Are you losing strength year on year? Time to check your muscle health
Understanding sarcopenia
The etymology of the term 'sarcopenia' stems from Greek words 'sarx,' meaning flesh, and 'penia,' meaning loss. It refers to progressive loss or reduction in skeletal muscle precipitated by ageing. We can lose 3–5% of muscle mass every decade from age 30, and after 60, the rate accelerates. The loss can affect anyone, especially those with less active lifestyles; it is not just athletes or seniors that this happens to.
Muscles are crucial for posture, movement, and overall functioning. Thus, loss of independence and quality of life can occur when your muscles start to get weaker. Sarcopenia, as with most other diseases, is often ignored in the initial phase. You might notice more fatigue, slowness in walking, or trouble lifting objects that were once easy to lift. There could be symptoms like atrophy of limb muscles, a slower gait, and even an increased risk of falling. Though some may attribute these signs as harmless, they signal an impairment that can get very debilitating when left unchecked. Sarcopenia also enhances the likelihood of hospitalisation, falling, fractures, and mortality. Despite sarcopenia's serious complications, it often goes undiagnosed and untreated.
Diagnosis and treatment of sarcopenia
Simple tests can identify sarcopenia. Physiotherapists, trained professionals, can use clinical tools like grip strength, walk speed, and sit-to-stand tests to detect early signs of muscle weakness. Overall health and muscle health are importantly indicated by grip strength.
Once diagnosed, there is no call for a miraculous cure. Instead, movement—purposeful, structured, and focused movement with a physiotherapist's guidance—is the best therapy. Prevention, treatment, and even the reversal of sarcopenia are up to physiotherapy. A physiotherapist does not merely write prescriptions; they design programmes tailored to each patient's age, ability, and underlying medical conditions.
Stability exercises might be appropriate for a person having difficulties with balance, whereas low-impact resistance exercises might be suitable for a person with knee arthritis. Resistance training is the most appropriate exercise for sarcopenia. Resistance training is all about building muscle strength, while aerobic exercises are appropriate for the heart. Light weights, resistance bands, or one's own body weight can be utilised for this. To prevent injury, physiotherapists should guide patients to perform these exercises gradually, safely, and effectively, thereby building strength.
Need in senior citizens
Resistance training and balance exercises are important for elderly citizens. To offer complete enhancement of physical function, physiotherapists also incorporate endurance and flexibility training. Fear— fear of falling, fear of hurt, or fear that their status will deteriorate—is one of the principal barriers to overcome for individuals with sarcopenia. Physiotherapists address this on a psychological as much as on a physical level. Physiotherapy restores strength and helps gain confidence by imparting effective techniques, correcting postures, and providing a secure exercise setting.
Take the case of Mr. X, for instance. Last year, the 68-year-old retired educator noticed that he was moving slowly, was more tired than normal, and could not easily get out of his chair. Initially, he attributed it to a natural part of ageing, but when he fell twice in the space of a month, nothing was the same again. He was investigated and diagnosed with sarcopenia after a trip to a physiotherapy clinic. He managed to regain his strength through the use of a tailored resistance training regimen at home, some dietary advice from a dietician, and regular balance exercises. Six months later, he is again taking morning walks and, more importantly, he feels good about his body.
Nourishment is as vital as physical therapy. Older people often don't get enough protein for muscle repair and growth. To ensure patients receive the amount of protein they need (usually 1–1.2 grams per kilogram body weight) as well as essential nutrients such as vitamin D and calcium, physiotherapists tend to collaborate with dietitians.
Early diagnosis and treatment, vital
Early treatment is crucial. The longer muscle loss goes untreated, the harder it becomes to reverse. Physiotherapists advise that all people over 50 should undergo routine screening, especially if they've not been active, recently been unwell, or have seen a reduction in their capabilities. In its initial stages, early physiotherapy can both halt sarcopenia and reverse it. Home visit physiotherapy services, community fall prevention programmes, and group exercise classes are all successful models being utilised in India and abroad.
So, if you think that you have sarcopenia, what should you do? Begin by paying attention to your own body. Are you getting weaker or more tired than normal? If the answer is yes, seek help.

Greece battles wildfires across country, evacuates villages
A destroyed car is seen on scorched land as a wildfire burns, in the village of Thymari, near Athens, Greece, June 26, 2025. REUTERS/Stelios Misinas DROSOPIGI, Greece (Reuters) -Firefighters were battling wildfires near Athens and across Greece on Saturday as the Mediterranean country sweltered under the third heatwave of the summer, with some villages and settlements being evacuated. Explosions could be heard as huge clouds of smoke covered Drosopigi village 25 km north of Athens, where factories with flammable material are located. Helicopters dropped water and 65 firefighters battled the flames, assisted by 26 vehicles and two aircraft. Two houses caught fire, according to state ERT television, while residents of nearby village Krioneri were instructed by authorities to leave towards Athens. Temperatures in Greece were forecast to reach up to 44 degrees Celsius on Saturday, the Greek weather service said. On the island of Evia, 115 firefighters and 24 vehicles were deployed to put out fires, assisted by six aircraft and seven helicopters, but strong winds were hampering their efforts. Residents of the island's Triada area were told to be ready in case they needed to leave. The fire on Evia is the latest in a series of bushfires stoked by strong winds and dry conditions this month. On the island of Kythera, authorities evacuated the villages of Aroniadika, Pitsinades and Aryoi. In the area of Messinia, west of Athens, residents of the Kryoneri and Sellas villages were also told to leave. These sites were on a list of Greek regions on high alert for wildfires due to record-breaking temperatures and strong winds due on Saturday. Tourism is a key earner in Greece, and the fires have hit since the start of the peak summer holiday season early in July. Greece and other Mediterranean countries are in an area dubbed "a wildfire hotspot" by scientists, with blazes common during hot and dry summers. These have become more destructive in recent years due to a fast-changing climate, prompting calls for a new approach.

