Some like them big, some like them small, but either way, the size of your calves can tell a lot about your health.

MEN take pride in having them big, but women want them slender.

It’s a skeletal muscle group that’s difficult to bulk or trim, even though it’s one of the most used in daily tasks.

If you’re unsure which muscles these are, I’m referring to the calves.

Genetics and anatomical structure play a significant role in how the muscle is shaped and how large it can grow.

The calves comprise of two main muscles: the outer gastrocnemius (known as the calf belly with two “heads”, i.e. medial head and lateral head), and the underlying soleus, which is the smaller of the two.

Together, they are responsible for bending the ankle joint upwards (dorsiflexion) and straightening it to point your toes (plantarflexion).

These two muscles taper and merge at the base of the calf muscle, and attach to the heel bone (calcaneus) via the Achilles tendon.

During walking, running or jumping, the calf muscles pull the heel up to allow the body to propel forward.

There is also another small muscle that runs beneath the gastrocnemius and soleus, called the plantaris.

It has a short belly and a long, thin tendon that connects to the Achilles tendon.

Functionwise, the plantaris muscle assists the gastrocnemius, but not significantly.

In fact, in 10% of the population, this muscle is completely absent.

Bigger or smaller?

Basically, the size of your calf muscles is determined by how far your heel bone (calcaneus) projects backwards, i.e. its length.

The longer this bone is, the smaller your calves.

In one 2011 study, researchers studied individuals of similar height, weight, lower limb length and foot length, and discovered that the ones with shorter calcanei had bigger calves.

Meanwhile, those with longer calcanei had more slender calves.

They also looked at the muscle recruitment patterns and found that people with shorter heels and big calves were using their medial gastrocnemius muscle more than the lateral gastrocnemius muscle while walking.

In contrast, those with longer calcanei had more evenly distributed calf contractions.

People with skinny ankles (small girth) will not be able to build bulk in their calves, although they have a lot more agility than their counterparts with thicker ankles.

Sprinters generally have bigger calves due to the extraordinary amounts of explosive power required to sprint short distances.

Long distance runners, on the other hand, tend to have slender, toned calf and leg muscles.

In fact, the calves in animals that move fast are practically non-existent.

Sausage legs

There is no ideal or normal proportion for the calves and ankle – it depends on what is beautiful to the eye.

Aesthetically, we are all wired to desire ankles that are smaller than the calves.

However, there is a condition where the ankle is just as thick or slighter thinner than the calf, making the lower leg look like a cylinder.

This “cankle” – a combination of the words “calf” and “ankle” – is not a medical term, but a word made popular in 2001 when Jason Alexander’s character in the movie Shallow Hal used it to criticise an overweight woman’s lower leg, saying, “It’s like the calf merged with the foot, cut out the middleman.”

When you have cankles, you’ll find it hard to differentiate the calf from the ankle. Some people call this “sausage legs”.

Women are more prone to this as it seems to run in the female line, with mothers, sisters and other female relatives tending to have the same lower leg shape.

Unfortunately, there is just so much you can do to alter it through natural means besides losing the fat that is covering the ankle.

Sometimes, however, these cankles are due to medical conditions like excessive water retention, kidney disease, bad sprains and surgery.

The calves are prone to tightening and cramping, especially after a workout, so be sure to stretch them out.

If your ankles remain swollen over a long period, do seek medical advice as it could be the sign of something sinister, like heart failure.

Managing those muscles

If you’re genetically predisposed to having big calves and don’t want to bulk further, the best you can do is to scale back on high intensity, skipping, plyometric and heavy weight-bearing exercises as they contribute to hypertrophy or muscle growth.

Also, don’t walk, hike or run up on an incline (e.g. hills or uneven surfaces) as these activities force your calf muscles to work harder.

They will definitely get stronger, but could also get bigger.

Instead, stick to running on flat surfaces.

To build your calf muscles, there are only two types of effective, yet simple exercises: heel or calf raises with knees straight (for the gastrocnemius) and with knees bent (for the soleus).

Start with one set of 12-15 repetitions with your feet parallel first.

Then turn your feet out (toes pointed out or away from the body) for the next set.

For the last set, turn your feet in. This forces your muscles to work from different angles.

To target the soleus muscle, repeat the entire sequence seated, perhaps with a light dumbbell on your thighs.

Do three sets, but only with your feet parallel.

