Abstract
The purpose of the study was to investigate the rate of lactate removal from the blood of trained distance runn ers , during recovery from maximal intermittent exercise • • Five well trained male subjects (mean vo2 max of 69.79 ml/kg/min) were selected for the study. Four of the subjects were members of the 1975 Intercollegiate Cross Country team and one was a member of the 1 975 Intercollegiate Soccer team at Eastern Illinois University. Each subject received an orientation to the treadmill and a maximum oxygen consumption test prior to the actual test procedure . The test procedure consisted of three separate warm-down periods following maximal intermittent exercise . The three warm down periods were JO minutes in duration and consisted of sitting , walking at four miles per hour , and jogging at eight miles per hour . Blood samples were drawn from an arm vein of the subject five , 1 5 , and JO minutes following exercise and were analyzed for lactate . A Friedman two-way analysis of variance by ranks was used to test whether there were any significant dif ferences between the blood lactate concentrations of the different warm-down procedures . It was concluded that the JO minute , eight mile per hour jog was a better warm-down procedure than the JO minute , four mile per hour walk for removal of lactate from the blood of trained distance runners. Sitting for JO minutes was the least effective method .
A jog at eight miles per hour is a better warm-down procedure for removing lactate from the blood of trained distance runners than a four mile walk, while sitting for jo minutes is the least effective.
