 Q - Coach, I'm doing intervals on the treadmill these days. Do you know of a tool that converts interval l times in to mph or kph or minutes per mile? I'm not great with math. A - Offhand, I don't know of such a tool, which is why I recently created a spreadsheet tool for one of my clients. You can try it out HERE.

 Q - My son just bought an elliptical, and he asked me how it compares to running. Do you know how to compare for instance a 5 km elliptical workout to running? A - Thanks for the question. Obviously, the image above gives away part of my answer... Elliptical Design Considerations You didn’t tell me the type of elliptical you have and as I’m sure you’re aware, there’s quite an array of model designs (e.g., elliptical trainer, elliptical glider and elliptical cross trainer) which result in different stride ranges and knee angles. And they may or may not have moving arm bars. My personal design preference, is one like the Life Fitness 93x (image below – and no I’m not sponsored). I find it simulates the feeling of running on the flat in terms of the stride length and a relatively low arc. For the most part, I don't use the movable arm bars so as to put greater effort on the legs.  For me, the angle at the knee feels similar when running on the flat, since during landing, weight bearing and push off, the angle is small. And you can use your hamstrings to pull the foot platform back in a similar fashion to running rather than just focusing on the downward push. After all, when running you are basically pawing the ground behind you while at the same time applying a downward force. However, the models that do produce much greater knee angles can be used to more effectively target the muscles used for uphill running. Treadmill Designs As for treadmills, basic designs are not as variable, as the majority of models at fitness facilities, simply offer controls for varying slope and speed. While it’s relatively common in clubs to find a high-end treadmill with an incline option, rarely will you find a model that simulates both uphill and downhill running. But they do exist and can offer 10 to 15 percent uphill and 2 to 3 percent downhill slopes. HERE’s a link to a Youtube video showing a treadmill that offers such inclines. The decline option would certainly be of benefit for those training for downhill courses like the Revel, or St. George, or Boston marathons (see HERE for more on downhill running.) And more recently, some high-end clubs have added futuristic-looking curved sled treadmills as an additional way to beat yourself up in some high end clubs.  Curved sled treadmill Anyway, let’s check out what those dogged exercise physiologists have observed in two studies.

Are there any downhill marathons that are ok to use to qualify?  A - Well, you certainly aren't alone with this dream. After all, Boston is the most famous marathon in the world being one of the oldest (this year will be the 122nd), and having been patronized by many top runners of the day. And the fact that you have to qualify to partake makes it even more of a special badge of honour . (BTW, Boston was my first marathon, and I've shared some memories of it in one of my Audios HERE.) Years ago you didn't have to formally qualify. Those were the days when Canadians were especially welcomed…at least we thought we were. After all, 12 different Canadian heroes have won the event, including Gerard Cote, who won it an amazing 4 times between 1940 and 1948, Canadian record holder, Jerome Drayton, the 1977 winner, and a woman, Jacqueline Gareau, in 1980, who was almost upstaged by the infamous Roise Ruiz. . And speaking of big names would you believe the name of the Canadian dude, who won the 2nd Boston Marathon in 1898 was named Ronald MacDonald (no clowning around him….I know the spelling’s not quite the same.) Qualifying Standards Introduced Anyway, in 1970, the organizers in an effort to keep the number of participants to a manageable size, introduced (but not that rigidly enforced as no verifiable proof was needed) And they even allowed a grace of 59 seconds; but that was curtailed in 2013. But more recently, qualifying has become even more challenging as organizers have put a ceiling on the number of participants per age category; so that achieving the qualifying time isn't necessarily good enough, which can be more heartbreaking than Heartbreak Hill. Heartbreaking Story Case in point: in 2015 I had a client who's goal was Boston and the qualifying time for her age category was 3:45. Her training went well and in a fall marathon she joyfully exceeded the standard running 3:41:56. Unfortunately, too many others ran faster and the race organizers made the cutoff 3:41:52. She couldn't run. Desperate Measures As a consequence, I'm finding more like you are looking for marathons that offer the best chance of good weather (always a crap shoot) and a favourable course. In fact, several years ago I had a client ask me your same question, and I told him about the St. George Marathon which at the time had, and still has, a reputation of being one of the fastest courses In North America. Why? Because it Starts at an elevation of 5240 ft. (1597 m.), and finishes at 2680 ft. (817 m.) – that’s an average decline of 18.5 m./km. and the overall average slope is 1.8%.  But Does It Count? One might ask: if a course is so dramatically downhill, will a performance count? Good question - In fact, the IAAF (International Association of Athletics Federation) stipulate very stringent criteria in order for a course to be deemed eligible for World Record purposes. You can see all of the 5 criteria HERE The 2 pertinent criteria for your question are: “(b) The start and finish points of a course, measured along a theoretical straight line between them, shall not be further apart than 50% of the race distance. (c) The overall decrease in elevation between the start and finish shall not exceed 1:1000, i.e. 1m per km (0.1%).” Now, even the Boston Marathon route fails to abide by both of these criteria . As regards elevation, Boston starts at 476 FT. (145 m.) ASL and finishes at 16 FT. (5.m.) for an average decline of 3.31m./km., and the straight line distance from the Hopkinton Start to the Finish is 38.6 km., which far exceeds 50% of the race distance.