Is Rhodes' Old Town a tourist trap or medieval paradise?
So when The Ixian Grand & All Suites invited me to explore this beautiful part of the world, I was thrilled. Before visiting Old Town I had spent 3 amazing days in Rhodes. The food, hotel staff, suite and pool had combined to create the perfect Dodecanese marriage, but I still had a hunger for more. Well two hungers to be precise, more food and also culture. Is Greece still the place to go for the best holiday? Here's my salty experience — Matt Evans (@MTEvans1995) July 11, 2025 First impressions of the Old Town of Rhodes: The Old Town of Rhodes has been declared a World Heritage Site by UNESCO and it is visited by thousands of travellers every year. Palace of the Grand Master is an awe-inspiring fortress that looms ominously over Old Town. Originally built by the Knights Hospitaller in the 14th century, it is often cited by Greek tourist boards as the definitive must-visit spot. The intricately designed back alleys and buildings are beautifully preserved and a great way to experience what life was like in the past. First impressions for me though? Well, I'd wager some folks would get bored after 15 min and others would be content to spend an entire day there. But which category did I fall under? I went to Rhodes looking for love but ended up with a goose My Old Town experience: Food was on my mind. And lots of it. Despite being thoroughly treated by The Ixian Grand & All Suites over the prior few days, I had a hunger for more. After roaming around the streets for an hour or so, I landed on the first restaurant - yes, first. A quaint tiny little Greek place tucked behind one of the cobbled streets. It was early in the day, so I fancied fish and white wine. After roaming around the streets for an hour or so, I landed on the first restaurant (Image: Newsquest) I scoured the menu and it seemed the right place for me. Plenty of different fish courses, white wine and accommodating staff who gave me a complimentary shot of Souma, then another, then another. Several locals had urged me to try the Dodecanese alternative of ouzo or raki over the previous two days. But 'proper' souma. I'll be blunt, it is essentially white spirit, as I was essentially staring at two menus by this point. A cunning ploy by the staff to be fair, as I proceeded to order the mussels and octopus, the most expensive items on the menu, but equally delicious. This was the prelude to my final Rhodes lesson. But we'll come on to that. Old Town is a bouncing, bustling, little spot brimming with, dare I say it, tourists. But in all fairness, it seems to be designed that way. The bars for example. One place has a flag for every country in the world and will set it on your table if you tell them where you're from. Genius marketing, playing on an idiot's love of country. So after I finished a pint opposite my Welsh flag, I headed to my second and final restaurant of the day for something, heavier. It was a steakhouse slap-bang in the middle of Old Town. Unlike bars and pubs, I have always held the belief there should be a different playbook for restaurants. Keep to yourself/table. This restaurant was bouncing with people from all walks of life, friends, families and a weirdo sitting alone in the middle, me. I couldn't have been in a better spot to people-watch. Just me, my T-bone steak and a glass of wine. What more could you ask for? (Image: Newsquest) But before long, Old Town was starting to get, well, old. You only need to spend a day there to sample all of its delights, or even less, personally. The downsides of Old Town: Sadly, it was at this point that the experience started to get sullied. I looked at the chuffing expensive bill and noticed I'd been charged for a couple of items I never had, so I called over the waiter and got them removed. Now I was slightly miffed. Despite that, my next recommendation awaited - the nearby village of Faliraki, as Lindos was on the complete opposite end of the island. For that, I needed a taxi. Sigh. After a 20-minute wait at a taxi rank just outside the city walls, two strangers and I were told to get in a minicab. Faliraki is 23 minutes away from Old Town, according to Google. When we got in, we were told "50 Euro for taxi", this later translated to "Everyone sharing this taxi pays 50 Euros each." 150 Euro, for a 23-minute journey. I'm not saying that every cab driver would try this, but if you're going to get a taxi, agree on a price beforehand, get a bus instead, or risk your mortgage. Rhodes, or rather, Old Town, was an incredible experience and one that I will never forget for both good and bad reasons. My hotel, The Ixian Grand & All Suites, was sensational, as were my trips out to places such as Old Town. It is, without question, stunning. An area of the world you will never likely stumble across again, with a fascinating history to back it up. But on the downside, it does have its problems. Old Town in the summer months is jam-packed with tourists which then births another problem, rip-offs. Amidst the many, many souvenir shops, bars and restaurants, you need to have your wits about you. But if you can manage that, I have no doubt the experience will be unforgettable, for the right reasons.
