 4 training essentials you can’t afford to screw up

If you look at any analysis of training plans and coaching methods, you mostly see just one thing: workouts. Do your long runs this way, and your tempo runs this way, and your intervals this way, and don’t forget hill repeats and the occasional post-run strides.


Do each of these X times per week at Y pace for Z distance. There you have it. A complete training plan. 


Except. Maybe not. According to a new report, the first to ask coaches what they consider the essentials of a training program, workouts fell to the bottom of the list. The report’s conclusions found that “notably and perhaps surprisingly less than a third [of coaches] explicitly rated physical training as the most important factor in determining sports performance.”


These results came from a survey of 106 coaches with an average of 15+ years of coaching mostly individual sports.


What did the coaches rate as more important than key workouts? Here’s the list of 4 big factors: the coach-athlete relationship (56%), life stress (41%), athletes’ “belief in the plan” (37%), and psychological and emotional stress (35%).


The authors’ main point: If physical training is less important than other factors, why does so much exercise science try to derive physical measures like vo2 max, lactate threshold, and muscle fiber percentages? Training science begins with the pervasive presumption “that the mechanisms underpinning physical training adaptation are sufficiently well understood to facilitate accurate training prescription.” 


However, the new coach-centered survey produced a different viewpoint. “Currently, the science seems mired in a strict biomedical conceptualisation of training theory. Many coaches, in contrast, believe non-physical influences affect training adaptations.”


As a result, there seems to be a mismatch between much scientific research and the actual application of key training principles. Future research should aim to turn things inside-out a bit more, and produce plans more attuned to the athletes' full-life. 


And when it comes to individual athletes themselves? It seems clear that they should spend less time looking for magical workouts, and more time on big-picture items like an honest discussion and appraisal of their current training, along with greater emphasis on life stresses.

6 ways to keep improving in the marathon (year after year)

Here’s a great article, written in two voices (coach and athlete), about one individual’s 8-year path to improving the marathon segment of his Ironman Triathlon races. During this time, Jan van Berkel lowered his Ironman marathon time from about 3:20 to 2:37, guided by coach Dan Plews. 


The piece is instructive in part because several of the approaches they followed were atypical. They would not have been advised by a council of coaches, but they worked for this particular coach-athlete partnership. Here are a few that caught my attention.


Van Berkel disregarded practices like massage, physical therapy, and stretching, all of which “did bring some skepticism from those around me.” Instead, he emphasized sleep and good nutrition, as well as “running in barefoot shoes or on grass periodically.”


He also did a lot of hill running, which he believes is “significantly underrated” by others. “Strength eventually translates into speed,” he says. “I sought out routes that completely challenged my legs.” He did many of these runs after a long bike ride.


While Van Berkel consumed ample carbohydrates during his Ironman races, he often trained in a low-carb state, and even ate fewer carbs than most in his normal day-to-day meals. Plews explains: “His diet also featured a periodized distribution of carbohydrates centered around training, but also generally lower in carbohydrates habitually.” 


Lastly, Van Berkel mostly trained at a low intensity, with occasional tempo runs and strides at the end of easy runs. This changed dramatically in the final buildup to his biggest races when he began running repeat 800s or 1000s at close to his vo2 max pace. Plews: “By saving these sessions for the final build-up, we not only mitigated injury risks but also ensured a last-minute boost to his running performance just before race day.”


This article emphasizes how a close coach-athlete relationship, and a belief in the plan, can produce strong results even when the plan is a bit unusual. That’s a good message overall. Do what you enjoy and what works for you. More at EndureIQ.


Don’t buy your next pair of running shoes without reading this first

Here’s an article written by someone who worked 2 years in a top running shoe retail outlet, and an additional 7 years with a shoe company. He says: “In that time, I learned there’s a sizable knowledge gulf between folks in the industry and most consumers.”


This happens because brands produce so many similar shoes, or SKUs (Stock Keeping Units). They don’t do this to confuse consumers, but to offer a wide selection that allows everyone to find a shoe that should be the best for them. Of course, since you don’t get to run 100 miles in each pair, this does ultimately become confusing.


So what can a typical mystified shoe buyer do? The article offers 9 things you ought to know before handing over your credit card. Among them, three seem really important to me.