Q - Coach: I recently read an online mag called ScienceMag that was promoting a product called The Density Blanket it says is engineered to be 10% of your body weight for Deep Pressure Touch Stimulation (DPTS), a proven therapy used to promote deep, restful sleep that anyone can benefit from. I'm a lousy sleeper especially before races, so am wondering if there is any truth to this and if any of your clients have used it. Thanks. A - I admit that until your question I was unfamiliar with this product; and I don't know any runners or anyone for that matter who has used them. So I've looked in to it... I'll tell you one thing I've discovered - weight blankets are big business! Just do a Google and you'll see what I mean. I should point out that ScienceMag is not a scientific periodical - rather, it's an advertisement aiming to sell product. In fact, If you scroll down to the bottom of the website link, you'll see the following: THIS IS AN ADVERTORIAL AND NOT AN ACTUAL NEWS ARTICLE, BLOG, OR CONSUMER PROTECTION UPDATE. But having said that, there is a heck of a lot of literature on the subject especially in the field of occupational therapy where it has been increasingly employed in acute mental health care settings for crisis intervention. And it's been reported that it appears to help the consumer nurture, soothe, and care for himself or herself and facilitate the ability to feel safe, comforted, and grounded in the world... just like a grilled cheese sandwich eh? Also, many other health-related professions, have used weighted blankets to assist children with an autism to be calm, fall asleep and remain asleep. The idea behind deep-pressure touch is that it stimulates the release of serotonin and dopamine, two neurotransmitters that tend to make people feel more relaxed. There are few scientific investigations. However, in 2015, there were a couple of studies conducted and published in the Journal of Sleep Medicine & Disorders: One was done in India entitled, Evaluating the Safety and Effectiveness of the Weighted Blanket With Adults During an Inpatient Mental Health Hospitalization. This was an exploratory, pilot study to investigate the safety and anxiety reduction of the standardized use of the 30-pound WB with 30 adults during an acute inpatient mental health hospitalization. The Safety measures included the Vital Signs of blood pressure, pulse rate, and pulse oximetry monitoring, with and without the 30-pound WB. Electrodermal activity and self-rating readings measured effectiveness for anxiety reduction. The results showed no statistical differences in vital signs indicating the Weighted Blanket was safe to use and the self ratings indicated 60% had a significant reduction in anxiety: but the Electrodermal readings were inconclusive. The other 2015 study was conducted at the Institute of neuroscience and Physiology, University of Gothenburg, Sweden and the published paper was entitled, Positive Effects of a Weighted Blanket on Insomnia. The aim of the study was to investigate the effects of a chain weighted blanket on insomnia, using objective and subjective measures. 31 completed the protocol (11 men, 20 women). Objectively, it found that sleep bout time increased, as well as a decrease in movements of the participants, during weighted blanket use. Subjectively, the participants liked sleeping with the blanket, found it easier to settle down to sleep and had an improved sleep, where they felt more refreshed in the morning. The investigators concluded that a weighted blanket may aid in reducing insomnia through altered tactile inputs, and thus may provide an innovative, non-pharmacological approach and complementary tool to improve sleep quality To the investigators credit the paper did have the following footnote: CONFLICT OF INTEREST The study was supported by a grant from Somna AB. GB[one of the authors] is the Medical Director of SDS Clinic, where the study was overseen. So where does that leave us? Certainly studies are needed in order to study the physiological impact once folks have fallen asleep. Personally, I do like the feel of a thick duvet vs. an usual blanket. And I was recently a guest where I experienced a Portuguese blanket that was far heavier than my duvet but far less weight than 30-lb. and I had a wondrous sleep......zzzzzzzzzzz ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ For additional information on this topic I suggest you read an article that was published in LiveScience in May 2017 entitled Weighted Blankets: Harmless for Adults, Potentially Dangerous for Kids. Q - Coach - I see you've been measuring several of road race routes this year for certification purposes. I've run in several races and wondered how accurate they are. Is there a site that tells you if a course has actually been certified. A - Yep - in Canada, Athletics Canada is responsible for granting Course Certifications and they post the routes that are certified HERE. There you'll see the listings that look like this:  In fact, the majority of road races are not certified, and for your interest, the magazine, Canadian Running, did an article about this subject last fall - you can read it HERE. Occasionally, a route that has been certified may not yet be posted to the Athletics Canada website; so, if it's really important to you, I suggest you contact the Race Director for confirmation, unless of course it's concerning a route where you ran a PB :) Q - Coach, this past week I read a New York Times article. It was about a woman who after a spin class experienced a serious condition called Rhabdomyolysis which I’ve never heard of.