You may not see noticeable bulk, but you’ll see some tone and more definition.

Stretch and soak

The calves are prone to tightening and cramping, especially after a workout, so be sure to stretch them afterwards.

The simplest way to do this is to stand at the edge of a step and place the balls of your feet on it.

Keep your legs straight (use the wall or railing for support) and reach your heels to the floor until you feel the stretch in your calves and Achilles tendon. This stretches your gastrocnemius muscles.

To stretch your soleus, do this with one knee bent, then repeat on the other side.

In addition, you can try soaking your lower leg in warm, salt water for 15 to 20 minutes before patting dry with a towel.

Then, apply some oil or lotion to self-massage the calves using stroking motions towards your hip.

Depending on your preference, you can use your fingers, palms, heel of your hand or knuckles.

Strong pressure reduces tension and pain in your muscles, while using a light pressure is more relaxing, especially before you retire for the night.

Benefits in all sizes

Fret not if your calves are big because there are some health benefits associated with it, according to a 2008 study published in the Stroke journal.

Apparently, regardless of age, gender, body mass index (BMI) and other vascular risk factors, those with bigger calves have fewer fatty deposits known as plaques built up in their arteries, thus lowering their risk for stenosis, carotid artery disease and strokes.

Researchers suspect this may be because big calves give the body another place to store fat that could cause problems when they’re floating in the bloodstream.

At the same time, people with bulky calves could also be more prone to non-alcoholic fatty liver disease as the calves act as a proxy for fat deposits.

In a 2013 study in the Journal of Physical Therapy Science, researchers concluded that the smaller a person’s calves are, the higher their resting heart rates might be.

In general, high resting heart rates, or anything above 100 beats per minute, have been linked to an increased risk of death, regardless of physical fitness.

A normal resting heart rate for adults ranges from 60 to 100 beats per minute.

A lower heart rate at rest implies more efficient heart function and better cardiovascular fitness.

So, all is fair whether you have big calves or small.

On that note, here’s to a brighter 2021!

Inject awareness’ of how Covid-19 vaccine works

Experts: Govt should launch awareness campaign to be transparent on safety

To allay concerns brought about by anti-vaxxers, health experts suggest that the government come up with a campaign to educate Malaysians on the safety of Covid-19 vaccines. The National Council on Islamic Affairs has given the go ahead for inoculation. 

Health experts are urging the government to come up with a vaccination awareness campaign now to alleviate public fears and concerns over the Covid-19 vaccine with the arrival of the first batch by February.

Universiti Malaya expert virologist Prof Dr Sazaly Abu Bakar said through a campaign, the government should explain how the vaccine actually works.

“What we do not want is the ripple effect after this in which not only the Covid-19 vaccine is affected but also vaccines for other infectious diseases which we have been using for eons.

“Anti-vaxxers are trying to sow distrust on vaccines. It is not just about the Covid-19 vaccine but their aim will be affecting all the other childhood disease vaccinations which is not good,” he said when contacted yesterday.

He explained that a vaccine can only enter the country after the National Pharmaceutical Regulatory Agency ( NPRA) approves it although the government has made allocations to purchase the vaccine.

“The vaccine cannot be brought in and distributed to the people until the NPRA has verified that it is safe to use.

“The rakyat should not be concerned about all these other issues that are non-scientific, non-science-based and non-data-based. What the rakyat should know is that there are different platforms for different vaccines.

“This is good because that means the government is giving us the option of choosing which vaccine we want to take eventually as there are people who are allergic to certain components of a vaccine. Maybe when one vaccine is not suitable, another one is suitable,” he said.

So far, the Health Ministry had implemented a nationwide survey to gauge the interest of Malaysians in getting the Covid-19 vaccine.

It was also announced that Prime Minister Tan Sri Muhyiddin Yassin would be among the first to take the vaccination.

Universiti Putra Malaysia medical epidemiologist Assoc Prof Dr Malina Osman said proper policy and regulation is needed to handle vaccine skeptics and anti-vaxxers.

“Once we have bold scientific evidence on the effectiveness and safety of the vaccine, the gazettement under the law should be carried out to disallow those who have no authority to talk against the vaccine, and there should also be provision on an appropriate punishment for those who talk ‘nonsense’ about the vaccine,” she said.

“In the Muslim community, the issue on whether the vaccine is halal or not have been raised by those who reject the vaccine. This group provides isolated evidence against the decree by recognised religious scholars towards acceptance of the treatment from the Islamic point of view,” she said.

