How can I build muscle as I age? Experts share strength training and diet tips for midlife gains
Maintaining and building new muscle does become harder as you get older. Even if you work out regularly, you might struggle with, say, opening a pickle jar or lifting a suitcase more than you did when you were younger.
With age, your muscles become less responsive to the things that built them up in the past – namely strength training in combination with a protein-rich diet, said Bradley Schoenfeld, a professor of exercise science at Lehman College in New York.
At the same time, your sex hormones – primarily testosterone for men and oestrogen for women – decline as you get older, which also hampers your body's ability to build new muscle. And chronic inflammation may also increase with age, which can make it harder to repair and build new muscle, since your immune system has to work harder to keep you healthy.
But your biology isn't entirely your destiny, Dr Schoenfeld said, and strength training can go a long way toward slowing or counteracting these changes. While some muscle loss is inevitable, the rate at which it declines is heavily influenced by lifestyle. Resistance training is like saving for retirement, he said. The earlier you start, the better off you'll be down the road. Regardless of when you begin, though, it is possible to build new muscle at any age.
YOU CAN SLOW DOWN THE CLOCK
Several studies do suggest that adults lose 3 to 8 per cent of their lean muscle mass per decade starting at around age 30, and even more after age 50. But this decline is as much a result of shifting exercis e habits as physiological changes, experts said. The less you work your muscles, the less work they are able to do and the faster they atrophy.
It can lead to a dangerous downward cycle, said Christopher Miller, a strength and conditioning coach with Mount Sinai's Department of Rehabilitation and Human Performance. People find working out to be harder, so they do less, and then they find it even harder to work out.
On the flip side, people who strength train continuously into middle and older age tend to hold onto more muscle mass. 'Their trajectory is different,' said Anne Friedlander, an exercise physiologist and assistant director of Stanford University's Lifestyle Medicine Program.
But even if you've been inactive until now, strength training can stall or reverse muscle loss.
Whether you're picking up weights for the first time or looking to improve on your current routine, here's how to maximise your muscle as you age.
LIFT BEYOND YOUR COMFORT ZONE
It doesn't really matter if you lift light or heavy weights, Dr Schoenfeld said. The important thing is that you regularly push yourself during your strength training workouts. 'The last several reps need to be very challenging,' he said – what trainers often call lifting close to failure.
Consistency also becomes more essential as you age, since the older you get, the more your muscles need to be continually challenged to maintain their mass, or build new mass, Miller said.
Older bodies also take longer to rebuild strength and power once they've become deconditioned, so the less consistently you stress your muscles, the steeper a decline you'll experience.
Experts recommend doing at least two, 20- to 30-minute strength training sessions per week.
EAT PROTEIN – AND CARBOHYDRATES
Because your muscles become less responsive to protein over time, you may need to eat more of it to maintain or build muscle mass as you age, and may benefit from tweaking your diet so a higher percentage of your calories come from protein.
But don't skimp on carbohydrates either, Dr Friedlander said, since you'll need them for energy to push yourself during strength training. Most of the carbs you eat should be complex carbs (think whole grains) for long-lasting fuel. Foods with simple carbs (think fruit) can help quickly boost your energy immediately before, during or after a workout.
Dr Friedlander also recommended that older adults add a creatine supplement to their diet to help spur muscle growth.
DON'T RUSH YOUR RECOVERY
As you get older, it's important to prioritise recovery time between bouts of strenuous exercise. You can still be active on recovery days, Dr Friedlander said, but be careful not to overwork the muscle groups you most recently trained, since this could backfire: Not only could it impair muscle growth, but it could also increase your chances of injury. A brisk walk or a gentle bike ride can both be good options for an active recovery day.
Along with prioritising recovery, getting enough sleep and managing your stress level can help to reduce chronic inflammation, which can improve your ability to build muscle.
Finally, be patient, Miller said. It might take longer than it did in the past for you to see or feel new muscle growth, but if you consistently work your muscles hard, it will happen. Your older self will thank you.

