Running makes your bone marrow younger

While runners may enjoy enhanced cardio fitness, they also often share concerns pertaining to how healthy their chosen high impact activity is for their joints, especially as they age. Now, research from Deakin University in Victoria has found that long distance runners enjoy significantly younger bone marrow than not only non-exercisers, but also highly active cyclists. For every 9km a person regularly ran, a year was shaved off the age of their bone marrow. Younger marrow is linked with protection against the development of pelvis, vertebrae, thigh and hip problems as well as other chronic conditions, such as diabetes and osteoporosis.


It can be tough: telling your clients the truth about losing weight

It may be tempting to put an overly positive spin on things when discussing with clients what they need to do to achieve weight loss, but doing so may do neither of you any favours, according to research from the US.

Psychologists from Drexel University found that people who were told that losing weight would be incredibly challenging achieved greater success in the short term than their peers.


The big effects of small changes

Swapping just half an hour a day of sitting with light physical activity could be enough to reduce risk of death from cardiovascular disease by 24% according to recent Swedish research.

Using activity trackers, the team from the Karolinska Institutet also found that ramping up the activity level to ‘moderate’ or ‘vigorous’ had even greater results, even when the study subjects just got off the sofa to work out for a mere 10 minutes a day – a 38% reduced risk of death from cardiovascular disease in fact. Not bad, especially for those who struggle to find (or make) time to get the blood pumping.


Save the power bill, Bikram doesn’t need heat

Psychologically, the idea of sweating litres seems to appeal to a lot of people looking to increase their fitness and wellbeing. If you’re sweating that much you must surely be cleansing your body of all those nasty toxins, right?

Well, researchers from the US have found that middle-aged people who attended unheated Bikram yoga classes, three times a week for 12 weeks, enjoyed the same improvements to their vascular health as another group that participated in identical classes in a heated environment.

Study author Dr Stacy Hunter of the Department of Health and Human Performance at Texas State University commented that ‘the heated practice environment did not seem to play a role in eliciting improvements in vascular health with Bikram yoga.’
