Powerlifting and weightlifting shoes have been around for quite some time and are used by elite athletes and recreational lifters. Stability and greater force production are something that is always talked about as an effect of using these shoes. Specialised weightlifting gear is often expensive, and shoes are no different. In this case, many lifters also use flat-bottom sneakers or a small weight plate under the heel. The reasons for the two alternatives are very different from each other. The flat bottom shoes are mostly used for stability, whereas the plate is used to elevate the heel. In this article, we will be discussing the effects of using weightlifting shoes or a plate under the heel while performing barbell back squats. We need to understand the reason behind using any form of heel elevation while performing squats. The most probable culprit is poor ankle mobility, because of which the athlete is not able to effectively move the knees ahead and then compensates by leaning for...

Almost everyone involved in physical exercise has experienced muscle cramps at some point in time. It can be explained as a painful and involuntary muscle contraction that locks the joint in place. They occur mostly in longer muscles that span two or more joints. Once experienced, athletes may continue to cramp unless adequate rest is provided. There are many theories as to how muscle cramps occur and what can be the possible solutions to relieving them. They are sometimes inaccurately termed as heat cramps. Exercise-associated muscle cramps do not have a relation with body temperature and do not recover with an external cooling modality, like an ice pack. If the theories of muscle cramps do not interest you, skip to the last part where you can learn how to deal with muscle cramps. One of the oldest theories is based on dehydration and electrolyte imbalance that occurs during exercise. It states that sweating alters the chemical balance of the fluids present in the body, which affects...

Caffeine as a naturally occurring drug has a very rich history. It has travelled around the world in mysterious ways through coffee beans. It originally required specified equipment to brew, but with the invention and popularisation of instant coffee, it has truly reached the masses. While many drink coffee and derived beverages for enjoyment, it has physical benefits too. Athletes and any other population can reap the performance boost that caffeine provides. The way in which it works is fascinating. Caffeine moves through the blood into the brain (only a few molecules are able to cross this barrier). Once in the brain, it attaches to receptor sites of the molecule called adenosine. Adenosine is responsible for the perception of tiredness and fatigue. Since caffeine molecules have blocked the sites, adenosine is not able to attach there and thus the feeling of fatigue is alleviated. This is exactly why people drink coffee to pull an all nighter before an exam. Caffeine has been found...

Not to be mistaken as a booty workout guide, this article aims to solve a physiologically important question. What we will be looking at is the amount of motor unit recruitment of the gluteus maximus that occurs with the particular exercise. Along with a few practical considerations, this should help us to pick the perfect exercises for the upcoming leg day. Gluteus maximus is supposed to be the primary hip extensor muscle group, which is found to be very important for strength and athletic movements like sprinting, cycling, jumping, and olympic lifting. Hip extensor strength is sought after by coaches to help improve the movements and sports mentioned earlier and also as a means to increase strength for performing compound lifts. The most popular exercises known by the masses for lower body resistance training specifically to target this muscle group are the barbell back squat, the barbell hip thrust and the Romanian deadlift. But as we shall see, it is not that obvious. Barbell Back ...

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...

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...

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...

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 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...

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...

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...

Are you losing weight for likes and comments on the transformation post that you would upload on your social media, only to regress a few weeks later? Do you want to just let it be; or quit the weight loss program? Of course not. Nobody will agree to either of these. Although reality paints a different picture about the adherence and dropout rates, despite fully knowing the risks and dangers of obesity. Adherence and compliance are crucial in successful obesity management. It refers to the behavior of an individual relative to the medical and professional advice including diet and lifestyle modifications, and physical activity participation. Many individuals don’t end up completing their journey. It’s not an easy process as it is, and a few additional factors make it worse. You might be wondering why are we talking about the negatives at all, but trust me. Knowing about the reasons will help you relate and understand that you’re not alone here. Mental stress, anxiety, body shape concer...

Workout accessories have evolved to include very niche products, the likes of which are probably never purchased or used by the majority. However, the weightlifting belt is one of the oldest and most popularly recommended and used worldwide. It’s not just the elites, but many recreational lifters swear by its efficiency. Some of the more common claims are its stability benefits, back injury prevention uses, and many claim that it helps them lift heavier. Today we will put these claims to the test by reviewing some research on this very subject. Firstly we need to understand the possible reasoning for the above claims. The stability aspect could be explained by the abdominal compression that the belt provides. It is often applied in a way that would squeeze the torso and this is thought to add to the natural intra-abdominal pressure that is generated by the core muscles. Next, the claim of reducing the risk of back pain comes from the physical support that it may provide to the lower ba...

We don’t usually see bodybuilders compete in the strongman or powerlifting competitions, but we immediately assume that a jacked-up guy on Instagram must be incredibly strong. Looking at lifting videos of the 8 times Mr. Olympia Ronnie Coleman makes me think: Does size and strength really go hand in hand? For you to be strong, must you also have to look that way? What about the other way around — Does a muscular, lean body translate to tremendous strength? This has been a topic of discussion going back a few decades. Today we’re a lot closer to answering the above questions. Let us quickly get through the basics. Hypertrophy is an increase in size of, in this case muscle tissue. This can be of various types, since muscle is made up of protein and fluid. There can be an increase in protein mass, or volume (which includes fluid). Technically speaking, myofibrillar hypertrophy, or connective tissue and sarcoplasmic hypertrophy. Strength on the other hand is the functional nature, which de...

