Effects of Lower-Limb Compression on Changes in Blood or Plasma Volume, and Cardiovascular Responses
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.8 Vol.8】
To investigate the effects of lower-limb compression (LLC) on (1) changes in blood or plasma volume, and cardiovascular responses, and (2) perceived sense of compression, six healthy subjects were tested. The LLC at 40mmHg in supine posture resulted in an significant increase of 3.0 and 4.8% for blood and plasma volumes, and an significant decrease of 10 bpm for heart rate, respectively. Red cell mass was unaffected by LLC. Resumption of blood or plasma volume and heart rate were much faster with compression than that without it after exercise at 50% VO₂max for 10 min. Subjects perceived the LLC at 40mmHg slightly tight.
These results suggest that LLC of the slightly tight degree is effective to prevent the hydrostatic force on body fluid shift and cardiovascular response.
