In the last few decades, assessment of perceived exertion has become a routine practice in fitness and clinical settings to quantify subjective feelings of fatigue and exercise tolerance. The Borg-RPE scale and the OMNI-RPE scale have been used in various populations, i.e. children and adults. A recent investigation reported the validation of the OMNI-RPE scale in a sample of Spanish-speaking youth from the USA (9 to 12 yr. old).
PURPOSE: This study investigated the concurrent and construct validation of an Italian version of the OMNI-RPE scale.
METHODS: Eighty-two elderly (over 65 yrs.) men (n = 38) and women (n = 44) whose primary language was Italian were studied. The present study used a cross-sectional, perceptual estimation paradigm administered during a single, maximal graded exercise test on a cycle ergometer. Each participant undertook one orientation and one estimation trial. Ratings of perceived exertion for the overall body (OMNI-RPE and Borg-RPE) and physiological responses (oxygen uptake: VO2, heart rate: HR) were measured during each exercise stage.
RESULTS: For both female and male groups, the mean responses ranged: from 0.72 to 1.77 L·min·1 for VO2, from 87.4-137.4 beats·min·1 for HR, from 1.6 -7.9 for OMNI-RPE across the four exercise stages. When testing concurrent validity, regression analyses indicated that OMNI-RPE distributed as a positive linear function of both VO2 and HR (r = 0.69 and 0.73; r = 0.63 and 0.73 for men and women, respectively; P < 0.01). When testing construct validity the regression analyses indicated that OMNI-RPE scale distributed as a positive linear function of the Borg-RPE scale (r = 0.95 and 0.94; for men and women, respectively; P< 0.01).
CONCLUSION: Concurrent and construct evidence support the use of the Italian version of the OMNI Scale of Perceived Exertion to estimate effort during cycle ergometer exercise in Italian native speaking elderly men and women.
