A study analyzed step counts from 94,696 adults in the U.K., finding a link between lower daily steps and a higher risk of Parkinson’s disease. The study suggests low step counts might be an early sign of Parkinson's, rather than a cause. While wearable devices track movement, they cannot diagnose Parkinson's.
Key Facts
The study involved 94,696 people from the U.K. Biobank who used activity trackers.
It found that lower step counts were linked to a higher risk of being diagnosed with Parkinson’s disease.
407 participants were diagnosed with Parkinson's over a median follow-up of 7.9 years.
The risk was most noticeable close to the time of diagnosis, not years later.
The study suggests low physical activity might be a consequence of early Parkinson’s symptoms.
Demographic and lifestyle factors like age and sex were considered in the analysis.
The study's findings do not mean step counts can diagnose Parkinson's.
The U.K. Biobank data may not fully represent the entire population.

Researchers found that vibrating certain tendons before exercise can make physical activity feel less demanding. The study used devices on the Achilles and knee tendons during cycling sessions, leading participants to exert more effort without feeling that exercise was more challenging.
Key Facts
An international research team from Canada and France conducted the study.
They used vibration devices on participants' Achilles and knee tendons before exercise.
Participants cycled harder and produced more power during the tendon vibration sessions.
Despite exerting more, participants felt the workout was as easy as without vibration.
The study only tested this method during a short, three-minute cycling exercise.
Vibration changes how the brain perceives effort by affecting signals from muscles.
Understanding these signals could encourage more regular physical activity.
