Exercise may lower the ALS risk for men — but not women: new study
Moderate or vigorous exercise may lower the risk of ALS, a fatal disease, for men but not women, new research finds.
The study, published Wednesday in Neurology, the medical journal of the American Academy of Neurology, followed 373,696 Norwegian people for about 27 years.
Participants recorded their physical activity, ranging from sedentary to moderate to intense. During the follow-up period, 504 people developed ALS.
Adjusting for lifestyle factors that can affect the risk of ALS, like smoking and body weight, researchers found that male participants who reported moderate levels of physical activity had a 29% lower risk of ALS while high levels of physical activity meant a 41% lower risk.
The study only found an association between physical activity and the risk of ALS in male, not female participants.
Researchers also analyzed participants’ resting heart rates, an indicator of overall fitness, finding that those with the lowest rates had a 32% reduced risk of ALS compared to participants with higher rates.
Study author Dr. Anders Myhre Vaage, of Akershus University Hospital in Norway, notes that the diagnosis of ALS in high-profile athletes has spurred the thinking that strenuous physical activity is an environmental risk factor that leads to the development and early onset of the disease.
One study found that NFL players are four times more likely to develop and die from ALS than the general adult male population.
Research has also shown that ALS risk genes are activated by exercise, adding to the growing debate about the relationship between physical activity and ALS.
“There have been conflicting findings on levels of physical activity, fitness and ALS risk,” Myhre Vaage said. “Our study found that for men, living a more active lifestyle could be linked to a reduced risk of ALS more than 30 years later.”
What is ALS?
ALS, also referred to as Lou Gehrig’s disease, for the Hall of Fame baseball player who died of it in 1941, is a progressive neurodegenerative disease. With ALS, the nerve cells that control muscle function deteriorate, and patients gradually become unable to walk, move, eat, speak and breathe, leading to partial or total paralysis and death.
There is no known cure for ALS — the average life expectancy after diagnosis is two to five years.
Myhre Vaage hopes the study’s findings lead to more research on ALS risk factors.
“Our findings show that, for men, not only do moderate to high levels of physical activity and fitness not increase the risk of ALS, but that they may be protective against the disease,” he said. “Future studies of the connection between ALS and exercise are needed to consider sex differences and higher or professional athlete physical activity levels.”
Other research suggests that the type of physical activity is an important factor in mitigating ALS risk. For example, one study proposed that golfing and gardening put men at three times greater risk of developing ALS.
That study found that golfers and gardeners are especially prone because of frequent exposure to pesticides, which prior research has tied to the disease’s development.
Famous people who have been diagnosed with ALS
According to the ALS Association, someone dies from ALS and someone is diagnosed with it every 90 minutes — and celebrities are not immune to its punishing effects.
Footballer Dwight Clark and physicist, cosmologist and author Stephen Hawking have lost their battles with the disease, while singer Roberta Flack, sportswriter Sarah Langs and former Chicago Bears football player Steve McMichael are still fighting.

Fitness: Is mindfulness the key to a more enjoyable workout?
If exercise pushes you so far outside your comfort zone that physical activity is associated with pain more than pleasure, there’s little motivation to get off the couch.
Article content
There’s no shortage of rumination about why more than half of Canadians don’t meet the recommended 150 minutes of moderate to vigorous physical activity per week. Lack of time is a common excuse, but there are plenty of busy people who exercise regularly. Access is another often-stated barrier, though most Canadians can safely exercise outdoors or in the privacy of their own home should other fitness facilities not be within an easy commute.

What’s often ignored is the role enjoyment plays in exercise adherence. For those who revel in a tough workout, the idea some people hate to sweat may seem strange. But if exercise pushes you so far outside your comfort zone that physical activity is associated with pain more than pleasure, there’s little motivation to get off the couch.
Once exercise becomes coupled with discomfort, getting reluctant exercisers to find pleasure and enjoyment in physical activity is an uphill battle. To help improve its appeal, researchers have been looking at the effectiveness of something called “extrinsic strategies” to promote better exercise adherence. Defined as “environmental manipulations of the exercise experience that fall outside of the FITT principles,” extrinsic strategies are more about the mental, rather than physical aspects of exercise. In short, the focus is less about the frequency, intensity, time and type of exercise, and more about the role feelings play in the adoption of a regular workout routine.
To be clear, we’re not talking about taking the effort out of exercise. Extrinsic strategies work on altering the perception of effort. Even more granular, it’s important to alter how effort is perceived during, not after, a workout. There’s a marked difference in how people feel once they wipe the sweat off their brow compared to when they’re grinding it out just hoping to finish. And while some people use the feeling of accomplishment that comes after a tough workout to motivate their return to the gym, others can’t get past the memory of how uncomfortable it felt in the moment.

