Discussion of Fight-Flight-or-Freeze Responses Based on a Combination of Life Experience and Empirical Evidence Yesterday afternoon, I wrote a post, "Exercise May Promote Gene Expression of Feel-Good Chemicals" based on new research from McMaster University ( Allison et al., 2019 ), which found that the combination of vigorous aerobic exercise and weight-lifting caused a chain reaction along the kynurenine pathway that resulted in the synthesis of more serotonin and a decreased depression risk.
Source: Rido/Shutterstock This study ( Allison et al., 2019 ) investigated the impact of an exercise training program that combined strength training (weight-lifting) and high-intensity interval training (HIIT) on skeletal muscle gene expression of certain proteins called “transcription factors.” These proteins help regulate the gene expression of kynurenine aminotransferase (KAT) and plasma concentrations of tryptophan metabolites called "kynurenines." Many people associate tryptophan with the folklore-based misconception that the tryptophan in turkey will make you drowsy after eating Thanksgiving dinner.
After dinner, sometimes Rich will join me in the living room, where we’ll catch up our days, read, or play a game, and of course, talk about the kids. With the extra time you hopefully have without your youngest kid at home, maybe you can try a new hobby or learn a craft.
Sure enough, writing about arousal put students in what the study called a “mating mood.” People in a mating mood were motivated to “find someone attractive you are interested in,” while students in the happiness group were more motivated by “enjoying yourself and having fun.” Then participants imagined they owned a fictional workout tracker and rated their likelihood of sharing various posts.
“But information itself can lead to these effects, not only in people’s subjective experience, but also in their physiology.” To test if the outcomes were unique to CREB-1 or if they would extend to other paradigms, the authors conducted a second study centered on the FTO gene, one of the best-studied genetic risk factors for obesity.
According to Hoeppner et al., this is the first large study designed to investigate if self-administered, text-entry-based positive psychology writing exercises can significantly improve in-the-moment happiness for people recovering from problematic substance use.
The results: People who replaced just 30 minutes of sitting per day with low-intensity physical activity lowered their risk of an early death by 17 percent, according to the study published online Jan. 14 in the American Journal of Epidemiology .
Details : 455 adult patients from ages 18-65 with a diagnosis of major depression who did moderate intensity aerobic exercise for 45 minutes three times a week showed a large overall anti-depressant effect, according to the study summarized here .
Including in their study the role of relatedness, or psychological need satisfaction in exercising with others, the Canada-UK team believed that college students more connected on Facebook, who also enjoyed sharing their exercise with other people, would have deeper and more lasting exercise motivation.
And anyone who is having these thoughts and the myriad of unpleasant emotions (e.g. shame, guilt, sadness) that go along with it will naturally start avoiding people, places, and things that involve movement because of the fear of causing more pain.
"The people in this study were older, already had cognitive [mental] impairments and cardiovascular risk factors, and they were sedentary." Fargo, who was not involved in the research, described the findings as "great news." He said that's in large part because this was a clinical trial that actually put exercise to the test.
In short, we found a bunch of people who were attending CrossFit and a bunch of people who were attending Gold's, both at various gyms around the US, and asked them to participate.
My million-dollar question for you: Did the intensity of aerobic exercise during the 35 minutes of walking, jogging, or cycling on a stationary bike (three times a week for six months) make a difference on the degree to which aerobic exercise promoted improved executive functioning in adults at risk for cognitive decline?"
"The data shows that moderate exercise in the evening is no problem at all," Jan Stutz, a doctoral student in Spengler's research group and lead author of this meta-analysis said.
Some studies have shown a link between over-use of digital technology and harmful effects on the immune system, such as that published by myself and colleagues in PLOS ONE in 2015,4 and others have shown that overuse of such technology is associated with poor lifestyle choices (bad diet, poor sleep).5 How these negative influences interact with the benefits of exercise remains to be seen.
What kinds of social media networks are most effective for promoting healthy levels of physical activity, competitive interactions or supportive social contacts? The most encouraging finding was that social comparison — that is, friendly competition — was really effective at improving people’s levels of physical activity.
"A lot of young kids use energy drinks when they exercise, a time when you need your arterial function to be at its top," said lead researcher Dr. John Higgins. Energy drinks that reduce the vessels' diameter, in effect, restrict blood flow and oxygen delivery, he explained.
The latest recommendations from HHS are based on the 2018 Physical Activity Guidelines Advisory Committee Scientific Report which lays out specific types of aerobic and muscle-strengthening exercise along with how much and what types of physical activity are optimal for promoting better health outcomes in a wide range of demographic groups.
Many healthy behaviors help prevent the deterioration of aging, as explained in the book, Improve Your Memory for a Healthy Brain. Recent research indicates that exercise in older age can prevent the immune system from declining and protect people against infections.
For the study, researchers from the Cleveland Clinic medical center analyzed data from more than 122,000 patients who underwent exercise stress tests between 1991 and 2014. Participants who performed better on the stress test were significantly more likely to live longer.
