It’s time to add to your list of reasons to work out: Getting active could help prevent risk of death from the flu and pneumonia, according to new research.

Meeting the physical activity guidelines for aerobic and muscle-strengthening activity reduces risk of dying from influenza and pneumonia by 48%, according to a study published Tuesday in the British Journal of Sports Medicine.

Adults should get at least 150 minutes of moderate aerobic physical activity and two or more days of moderate muscle strengthening activities a week, according to the Physical Activity Guidelines for Americans issued by the US Department of Health and Human Services.

The study relied on the survey data of more than 570,000 people from the US National Health Interview Survey between 1998 and 2018. People were asked about their physical activity habits, and they were categorized into groups based on how well they met the recommended amount of exercise, according to the study.

On average, the respondents were monitored for nine years after the initial survey. There were 1,516 deaths from the flu or pneumonia in that time.

Meeting both recommendations for aerobic and muscle-strengthening activity cut the risk associated with flu or pneumonia death nearly in half, but meeting just the aerobic activity target was associated with a 36% lower risk, according to the study.

Both influenza and pneumonia are among leading causes of death in the United States and around the world, so the results are significant, said lead study author Dr. Bryant Webber, an epidemiologist in the US Centers for Disease Control and Prevention’s Division of Nutrition, Physical Activity, and Obesity.

“Readers may appreciate the importance of influenza and pneumococcal vaccination. This study might encourage them that physical activity may be another powerful tool for protecting themselves against influenza and pneumonia death,” he said.

The results make sense given existing knowledge, and the benefits may extend to other conditions, said Dr. Robert Sallis, director of the sports medicine fellowship at Kaiser Permanente Fontana Medical Center, and clinical professor of family medicine at Kaiser Permanente Bernard J. Tyson School of Medicine in California. He was not involved in the study.

“This study is also consistent with the various studies showing that regular exercise dramatically lowered the risk of COVID-19 related death in similar fashion,” Sallis said in an email.

But even if you can’t reach the recommended amount, some activity can still provide more protection than none, according to the study.

“We also found that any level of aerobic physical activity, even at amounts below the recommended level, lowered the risk of influenza and pneumonia death, as compared to doing no aerobic activity,” Webber said.

Getting 10 to 149 minutes a week of aerobic physical activity was associated with a 21% decreased risk of flu and pneumonia death, the study showed.

“Our overarching advice for everyone — regardless of age or perceived physical fitness level — is to ‘move more and sit less,’” Webber said in an email. “Readers who do not get any physical activity should be encouraged that doing any is better than none.”

That being said, no additional benefit was seen for people who got more than 600 minutes a week of aerobic activity, the study showed.

And in the case of muscle strengthening, there is such a thing as too much, the study showed.

Meeting the target of two or more sessions lowered the mortality risk significantly, but getting seven or more sessions was associated with a 41% increased risk of death by flu or pneumonia, the study showed.

However, this was an observational study, the researchers noted, which means that the study can’t make claims about what causes or prevents the deaths — just what factors were associated with a level of risk.

The increased risk could be related to a range of factors, including the cardiovascular impacts of frequent muscle-strengthening activity or inaccurate responses to the survey, the study said.

Even though there are limitations in the design, researchers often rely on these studies when it is impossible to randomize people into different lifestyles, Sallis said.

Aerobic activity — or cardio, as it’s often called — doesn’t have to mean getting yourself to the gym regularly, the study said. This type of movement is anything that gets your heart rate and sweat glands going, including speed walking, swimming, biking, running or stair climbing.

Exercises such as lifting weights, squats, lunges or even heavy gardening can count as your muscle-strengthening activity, the study added.

A megastudy published in December 2021 showed that the best exercise programs include planning when you work out, getting reminders, offering incentives and discouraging missing more than one planned workout in a row.

“If people are hoping to boost their physical activity or change their health behaviors, there are very low-cost behavioral insights that can be built into programs to help them achieve greater success,” said that study’s lead author Katy Milkman, the James G. Dinan Professor at the Wharton School of the University of Pennsylvania and author of “How to Change: The Science of Getting From Where You Are to Where You Want to Be.”

You can start small, said Dana Santas, a CNN fitness contributor and mind-body coach for professional athletes, in a 2022 CNN article.

“Fitting in ten minutes of exercise every day is so much easier than people think. Consider how fast ten minutes goes by when you’re mindlessly scrolling social media or watching your favorite TV show,” Santas said in an email. “It’s not a big time investment, but it can deliver big health benefits.”

Why jump training is ‘the most effective form of longevity training for women’ – and how to do it right

Why jump training is ‘the most effective form of longevity training for women’ – and how to do it right

As you age, you might think low-impact exercise is the safest route for long-term health. But according to leading physiologist Dr Stacy Sims, this mindset could be holding women back. In fact, incorporating impact-based training – specifically, jump training – could be the key to building strength, resilience, and longevity well into later life.