Manhattan shooting renews focus on CTE, concussion risks in amateur sports
NEW YORK :A deadly Manhattan office shooting by former high school football player Shane Tamura has renewed attention on how head injuries are managed in amateur football. Tamura, 27, fatally shot four people before killing himself, leaving a note blaming chronic traumatic encephalopathy, or CTE, and the NFL for his actions. National Football League headquarters are in the Park Avenue building where the shooting occurred. Tamura, who played at a Los Angeles charter school, had not been diagnosed with CTE, which can only be confirmed post-mortem. New York City's Office of Chief Medical Examiner said it will conduct a neuropathological assessment during his autopsy, with results expected in a few weeks. But persistent questions about the effectiveness of strategies for tracking and managing repeated head trauma in young athletes are again facing scrutiny. Karissa Niehoff, CEO of the National Federation of State High School Associations that oversees high school football in the U.S., said her organization "does not know how many serious concussions are reported each year.' "Concussions occur among all age groups and in many activities, but are often not reported. Those at the scholastic level might involve reporting to a school nurse, athletic trainer, or coach," Niehoff said. Concussions are sometimes called "snowflake injuries" to reflect their unique and unpredictable nature. Monitoring student-athletes is difficult for organizations like the NFHS, since state associations have no oversight once students graduate. A 2023 Boston University CTE Center study that examined the brains of 152 youth, high school, and college athletes, most of them football players, who had died under age 30, found 41 per cent showed signs of CTE. Suicide was the most common cause of death, but not all athletes with symptoms had CTE, the study found. There was no statistically significant difference in clinical symptoms between those with the brain disorder and those without. "They only played high school or college level and still had developed the changes of CTE," said Boston Center Director Ann McKee. "It's not well understood that kids playing amateur level sports are at risk. This isn't a disease only of pro athletes," she said, calling it a public health issue. "There's an urgent need to address it at the amateur level." According to NFHS data, about 30 per cent of athletes with concussions may have symptoms lasting over four weeks. The NFHS has not labelled brain injuries in amateur sports a public health concern, in contrast to the Boston CTE Center. Protocols are in place to protect athletes suspected of incurring head injuries, requiring immediate removal from play at all levels. However, there are major differences between professional and amateur protocols. The NFL uses a five-step return-to-play process, including evaluation by an independent neurological consultant. Most high schools cannot afford independent neurologists, relying on athletic trainers, who may lack specialized concussion training, to assess injured players. Technology also plays a role in player safety. Professional teams use helmet impact sensors and analytics to monitor hits. High school programs rarely have access to such technology and rely on visual observation and self-reporting by athletes, who may feel pressure to keep playing. "We know that many changes have been made in sports to address potential head injuries," Niehoff said. "We also know that as we learned more about concussions, the number of reported concussions increased." AGGRESSION NOT A UNIVERSAL SYMPTOM Some individuals with CTE show increased aggression, but violence is not a universal symptom. Several ex-NFL players, including Jovan Belcher, Irv Cross, Conrad Dobler, Chris Henry, Vincent Jackson, Terry Long, Junior Seau, Demaryius Thomas and Frank Wycheck, were found to have CTE after their deaths. Some faced behavioral or mental health challenges such as dementia and depression following distinguished careers in the violent sport. Long, Seau, and Belcher died by suicide. Belcher fatally shot his girlfriend before taking his own life. Former New England Patriots tight end Aaron Hernandez was convicted of murder and died by suicide in prison at age 27. A posthumous examination revealed severe CTE. "Aggressive behaviour can be part of the syndrome, but it isn't universal and we don't know why some patients develop it and others don't," said Dr. Brent Masel, executive clinical professor of neurology at the University of Texas. "We can't explain where the problem lies in the brain. We're miles away from trying to figure that out," he said. "Just like with Alzheimer's disease, some become aggressive and some don't. Why that happens and whom it happens to, we don't know.' Progress in prevention and treatment has been slow. "We really haven't moved the needle much relative to the prevention of CTE... except we're a little better in treating the symptoms," said Masel. "Not every athlete with a history of contact sports who develops psychiatric issues is going to go on to develop this problem," he said. "The last thing you want is everybody in a panic that their child is going to end up doing something like that," Masel said. "So the most important thing is to reassure the public that the chances of their child ending up doing what Tamura did are slim."

I'm lactose-intolerant – do I really need to avoid all dairy or are some products safe to eat?