Urbanisation comes at a cost. With the development of infrastructure, we have lost many dirt roads and trails. We humans have been running since the beginning of our evolution, but the surfaces on which we run have drastically changed in a short span of time. Dirt trails, natural gravel and grass have been replaced with concrete and tarmac. It is needless to say that we still have access to dedicated mud and (synthetic) tracks. You might also find a hilly trail near your house. What is undeniable is the fact that it’s not as easy as it was. We will talk about treadmill running in another article. Let’s focus on grass, synthetic track and concrete for now. Another noteworthy point is that the injury risk depends on various other factors like the running technique, type and intensity of running, the distance covered per week, the stride length and frequency, type and material of shoes, landing patterns, amongst others. So for now, we will be strictly looking at the surfaces to see which ...

Soreness, micro-tears, and the burn! We hear these terms a lot in the weight room, though a lot of people aren’t sure exactly what these things indicate. Yet the same individuals advise about the desired intensity of exercise and casually throw the words around. We must have all felt sore at least once in our lives and are probably not excited about the sensation. How many times have you been told to aim for soreness while you’re at the gym? Have you felt proud to experience soreness, like it is proof of your efforts in the weight room? Is soreness the target if you want to achieve muscle growth? These questions are not thought about enough and seem almost obvious to many people. Speaking of soreness, it is the sensation of muscle discomfort felt as a result of muscle damage and can be induced by exercise. It is more prevalent after performing eccentric (negative) focused exercises, or when one is unaccustomed to that particular exercise form. It is an indicator of incomplete recovery ...

Low back pain is very notorious and can strike at unexpected times. What’s mysterious about it is that the activity that triggered the pain might seem normal to you. It might be something as simple as bending over the sink or trying to pick a very light object. On a few occasions, the pain can be so severe that you aren’t able to think of anything else. You might also be reluctant to move from any position in fear of increasing the pain suddenly, let alone be productive. Experiencing numbness, tingling, or lightning pain traveling to one or both of your legs is not rare, but needs to be noted. Before getting at what causes these symptoms, we need to see what to do if you ever experience this pain. First and foremost, calm down. Whatever the mechanism of pain is, understand that this pain will reduce when given adequate rest and appropriate movements according to the stage of recovery. Try to find movements that reduce the pain. For some it might be sitting, for some lying on the side w...

The world is tired of hearing doctors’ advice for weight management, even if it is true. Many know of its seriousness from within. Moments before stepping on the scale, the majority of us feel nervous, anxious, and even terrified to see the number it would display. We start recalling all the instances where we picked up an extra serving, didn’t plan our meals, and ordered takeout. Here is some tough love coming your way. It has been known for decades that being obese or overweight increases the risk of other diseases like diabetes, cancer, and coronary heart disease. It also alters biomechanics and increases the load on joints while even performing daily activities like walking and stair climbing, which in turn increases the chances of injuries like ligament sprains. It can even cause you to suffer from early osteoarthritis. Not surprising that patients with this degenerative joint disease are medically advised to manage their weight. It also takes a toll on respiration, by causing exe...

Long before Christiano Ronaldo refused to promote Coke and claimed the superiority of water to the world in front of the press at the Euro 2020, we knew about the calorie-dense nature of sweetened beverages. Despite providing no nutritional value to our diets whatsoever, sodas and soft drinks continue to be in high demand almost everywhere. Most of its credit goes to shrewd marketing and obviously to global sugar addiction. A can of coke contains roughly 130 calories, whereas water has none. To expend just one can’s worth of energy, one would have to run for 15 minutes. That will help only if you don’t make poor diet choices again on the same day. It should be obvious that avoiding the consumption of sweetened beverages would help you lose some weight, and you might have already been advised to do so on numerous occasions. It’s a no-brainer that replacing these beverages with just water would reduce the total energy consumption in a day and thus help you to put yourself in a calorie de...

It's prevalent to encounter lifting advice in the gym. This one is as old as it gets. Let's examine it and see if it is a myth or a scientific truth. In my opinion, the squat is the godfather of all the lower body exercises. It has numerous variations and is an exercise that, once perfected for an individual, can be overloaded very effectively. It’s relatively safe to perform, with some equipment like the safety bar and the smith machine amplifying this quality. Although being a fundamental movement that is so essential to us even in our daily lives, there are many misconceptions around it which I need to face as a healthcare professional and a lifter. Somebody once decided that the knees going past the toes is apparently harmful and risky for the knees. Rationalisation was provided on the basis that this will limit the compressive stress and tension on the tendon of the quadriceps muscle, which in turn should prevent the inflammation of the tendon and knee pain. Even large res...
