Cycling

Research summary

• Direct evidence specifically on cycling is comparatively limited: a systematic review reports associations between commuter cycling and lower all-cause and cancer mortality, and a long-running Swedish women's cohort found cycling-test fitness in midlife linked to lower dementia risk decades later.
• Several other studies referencing cycling in this dataset concern different contexts, such as spinal cord injury rehabilitation, general exercise and mental health, or unrelated clinical topics, and so provide limited direct support for cycling specifically.
• Given the small number of studies that isolate cycling as the exposure, confidence in cycling's distinct benefit (beyond general aerobic exercise) is moderate rather than strong, even though the available findings point in a consistently positive direction.
