I’ve reported in the past about studies suggesting running is good for your health and more is better. It’s not a certain thing, there is some evidence that it might not be, but what I’ve seen so far suggests that the data showing more is better or at the very least more isn’t worse is more reliable and convincing.
Maybe that’s hopeful thinking. If so, feel free to regard this as cherry picking. Two more studies suggesting that, at the very least, greater levels of exercise do not cause you health problems.
Some thoughts on why that new science backed supplement probably doesn’t work. Actually, this isn’t about science on a supplement. It’s about where studies fall short. More than anything, it’s a reminder that we need some critical thinking. Just because one study says something doesn’t mean much. It’s an indication that something might be true but look for multiple studies with very few contradicting ones before even thinking of saying they absolutely prove something.
Speaking of studies and supplements (even though we weren’t really): another study showing that vitamin D supplementation may not do much for you. This time in preventing bone fractures. This goes with studies suggesting that the supplements don’t help with various other health concerns. I suppose the lesson here is to be wary of supplements of any form. It’s almost certainly true that getting the nutrients from more natural sources is better and might be true that the supplement doesn’t really do anything for you.
Finally, who does drafting work for? Everyone! In fact, because we’re out there for more time, people running pretty much any pace benefit by about the same amount, from elites to 5 hour marathoners.