Apparently the woman's legs throbbed with excruciating pain, her urine turned a dark shade of brown, and she felt nauseated. And she he ended up in the hospital. The article didn’t say anything about runners, so I’m wondering if you’ve ever heard of it. And so does my non-running wife who unfortunately read the article too... A - I am aware of this condition., Rhabdomyolysis is a condition in which damaged skeletal muscle breaks down and some of the breakdown products, such as the protein myoglobin are harmful to the kidneys and may lead to a potentially dangerous kidney failure. It's also a very tough word to use in scrabble... By the way I did read the July 17 article you're referring to. It was titled "As Workouts Intensify, a Harmful Side Effect Grows More Common". Here's a link to it. This condition is not new and has been scientifically investigated with runners as far back as 1978 - see HERE. But it happens so rarely. In fact in over 4 decades of associating with runners and clients, not once I have encountered it directly or indirectly. If you (and your wife) need reassurance, check out this 2007 study of runners which over a 6 year period only observed 7 cases of runners who experienced the condition and all recovered: HERE For a really in depth review of this subject, you can check out this very lengthy review published earlier this year (2017) HERE Q - Coach - I had a strange thing happen to me last week after my long run. It was a hot day but soon after I finished my run I began really shivering. It was a first for me. Is this a worry?  A - Actually this is not an uncommon physiological phenomenon Granted, it does seem somewhat paradoxical that it might occur after a run in warm temperatures.
I refer you to a good article published in 2012 by the highly respected magazine, Scientific American. The article provided a very readable explanation. The article is entitled “Running and thermoregulation: the post-run "shivers". and a link to it is HERE. And here’s an excerpt from the article which is over 1,200 words long, but as I say, is quite an easy read. "When I stop running, the heat loss and sweating will stop fairly quickly. But remember, my core temperature is still elevated. This means my skin temperature, though I won't be sweating, will remain high and I'll still lose some heat to the air. And because my heat production is down (I'm not running anymore), my heat loss is going to be greater than my heat production. At first, this is good because my core temperature is a little elevated, and this will lower my core temperature. As long as I don't lose heat too quickly, Everything will go back to normal. But in my case, I may lose heat too quickly." Rest assured that this is a common phenomenon, and I would say a 10 to 15 minute mildly warm temperature shower should take care of it. Q – Coach, I’ve noticed a lot of hockey players in the NHL are inhaling smelling salts before the start of games. Just wondering if they might be good for distance runners. I haven’t seen any of the elite runners at the big marathons using, but just wondering what your opinion is. A – Funny you asked this because last night I particularly noticed the super rookie Leaf player, Auston Matthews, taking a whiff of the salts. BTW, Leafs lost the game to Columbus…. First, let’s be clear of what we’re discussing. Smelling salts, also referred to as ammonia inhalants can come in packets about the size of small tootsie rolls. The usual active compound is ammonium carbonate and when released causes the muscles that control breathing to work faster.  Vial of Smelling Salts Traditionally they've used to revive consciousness after fainting or on boxers,. But this is no longer recommended and in many sports is banned because it may inhibit or delay a proper and thorough neurological assessment by a healthcare professional Use by Hockey Players The subject of it’s fairly common usage by NHL hockey players has certainly been publicized in the print. In March 2016 there was a Sports Illustrated article (see here). And in 2014, the New England Sports Network (NESN) published a very funny article that included a GIF showing Phil Kessel’s reaction to inhaling the product (here).  Phil Kessel reacts to a whiff The author of the SI article, which included comments from some of the players and a coach summed it up: “So, at most, it provides a temporary boost and perhaps a slightly longer placebo effect, depending on the individual. Coyotes veteran Shane Doan, who, according to the article, says he hasn’t used them in three years, compared the experience to a quick window wipe at the gas pump, flushing out eyes weary from the road or the rink’s fluorescent lights.” Use by Runners ? You"ll often see track sprinters slapping themselves on the legs or face before the start of a race, with the aim of arousing themselves for the very intense effort ahead; but I've never seen a sprinter use smelling salts in the final moments before going to the