Clothing-Accessories and its effect on myofascial pain

    Many researchers have published in detail about the Myofascial pain. While very less people have identified the external wears (clothing and accessories) and its impact on the Myofascial pain onset. It is proved that any restriction to the normal range of movement will produce the trigger points that are the key factor of the Myofascial pain.

    Myofascial pain can occur anywhere in the body while primarily concentrates on muscles and fascia. The Myofascial pain can cause a variety of symptoms ranging from muscular pains that are steady, aching, and deep to headaches, jaw pain, irritable bowel syndrome, painful periods, joint pain and tinnitus (to name a few). The intensity can range from mild discomfort to agonizing pain.

   There are certain clothing and accessories that can create or worsen Myofascial pain. To name some
1. Shoes
2. Tight jeans/pants/leggings
3. Tight fitting inners
4. Heavy side bags/purses
5. Wallet in the back pocket
6. Hair ties
We shall discuss and post about each in every single post elaborately


Fitness an introduction

Fitness is not just a leisure activity, it should be part of daily living.

Definition of fitness states it’s the ability of a person To do their daily activity without any stress and strain.



There are four major components of fitness.
Firstly, cardio respiratory endurance
Secondly, flexibility,
Thirdly, muscular strength,
Finally, muscular endurance.

All the four components are essential to be fit. No matter how strong you are if you are panting while walking or climbing stairs. Or with no muscle flexibility.

The next post will have the enumeration on all of the four individual components.

It has been long since the term “Illegal bowling action” being mentioned in the domestic and international cricket. However, people (General audience and the cricketers) are unaware about the exact meaning of it. If a person is flexing (bending) his/her elbow it doesn’t mean the action is illegal, while the extension (Straightening) of the elbow that exceeds the 15 Degree limit is called the illegal bowling action. As a part of ICC bowling action analysis team I (Vasanth Kumar) will be explaining the exact scenario that is categorized as illegal bowling action in the forthcoming publications from the ICC point of view.

Consuming fat turns you a fluffy, fatty person? That has been a question for decades. Does obesity really has anything to do with eating fats? Let us get a in-depth look at the fat, in addition to the proven research and the myths about the fat and what is the real culprit that really makes people fat.

What is Fat?

According to researcher fat is one among the three essential micronutrients (carbohydrate and protein) of human body. While, there is a misconception that fat intake makes people fatty and fluffy.

It’s time to end the low-fat myth. That’s because the percentage of calories from fat that you eat, whether high or low, isn’t really linked with disease. What really matters is the type of fat you eat.

Choose foods with healthy fats, limit foods high in saturated fat, and avoid foods with trans fat.

“Good” fats—monounsaturated and polyunsaturated fats—lower disease risk. Foods high in good fats include vegetable oils (such as olive, canola, sunflower, soy, and corn), nuts, seeds, and fish.

“Bad” fats—saturated and, especially, trans fats—increase disease risk. Foods high in bad fats include red meat, butter, cheese, and ice cream, as well as processed foods made with trans fat from partially hydrogenated oil.

The key to a healthy diet is to choose foods that have more good fats than bad fats—vegetable oils instead of butter, salmon instead of steak—and that don’t contain any trans fat.

The low-down on low-fat

“Low-fat,” “reduced fat,” or “fat-free” processed foods are not necessarily healthy. One problem with a generic lower-fat diet is that it prompts most people to stop eating fats that are good for the heart along with those that are bad for it. And low-fat diets are often higher in refined carbohydrates and starches from foods like white rice, white bread, potatoes, and sugary drinks.

When food manufacturers take out fat, they often replace it with carbohydrates from sugar, refined grains, or starch. Our bodies digest these refined carbohydrates and starches very quickly, causing blood sugar and insulin levels to spike and then dip, which in turn leads to hunger, overeating, and weight gain.

Over time, eating lots of “fast carbs” can raise the risk of heart disease and diabetes as much as—or more than—eating too much saturated fat.

So when you cut back on foods like red meat and butter, replace them with fish, beans, nuts, and healthy oils—not with refined carbohydrates.


