quite as much
of a hit with age. Without the impact stress of running, recovery
is not as much as an issue in the water and on the road (or trainer).
So how much speed will one lose over time? One source says to expect
1% of top end (max VO2) speed loss for each year over 30. This seems
high. For me it was more like .75% starting during late 30s, or
maybe 1% starting at 40, either way you will get slower.
Good news for endurance athletes who begin at 40 is that there are
several years when performance keeps improving relative to where
you started. If you were not training well during your 20s and early
30s the contrast between then and now (40+) is not there!
