Coach's Column with Namrita O'Dea: Sports Supplements Are They Good or Bad for Me
are your thoughts on taking sports supplements and are they helpful or
potentially detrimental to one's health?"
easy answer is a supplement, regardless of the scientific evidence behind it,
should only be used as just that...a supplement.
Depending on the supplement, that means it should be taken only at certain
times of a training phase, for a specific purpose before/during/or after a
workout, and not in excess (i.e. more is not better). Further, the main focus
for any athlete serious about performance gains should be a diet from varied
natural food sources and adequate sleep and recovery.
That being said, there are
certain ergogenic aids that have fairly strong scientific evidence to support
their use. For example, a dose of 3-6 mg/kg caffeine can help boost endurance
performance and mental function. Contrary to previous beliefs, caffeine taken
in these moderate doses is not dehydrating. You have also probably heard all
the recent buzz over beets. The nitrate content in beetroot juice supplements
decreases the oxygen cost of moderate intensity exercise and also appears to
increase exercise capacity (time to exhaustion) and endurance exercise
performance. The optimal dose seems to be around 500 mL of regular beetroot
juice or the equivalent in a beetroot juice supplement (like the BeetElite
Neoshot, Pure Clean Powder, or Beet It sport shot).
What about antioxidants?
Vitamins A, C, and E may be beneficial in small doses or for very short periods
of time. However, when taken in large doses of supplements or for extended
periods of time, these antioxidants may interfere with training adaptations at
the cellular level; but, whether these effects translate to actual performance
changes is still unclear. Your safest bet is to include a few different
"superfood" smoothie recipes in your diet that can be used as pre-
and post-workout real food supplements. A Vitamix is a great investment and
allows you to quickly blend up superfoods like carrots, ginger, greens,
spinach, beets, and frozen berries.
Finally, all athletes should
take responsibility for what they put in their body. No supplement can be
certain to be free of banned substances and the ingredients label should not be
relied upon to verify that a supplement is clean.