Although it is still important to limit the amount of cholesterol you eat, especially if you have diabetes, for most people dietary cholesterol isn’t nearly the villain it’s been portrayed to be. Cholesterol in the bloodstream, specifically the bad LDL cholesterol, is what’s most important. And the biggest influence on blood cholesterol level is the mix of fats and carbohydrates in your diet—not the amount of cholesterol you eat from food.

Why does most of the Diet fails!

Author: Kumar, Vasanth (Sports Scientist – Performance Coach)

            Have you ever wondered why “dieting” Fails? If you have this question here is the answer that you have searched for all years long.

“Scientists say that human body were genetically designed to accumulate fat based on the days when we had to forage for food in the wild.  Ignoring that fact becomes hazardous to both our health and our waistlines. We have very few genes to protect us from overeating while with starvation protection, we have many and that is one of the causes for the fail.”

The reason diets backfire almost all the time is that people restrict too much. The number of calories consumed daily drops below the resting metabolic rate (RMR) while this basic amount of energy or calories is needed to run your metabolism per day. For an average person it is about 10 times your body weight in pounds (international standard). Remember Resting metabolic Rate is nothing but your daily basic need for your body to simply be alive (Just stay in bed without any energy expenditure).

If you eat lesser than the RMR (which the most diets mandate), your body will instantly perceive danger and alarms the systems that protects and defends your from starvation which furthers slows the metabolism. Therefore, your body goes for starvation mode and signals to eat. You start eating more than much-needed and you stop the diet that is a classic rebounding weight gain scenario. Just think of what happens when you skip breakfast, work through lunch, and finally return home in the evening: you eat everything in sight. Then you feel stuffed, sick, and guilty.

Strategies to Stop Overeating

Cut out the processed stuff and eat real, whole foods.

The single most important thing to lose weight and avoid overeating is to include as many real, whole, unprocessed foods in your diet as possible. Starting now, make the switch to these foods to lose weight: vegetables, fruits, whole grains, beans, nuts, seeds, olive oil, organic, range, or grass-fed animal products (poultry, lamb, beef, pork, eggs), and wild, smaller fish such as salmon.

Eat breakfast.

Skipping breakfast means you’re eventually starving, and throughout the day you eat much more food than needed to feel full.

Eat Peacefully.

We need to be in a relaxed state for the nervous system of our gut or digestive system to work properly. Eating while we are stressed out makes us fat, both because we don’t digest our food properly and because stress hormones slow metabolism and promote fat storage, especially of belly fat. We also tend to overeat when we eat quickly, because it takes the stomach 20 minutes to signal the brain that we are full.

Moderate or cut alcohol.

Besides getting rid of extra sugar calories, will help you tune in to your true appetite and prevent you from overeating.

Beware of trigger foods.

For some of us, that one little soda can set us on a downward spiral to overeating and all the negative health consequences that come with it. It isn’t just the processed, sugary foods and drinks that become triggers. But even healthy foods, if you have a tendency to binge on them, can quickly become unhealthy. A handful of almonds are perfectly healthy, but if you eat half the jar, they quickly become unhealthy.

Get enough sleep.

Get eight hours of quality, uninterrupted sleep every night. You’ll find that you’re less prone to cravings and you will normalize fat-regulating hormones. One study found even a partial night’s sleep deprivation contributes to insulin resistance, paving the way for obesity and type 2 diabetes.

Control stress levels.

Most of us fail to notice the effects of the chronic stresses we live with every day: demanding jobs, marital tension, lack of sleep, too much to do and too little time to do it. I am sure the list goes on for many. Chronic stress makes us overeat, not to mention overeating the wrong kinds of food, which ultimately leads to weight gain. Remember “Stressed” spelled in reverse is “Desserts”

Exercise the right way.

You can’t over-exercise your way out of a bad diet, but the right exercise can help you lose weight, maintain weight loss, and control your appetite so you don’t overeat. Ideally you should do a minimum of 30 minutes of cardio at least 3 days a week. More vigorous and sustained exercise is often needed to reverse severe obesity and diabesity. Run, bike, dance, play games, jump on a trampoline, or do whatever is fun for you.

