New research suggests physical exercise has ‘little’ mental benefits

Need a brain boost? Fitness may not be for you!

It is more common than not to hear exercising will provide a range of mental health benefits, but new research suggests there is “little evidence” showing a correlation between improved cognitive health and physical exercise.

Analyzing data from over 100 individual trials involving more than 11,000 “healthy participants” found “inconclusive evidence” that physical exercise improves cognitive ability, according to findings published by Nature Human Behaviour.

“After re-analyzing 24 meta-analyses of RCTs (randomized controlled trials), including a total of 109 primary studies and 11,266 healthy participants, we found inconclusive evidence supporting the existence of a potential cognitive benefit derived from the regular practice of physical exercise in healthy populations,” Lead researcher Luis Ciria and his team found during their analysis.

Ciria, a postdoctoral researcher with the Mind, Brain and Behavior Research Center at the University of Granada in Spain, said his team’s findings “suggest” claims linking exercise to improved cognitive ability should be advised with caution until “more reliable causal evidence accumulates.”

Ciria and his team opted to conduct an umbrella analysis to reevaluate the data presented in 24 different RCTs and found that these trials often have too few participating subjects to evaluate appropriately and may be prone to bias, frequently miss contradictions or mixed findings.

“In line with recent accounts, we believe this exponential accumulation of low-quality evidence has led to stagnation rather than advance in the field, hindering the discernment of the real existing effect,” Ciria wrote.

Some studies compared the exercise group to an utterly inactive group, while others compared it to less active groups.

As expected, considerable benefits were typically detected when the exercise group was compared to the sedentary groups.

Other studies found that physical exercise had a significant benefit when the initial mental performance of the experimental group was lower than that of the control group.

By re-evaluating the data with these possible biases in mind, the researchers found little benefit to the healthy person’s brain because they exercised.

Short Exercising ‘Snacks’ Are Just as Balanced as a Entire Exercise. Here is Why

“Movement snack” is a catch-all expression for any bodily action you do in definitely limited bursts, say one to 10 minutes, as opposed to additional conventional conditioning routines that have you doing exercises for lengthier stretches.

To determine their results, researchers analyzed irrespective of whether good sleep wellness was similar to how properly people adopted various lifestyle modifications in a 12-month weight-decline system that provided 125 grown ups with an common age of 50 decades. Virtually all of the participants ended up women, 81% have been white and all fulfilled requirements for overweight or obesity, according to their entire body mass index.

What constitutes “good sleep”

Scientists measured participants’ sleep behavior at the commencing of the program, at six months and then all over again at 12 months via individual questionnaires, a snooze diary and seven-working day readings from a system worn on their wrists that tracked snooze, waking exercise and relaxation.

Participants received a score of “good” or “poor” primarily based on 6 steps of rest:

  1. Regularity
  2. Fulfillment
  3. Alertness

  6. Period

A rating of -6 was then calculated for just about every participant, with 1 stage additional for just about every “good” measure of slumber well being. Individuals experienced an average sleep well being rating of 4.5 out of 6 at the start of the analyze, at 6 months and at 12 months. 

Scientists observed that much better rest health was connected with “higher charges of attendance at group interval classes, adherence to caloric intake goals and enhancement in time used executing reasonable-vigorous actual physical exercise,” according to the study.

“We experienced hypothesized that rest would be related with life style modification however, we did not anticipate to see an association amongst sleep well being and all 3 of our measures of life style modification,” Kline explained. “Although we did not intervene on slumber health in this study, these outcomes counsel that optimizing rest may possibly direct to

Exercise Might Ease Side Effects of Breast Cancer Treatment | Health & Fitness

FRIDAY, Nov. 25, 2022 (HealthDay News) — An exercise program, even if it’s not as intense as national guidelines suggest, could help breast cancer patients undergoing radiation therapy reduce fatigue and have a better quality of life, new research suggests.

Researchers from Edith Cowan University in Australia included 89 women in this study — 43 participated in the exercise portion; the control group did not.

Exercisers did a 12-week home-based program. It included weekly resistance training sessions and 30 to 40 minutes of aerobic exercise.

Researchers found that patients who exercised recovered from cancer-related fatigue more quickly during and after radiation therapy compared to the control group. Exercisers also saw a significant increase in health-related quality of life, which could include measures of emotional, physical and social well-being.

“The amount of exercise was aimed to increase progressively, with the ultimate target of participants meeting the national guideline for recommended exercise levels,” said study leader Georgios Mavropalias, a postdoctoral research fellow in the School of Medical and Health Sciences.

“However, the exercise programs were relative to the participants’ fitness capacity, and we found even much smaller dosages of exercise than those recommended in the [Australian] national guidelines can have significant effects on cancer-related fatigue and health-related quality of living during and after radiotherapy,” Mavropalias said in a university news release.

The Australian national guidelines for cancer patients call for 30 minutes of moderate intensity aerobic exercise five days a week or 20 minutes of vigorous aerobic exercise three days a week. This is in addition to strength training exercises two to three days a week.

About 1 in 8 women and 1 in 833 men are diagnosed with breast cancer during their lifetimes, according to Living Beyond Breast Cancer, a Pennsylvania-based nonprofit organization.

The study showed a home-based exercise program during radiation therapy is safe, feasible and effective, said study supervisor professor Rob Newton, a professor of exercise medicine.

“A home-based protocol might be preferable for patients, as it is low-cost, does not require travel or in-person supervision and can be performed at a time and location of the patient’s choosing,” he said in the release. “These benefits may provide substantial comfort to patients.”

Study participants who started an exercise program tended to stick with it. They reported significant improvements in mild, moderate and vigorous physical activity up to a year after the program ended.
