Constructual and Concurrent Validity of analog perceived exertion scale (OMNI) during sub-maximal and exuastive activity in deaf adolescents

Theconditions of a safe exercise program, depends on the physiological and motivational abilities of individuals. Furthermore, the estimated prominent component of the intensity of physical activity is very important, especially for deaf children.
24 deaf adolescences aged 12 to 18 years, with a hearing impairment greater than 80 DB, and a mean BMI of (19.9 ± 3.5 Kg/m2), voluntarily performed the aerobic maximal protocol along with analysis of respiratory gases with the verbal BORG10 and visual OMNI perceived exertion scales.
Construct validity showed a significant correlation between BORG10 and OMNI scales during submaximal ergometery (R=0.73, P=0.002), and high significant correlation also found during an exhaustive exercise (R=0.91, P=0.001). on the other hand, moderate correlation was observed for accectable concurrent validity with respet to relationship among two the psychosomatic scales and physiological indexes (HRR, VO2, VE) during the submaximal ergometery.
Because, to communicate and interaction problems in deaf children with the social environment especially during a physical activity, both analog and numerical Perceived Exertion scales have optimization construct validity to adjust the various daily physical tasks. Visual Perceived Exertion Scale is also more efficient during an exhaustive and relatively maximal aerobic ergometery and can be used during attending targeted deaf children to develop physical activity during leisure time or sports events planning for coaches.
