Scientists Find This Type of Exercise Cuts Heart Disease Risk in Half
  • A few short bursts of exercise throughout the day may reduce heart disease risk by 50%, according to new research.
  • Women specifically showed the most pronounced effects of short bursts of activity.
  • Experts explain the findings.

If you struggle to get your steps in or to find enough time in the day to hit the gym, you’re in luck. New research finds that even a few short bursts of exercise may cut your heart disease risk in half.

A study published in the British Journal of Sports Medicine used data from more than 22,000 people between 40 and 79 years old from the UK. These participants wore physical activity trackers for nearly 24 hours a day between 2013 and 2015. Data from hospital and death records were also used to keep track of the participants’ heart health to look for major cardiovascular events, such as heart attack, heart failure, and stroke.

Women, in particular, showed more obvious effects from the short bursts of activity. That is, women who did at least 3.4 minutes of short bursts of vigorous activity per day were found to be 45% less likely to have a major cardiovascular event. When exercising between 1.5 and four minutes a day (with bursts lasting up to one minute), researchers saw an association of a 51% reduced risk for heart attack and a 67% reduced risk for heart failure, compared to those who did not perform this type of exercise.

While women saw the most impact on their heart health, the male participants also saw some benefits of this activity. With a minimum of 2.3 minutes of activity per day, researchers found that men lowered their risk for major cardiovascular events by 11%; performing 5.6 minutes a day of this type of movement saw that men were 16% less likely to experience a major cardiovascular event.

“Making short bursts of vigorous physical activity a lifestyle habit could be a promising option for women who are not keen on structured exercise or are unable to do it for any reason,” study author Emmanuel Stamatakis, Ph.D, director of the Mackenzie Wearable Hub at the Charles Perkins Centre and the Faculty of Medicine and Health at the University of Sydney, said in a statement.

Exercise helps the heart work better, says David Sagbir, M.D., board-certified cardiologist and spokesperson for Avocados-Love One Today. “Regular physical activity strengthens the heart muscle and improves blood flow which can help reduce risk factors for developing heart disease such as lowering blood pressure, managing cholesterol levels, helping regulate blood sugar, and impacting visceral adipose tissue—the type of body fat that surrounds organs and can increase our risk of heart disease,” he explains.

So if you want to focus on boosting heart health, Dr. Sagbir says that the best exercise for reducing heart disease risk is aerobic—the kind that increases your heart rate and gets you breathing more heavily. “I am a big fan of getting your heart pumping and circulation going with a daily walk,” he advises. And, as Dr. Sagbir points out, every micro-walk counts.

Walking is a proven means of reducing many of the major risk factors of heart disease, including blood sugar, blood pressure, cholesterol levels, and a high body mass index, Dr. Sagbir continues. “In addition to the cardiovascular benefits, improvements in cognitive function and memory, mood and stress, as well as longevity have all been documented,” he says (and recent research shows that walking could even add over a decade to your life!). Walking calls for no equipment, does not require a gym membership, and is adaptable to busy lifestyles, which is why Dr. Sagbir highly recommends getting your steps in.

In addition to walking, Cheng-Han Chen, M.D., board-certified interventional cardiologist and medical director of the Structural Heart Program at MemorialCare Saddleback Medical Center, recommends jogging, taking the stairs, biking, and swimming/water aerobics. “It is also helpful to incorporate some strength training, as this also helps to improve the function of blood vessels,” he advises.

The bottom line

This study shows that even small amounts of higher-intensity exercise, just a few minutes at a time, can potentially provide a significant benefit to heart health, says Dr. Chen. “These are activities that can be incorporated into even a busy schedule. One can take brisk one-to-two-minute walks up and down the stairs, or get exercise through normal daily activities such as carrying heavy groceries,” he explains.

These findings are also compelling because of changes that take place during the menopause transition and how exercise may be particularly beneficial to women in this life stage, notes Dr. Sagbir. “Women experience changes during the menopausal transition that put them at greater risk for heart disease,” he says. For example, high blood pressure, a major risk factor for heart disease, significantly increases after menopause, he explains.

To reduce heart disease risk, Dr. Chen recommends engaging in regular physical activity, eating a nutritious balanced diet, getting an adequate amount of quality sleep, maintaining a healthy weight, avoiding tobacco and alcohol, and managing blood pressure and cholesterol numbers.