Supplement if needed.

Obesity and diabetes are often paradoxically states of malnutrition. It has been said that diabetes is starvation in the midst of plenty. The sugar cannot get into the cells. Your metabolism is sluggish, and the cells do not communicate as a finely tuned team. Nutrients are an essential part of getting back in balance and correcting the core problem— insulin resistance.

Footwear with heels and their biomechanical impact on heel pain

Author: Kumar, Vasanth (Sports Scientist – Performance Coach)


Women loves high heels, but if they continue wearing them all time chances of significant foot pain and associated problems either can occur directly or exacerbated by wearing heels. (Morin, n.d.).

Any time person wears footwear that disturbs or realigns the natural counter of the foot they are bound to cause foot pain the experts says. While, if you add a bit of inches (high heels) in to this calculations then the pain can soon escalate to damage says Stuart Mogul expert in podiatry. Due to this, there exists the change in the body segmental alignment. For instance wearing high heels will restrict the natural movement of the foot and in addition to the restriction there is increased loading of weight on that area hence the person is not just crushing the toes, but adding exaggerated body weight on them says the Sports Scientist (Biomechanics) Vasanth Kumar from Chennai who is also a performance coach.

Consequences of wearing footwear with heel

                Researchers have found that people wearing high heels (2 Inches or more) have tighter calves. About 13% short on the calf muscle fibres on an average was found in the calf muscle scans among the people with frequent heel wearers in comparison with the people who avoided wearing heels. A study by Journal of Experimental Biology found that high heels led to stiffer calf (Achilles) tendons.

                A study by Professor Marco Narici, (Manchester Metropolitan University) that involved 11 volunteers from 80 group of women who wore 5cms (2 Inches) of heel for over a period of two years had issues and struggled while walking on flat foot (Bare Foot). An MRI Scan of these volunteers showed no significant difference in length of the calf muscles in comparison with the group of women who wore flat shoes. While, an Ultra Sound scan showed shorter calf among the women who wore heels. In addition, the women who wore heels were asked to lie on their front on the couch and the researchers noticed the angle of the heel were greater due to the shortened calf. Above all these, the tendons were much thicker and stiffer among the women wearing heels than those who wore flat footwear that causes discomfort while walking on flat feet since the tendon cannot stretch sufficiently.


                Sammy Margo, chartered physiotherapist from London says not to wear heels or flat shoes all the time but to wear variety of heel heights that can keep the muscle in right length (Anon., 2010). Secondly, the researchers and scientists have found out that performing some regular stretching activities can minimise the issue of calf muscle tightening.

Stretching Exercises

  1. Stand on tiptoes on a step, and using a handrail for balance to lower their heels as far as they can and hold the position for 10 – 15 seconds.
  2. Strengthening the Tibialis anterior (Shin Muscle) muscle can be of a help (Toe Raise) for a count of 8 – 10 Repetitions 2 -3 sets a day says the Sports Scientist.

Calf Stretch  Toe Raise (Strengthening)

                          Calf Stretch                                                Toe Raise Strengthening.


Select footwear with low heels – an inch and a half or lesser while a wider heel base can be of more help; a slightly thicker heel will spread the load more evenly. Narrow, stiletto-type heels provide little support and three inch or higher heels may shorten (Tighten) the Achilles tendon.

Softer insoles can reduce the impact on the knees.

Selecting right size footwear is more essential. Wearing shoes that allow your body to move naturally during walking will allow your feet, legs, hips and back to stretch.

Stretch your muscles as many times as possible during the day and while during rest.

Difference in Radiographs between High Heels and Normal Footwear


       Do not let your sense of style cripple your ability to stand or step pain-free. “Your feet are, quite literally, your base of support. If your feet aren’t happy, nothing above them will be,” says Dr. Nevins. “Take a closer look at your shoe selection and take small steps now to prevent big foot problems later.” (Nevins, 2015). In addition to all these the above exercises as a regular routine will keep the muscles in the right length and can be used as the preventive factor.