1--The most comfortable shoe is probably the one you should buy. Not the most expensive, or the one with the most heavily advertised features. Comfort is rule one in shoe buying.


2--Running shoes don’t cause injuries. Don’t look down at your feet if you’re troubled by frequent injuries. Look at yourself in the mirror, and admit that you probably made several training mistakes that led to your injuries. Start over again. Train smarter this time.


3--Don’t worry about “support.” No one really knows what support is or means in a running shoe. Or perhaps it means something different to each user. Revert back to rule 1--the comfort rule. That’s where you should focus your attention. More at Outside Online. 


8 steps to improve your mental game

Running presents so many fascinating contrasts, or paradoxes. For example, running is easy, right? You learned as a child, and didn’t need parents with a PhD in biomechanics to instruct you.


On the other hand, running is hard work. While slow walking constitutes a low-intensity exercise, everything changes as soon as you break into a jog. Now you’re in the moderate-to-vigorous zone. You breathe harder, you start sweating more, you burn twice as many calories per minute.


Yes, running is hard work. That explains why all the neighborhood walkers never enter a local 5K, and also why running produces so many important mental and physical benefits in a relatively short period of time.


The hard work aspect of running is why I frequently return to the mind and motivation. It’s not the size of your heart chambers that makes you a good runner, or the length of your legs, or the diameter of your calf muscles.


It’s your brain. The brain is what motivates you to continue running even though it’s hard work.

You can never put too much emphasis on brain-training, because it’s what gets you out the door (or onto the treadmill). We all need to master every get-going trick in the books to make sure we keep on keeping on.


Here’s a concise article that nicely summarizes 8 great tips to focus and improve your motivation. 

I particularly like the last of them: “Set Mindful Intentions: Connect with Your Purpose.” I try to do this before every run, but I also use the other 7 tips as well. The whole is greater than the sum of the parts. More at Sport Coaching.


Why your kids (or grand-kids) should start running

We often focus too much on the relatively short term. I mean, I get it. Everyone wants to run a strong marathon--or other personal favorite distance--this fall or next spring. (And I definitely fall into this group.)


But the long-term is more important and carries greater potential payoffs. Lately, at various social gatherings, I’ve been showing off by saying “intergenerational epigenetic metabolomics” a lot. This is way outside my wheelhouse, but I know it can refer to exercise benefits that are passed from one generation to the next--that is, from mother/father to child.


Similarly, on a slightly shorter term, your midlife fitness affects your late life health. This is one of the most important reasons to resist weight gain and exercise regularly as you age from 40 to 60.


A new study also provides concrete data to support the importance of youth fitness to lower adult cancer. Using a Swedish military-conscription registry (all male), researchers divided more than 1 million subjects by their “cardiorespiratory fitness in youth.” During the next 33 years, more than 84,000 of these individuals developed cancer. 


Those who had shown high fitness at the study’s beginning had a 5 to 40 percent lower risk of 9 site-specific cancers (like lung cancer, stomach cancer, colon cancer, etc) than low-fit youth. Conclusion: “These results strengthen the public policy-making incentive to promote health through improving cardiorespiratory fitness in youth.”


Important notes: High fit youth were 7% more likely to develop prostate cancer, though possibly not the most aggressive prostate cancers. Also, they had a 31% higher risk for malignant skin cancer, a well known issue for outdoor exercisers. More at British J of Sports Medicine with free full text.


Can we solve the riddle of performance breakthroughs?

The future of training breakthroughs is … cloudy with occasional periods of drizzle and fog. Even when performance breakthroughs do occur, we’re often not sure why they happened. Here Alex Hutchinson refers to a paper I mentioned several weeks ago. It’s a survey of top sports scientists who were asked the question: Where are future breakthroughs going to come from?


Hutchinson touches on the big themes that were mentioned--high-tech assistance, better use of altitude/heat/nutrition, etc--but becomes more interesting when he reflects on his own thinking. When a new approach is clearly beneficial, he observes, we know it’s working because the results are everywhere obvious. For example: super shoes.