Fitness expert shares 5 exercises your parents need to do in their 60s for strong knees. All you need is a chair

As your parents grow old, their joints start aching, and bones become weak. While walking and simple daily activities are great for keeping them active, it is also important for them to strengthen their bones. Fitness expert and nutritionist Rishabh, who often shared workout videos to help his followers become active, recently shared a clip in which he shared five exercises he designed for his mother to help her strengthen her knees at 62.

Fitness expert shared 5 exercises he designed for his mom to build strong knees.

5 exercises to strengthen your parents’ knees

Rishabh shared the clip with the caption, “5 exercises I get my mother to do to have her build strong knees. Share this with your parents, friends and anyone else who can make use of this routine. I hope this helps.” He even shared the steps to the workouts. All you will need is a chair. Here are the five exercises he suggested:

1. Calf raises

To do the calf raises, the fitness expert made his mother move the entire weight onto the toes while going up. While coming down back to her heels, he made her slow down the descent. He suggested doing the exercise for 18 to 20 repetitions.

2. Hip flexor lift

Take a chair and sit down. Now, lift one leg at a time using only the hip. Keep alternating for 20 repetitions.

3. Seated toe raises

Make your parents sit closer to the edge of the chair and ask them to plant their feet on the ground. Now, they will have to raise their toes completely off the ground, as much as they can manage. Slowly bring the toes back down and do the exercise for 20 repetitions.

4. Knee extensions

Place your feet firmly on the ground while sitting on a chair. Then, extend your kneed parallel to the ground, one at a time. Pause your leg for a fraction of a second in the air, and then apply some resistance on your parent’s leg from the top. Ask them to push it back. Then, slowly bring the leg down to the ground and repeat the exercise.

5. Hamstring curls

For this exercise, stand while holding the back of the chair for support and bend the knee to a 90-degree angle [parallel to the ground]. Then, do the same drill. Apply some pressure on the leg and ask them to push back and slowly bring their leg down. Repeat.

Things to keep in mind

In the end, the coach added that he finishes off the routine by asking his mom to do a 5-minute backward walk. Additionally, he suggested that if you are assisting your parents, make sure the surroundings are safe and clean to avoid any injuries.

Researchers at University of Tsukuba identified a previously unconfirmed gas exchange threshold in rats and demonstrated that this threshold, together with the lactate threshold, serves as an indicator of moderate-intensity exercise to determine the effectiveness of training in enhancing aerobic performance.

The study is published in Medicine & Science in Sports & Exercise. This achievement is fundamental for basic research on exercise. It will be useful for researchers in the field of health and fitness promotion as it provides a useful moderate-intensity index for rats.

During incremental aerobic exercise, there are thresholds where blood lactate levels begin to rise, and CO2 production increases rapidly relative to O2 uptake. The former threshold is termed the lactate threshold (LT), and the latter, the gas exchange threshold (GET). In humans, these thresholds are moderate-intensity exercise indices, with LT and GET at 45%–74% of the maximal oxygen uptake (VO2max). Training at or above these thresholds improves aerobic performance.

In contrast, in rats, LT has been identified, but GET is not known yet. Furthermore, it is unclear whether the rat GET and LT can be useful indicators of exercise intensity similar to the thresholds in humans.

The researchers previously established a rat model for identifying the LT during running exercise. This study aimed to simultaneously identify LT and GET by integrating this LT model with the standard human GET identification method, known as the V-slope method.

Subsequently, the relationships among the identified GET, LT, and VO2max, as well as the changes in these thresholds following aerobic training below or above the LT, were examined. The results showed that GET and LT in rats occurred synchronously at intensities ranging from 41.0% to 65.5% VO2max, and that the maximal (VO2max) and submaximal (GET, LT) aerobic capacities were enhanced only in rats that trained at intensities above the LT.

These results suggest that the GET and LT in rats are valid indices of moderate-intensity exercise in training prescription to enhance aerobic performance as in humans. The findings of this study are expected to serve as a catalyst for further research in the field of rat studies focused on exercise intensity, ultimately contributing to the advancement of human exercise prescription strategies. In particular, the noninvasive and easily identifiable nature of the GET from the exhaled gas suggests a wide range of potential applications.
