Too Much Sitting Harms the Heart, Even in Folks Who Exercise

MONDAY, Nov. 4, 2024 (HealthDay News) — There’s just something about sitting.

New research shows that too much time on sofas and chairs harms the heart — even among people who get the minimum recommended amount of daily exercise.

“Taking a quick walk after work may not be enough” to offset the health dangers of sitting, said study lead author Chandra Reynolds. She’s a professor of psychology and neuroscience at the University of Colorado in Boulder.

Her team published its findings recently in the journal PLOS One.

The data comes from an ongoing study of over a thousand former or current Coloradans, 730 of who are twins. Reynolds’ team focused on participants aged 28 to 49.

Study lead author Ryan Bruellman said the cohort was relatively young, because “young adults tend to think they are impervious to the impacts of aging. But what you do during this critical time of life matters.”

Bruellman is now a PhD candidate at the University of California, Riverside.

A lot of the participants were sitting a lot of the time: An average of almost nine hours per day, according to the study.

Exercise rates ranged from 80 and 160 minutes of moderate physical activity per week and less than 135 minutes of vigorous exercise weekly. 

The Boulder team then assessed each person’s “heart age” using two key heart health indicators: total cholesterol/high-density lipoprotein and body mass index (BMI).

The result: As sitting time increased, heart aging did, too.

Even when folks met minimum daily exercise recommendations — about 20 minutes per day of “moderate” exercise — the deleterious effect to the heart of all that sitting didn’t budge.

Adding in “vigorous” exercise (for example, running or cycling) for about 30 or more minutes per day did seem to help counteract the harms from sitting, however. But it still didn’t bring those harms back to zero.

According to a news release from the university, data from the twins in the study suggests that “replacing sitting with exercise seemed to work better to improve cholesterol than simply adding exercise to a full day of sitting.”

The researchers’ suggestions for folks who sit a lot: Try using a standing desk at work, get in at least 30 minutes of vigorous exercise per day or add in strenuous workouts on your days off as a “weekend warrior.”

Is morning or evening exercise better for weight loss? Researchers find out

Is morning or evening exercise better for weight loss? Researchers find out

Any exercise is better than no exercise when it comes to losing weight, and ultimately, you should go when you know you can stay consistent because it fits in your schedule. For some people, that’s first thing in the morning, and for others, that’s in the evening after work. Others like to mix it up depending on what’s on the agenda.

In a thought-provoking study, researchers found that moderate-to-vigorous physical activity, such as running, cycling, sports, and brisk walking, is protective against obesity. However, what’s less clear is the optimal time to get those muscles moving and break a sweat. Does it really matter that much? Are we overthinking it? Researchers dived deeper to understand more.

The study

In a study published in the journal Obesity, researchers placed 5285 participants into three different groups based on when they did most of their exercise:

  • Morning workout group
  • Midday workout group
  • Evening workout group

The researchers tested the patterns and associations between the timing of moderate-to-vigorous physical activity and obesity. They compared how exercising at different times related to both waist size and body weight.

The results

The results revealed the following:

  • Morning exercise seemed to be the most effective for weight control.
  • Those who were the most active in the morning had a lower body mass index and smaller waistlines overall, even when they did the same amount of exercise as those who mostly exercised midday or in the evening.
  • Exercising at any time of the day was beneficial for obesity, but morning exercisers had the strongest link to lower obesity.

Meeting the exercise guidelines

Among the individuals who met the weekly exercise guidelines of at least 150 minutes every week, their average body mass index was:

  • Morning — 25.9
  • Midday — 27.6
  • Evening — 27.2

For those who met the exercise guidelines, their waist size was:

  • Morning — 91.5 cm
  • Midday — 95.8 cm
  • Evening — 95.0 cm

Overall, morning exercisers were leaner.

The takeaway

Exercise helps prevent obesity and promotes weight loss, no matter what time you get your muscles moving. This study shows that morning exercise may be superior and offer an extra advantage for weight loss compared with midday or evening exercise. In this study, morning exercisers had lower BMIs and smaller waists. There’s more to the weight-loss picture than exercise alone; other factors like nutrition, hormones, toxicity, sleep, certain medications, and stress also play a role.

One minute of this exercise could be ‘six times better’ than walking for heart health, scientists reveal in new study

Movement is key to longevity. We bang on about it a lot, but it really is the best thing we can do for our physical and mental health in the short and long term. But how much movement we should be doing is up for discussion.

Studies have shown that exercising for long periods of time isn’t always necessary, which is good news, as so many of us are busy and time-poor. Now, new research shows that even just one minute of intense exercise is better for our heart health than walking for much longer amounts of time.