But when something provides a lesser boost, or none at all, we waiver on its value because the results are difficult to perceive on a wide basis. Think: ketones, nose strips, heart rate variability, and many more. As Hutchinson writes, “Every time I start to get too enthusiastic about the performance-boosting power of new technology, I remember that a disproportionate share of the world’s greatest distance runners still come from East African countries where sports science isn’t a high priority.” 


In endurance practice, we do well to stick to the simple, proven basics of training, nutrition, hydration, recovery, and sleep. When it’s time to try something new--shoes, for example--you’ll figure it out soon enough by listening to other runners. 


Fifteen years ago, barefoot/minimalist shoes were all the rage, especially beloved by media types eager to write/video about something new. But minimalist shoes never reached the point of widespread adoption by serious runners. Whereas with super shoes, we’re looking at a massive, generational breakthrough. Vast numbers of runners can see and feel the difference. The performance-improvement scale has clearly dipped in their direction. More at Outside Online.


No fear: Flat feet aren’t the disaster you’ve been told 

Breathe easy, all you flat-footers. It seems that sports/podiatric science is ready to release you from Purgatory. 


Not long ago, you were advised to wet the bottoms of your feet and step on a piece of paper to produce a damp footprint. The outline of that footprint supposedly revealed your injury risk and your need for a certain type of running shoes. A high-arched footprint was mostly good. A low-arched outline not so much. It indicated that you had a high risk of injury, and had better buy a rigid pair of motion-control shoes.


Years later, research showed that this “wet test” had no power to predict injuries. Now a new Editorial in the British Journal of Sports Medicine contends that the continuation of articles from “the grey literature, professional websites, forums and other media still often suggest that flat feet are an important risk for injury or worse.” This situation “often results in unnecessary interventions for asymptomatic flat feet (eg, foot orthoses, motion control shoes), causing patients to become concerned.”


Instead, the authors argue that “flat feet should be considered as healthy anatomical variants.” This means it’s time “to abandon the outdated notion that having flat feet is problematic and makes individuals at high risk of musculoskeletal injuries.” More at British J of Sports Medicine.


A surprising way to maintain late-life strength

A key goal for a long, healthy life is to maintain sufficient vigor and strength in the late years. The opposite of this is called frailty, or sarcopenia.


Many older runners consume whey protein and other protein supplements to boost/maintain strength and fight frailty. It turns out another common but surprising food may also be effective: caffeine from coffee and tea. 


Chinese researchers followed more than 12,000 subjects for 20 years after they had enrolled in a health study at an average age of 53. Compared with those who drank no coffee/tea, those who consumed 4 or more cups a day had a 46% lower risk of becoming frail. 


There was a clear dose-response relationship, meaning that the more caffeine consumed, the lower the risk of frailty. Conclusion: “Higher consumption of caffeine at midlife, via coffee and tea, was associated with a reduced likelihood of physical frailty in late life.” More at J of the American Medical Directors Association with free full text.


If you’re worried about caffeine causing troubled sleep, theanine seems to neutralize the caffeine buzz that some find troubling. And tea, especially green tea, contains both caffeine and theanine. Therefore, it can reduce “the excitotoxicity” of caffeine to bring “a stimulating effect from caffeine and a calming or relaxing effect from theanine.” More at the preprint website QXMD.

Marathon training puzzle: Should you cross-train during your buildup?

We all know that the more miles you log in your marathon training, the better you’re likely to run on race day. That’s good news for the well-disciplined. But it’s also widely believed that cross-training is a great way to get strong and healthy.


The problem? Assuming you’re not a fulltime, professional runner, how do you achieve both in a real-life world that places many demands on your time? It’s one of those eternal training questions.


The below article digs into the issue, providing a solid list of PROs and CONs. It even rounds up a few scientific studies, though none are specific enough to resolve the conundrum.


Which sounds like this in every-day terms: I’ve got 5 hours a week for my marathon training. Should I do running workouts only, or should I mix together running and cross-training?


Like I said, a good and eternal training question. This article concludes: “Cross training can be a fantastic complement to your marathon training program, enhancing your overall fitness and reducing the risk of injuries. Remember, moderation is key – don’t overdo it with cross training to the point where it hinders your running progress.”


