Continuous Training with Running Line Improve Cardiovascular Endurance in Visually Impaired Athletes Totally Blind Classification

This research purpose was testing the application of continuous training with running line to improve cardiovascular endurance in visually impaired athletes classified as totally blind. Three male 100 m sprint athletes with visual impairment classified as totally blind National Paralympic Committee Indonesia aged 20-30 years and weighing 65.33±4.93 kg. A one group pre-post design was used in this experimental study. Each participant underwent 3 weekly sessions for 6 weeks of continuous training with a running line. The data collected were cardiovascular endurance data using distance-based walk and run tests. The results showed an increase in the average VO2max in visually impaired athletes after continuous training with running line, which was initially 47.36±2.40 ml/kg/min then increased to 50.66±1.65 ml/kg/min. There is a difference in VO2max of blind athletes between before and after continuous training with running line, with a value of tcount = 6.305 > ttable = 4.304. So it is concluded that continuous training with running line seems to be effective in increasing cardiovascular endurance in visually impaired athletes classified as totally blind, which is indicated by an increase in VO2max value of 6.98%.
