Long-Distance Skiers May Have “Motor Reserve” that Can Delay Onset of Parkinson’s Disease

Amsterdam, NL – To better understand the relationship between physical activity and Parkinson’s disease (PD) investigators in Sweden analyzed medical records of nearly 200,000 long-distance skiers who took part in the Vasaloppet cross-country ski race. They established that a physically active lifestyle is associated with close to a 30% reduced risk for PD, which might be explained by a motor reserve among the physically active, however, this dissipates as individuals age. Their results are published in the Journal of Parkinson’s Disease (JPD).