If I were forced to vote, I’d opt for running-only for the last 8 weeks of your marathon buildup. Try to run 4 to 5 times a week, and take good recoveries on the days when you can’t run. 


After your marathon, ease back into a mixture of running and cross-training. A concentrated period of run-training is the best way to prepare for a marathon. A balanced program of running and other activities is the best way to lead a long and healthy life. More at Sport Coaching NZ.


Eliud Kipchoge’s secret core-training device

I thought I had finally unlocked the key to Eliud Kipchoge’s amazing two decades of world-beating excellence. He’s a big core-training proponent! Indeed, in the photos at the below link, he seems to be using a revolutionary new device the rest of us have never seen.  


Then I looked a second time. And a third. And I finally realized I wasn’t looking at a hush-hush new gizmo. 


In fact, Kipchoge was walking around his training camp while holding a small bedside table. The table was turned upside down so he could grasp the underside, and fill it with various odds and ends from camp. The more junk on the table, the greater the total weight, and the more effective the core-training effect.


No, Kipchoge doesn’t sit atop the globe because he’s got more high-tech doodads than anyone else. These days, the rest of us even have shoes and drinks like his. Kipchoge’s secret is 20 years of consistent, unrelenting training with great attention to detail. More at Twitter/Eliud Kipchoge.


What makes super shoes “super”--the plate, or the foam?

Here’s a study that was funded by Saucony, but the company wasn’t trying to prove its shoes superior to others, so we can read the results with an open mind. In this case Saucony asked a topnotch independent researcher to answer a question we’ve all been wondering about.


What’s putting the “super” in super shoes? Is it the stiff midsole plate, often made of carbon fiber? Or is it the miraculous new midsole material, often Pebax? This is a question runners and scientists have been seeking to answer since super shoes first reached the mass market.


Here, veteran super-shoe researcher Wouter Hoogkamer tested runners in 4 different Saucony shoes with these characteristics: A) a carbon plate and super foam; B) a carbon plate with a traditional EVA foam; C) super foam but no plate; and D) an EVA midsole and no plate.


The test subjects were 14 “trained runners” who ran a number of different 5-minute trials in each shoe on a laboratory treadmill while their running economy was measured. Then Hoogkamer et al compared the results on a shoe by shoe basis. 


And the winner? If you guessed carbon + foam, you’re right. The runners performed best in these modern-day super shoes, which appear to remain the gold standard for racing. The runners performed worst in the EVA shoes with no plate.


The inbetween shoes with either a plate or super foam finished … in between, in a virtual tie. They were better than the last-generation EVA shoes, but not as good as plate + foam combined. 


These variations are becoming more important in the consumer marketplace, as shoe companies add more shoes at more price points with either stiff plates or super foams, but not necessarily both. As usual, we runners will have to try the various products to see which perform best for us during different types of training. 


Conclusion: “Changing EVA to PEBA superfoam or adding a plate both improve running economy by a similar amount, 1.3%. However, both changes combined result in less improvement (2.1%) than the sum of their parts.” More at Footwear Science.


Endurance boost or myth? The scientific truth about nose breathing

A widely circulated photo created quite an Internet sensation last week. It shows top tennis pro Iga Swiatek practicing with her mouth taped over. Fans of nasal breathing took this as proof of their favored technique even though Swiatek said, “It’s harder to breathe when you’re only breathing through your nose.”


Okay, but does nasal breathing improve your endurance? The Washington Post (subscription required) found some physiologists who agreed with this method, but most experts pooh-poohed it. This was especially true of Nick Tiller, an ultramarathoner and respiratory function PhD. He compiled a list of six key studies in the field.


In sum, the research indicates that nasal breathing can sustain modest to intense exercise, but there’s no advantage to it. Most athletes find it more natural to use “oronasal” breathing (mouth and nose combined) during hard efforts. More at Twitter/NickTiller.


Optimizing your recovery: Make sure your easy days are doing their job

We distance runners tend to use terms like “recovery run,” “easy run,” “cross-training day” and even “day off” rather loosely. It’s evident that these days are meant to follow days that were harder and/or longer than normal, but the specific hows and whys are often less clear.


