On stress production in whispered Finnish
1987
We have compared sentence stress production in normal phonation and whisper in two native speakers of Finnish using acoustical analysis, esophageal pressure measurements and electromyography. The average peak values of the fundamental frequency, intensity, esophageal pressure and the EMG recordings from the thyroarytenoid and cricothyroid muscles were measured and their intercorrelations were calculated. In normal speech the cricothyroid activity and the subglottal pressure showed a significant correlation with the peak values of the acoustical indicators of stress for both subjects. The thyroarytenoid muscle showed a statistically significant correlation with the fundamental frequency for …
GENETIC AND ENVIRONMENTAL VARIATION IN PERCEIVED EXERTION AND HEART RATE DURING BICYCLE ERGOMETER WORK
1977
The relative contributions of heredity and environment to the variance in heart rate (HR) and rating of perceived exertion (RPE) during the bicycle ergometer work were studied with 14 pairs of male (6 monozygous (MZ) and 8 dizygous (DZ)) and 22 pairs of female (8 MZ and 14 DZ) twins ranging in age from 11 to 20 years. The results showed for both sexes that no significant differences in the intrapair variances of HR and RPE could be observed between the MZ and DZ twin samples. Thus it was concluded that in contrast to several other parameters of the measurements of the physical work capacity HR and RPE are not influenced to any significant degree by the genetic factors.
