Influence of Wearing Compression Tights During Prolonged Exercise on Muscle Fatigue, Muscle Damage and Inflammatory Responses

Abstract

The purpose of the present study was to determine the influence of wearing compression garments （compression tights） with different pressure intensity on muscle function, metabolite and endocrine responses, muscle damage and inflammatory responses to 120 min run at moderate intensity. Eight healthy young men conducted four trials on different days, consisting of [1] trial with wearing compression garments of heavy pressure intensity （approximately 40 hPa, High），[2] trial with wearing compression garments of moderate pressure intensity （approximately 20 hPa, Middle），[3] trial with normal sport garments （pressure intensity was set below 10 hPa, CON）．Each trial was performed with randomized orders, and four weeks of rest period were provided between the trials. Exercise consisted of 120 min of running on treadmill at 60% of maximal oxygen uptake （V･O2max）．Time-courses of changes in power output for lower limb muscles （maximal jump height），heart rate, ratings of perceived exertion （RPE），metabolic and endocrine responses, muscle damage and inflammatory responses were evaluated.