‘If you’re looking at what you want to do when you’re 80 or 90, you want to be independently living, you want to have good proprioception, balance, you want to have good bones, and you want to be strong,’ says Dr Sims. ‘This is where you should look at ten minutes, three times a week of jump training. We have to turn our brains away from everything that’s been predicated before to this point.’

Her advice comes on neuroscientist Andrew Huberman’s podcast, Huberman Lab, in which he says: ‘One of the most common questions I get is what is the most efficient way for a woman older than 50 to train for the maximum healthspan and lifespan benefits.’

On Instagram, Dr Sims writes: ‘Jump training and plyometric exercises involve explosive movements, such as jumping, hopping, and bounding, that help to improve muscle power, speed, and agility. Women often look aghast when they see that I put plyometric training front and centre in my “Menopause for Athletes” programming. We’ve been taught that we should be taking it down a notch when we get older, not turning it up. But that is just not true. Women of all ages benefit from including plyometrics in their training.’

It makes sense that the older you get, the more apprehensive you feel about impact training like plyometrics (another name for jump training), but Dr Sims is adamant you’re missing out on some big benefits. Here’s how to do it.

What is jump training?

Dr Sims explains: ‘[Jump training] isn’t your landing softly on your knees, this is like impact in the skeletal system. A colleague and a friend of mine Tracy Kissel did a PHD and post research on this, and is developing an app on it to show women how to jump to improve bone mineral density. Over the course of four months of this, women have gone from being osteopenic to normal bone density, so it’s a different type of stress. It’s ideal if your concern is decreasing bone density – which a lot of women do have as a concern because they lose about one third of their bone mass at the onset of menopause.

‘If you don’t do something as an intervention – so we see a lot of women are like, “Oh I’m going to go on menopause hormone therapy to stop bone loss.” Yeah, this can be a treatment, but I always look at an external stress that we can put on the body that is going to invoke change without pharmaceuticals – so, jump training.

Jump training benefits

‘And just to drive home that point about all ages: a systematic research review of the recent literature on plyometrics and older adults aged 58 to 79 reported that plyometrics often improved muscular strength, bone health, body composition, posture, and physical performance. None of the studies reported increased injuries or other adverse events from plyometric exercises among participants. The researchers concluded, “Plyometric training is a feasible and safe training option with potential for improving various performance, functional, and health-related outcomes in older persons.”‘

Jump training exercises – and how to get started

‘Plyometric exercises involve explosive, high-intensity movements, so it’s important to do them correctly to do them safely.

‘Let me also be clear that, unless you’ve already been engaged in some form of plyometric training, I’m not going to recommend that you start doing lots of bounding or jumping right out of the gate. You need to build up to it and establish good form. And always warm up beforehand so your muscles and connective tissues are ready to go.

‘To get the form down and condition your connective tissues to start jumping, you can start by simply bouncing up onto your toes and dropping into a squat. Start by standing with your legs hip to shoulder-width apart, feet flat on the floor. Bend your knees slightly and immediately straighten them again, bouncing up onto your tiptoes. Pause, then lower back down, dropping into a full squat, making sure that your knees track over your feet and don’t cave in. That will be your landing position when you start jumping.

Bounding is an effective form of jump training

‘Once you’re comfortable there you can do a depth drop, or reverse plyo drop. This is where, instead of jumping up onto a box or step, you start on a raised platform and step off to land on the ground. To do it, start on a step or box about 12 inches off the floor. Step off and land softly, immediately dropping into a squat position, again, keeping your knees straight ahead and not caving in toward each other. You can do 3 to 4 sets of 4 to 6 drops.

‘As you get comfortable absorbing the force of landing, you can start on the floor and do squat jumps. Stand with your feet wider than shoulder-width, feet turned out a little. Extend your arms straight in front of you. Squat down until your butt drops below knee level. Quickly extend your legs and jump into the air. Land softly, immediately dropping into another squat. Repeat 3 to 4 sets of 4 to 6 jumps, working your way up to one to two sets of 8 to 10 jumps. (Burpees are also a good way to sneak in squat jumps!)’

Once you’ve built up a solid and safe foundation, Dr Sims advises including the following exercises:

  • Squat jumps
  • Jump lunges
  • Burpees
  • Box jumps
  • Tuck jumps
  • Broad jumps
  • Plyo push-ups

Forms of training to practice alongside jump training

‘Jump training, heavy resistance training and sprint interval training are the three key things from a training standpoint,’ Dr Sims says.

Heavy resistance training

Heavy weight lifting should be reserved for compound lifts (using multiple muscle groups at once) to avoid injury, says Dr Sims

On Instagram, Dr Sims explains how to do heavy resistance training:

  • How many reps to go for: ‘Heavy lifting is defined as lifting 6 reps or less with as much weight as possible. It’s obviously not something that you jump straight into without building up to it, especially if you’re new to resistance training.
  • Best exercises to lift heavy: ‘A little goes a long way! You should not be lifting heavy for every single exercise. Instead, you want to reserve lifting heavy sh*t (LHS) for big, compound lifts like squats, deadlifts, and chest presses, which spread the load across multiple large muscles. That way you’re not overstressing any single muscle or joint.
  • Safety tips: ‘Safety is paramount here. Make sure you get expert instruction on load and technique. If you are new to lifting, book a few sessions with a trainer to learn proper technique and nail that down before adding weight.
  • How to progress with reps and sets: ‘LHS will not happen overnight. It can take months to build up to heavy loads if you are new. Expect to start with more moderate loads, lifting 2-3 sets of 8-15 reps to build a foundation and muscular endurance.
  • When to increase the weight you’re lifting: ‘After four to six weeks, you can bring the weight up and the repetitions down, so you’re lifting 5 sets of 5 reps. When that becomes comfortable, you can aim for 4 to 6 sets of 3-5 reps.’

