I've written previously about the race of SCA at long-distance running events. We learned from a careful study (of nearly 11 million runners) reported earlier this year that the rate of SCA is approximately 1 per 100,000 marathon participants and approximately 1 per 300,000 half marathon participants. The mean age of victims was 42 years and 86 % were men. Form the non-surviving victims in whom autopsy information was available, the vast majority had an underlying heart condition such as hypertrophic cardiomyopathy (HCM), other abnormal hypertrophy, heart valve disease, or coronary artery disease.
SCAはSudden Cardiac arrestのことで、突然の心停止
Interestingly, the occurrences of SCA were not distributed uniformly along the length of the race. In marathons, the SCA events were much more common in the 20 mile-to-finish segment. Similarly, in half marathons, the SCA events were much more common in the 1- mile-to-finish segment. One reasonable hypothesis is that the SCA events in the final miles of the races may be linked to an increase in adrenaline levels as runners lift the pace or surge toward the finish line.
マラソンのレース中にお亡くなりになるランナーの平均年齢は42歳、86％が男性、死後剖検された症例の大半は心臓に基礎疾患を有していた。SCAが起こるのは、レースの後半に多く、フルであれば32km以降、ハーフであれば16km以降に多い。
どうやら、先週末のトライアスロンで2名の参加者がお亡くなりになったようで、これを見て急遽、アスリートの人たちへ提言を掲載されたようです。
出典はInternational Marathon Medical Director's Associationが2010年にまとめた提言のようで、これから抜粋されています。

1. Participants should be well-trained and have a race plan that matches their level of training and fitness.
2. Have a yearly physical examination being sure to discuss your exercise plans, goals, and intensity at that visit.
3. Consume a baby aspirin (81 mg) on the morning of the race if there is no contraindication to do so. I'd recommend discussing this with your doctor beforehand.
4. Consume less than 200 mg of caffeine before/during a 10K or longer race.
5. Only drink sports drink (or equivalent) in races of 10K+.
6. Drink for thirst.
7. Do not consume NSAIDS (eg, Motrin, ibuprofen) during a race of 10K+.
8. Consume salt (if no medical contraindication) during a 10K+ race.
9. During the last mile, maintain your pace or slow down; do not sprint the last part of the race unless you have practices this in your training.
しっかりとレースに向けて自分の身の丈に合ったトレーニングを重ねること
毎年の健診を怠らないこと。
支障がなければ医師と相談の上アスピリンを服用すること
10km以上のレースで服用するカフェインは一定量（200mg）以下に留めること
水ではなくスポーツドリンクを選択すること
口渇には水分を摂取すること
ロキソニンなどNSAIDSはレースではダメ
塩分を補給すること。
最後の1マイルだからといって頑張らないこと