One of the extrinsic strategies to improving the exercise experience is focusing on external stimuli instead of how the body feels. Music is a popular distraction, which is why so many exercisers listen to their favourite playlists. Another option is exercising outdoors where nature works its magic at diverting exercisers from the internal sensations of effort. Exercising with a friend or within a group also helps. But contrary to using external distractions to dampen the effort of exercise, is the novel idea of leaning into how your body feels during a tough workout.
Mindfulness is defined as paying attention to what’s happening in the moment while also being open to how the body responds physically and mentally to the current experience. In other words, instead of trying to disassociate from the feelings of effort, mindfulness aims to accept and acknowledge the exertion it takes to complete a workout.
The idea that mindfulness is effective at improving exercise adherence is gaining traction, with initial studies suggesting it has merit, but mostly when exercising at lower intensities. Learning to accept and become comfortable with the feelings associated with physical exertion could be a crucial first step in finding pleasure in exercise.

A recent study published in the Journal of Sports Sciences recently tested the effectiveness of mindfulness in enhancing the exercise experience. The goal of the research team was to see if mindfulness “could prove a useful pleasure enhancing strategy during exercise.”
A test sample of 34 recreationally active men and women were divided into two groups. One group was equipped with a recording taken from Headspace, a popular meditation and mindfulness app, that focused exercisers on tuning into their body and its movement. The control group was without any mindfulness tools.
Both sets of exercisers were asked to follow a 1.5-mile loop through a local park at a self-selected intensity they could sustain for 20-25 minutes. Heart rate was continually monitored, and study subjects were asked to check in with how they felt at two points during the walk (at 0.5 and one mile).
Results indicated listening to a mindfulness recording led to a more pleasurable exercise experience than walking the loop without. That positive response to exercise continued after the workout finished, another sign the mindfulness guided walk produced the kind of enjoyment that could encourage exercisers to walk more often.
Learning to appreciate the feelings associated with effort is an interesting strategy to introduce, especially to new exercisers who often negatively perceive the physical sensations that occur during a workout. With more practice accepting, instead of tuning out, those feelings, a greater number of novice exercisers could become more tolerant of the effort required to improve overall fitness. It’s also an interesting approach for seasoned exercisers who generally rely on disassociating from the intense feelings of a hard workout.
Acknowledging, accepting and appreciating the effort of being physically active are tools every exerciser can lean into when the going gets tough. More importantly, it could be part an improved strategy to get more Canadians enjoying the 150 minutes a week they spend working up a sweat.

This type of exercise suppresses hunger in women more than men, study proves
Find yourself with a bigger appetite on rest days than after logging your hardest workout of the week? Same. It usually takes me an hour or two to feel hunger after an intense session, and while there are plenty of existing studies that have attributed this to a decrease in the hunger hormone grehlin and an increase in the hormone peptide YY, which helps you feel fuller for longer, new research suggests women are more susceptible to this response than men.
Granted, the study was conducted on only a small sample of participants (eight males and six females), but this is the first review to have included women at all, and the findings were notable.
The method was pretty straightforward: participants were asked to fast overnight, before completing bouts of cycling at varying levels of intensity the next morning. These were then followed up with blood tests (to measure amounts of lactate) and self-reports to analyse appetite levels.
Results showed that the females had higher levels of total ghrelin (the hormone that makes you feel hunger) at baseline compared to the males, while they also had ‘significantly reduced levels’ of acylated (AG) ghrelin after intense exercise compared to males. Ghrelin levels were, in fact, much lower in both males and females after intense exercise compared to moderate exercise, meaning that all participants felt ‘less hungry’ after high-intensity exercise compared to after moderate exercise, but this was even more significant for women.
‘We found that moderate intensity exercise either did not change ghrelin levels or led to a net increase,’ the study noted. The authors added that exercise above your lactate threshold may be necessary to elicit a suppression in grehlin. Lactate threshold is the point at which lactate builds up in your bloodstream faster than your body can remove it – it occurs during high-intensity exercise.
Why is this useful to know? The author of the study, Kara Anderson, PhD, says: ‘Our research suggests that high-intensity exercise may be important for appetite suppression, which can be particularly useful as part of a weight loss programme. Exercise should be thought of as a “drug”, where the “dose” should be customised based on an individual’s personal goals.’
