NCT ID: NCT05214027 Phase: Status: COMPLETED Enrollment: 34 Completion: 2021-11-01

Summary
Vitamin D deficiency is considered a public health priority in the UK, with approximately 30-40% of the UK population being deemed vitamin D deficient during winter months. Current government strategies to improve vitamin D status amongst the UK population involve dietary supplementation, however, it has been shown that excess adiposity reduces the impact of dietary supplementation with vitamin D. One potential explanation for this observation is that vitamin D becomes sequestered in adipose tissue. We hypothesise that exercise may facilitate the mobilisation of vitamin D from adipose tissue and thus increase circulating vitamin D (25OHD) concentrations. Little is currently known as to whether a single bout of exercise affects vitamin D status, with a handful of studies demonstrating contradictory findings. This research will examine the effect of an acute bout of exercise (treadmill-based at 60% VO2 Max for 60 minutes) on vitamin D status (serum 25(OH)D) in healthy community-dwelling adults.
Primary Outcome
Serum vitamin D concentration
