Exercise-induced fluid shifts are distinct to exercise mode and intensity: a comparison of blood flow-restricted and free-flow resistance exercise

Using muscle functional MRI (mfMRI), this study was able to differentiate the acute physiological responses following three established hypertrophic resistance exercise strategies. Low-load protocols performed failure, with or without blood flow restriction, resulted in larger changes R 2 (i.e. greater T -shifts) a slow rate of return baseline indicative myocellular fluid shifts. These data were cross evaluated interleaved measures macrovascular flow, water diffusion, sectional area macroscopic swelling), and intracellular fraction measured using MRI.
