Boosting Exercise Intensity Reduces Mortality Risk, Study Suggests

If you want to live longer, you might want to push yourself just a little harder during your next gym visit: a new study reveals that putting extra strain on your body when you exercise matters more than squeezing in another session.

Researchers from the University of Basel in Switzerland and the University of Leicester in the UK have shown the intensity of your exercise can be more important than the time spent engaging in physical activity.

The team amassed three years of fitness tracker information covering a total of 7,518 adults in the US, with mortality data logged for an additional four years after that.

Higher intensity physical activity was found to be associated with comparitively lower risk of an early death from all causes, but the difference was most noticeable when it came to cardiovascular disease – think strokes, artery disease, and other heart problems.

“Higher intensity stimulates the cardiovascular system more,” says University of Basel sports scientist Fabian Schwendinger.

“This improves vascular function and cardiorespiratory fitness … the performance of the cardiovascular and respiratory systems.”

Boosting the speed of your regular jogs, or taking the stairs instead of the lift are just two ways daily activity can be given a healthy boost. To take one example from the data, an extra 150 minutes of brisk walking during the week could reduce mortality risk by as much as 28 percent, the study reports. That’s a significant benefit for not much extra effort.

The research chimes with previous studies that found greater intensity during exercising can have positive health effects, though the study also compared directly against the total duration of exercising.

“One of the great strengths of our study is that it included people with very different levels of fitness and health,” says Schwendinger.

“This means that everyone, regardless of whether they are very athletic or inactive, can benefit from the knowledge that intensity reduces mortality.”

The study authors also found that intense physical activity seems to be most beneficial when it’s done in one session, rather than spread out over the day.

To be clear, more exercise of any intensity is helpful. What’s more, there is such a thing as overdoing it. There will come a point when exercising harder won’t give you any extra years on the end of your life, and may actually start doing damage to your body instead.

“It’s not about people only living longer if they train extremely intensively, wear themselves out and are completely out of breath,” says Schwendinger.

The research has been published in the European Journal of Preventive Cardiology.

A new way to exercise is now open at the Smith River Sports Complex

A new way to exercise is now open at the Smith River Sports Complex

A new fitness court is now open for public use at the Smith River Sports Complex.

The fitness court, located at the Smith River Sports Complex, was completed in partnership with Aetna for its National Fitness Campaign across Virginia. It was created to cater to people ages 14 and older and with multiple levels of fitness in mind by allowing them to move at their own pace.

“We would like to thank Aetna for their support in bringing this important program to our community,” Henry County Director of Parks and Recreation Roger Adams said. “And for recognizing the need to support healthy lifestyles for all Virginians.”

The Smith River Sports Complex Fitness Court is one of the first communities in Virginia selected for the initiative, Adams said.

The fitness court base is a concrete pad with a connecting wall that features different equipment allowing users to work different muscles. The court is separated into seven different sections including: core, squat, push, pull, lunge, agility and bend.

Some of the different exercises possible on the fitness court include: mountain climbers, pushups, lunges at the lunge station, pullups, burpees and different core exercises.

“The fitness court is a wonderful example of partnerships across the public and private sectors to help break down barriers to accessible community programming,” Adams said. “Living a healthy lifestyle and taking preventative measures can help reduce the risk of developing chronic yet preventable diseases.”

“By practicing healthy habits through regular exercise on the fitness court with body weight training, individuals could significantly lower their risk of developing these diseases,” Adams said. “A body weight workout enhances coordination, balance and mobility in particular. We encourage everyone to walk, jog and cycle to our new fitness court and spend a little more time outside every day.”

“We know that when your physical health is better, your mental health is also better,” Henry County Board of Supervisors Iriswood District Representative Garrett Dillard said. “When you become a healthier community, that impacts your work, your school, your daily life.”

“We need to do better in Henry County,” Dillard said.

Henry County ranks 119 out of 133 counties in Virginia in terms of health outcomes, the county life expectancy is almost five years less than the state average, 42% of the population is considered obese and 26% of the county population reports having access to exercise opportunities, Dillard said.

“The key word there is opportunity,” he added. “Yes, we have a fair share of problems, but we also have an opportunity to solve them if we work together.”

“By partnering with Aetna, the National Fitness Campaign … the county is now able to offer free, accessible and high-quality fitness equipment for people of all ages and abilities,” Dillard said. “The fitness court is designed to bring the benefits of exercise to everyone, regardless of fitness level, and its right here in our community.”

Along with the fitness court, users can download the free Fitness Court App which provides a coach-in-your-pocket and enhances the outdoor gym with a digitally supported wellness experience.

The Martinsville-Henry County YMCA also plans to hold classes on the fitness court in the future.

“This is sure to be the first of many initiatives that will encourage healthy habits in our community,” Dillard said. “I encourage everyone to take full advantage of this incredible resource as we work together to improve the health and quality of life for everyone in our community.”

High Cardiorespiratory Fitness Linked to Lower Dementia Risk

High Cardiorespiratory Fitness Linked to Lower Dementia Risk

WEDNESDAY, Nov. 20, 2024 (HealthDay News) — High cardiorespiratory fitness (CRF) is associated with better cognitive performance and lower dementia risk, according to a study published online Nov. 19 in the British Journal of Sports Medicine.

Shuqi Wang, from the Tianjin Medical University in China, and colleagues examined the association of CRF with cognitive function and dementia risk, accounting for genetic predisposition for dementia. A total of 61,214 dementia-free participants within the U.K. Biobank, aged 39 to 70 years, were followed for up to 12 years. The CRF score was estimated using a six-minute submaximal exercise test and divided into age- and sex-standardized tertiles.

The researchers found that high CRF was associated with better global cognitive function compared with low CRF (β = 0.05). Overall, 553 individuals developed dementia during the follow-up period. The incidence rate ratio was 0.60 for all dementia for high CRF versus low CRF; dementia onset was delayed by 1.48 years among people with high versus low CRF. Higher CRF attenuated all dementia risk by 35 percent among those with a moderate/high polygenic risk score (incidence rate ratio, 0.65).

“Our findings suggest that maintaining favorable CRF could be a strategy for the prevention of dementia, even among people with a high genetic predisposition,” the authors write.