Many people have lactose intolerance. In the United States, for instance, there are some 30 to 50 million people. This means their bodies can't adequately break down lactose, the sugar present in milk. The result can be uncomfortable gas, bloating, nausea, diarrhoea and abdominal pain, symptoms that typically occur within about 30 to 60 minutes of eating a lactose-rich food, said Beth Ferrell Jenks, a dietitian and assistant professor of nutrition at the University of North Carolina at Chapel Hill. The good news: While individual tolerances to dairy foods can vary, certain lower-lactose dairy products, like hard cheeses and yogurts, can help keep lactose intolerance symptoms at bay. HOW TO EAT WITH LACTOSE INTOLERANCE Trouble with lactose intolerance tends to begin in adulthood, when our bodies gradually makes less lactase, an enzyme that breaks down lactose. Some people might not notice this change in their digestion, said Dr Suneeta Krishnareddy, a gastroenterologist at Columbia University Irving Medical Center in New York City. But others may have symptoms so severe that they experience nausea and vomiting after eating certain foods, said Dr Nitin K. Ahuja, a gastroenterologist at Penn Medicine in Philadelphia. Understanding your triggers involves some trial and error. You might start by eliminating all dairy from your diet, and then gradually reintroduce small amounts of certain foods and drinks containing lactose to see how you feel afterward. Here are the dairy products most, and least, likely to exacerbate your symptoms. THE WORST OFFENDERS 1. Dairy milk: Skim, 1 per cent, 2 per cent and whole milk all contain between 12 and 12.5 grams of lactose per cup. That's around the maximum amount of lactose people with an intolerance can consume per day without having symptoms, said Ella Haddad, a dietitian and professor emeritus of nutrition at Loma Linda University in California. So try to limit yourself to one glass of milk per day, or less if you're consuming other types of dairy. 2. Unaged (or fresh) cheese: Cheese generally contains less lactose than milk, but some varieties have more than others. Cheeses that haven't been aged – meaning they haven't been left to ripen for weeks, months or years – typically contain more lactose than aged cheeses, Jenks said. This is because during the ageing process, bacteria break lactose down, converting it into lactic acid. Unaged cheeses tend to be soft and moist and often come in a tub. A half-cup serving of cottage cheese with 2 per cent milk fat contains about four grams of lactose. Two tablespoons of fat-free cream cheese has nearly two grams. While unaged cheeses are probably more tolerable than dairy milk, Jenks recommended limiting them when you have the choice. 3. Ice cream: Many ice creams, which are mainly made from milk and cream, are rich in lactose and therefore should be limited. But some versions contain more lactose than others. If an ice cream contains more milk than cream (you can tell by checking if milk is listed before cream on the ingredients list), it is probably rich in lactose and therefore harder to digest, Dr Haddad said. This is because milk contains more lactose than cream. OKAY IN MODERATION 1. Hard cheese: Varieties like Parmesan, cheddar and Swiss have been aged and therefore contain very little lactose and are often easier to digest than softer, unaged varieties, Dr Krishnareddy said. Harder cheeses tend to taste sharper and include an outer rind. A one-and-a-half-ounce serving of Parmesan or cheddar, for instance, contains less than one-tenth of a gram of lactose. 2. Other fermented dairy products: Fermented dairy foods like yoghurt, kefir and sour cream contain bacteria that help break down lactose, Dr Krishnareddy said. This lessens the load on your small intestine, making those foods easier to digest. 3. Butter: This kitchen staple is made from milk, cream or both by separating the fat from the rest of the liquid, leaving most of the lactose behind, Dr Haddad said. One pat of butter and one tablespoon of cream each contain about half a gram of lactose or less. WHAT ELSE CAN HELP Many supermarkets carry lactose-free dairy products like milk, cheese, yoghurt and ice cream. They are regular dairy products made from milk but with the lactase enzyme mixed in. This makes them more tolerable if you're lactose-intolerant, Jenks said. Dairy-free products like milk made from almonds, soya or oats; cheese made from nuts; and ice cream made from soya or coconuts are also lactose-free. Over-the-counter lactase enzyme supplements, which can be swallowed or chewed, can help reduce your indigestion symptoms when taken with a meal. They contain the lactase enzyme so your body doesn't have to make it itself, Dr Krishnareddy said. While many people can tell if they're lactose-intolerant on their own, Dr Ahuja said that it's usually a good idea to see a doctor for a proper diagnosis. Other conditions, like food allergies or inflammatory bowel disease, can cause similar symptoms.
