The Barefoot running round-table discussion from UKSEM Thoughts from the Barefoot running round-table discussion at UKSEM: Many of you will probably know by now that at the recent UKSEM conference in London, I chaired a session called “Natural Running – advantages and disadvantages. A Round Table Discussion”. The protagonists in the debate were: Prof Daniel Howell, an anatomy professor from Liberty (USA), known as the “barefoot professor”Simon Barthold, who formerly worked as a podiatrist but who now works in biomechanics and is Asics global research consultantProf Benno Nigg, one of the world’s leading biomechanistsDr Mathias Marquard, a clinician and running coach (who would go on to become the voice of reason in many of the more hostile aspects of the debate, as I’ll describe!) The debate concept That’s a pretty high-profile “cast”, including some of the world leaders in their fields. Controlling it, however, was a nerve-jangling prospect. Buy or sell? So from my vantage point, this is what I saw from the five responses: Back to the debate…
Should athletes be allowed to use performance enhancing drugs? Julian Savulescu, Uehiro chair in practical ethics1, Leon Creaney, consultant in sport and exercise medicine 2, Anna Vondy, ST6 emergency medicine3 Author Affiliations Correspondence to: J Savulescu firstname.lastname@example.org, L Creaney email@example.com Stories about illegal doping in sport are a regular occurrence. Julian Savulescu argues that rather than banning performance enhancing drugs we should regulate their use, but Leon Creaney and Anna Vondy say this would lead to escalating use and call for tougher enforcement The zero tolerance ban on doping has failed. According to Hermann and Henneberg, “Using typical values of detectability . . . the probability of detecting a cheater who uses doping methods every week is only 2.9% per test.”5 It is time for a different approach. Human nature It appears we reached the limits of human performance in sprinting about 15 years ago. Regulation could improve safety The strongest argument against doping is safety.
DC Rainmaker What we can learn from Olympians about staying warm outside The first in a four-part series on physiological extremes encountered by Olympic athletes. If swimming were a Winter Olympic sport, Lewis Pugh would be a heavy favourite. The 44-year-old South African adventurer has completed long-distance swims at preposterously cold temperatures in every ocean, clad only in a Speedo, goggles and swim cap. Perhaps the most extreme: a one-kilometre swim in icy, 1.7 C water at the North Pole in 2007, which he completed in 18 minutes and 50 seconds. None of the events in Sochi, Russia, will take place underwater, but all the athletes have to overcome some combination of bitter cold, cutting wind, snow, ice and sleet in training and sometimes in competition. Simply surviving the conditions isn’t enough: Numb hands or a chilled core can be the difference between victory and defeat. In general, your body strives to keep its core temperature around 37 C, in order to keep your brain and heart running smoothly. Or you can try Pugh’s method.
Running for Fitness Training to live with pain: What we can learn from Olympic athletes The second in a four-part series on physiological extremes encountered by Olympic athletes. The gold medal, we like to think, goes to whoever is willing to suffer a bit more than everyone else. So it’s odd that, when physiologists at the University of Wisconsin used spinal injections of a powerful painkiller to block lower-body pain in a group of cyclists, the cyclists actually got slower. They initially felt great and started out faster than normal, but then faded. Some of the most memorable Olympic moments involve athletes triumphing over pain: Silken Laumann’s improbable bronze in 1992, just 10 weeks after a horrific rowing accident; Slovenian cross-country skier Petra Majdic breaking five ribs and collapsing a lung just minutes before her qualifying heat in Vancouver 2010, then skiing through it – four times! “Pain is more than one thing,” explains Dr. For endurance athletes, pain at times seems like the central reality of their existence.