Here coach Andrew Simmons explains his philosophy on recovery runs along with the specific nuts and bolts. He believes recovery runs should last just 20 to 30 minutes to remove metabolic waste without incurring more body stress. If you’re feeling particularly fatigued, you can choose “passive recovery” which could include massage. Or maybe you’d prefer really passive recovery--a nap. 


Either way, make sure that your recovery day is actually that. And not just another piling-on-the-fatigue day. That path leads to a deadend or worse--a falling off the cliff.


Interesting note: Simmons sides with recent studies adding fuel to the thought that women may need less recovery than men. More at Training Peaks. 


Arthritis myth debunked: Marathon running doesn’t cause knee/hip issues

Here’s more good news concerning the old wives’ tale about running and knee/hip arthritis. It comes from the medical team at the Chicago Marathon. Over a several year period, they surveyed 3804 Chicago participants. 


The researchers were particularly interested in debunking the “current dogma” that running causes arthritis, so they asked not just about arthritis pains, but also about age, years of running, mileage, lifetime marathons completed, family history, and so on. In total they posed 30 running-related questions to each subject.


The respondents looked like this: average age, 43.9; 52.2% male; 27.9 miles/week of running (with one outlier claiming 180); average pace, 8:52; 9.5 previous marathons (with one at 664); BMI, 23.8; years of running, 14.7. 


The paper didn’t report average marathon finish time, but we know from other data that this would be right around 4:30 (10:18 pace). Previous similar studies with marathoners have included much smaller numbers of usually more elite runners.


Results: Overall, just 7.3% of runners reported hip or knee arthritis, with 70% of these cases at the knee. After multivariate analysis, the researchers concluded that, as expected, a history of previous hip/knee arthritis or previous hip/knee surgery were strongly linked to joint pain and arthritis. Family history was also a strong predictor, as was higher BMIs.


Looking for the good news? There was plenty here. Increasing age reduced the odds for pain, but slightly increased the odds for arthritis. Sex was not a risk factor for arthritis, but did increase the odds for hip/knee pain. Higher weekly mileage and more previous marathons were linked to less pain. “Notably, neither the number of marathons completed, running pace, weekly running mileage nor the reported number of years running were found to increase the risk of hip/knee arthritis.”


Unfortunately, many general practitioners haven’t gotten the message, as a full 24.2% of runners in the study “who discussed running with their healthcare provider were suggested to either stop or reduce their amount of running.”


Most--caution: snarky comment forthcoming--didn’t listen to their doctor. A full 94.2% of marathon respondents told the researchers that they planned to run another marathon. And why not? They appeared to have little risk of pain/arthritis, and much opportunity to continue with a running lifestyle known to increase dozens of important health outcomes.


Conclusion: “From this largest surveyed group of marathon runners, the most significant risk factors for developing hip or knee arthritis were age, BMI, previous injury or surgery, and family history. There was no identified association between cumulative running history and the risk for arthritis.” More at Sports Health.


Ginormous study proves value of exercise vs cancer

Here’s a bigger than big analysis of the protective effect of exercise against cancer in studies including more than 30 million total subjects. Individuals who achieved about 150 minutes per week of moderate to vigorous exercise--the guideline recommended by many health groups--were 15% less likely to die from cancer than those not hitting the guideline. More at British J of Sports Medicine with free full text.


A separate paper garnered big headlines because it had a rip-roaring message: “You only need 3 minutes a day of exercise to lower your cancer risk.” Among more than 22,000 adults, those who engaged in vigorous leisure-time exercise for as little as 3.4 to 3.6 minutes enjoyed a 17 to 18% “reduction in total incident cancer risk” vs those getting no vigorous exercise. One more minute/day of vigorous exercise lowered the cancer to a 31 to 32% reduction. More at JAMA Oncology.

Lastly, here’s a deep, clearly written (by a physician) blog about exercise and cancer benefits. These include the use of exercise for patients who are rehabbing their health-fitness after cancer and cancer treatments. The blog notes that exercisers have an increased risk of skin cancer presumably due to time spent in sun. So watch out for that one.


Otherwise, just keep logging as many minutes/week as you can, and don’t forget that a few minutes of high-intensity exercise adds a little frosting to the cake. More at Dr. Scott Lear.