Prof Dr Moy Foong Ming, from Universiti Malaya Faculty of Medicine’s Department of Social and Preventive Medicine, concurred that a vaccination campaign should be set up while also being transparent on the safety, side effects and efficacy of the vaccine.

“The government should be transparent on the safety, side effects and efficacy of the vaccine. The total uptake and among subgroups of vaccination should also be presented to the public.

“The media should publish equally on information of the efficacy and safety as well as the side effects of the vaccine.

“Clear explanation of why the side effects happen, who are the high-risk groups and what are the chances of a side effect that will happen should be presented to alleviate people’s fears,” she said, adding that relevant government agencies should address religious concerns.

Dr Moy added that highlighting the fact that “all vaccines and medicines have some side effects, including Covid-19 vaccine” should be emphasised to the public.

Time to grow own greens

 

 Effortless Effort—The Eat-All Greens Garden


https://youtu.be/9a-dUO7Qn58

 

A participant trying her hand at composting with a pipe during the chemical-free urban farming workshop by CAP.

THE movement control order (MCO) saw people stocking up on essentials like canned food, rice, noodles and seasoning, but they overlooked the need for greens in their diet.

Perhaps, marketing and buying vegetables would not have been a matter of top priority during such trying times but many failed to realise that one can grow these greens in the tiniest space available.

To teach the public on the perks of having their own greens to cook as well as ways to make these plants thrive under any living condition, Consumers Association of Penang (CAP) has come to the rescue by holding its monthly chemical-free urban farming workshop.

CAP education officer N.V. Subbarow shared how many do not realise about the chemicals that are used to keep vegetables fresh for days.

“If you can plant and grow your own vegetables it would be great.

“Now with this pandemic, many are not consuming vegetables as it is considered easier to just eat canned or take-away food.

“There are many preservatives in those meals and in the long run it can cause health issues.

“If one can plant and grow greens in their house, it would not only be good for their health but the environment as well.

“Here we are teaching people the correct way to plant vegetables and how to produce compost to ensure a great yield as well, ” he said at one of the workshops at the CAP premises in Jalan Masjid Negeri, Penang, recently.

Subbarow said the workshop aimed to teach people how to plant vegetables like chilli, okra and other greens.

“We have tested shop-bought vegetables and many times they contain chemicals to keep them fresh.

“Here you know what goes into growing your vegetables at home.

“We have ways in which people can plant their vegetables even if they are living in an apartment.

“These are vegetables that are consumed daily.

“You only need the right soil.

“They can be planted in pre-used pots or containers, ” he said.

Subbarow said the participants were taught to not only plant vegetables, but also on how to keep pests away from plants organically by using other plants to ward them off as well as homemade growth enhancers for plants using fish and brown sugar.

“It can be a whole family hobby, planting and harvesting their vegetables.

“I encourage families to plant now as they can start harvesting in weeks or a few months depending on what they plant.

“This is one way to save money as well, because by cooking two vegetable dishes from your garden, you have covered one meal for the day, ” he said.

Subbarow then taught the participants how to make compost, one being collecting organic waste and making compost in a container.

“Then there is the seven pot system where organic waste is placed in a pot a day with pots marked for each day of the week.

“This helps keep track of your compost and then you can plant something in each pot.

“The third way is where a pipe is placed in the pot with 5cm of the pipe buried in the soil.

“Organic waste is placed in the pipe and the pipe is closed to avoid water mixing with the compost.

“The roots of the plant in the pot will absorb the nutrients from the compost, ” he said.

CAP education officer Saraswathi Devi Odian also taught participants to layer soil in a pot.

“People do not realise you have to mix the soil.

“You need half the pot to be filled with garden soil, the other half has to be equal parts of sand, red soil and compost, ” she said.

Friends Rachel Jasmine Richard and M. Deenadayalani, both 27, were happy to attend the workshop to learn about planting vegetables.

Rachel said she had planted curry leaves and pandan, but now realised that she did not use the right soil.

“I only used garden soil which is not good enough.

“I now want to plant chillies and will do it the right way.

“I always wondered if I could use the peels from vegetables and fruits, now I know I can compost it, ” said the customer service representative.

Deenadayalani, whose mother loves to plant vegetables, said they have quite a number of greens in their garden.

“I would like to plant tomatoes next, ” she said.
