Dermatoglyphics, maximal strength and ergometric performance in selected Chilean rowing athletes

Abstract

The aim of this study was to describe correlate the dermatoglyphic characteristics, high strength and performance ergometer rowing Chilean selected. The sample was comprised of 16 men aged 20.37 ± 3,68 years, 74.71 ± 5.07 kg. Of dough and 179.35 ± 4.15 cms. height summoned to the Chilean national Rowing to participate in the South American championship Rowing 2013. To identify the dermatoglyphic characteristics, the dermatoglyphic method Cummins and Midlo (1961) was used to measure maximal strength test 1 repetition maximum (1RM) squat and performance for the specific test ergometer test at the distance of 2,000 meters. The group presented a mean maximum force of 119.12 ± 22.07 kg raised in lower limbs and 89.62 ± 14.24 kg raised in upper limbs. In fingerprint designs, have an average of 14.4% for Arco, 68.8% in Presila, 16.9% whorl, 93 in SQTL and 10.6 in D10. Weather for 2000 mts. rowing ergometer was a mean of 388 ± 9.5 seconds. As for the correlational data, the group presented significant negative correlations between the ergometer time and raised in kilograms 1RM of -0.757 (upper extremities) and -0.637 (lower limbs), both with p <0.05. This study provides dermatoglyphic characteristics of rowers regarding national level, which could be useful in sports orientation, in addition to verifying the importance of maximum force on the ergometer and specific performance of competitive rowers.