Sprint interval training

Sprint interval training (SIT) can enhance the benefits of jump training by boosting your metabolism

  • Benefits of sprint interval training: ‘For menopausal women, high-intensity sprint interval training sessions can provide the metabolic stimulus to trigger the performance-boosting body composition changes that our hormones helped us achieve in our premenopausal years. One of the biggest benefits of SIT training is improvement in body composition (and cardiovascular health). SIT training increases lean muscle mass and reduces fat mass in a relatively short period of time. In a 2019 study published in Medicine & Science in Sports & Exercise, researchers had a group of postmenopausal women, ages 47 to 59, perform 20-minute bouts of SIT – alternating eight seconds of sprinting on a stationary bike at about 85% of their maximum heart rate with 12 seconds of easy pedaling – three times a week for eight weeks. By the study’s end, the women had lost fat, regained lean muscle mass, and improved their aerobic fitness by 12% after what amounted to only eight hours of exercise over eight weeks.
  • Heart rate zone to aim for: ‘The key here is INTENSITY. In high-intensity interval training, alternating short bursts of hard exercise are followed by relatively short recovery periods. So, if you’re using heart rate as a guide, anything that sends your heart rate above about 85% of your maximum is high intensity. When you reach your menopausal years, it’s very important to incorporate the shortest, sharpest form of HIIT: sprint interval training.
  • Duration of sprint intervals to aim for: ‘As the term indicates, SIT sessions include super-short, 10- to 30-second sprint-style efforts. They are extremely beneficial for both peri- and postmenopausal women.

Nutrition tips for women over 50

‘From a nutrition standpoint, protein is so important. When you start telling women they need to look at around 1-1.1g per lb which is around 2-2.3g per kg per day, they’re like, “Whoa, that’s a lot of protein!” It is, because you haven’t been conditioned to eat it. It doesn’t all have to be animal products; you can also look at all the different beans.

‘In order to build the muscle and to keep the body composition in a state that we want it to keep going for longevity, those are the big rocks: sprint interval training, heavy resistance training, jump training and protein.’

Exercising more than the mind: building a healthier student body

Exercising more than the mind: building a healthier student body

Students across East Asia are typically seen as diligent, smart and high-achieving, as Pisa scores show, but they also face overwhelming pressure to perform from parents, educational systems and society at large, and this can have impacts on their health.

A recent study in Hong Kong found that more than 90 per cent of students were getting less than the 60 minutes of exercise per day recommended by the World Health Organization. “This is due, in part, to the heavy emphasis parents place on their children’s academic results,” says Patrick Ip Pak-keung, a clinical professor at the University of Hong Kong’s paediatrics and adolescent medicine department who led the study.

In fact, the emphasis on academic performance is so deeply ingrained in Asian culture as an indicator of future success that students often swap adequate sleep and exercise for extended study hours – sacrificing their mental and physical health in the process.

Recognising that schools play a part in that equation, the Hong Kong Education Bureau recently issued a revised grading mechanism governing the assignment of secondary school places. A score for physical education (PE) is now a small part of the assessment, giving students more incentive to get and stay active alongside pursuing their academic goals.

According to Sam Wong Wing-sum, executive director of the Physical Fitness Association of Hong Kong, China, schools need to become more sports-friendly to develop children’s interest in physical activities from a young age. Besides having adequate facilities, the school environment also needs to encourage students to be active.

“Many institutions lack adequate facilities like playgrounds or sports equipment, leaving teachers to creatively adapt programmes within tight constraints,” says Carla Dos Santos, head of health at French International School (FIS). “Through partnerships with government facilities, our students enjoy access to a football pitch and track-and-field areas. The school also boasts two on-campus swimming pools and three gymnasiums, ensuring ample opportunities for physical engagement.”

Making enough time for physical activity is key. “School sports are an essential part of our educational mission” says Dr Arnold Leitner, deputy principal and head of the German international stream at GSIS. “With two or three hours of sports per week, we aim to awaken the joy of movement in all children and adolescents, and to convey that sports have a positive effect on their physical, social, emotional and mental development.”

Use these three stretches to help you achieve the most mobile hips of your life

I asked Caitlin Donato, a personal trainer and director of fitness for Pritiktin Longevity Center, why adulthood seems to mean poor hip mobility and increased imbalance in the hip joints for many people.

“Hip imbalances are common and lead to a restricted range of motion, which can cause poor posture, pain, or injuries,” says Donato.