blocks. One might think that sprinters would be apt to employ the salts but then it’s very important for the sprinter to be calmly focusing on responding to the starter’s instructions and reacting to the gun; so taking a whiff of salts just before going to the blocks might risk undermining this process. And as for the long distance runners, there's a huge difference between a hockey player's 40 second shift and a 40+ km. marathon lasting hours.That you haven’t seen any of the top marathoners imbibe is a strong indicator that the salts are not deemed to enhance performance. After all, as has been demonstrated coaches and athletes are forever exploring anything that might give an edge. Besides, the last thing you want to do is get over aroused risking too fast a pace in the beginning. In fact, the only item I’ve come across is some lay speculation that the woman’s gold medalist in the 2008 Bejiing Olympic Marathon, Constantina Tomescu-Dita, of Romania, at age 38, may have inhaled smelling salts in the latter stages of the marathon (see here), but I haven’t seen any verification for this. BTW, it's not and illegal substance.  Constantina Tomescu-Dita Scientific Evidence I’ve scoured the scientific literature and I’ve only come across two recent studies on this topic: The first is a student’s Master thesis study conducted with young (early 20s) men and women at Old Dominion University, in Norfolk, Virginia, entitled, The effects of pre-maximal exertion inhalation of ammonia and the performance effects during deadlift maximal tests (abstract here). And the conclusion was that within the limitations of this study, there is no basis for the support of ammonia inhalation to improve 1-RM efforts in training, competition, or any other circumstance.  Deadlift The second study was in New Zealand entitled, Cerebrovascular, cardiovascular and strength responses to acute ammonia inhalation (abstract here) . Fifteen healthy males completed two trials.Trial one investigated cerebral artery blood flow velocity, heart rate and arterial pressure response to ammonia inhalation. During trial two, participants performed a maximal single mid-thigh pull (MTP) .  Mid-thigh Pull Despite the marked cerebrovascular and cardiovascular response to ammonia inhalation no ergogenic effect was observed during the MTP, irrespective of the timing of administration. Given all this, I have to give the idea of distance runners using smelling salts a...  Q - Coach: I'm a runner (half marathon PB of 1:50). In late March I was playing soccer with my son and badly hurt my hamstring when I stepped on the ball and fell awkwardly. It's taking me awhile to get back to the running and my one leg feels weak. Do you have any suggestions? A - Sorry about your mishap...Kids... But your question provides with me a good excuse to deal with a related situation that might be of some help to you: All car owners appreciate the importance of insuring their car's wheels are equally inflated and balanced. The consequences of this not being the case are uneven tire wear, ride bumpiness, and side pulling.  Well, I say the same is true for runners, and suggest that if one leg is stronger than the other, it may result in dominance, resulting in an uneven, less efficient stride. And if this continues, the discrepancy may become magnified and theoretically increase the susceptibility to injury. Does that not make common sense?… after all, if you were to build a robotic runner would you build it asymmetrically? I don’t think so…. Engineers don’t design symmetry in planes, cars, etc., for no reason. CAUSES Why a strength imbalance might exist in the first place may be due to a number of reasons such as:
SO HOW DO YOU KNOW? Most runners have no clue as whether they are evenly strong. Understandable. Determining whether a strength imbalance exists is not as obvious or easy as dealing with a car where you can simply pull in to a gas station and inspect the tires for uneven wear and check the tires' air pressure. For runners the symptoms may not be so obvious, and in the early stages be hardly noticeable, if at all. HERE'S A CASE STUDY A couple of years ago a client told me in the interview that a year previously she had severely sprained her right ankle. She had been unable to run for 5 weeks but then resumed easy running, and over the next couple of months she gradually built up to her normal previous distances. However she was frequently having new aches and pains in other areas of her legs that would become intolerable and at times cause her to take several days off. Despite the discomfort, she said was able to continue running (how many of us have been so guilty?). [Note - I have previously dealt with the perils of running when a discomfort is present - see here.] In search of a possible cause, this client agreed to my suggestion to have her strength balance tested. HOW TO MEASURE Now to effectively determine if strength imbalances exist, I recommend accessing a fully equipped fitness