Training with 5 exercise heart rate training zones - page 1 Page 1 2 3 You may think that training is just for athletes. I absolutely believe that with few exceptions everyone can train to create change which leads to a good healthy life. Exercise is as different for everyone as Training With 5 Exercise Heart Rate Zones change is different. Whether you want to change by shedding a few pounds or you just want to feel good about yourself, then here's a way that, if you follow it, you may end up on the wellness road to a new life. What I'm talking about is Heart Zone Training, the best approach to all-around fitness I've found. This isn't a one-size-fits-all concept. Let's take it one part at a time and first look at those three words: Heart Zone Training. That's easy. A zone is simply a range of heart beats. Training is the regime of exercising to achieve a goal. Take my 58-year-old friend Sara whose young grandchildren are really paying attention to her workouts. You can have similar results. Heart rates are measured in beats per minute (bpm).
Why are elite athletes able to speed up when they see the finish line? The third in a four-part series on physiological extremes encountered by Olympic athletes. After five days and almost 250 kilometres of running through the shifting sands and hair-dryer heat of the Sahara Desert, Simon Donato had reached the limits of his physical endurance. The 37-year-old from Canmore, Alta., who travels the world competing in the most gruelling ultra-endurance races as co-host of the TV adventure series Boundless, knew he had to cover another 30 km to reach the finish line, but he could barely put one foot in front of the other. Then, as he staggered on, a strange thing happened: He began to speed up. Donato’s experience is hardly unusual. But it’s also puzzling. “Top-level athletes get closer and closer to their real physiological maximum,” says Dr. Marcora points to a classic study by French researcher Dr. Marcora believes our limits are dictated by an ever-changing balance between perceived effort and motivation. The difference, explains Dr.
Three strength-training exercises to improve stride length and frequency Walt Reynolds explains how to improve your speed by working on your stride length and strike rate. If you are an endurance runner, should you carry out regular strength training workouts? Not a single published scientific study has linked resistance training with improved 5k, 10k or marathon times, but running books and magazine articles extol the merits of strength training, and countless runners spend time in the weights room. Proponents of strength training for endurance runners claim that the activity bolsters muscle power, raises tendon and ligament strength, and lowers the risk of both acute and chronic injuries. To date, much of the research exploring the link between strength training and endurance performance has focused on standard exercises such as leg extensions and curls, leg presses, bench and shoulder presses. In fact, it is difficult to understand exactly how these standard resistance exercises would promote better endurance performances. The Power Triad Example Progression
What’s it take to perform like an Olympic athlete? It’s in the air (literally) The conclusion of a four-part series on physiological extremes encountered by Olympic athletes. Retired cross-country ski legend Bjorn Daehlie’s record tally of 12 Winter Olympic medals was matched last week by fellow Norwegian Ole Einar Bjoerndalen, who will attempt to dethrone Daehlie in the biathlon relays later this week in Sochi. There was much less fanfare two years ago, when Daehlie lost a more obscure title. Oxygen is the universal currency of athletic effort. Tests in the 1990s indicated that Daehlie had a maximal oxygen uptake, or VO2max, of 96 millilitres of oxygen per kilogram of body mass per minute. Identifying where the bottleneck occurs in this process is one of the most contentious topics in exercise physiology, with various lines of evidence pointing to the lungs, the heart, the muscles and even the brain. “These are the most fit people in the world, but their blood gas looks like someone who might present at an ICU,” says Dr.
Rules of Thumb for Running a Marathon (Marathoning Matters) Race pace. Training pace. Calories per mile. How much hot days slow you down. Over the years I've learned a number of rules of thumb about running marathons, covering everything from the impact of weight on performance to how running marathons impacts age and how age impacts running marathons. Taper and Race Day Rules of Thumb Taper your training so that you run no more than 85, 75, and 50 percent of your maximum mileage the three weeks before the marathon, respectivelyNever try anything during a marathon that you haven't tried in practice runs (eating Gu, drinking a sports drink, wearing different socks, shoes or shirts, etc.)Drink about 4 ounces of fluid per mile Basic Race Pace Calculate marathon finishing time as 2x a recent half marathon race + 6 to 10 minutes, go here for a simple minutes per mile pace calculator or use these rules of thumb Environmental Factors That Impact Race Pace Many factors will impact the above calculations, including going out too fast, heat, and humidity Weight
