And Now for some news ….
Activity Aging and Function in Older Adults
Despite extensive research, the relationship between age and physiological function remains poorly characterized and there are currently no reliable markers of human ageing.
The authors of recent study published in The Journal of Physiology, have studied a cohort of highly and homogeneously active older male and female cyclists aged 55–79 years who it is proposed represent a model for the study of human ageing free from the majority of confounding factors, especially inactivity.
The aim of the study was to identify physiological markers of ageing by assessing the relationship between function and age across a wide range of indices.
The results of this cross-sectional study suggest that even when many confounding variables are removed the relationship between function and healthy ageing is complex and likely to be highly individualistic and that physical activity levels must be taken into account in ageing studies.
The Authors of the study plan to retest their volunteers in five and 10 years, which will provide better information about the ongoing effects of exercise on aging.
But even in advance of those results, said Dr. Harridge, himself almost 50 and an avid cyclist, this study shows that “being physically active makes your body function on the inside more like a young person’s.”

Athletic Activity and Disc Degeneration
Athletic activity did not put adolescents at an increased risk of developing disc degeneration or disc herniation, according to a presentation at a recent Spine Conference.
This was the finding of results presented of a retrospective, randomized, blinded review at the Philadelphia Spine Research Symposium. Schroeder and colleagues reviewed the medical records of adolescent patients from a single institution between 2004 and 2012 in an attempt to discover whether intense athletic participation had an effect on structural lumbar abnormalities.
The patients were divided into two groups, athletes and non-athletes, with athletes defined as individuals who participated in sports 5 days per week, 20 hours per week or who were on a varsity team. The study included 66 athletes and 48 non-athletes.
Study results showed the overall prevalence of lumbar spine pathology in symptomatic patients was about 55%, according to the lead author.
“However, the rate of spondylosis was significant higher — 32% in the athletes, compared with 2% in the non-athletes. This led to a statistically significant increase in the risk of any lumbar pathology in the athletes compared with the non-athletes.
