Strength training exercises improve both physical & psychological health

Poor muscle strength predicts increased vulnerability to both physical & psychological health problems and earlier death, in addition to the contribution of poor aerobic, heart-lung fitness.  This is true for both men & women and for all assessed age ranges.  Mechanisms underlying these effects are probably multifactorial, including metabolic/biochemical, neurological & psychological factors.  Research studies have assessed overall muscular strength in a variety of ways including grip strength, push-ups, chair-stands, and squat weight-lifts.  Happily, muscle strengthening interventions can yield major benefits across multiple health domains.  Here are a dozen interesting papers addressing these areas published in the last few years:

   Social networks: social identity & the importance of both formal & informal groups (what can we do?)

 

key points: 

the social identity model highlights the value of group membership (more & less formal) for both psychological & physical wellbeing - are there groups you would like to join (or initiate) and are there helpful ways you can increase the sense of the importance to you of some of the groups you're a member of (for example by increasing your involvement with them).

Social relationships, group memberships and health: what we can do

I recently wrote a blog post "Social relationships, group memberships and health: background", where I described some of the mental & physical health benefits of group membership.  I mentioned too the recent research study "Greater number of group identifications is associated with healthier behaviour" where the authors write:"What is already known on this subject? Researchers from a number of disciplines – especially social epidemiologists – have investigated the link between social ties and health behaviour in the past. These researchers have shown that, overall, greater ties predict healthier behaviour.

Social relationships, group memberships and health: background

We know that relationships are important for wellbeing, for protection against & treatment of psychological disorders, and for improving mortality - see, for example, blog posts on this website such as "Strong relationships improve survival as much as quitting smoking", "Be the change you want to see in the world" "Friendship: science, art & gratitude".