centre and that you have a coach or trainer serve as a tester in order to insure objectivity via blind testing. By that I mean, the person being tested should not know what weight (or # of plates) are being used for the various measurements. And the tests employ single leg exercises for both legs. And by the way, in the many years of working out in gyms I have rarely observed folks doing single leg exercises as a part of their routine, even when being supervised by a personal trainer. Admittedly, it does take a little more time. Now the exercises I use for the testing, which don't need to be done all in one session, are shown in the gallery of images, below And many thanks to a great website, Ex.Rx.net, which I strongly recommend, for the following GIF images. Position your cursor over the image and click to see an animation of the movement and description of each of the exercises. CAUTION To avoid hurting yourself while performing the tests, it’s extremely important to warm up before the testing by doing 10 minutes of easy to moderate effort running, or biking, or elliptical, as well as 3 or 4 reps of each exercise with increasing weights leading up to the maximal efforts. Also, the testing should only be done if there is an absence of any muscle discomfort. THE MEASUREMENTS I measure 2 aspects: 1) maximum weight that can be handled for 2 reps (an indication of basic strength); 2) the number of repetitions for 1 set with about 75% of the maximum established in (1) ( an indication of endurance). HOW TO CORRECT ANY IMBALANCES Now, if the measurements reveal strength differences, and in the case of this woman, as an example, there were very significant differences, I strongly recommend you use weight training which will enable you to objectively know for a fact the number of kg. or lb. being moved. How so? I recommend 2, or, ideally, 3 sessions per week, working with 3 sets of 10 to 12 reps. exercising the legs separately. So, for each of the single leg exercises, do 3 sets with the weaker leg first to determine what it's capable of - striving to achieve higher rep and/or higher weights. Whatever number of reps the weaker leg does, you simply match it with the stronger leg and then stop when you reach that number.So you are content to maintain the stronger leg's levels until the weaker one “catches up”. This single leg approach admittedly takes more time but once the muscles have evened up, you can go back to doing 2-legged exercises. However, every so often (e..g., 4 weeks or so) I would test again to see that you're still balanced. Returning to our case study, it took this woman just 8 weeks, weight training 3 times per week to even herself up and the annoying aches and pains cleared.   Q - What's the point of hill training?
A - Hill training is a form of "resistance training", meaning that the training causes your running muscles to contract at levels that exceed what they normally would when running on the flat - the resistance to propelling the body forward is much greater than usually encountered. Weight training is another form of resistance training. Thus the main reason for hill training ( typically running uphill for less than 60 seconds ) is to increase the power of the legs - increasing the springing forward capability. Increasing the power in turn increases the speed potential - after a hill training phase the runner can hopefully translate the increased leg power into an ability to running faster over 100 meters. And basic running speed is the ultimate determinant of running performance at any distance. For example, if you want to run a 4 minute mile (1,609.3 metes), you need to be capable of running about 30 seconds for every 200 meters of the 1,609.3 metres. Most of us can't run this fast - even for 200m - not because of our lungs, or heart, but simply because we lack the basic speed/leg power and/or coordination required. But common sense will tell you that just being able to run 30 seconds for 200 meters isn't going to be good enough because one can't sprint for an entire mile. In fact, to be capable of running 4:00 minutes for the mile you should be capable of around 24 seconds for 200 meters. As a matter of fact most of my clients are not limited in achieving there goals by basic running speed - relative areas of weakness are more typically Maximum Oxygen Intake and Specific Muscular Endurance. Hence their training programs may not require an emphasis on hill running whatsoever other than to incorporate hills during the course of their straight runs, which is particularly useful for preparing for races where the routes are hilly, e.g., Boston Marathon. There is another valid argument for incorporating resistance training in one's program and that is increasing the power (from hills ) and strength (from weight training) will help to reduce the ever present chance of injury since any given running speed will require the muscles to contract at a reduced percentage of their maximal capability. |
