Slowtwitch wrote an interesting article about leg shaving and its effect on aerodynamics. It turns out that the most aerodynamic setup is not fully shaved, but rather partially shaved in a certain manner. It’s odd looking, but an interesting study about turbulent flow boundaries. I’d suggest reading the whole article to understand all the details, but the short of it is that you should leave a stripe of hair down the front and chevrons across the backs of your calves for “significantly reduced drag.” Full article here.
A company called BSX athletics is trying to produce a product that you wear on your calf that would give you all the normal performance metrics (heart rate, cadence, pace, and calories burned), but it also claims to be able to measure your lactate threshold. Pretty cool bit of equipment if they can get it to work. It’s still in development and it’s on kickstarter. If you want to contribute, here’s the link for their Kickstarter page and the link to their page on the insight.
I started using heart rate variability (HRV) this year as a way to attempt to track my form so that I could have a slightly more scientific than “how I feel” method to know if I was overtraining throughout the year. I feel like I’ve now accumulated enough data to get a baseline for where I normally am and I’m starting to question myself a bit. I have a pretty good HRV (according to what the “experts” are saying) with an average of around 94. I suppose this means I’m relatively fit although I’m realistically just starting to train this year and I’m not really that fit yet.
I measure my HRV using the sweetbeats app shortly after I wake up. I try to do it every morning, but there’s typically a day or more per week that I miss. I only do the measurements prior to workouts so that I get my rested state each morning. I’ve now been doing base training for quite a while and I have yet Read the rest of this entry
