This list of 10-healthy running commandments is way better than most. How can you fail to appreciate “Running is bad dance practice,” so work on side-to-side movements? Or, “Thou shalt not start a run with cold feet.” That’s a novel notion. I also support any article that points out the overuse of NSAID painkillers and the benefits of elevating the legs for 5 minutes every evening. Ahhh, feels so good.

That research supports a several-week, disciplined step-down approach. Now, a big-data analysis of 158,000 recreational marathoners has concluded much the same. Rec runners who followed a minimal taper ran about 5:30 slower than similar runners who used a strict 3-week taper. Women received a bigger boost than men from a proper taper.

My friends running Boston are already checking the weather outlook. It’s good, but you know what they say about the weather in New England … and nearly everywhere else. Wait 15 minutes. An October Boston could be a little warmer than April, but might also provide some tree shade in places. These things are important to prevent heatstroke. A new paper from Boston’s crack medical team reports that heatstroke cases have developed mainly at temperatures in the mid-60s and above, and mostly among younger, faster runners. That’s because your pace is the biggest trigger to rising body temperature.

This was first shown more than a decade ago, though recent reports have been less conclusive. Now a new meta-analysis has confirmed this effect. It suggests taking acetaminophen 45-60 minutes before a big effort.

Sure, you know that good, consistent sleep is important for your training and racing. But did you ever think about springtime marathons run the day after the beginning of Daylight Savings Time (and one-hour loss of sleep) vs. the opposite time in fall? That’s what this report investigates. And the result: Fall “wins” by a whopping 11 minutes. Even a new pair of super shoes would be hard-pressed to match that.

In fact, nothing has changed in terms of your calorie burn per mile of running. It’s still roughly 100 calories per mile (or .75 x your body weight in pounds, if you want a more precise estimate). After you run those miles, however, your body dials down your calorie burn. You either move less or conserve energy through little-understood biological mechanisms.

Maybe a little Since the above paper just robbed you of some weight-loss calories, here’s a surprisingly good story about boosting your metabolism. Stories like this typically provoke howls of protest from physiologists and nutritionists who say, “Nope. Can’t be done.” They're talking mainly about basal metabolism, admittedly hard to change. But a few little tricks throughout the day can give you a short boost, which could prove helpful. That’s what this article provides.

To find out, they recruited 18 competitive middle-distance runners to run hard on a treadmill for 3 minutes. At the end of that time, the runners’ plantar flexor muscles were contributing less, which forced the knees to work harder. Conclusion: “Improving the fatigue resistance of the plantar flexors might be beneficial for middle-distance running performance.” You can find many [internet articles](113/cy08X04/VWsS7l2zyfZmW6sCmR99b-3_2W6hm-BV4y4QJxN6WXHYt5nCTJV3Zsc37CgLWzW4hymFy9cv0bWVCnFKR2Z8GfBW8RWQL28GP6ldW8LMtYD67Y-LpW8z75fK8vF7kKW91tRRz7_tTdBW3-ydr76nhlrkW6Mcznn9bKYqMW17TMxC4ny751W8z-40q5Vd7L6W42bWXY1XFhnmW2kdsDs1lVhpzW8W9zGG5NCks8W6JN_1F1S_pP7W4RlCMs1F8dlHW9kznFn876n-RW1wwKwR9bDGYXN2nd47m_r48hW2gKWFD4F25gXN32R8MFy8sfhW77t95g3phTmpW6RZCbg4PBPLhW1bsTHn7RCnr9W8WkXPk7st67RW5tV5vt6R4csMW6f1BjK26KDNyW4gG92f9hTY_BW2lCW1f1-jQK1W969LGP81vW7DN8PydTr9_pfYW9lKd6m7_KMN3VgGtTD3j10Rz3mgp1) and videos on plantar flexion exercises.

Wrong again. At least there’s no evidence so far. In this new study of first-time marathon runners, the directional arrows actually point the other way. “Running 500 miles over 4 months plus a marathon for the first time had no adverse effects on the lumbar spine.” And: “Additionally, there was evidence of regression of sacroiliac joint abnormalities.” Listen to your body, but don’t be afraid.
