Toe vs Heel strike: Injury Risk in Runners

When we observe runners, there are just so many variations in running technique and patterns. The length of the stride, body lean, amount of bending at each joint, the first point of foot contact and the arm swing are just a few of the places where we can notice the differences. Heel striking is one of the most criticised biomechanical variations in running. It is said that a heel to toe pattern impedes the forward motion of the runner and wastes more energy than landing on the forefoot. The first thing to get out of the way is that it’s not necessary that everyone who lands on their heel places it ahead of the body and that everyone who lands on the forefoot does so right under the body, which makes it invalid to connect the two factors. Forefoot Strike Technically there are three types of foot strike patterns: forefoot, rearfoot, and midfoot strike. The mechanics of the midfoot strike have more common features to the rearfoot strike and hence both of them will be considered under the...

Artifical Sweeteners: A Weight Loss Hack

Sugar has been around since centuries, and it looks like it’s here to stay. However since the ingestion of sugar was found to be responsible for fat deposition and has been linked with increased risk of lifestyle diseases, we have tried to find alternatives to it. Because, let’s face it. This is one addiction that has plagued the entire world in one swoop. Saccharin was the first artificial sweetener to be discovered, which was purely an accident. This is what led to the revolution to hunt the perfect sugar substitute. Artificial sweeteners were advertised as a very comfortable way to lose weight in the 19th century. It was used in sodas first, and later trickled down to other sweet foods and beverages. It promised to take away the calories from the sweetness making indulgence completely guilt free. This sounds too good to be true. After various research and medical organisations put forward their concerns regarding the safety of artificial sweeteners, the government imposed certain re...

Can You Lose Weight Through Diet Alone?

There are people who believe that exercise alone can help you lose weight as long as you don’t ‘overeat’. This view is evident by the sheer number of people who purchase gym memberships specifically for weight loss. Whilst physical activity is beneficial, there are a myriad of risks involved when people follow the advice of gurus who aren’t educated about the anatomy and physiology of the human body. At the other end of the spectrum, there are believers in nutrition who could swear by its effectiveness in weight loss. It’s easy to blame a particular macro, be it fats or carbohydrates. It’s much harder to back that claim with evidence. Does that mean we leave everything to chance and do whatever we feel is right? Absolutely not. Looking at the basics of nutrition content, a low carbohydrate diet has been shown to help with maintaining a low energy uptake, which in turn will reduce your weight (As carbohydrates and sugars are well known to be empty calories). Although fat was given a bad...

Resistance Training to Failure: Worth It?

Oh, how we all love to push ourselves to the very limit. When the last rep is moving slower than a snail. Yet we ask our spotters not to touch the bar, because ‘we got it’. We push on until the muscles burn and our heart rate is skyrocketing. It’s an exhilarating feeling. It gives us a sense of accomplishment and satisfaction to know we did our best. In addition to the feeling, many trainers also advise training to failure. The claim is that this results in a higher degree of muscle damage and thus greater muscle hypertrophy. It has been advocated by many lifters and bodybuilders as well. I hate to break it to you, but we might be wrong about this belief. Researchers have found that if the volume is equated, hypertrophy is greater for the people who do not train to failure. Volume is the total number of repetitions in a given time for a particular muscle group. This means if the same amount of work is being done, maybe with an additional set to make the number of repetitions in the wor...

Caffeine: Your Endurance Partner

Caffeine is originally obtained from coffee, which seemed to be discovered and put to use in Ethiopia in the 15th century. Coffee beans made their way around the globe through mysterious trade routes and a treasury of interesting stories. At this point, this super drug is commonly found in kitchens all around the world and enjoyed as a beverage by a large number of people. Caffeine was first extracted from coffee in 1819 and has opened up many possibilities by which it can be consumed. The cultural history is just amazing, but I wouldn’t attempt to explain the history for the sake of relevance. What we are concerned about is how the contents of this bean is critical to the performance of professional and recreational endurance athletes. At first glance, knowing caffeine’s effect on the heart rate, one would assume that it would not be beneficial to begin a long run with your heart racing before your feet get a chance to catch wind. However, this cannot be further from the truth. Caffei...

The Wonder of Unilateral Exercises

We always hear about how important movements like the squat, deadlifts, cleans are for lower body development, having a stronger historical foothold. In these, it’s generally about raw strength and power, and the topic of discussions in changing rooms, where people claim extraordinary personal records or targets.   Lifters are underwhelmed about unilateral (single leg/arm) exercises as a whole. We rarely hear people discuss about how amazing a particular lunge was for their gains. If we look at any isolated movement from a functional activity or competitive sport, it is almost always a unilateral one. Think about it. Running, jumping, vertical and horizontal leaps, changing direction, they are all predominantly unilateral. Granted, the weight on the bar while performing a split squat, lunge or any single leg movement isn’t anything to brag about, whereas the effects these produce on the overall strength and power is astoundingly comparable and is sometimes seen to exceed that of th...

On Dehydration: Athletes, Hold on to the Sipper

We can all agree on the importance of water in our bodies. Having an adequate level of hydration ensures optimum operation of the various systems of the body. Water content is also important for physical and mental performance in sports. Excessive water loss through sweat is very common in athletes, especially in endurance sports. Hence, every athlete, professional and recreational should be aware of this aspect of sports physiology. A dehydration of even 2% has been shown to significantly compromise physical performance and work capacity. This applies not only for endurance events like the marathon, but also for activities requiring strength, power, and high-intensity endurance. Dehydration has also been linked with impairing mental functions like attention, working memory capacity, reaction time, coordination, decision-making, and mood. The effects are experienced differently based on ethnicity, level of fitness, gender, previous hydration levels, and individual adaptation to environ...
