The Use Of Subjective Ratings Of Perceived Exertion (Rpe) To Estimate Fixed Blood Lactate Concentrations During Incremental Cycle Ergometer Exercise, Keith Robert Scotson

Theses : Honours

Prescription of exercise intensity based on blood lactate concentration has become widely accepted in recent years. The methods used to directly measure blood lactate concentration however, can be costly, time consuming and potentially hazardous to both subject and tester. Recent studies indicate that a strong relationship exists between subjective feelings of strain experienced during exercise and changes in the appearance of blood lactate. This raises the possibility that subjective ratings of perceived exertion (RPE) can be used to simply and effectively estimate and monitor appropriate exercise intensity based on blood lactate concentration. In order to test this theory two groups …

Frequency Of Attainment Of Plateau In Maximal Oxygen Consumption In Differentially Trained Athletes, Jeffrey Michael Seda

Masters Theses

A plateau in oxygen consumption during exercise testing has been considered a requisite indicator of achievement of true maximal oxygen consumption. The wide range of reported percentages of subjects revealing a plateau (7 to 80 percent) indicates that closer analysis of factors that may influence plateau attainment is necessary. This study examined the frequency of plateau attainment in two groups of differentially trained subjects. One group (TR) of 12 males (ages 18-36) were trained runners and the other group (WL) of 12 males (ages 18-31) consisted of trained weight lifters. The subjects participated in a series of maximal exercise tests …
