Abstract The associations of the serum metabolome (SM) and cardiovascular autonomic modulation (CAM) are underexplored, especially when considering the connection with regular physical activity. Investigating these associations may help in understanding the systemic effects of regular physical activity. In this exploratory study, the associations between CAM and SM were explored and also compared in physically active and inactive groups.

Background/Objectives: This study examined the effects of 2-weeks betaine versus placebo supplementation (3 g/d) on 60-km cycling performance, gut permeability, and shifts in plasma metabolites.

You are already at the latest version Objectives: This study investigated the effects of 2-weeks ingestion of hemp fiber (high and low doses) versus placebo bars on gut permeability and plasma metabolite shifts during recovery from 2.25 h intensive cycling. Hemp hull powder is a rich source of two bioactive compounds, N-trans-caffeoyl tyramine (NCT) and N-trans-feruloyl tyramine (NFT), with potential gut health benefits. Methods: The study participants included 23 male and female cyclists.
