Increased physical activity not linked to ALS risk

25.01.2005


There is no association between increased physical activity and the risk of developing ALS, according to a new study published in the January 25 issue of Neurology, the scientific journal of the American Academy of Neurology. The new study contradicts previous studies linking risk of developing ALS to excessive physical activity and a slim physique.



ALS (amyotrophic lateral sclerosis), sometimes called "Lou Gehrig’s Disease" after the famous baseball player whose career was cut short by the disease, is a progressive disease of the nervous system, often causing death in three to five years.

For the large case-controlled study, researchers compared occupational and leisure time physical activities of 219 ALS patients and 254 controls. All study participants were measured on early, late, and total physical activity: until the age of 25; until one year before the onset of the disease; and the last 10 years before the onset of the disease.


"The results showed that there was no significant association between risk of developing ALS and increased occupational or leisure time physical activity," said study co-author L.H. van den Berg, MD, PhD, researcher at the Rudolf Magnus Institute of Neuroscience, Utrecht, The Netherlands. "However, we did find evidence to suggest that in those at risk of developing ALS for reasons other than physical activity, a higher level of activity could accelerate the onset of the disease; although other exposures during physical activity might also explain the association with early onset ALS."

The study revealed that in patients with higher leisure time physical activities before the age of 25, onset of the disease was seven years earlier. Higher leisure time physical activities during the 10 years before onset resulted in earlier onset of the disease by three years.

While previous studies have investigated the link between increased physical activity and the risk of developing ALS, no previous study has investigated the relationship between high physical activity and the duration of ALS or the age of onset.

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
