I’ve been thinking about what constitutes “an excessive amount of of a superb factor” with endurance train for a while. I first mentioned it in my publish “How A lot Train Is Too A lot?” and gave an replace on it right here. I lately got here throughout an article within the peer-reviewed journal Vitamins that gave an fascinating perception into the connection between endurance train and eating regimen [1], particularly with regard to cardiovascular well being. They reviewed disturbing proof that those that do numerous endurance train could also be at elevated danger for coronary artery illness, and commented “surprisingly, endurance athletes could have extra superior atherosclerosis and extra myocardial harm, in contrast with sedentary people, significantly as they age”.
The authors then identified that endurance athletes are likely to eat greater than their sedentary counterparts, to gasoline their exercise. However this additional gasoline isn’t essentially wholesome, particularly if they’re consuming a typical fashionable eating regimen just like the Commonplace American Food regimen. Since many specialists consider such a eating regimen accommodates extreme quantities of animal protein and saturated fats, consuming greater quantities of it might make issues worse. They then go on to argue that these exercisers can be higher off consuming a wholesome plant-based eating regimen which might reduce the load of animal meals that will contribute to arterial plaque formation. It might additionally scale back one other contributor to coronary artery illness, irritation.
I found this text in a video on Dr. Michael Greger’s web site entitled “Why All Athletes Ought to Eat Plant-based Diets“. He reviewed the proof that has been beforehand offered on the advantages of plant-based diets for athletes, most famously within the documentary “The Gamechangers“. However he additionally emphasised the brand new perception offered in ref [1].
Whether or not a plant-based eating regimen is critical to scale back the danger of coronary artery illness amongst ageing athletes could also be controversial. First, I at all times wince once I see “plant-based” as an alternative of “whole-food plant-based”. I understand the latter is awkwardly lengthy and it might be tempting to simply say “plant-based” as an alternate, however this can be a slippery slope. There are a lot of unhealthy overprocessed meals which can be nonetheless plant-based, resembling sweet and potato chips. Second, extra animal protein and saturated fats are usually not the one issues unsuitable with typical fashionable diets, in addition they comprise extreme quantities of sugar and different “dangerous carbs”. However I feel it’s clear that ageing athletes ought to keep away from the temptation of considering they’ll eat no matter they need and they’re protected by their train. Even for individuals who are usually not satisfied it’s essential to comply with a whole-foods plant-based eating regimen, it might nonetheless be a good suggestion to comply with wholesome consuming suggestions, resembling Harvard’s Wholesome Consuming Plate.
Within the well-known novel As soon as A Runner, the lead character, a aggressive collegiate runner, describes his consuming by saying “if the furnace is sizzling sufficient it doesn’t matter what you set in it”. I feel many athletes have this angle, I actually leaned in that route once I was youthful. I used to be pleased I may get away with consuming just about no matter I needed so long as I exercised sufficient. However I consider this turns into extra harmful as we age.
