Abstract

The results of analysis on the relevance of lower extremity factors on professional physical strength in snowboarders in the national team and professionals are as follows. For the relevance between lower extremity factors and anaerobic exercise capacity, length of the lower limbs showed the significant correlation in Mean power, Peak power, Fatigue Index and Total work. The maximal circumference of the thighs showed the significant correlation in Mean power, Peak power, Fatigue Index and Total work. The maximal circumference of the lower legs also showed significant correlation in Mean power, Peak power and Total work. For the relevance between lower extremity factors and isokinetic muscular strength, length of the lower limbs showed the significant correlation in PPFR, PPEL, PPER, APEL and APER. The maximal circumference of the thighs showed the significant correlation in PPER and APEL. The maximal circumference of the lower legs also showed the significant correlation in PPEL, PPER, APEL and APER. It was shown that lower extremity factors affected anaerobic exercise capacity and gave significant effects on Mean power (length of the lower limb, length of legs, maximal circumference of thighs), peak power (length of lower limb), Time to peak power (length of lower limb, thigh subcutaneous fat), Fatigue Index (length of lower limb), Peak power/kg (length of thighs, length of the lowers limb, length of leg), Mean power/kg (length of thighs, length of legs) and Total work (length of the lower limbs, length of legs, maximal circumference of thighs). It was shown that lower extremity factors affected isokinetic muscular strength and gave significant effects on PPER (length of the lower limbs), PPEL (length of lower limbs), APFR (maximal circumference of thighs), APEL (length of the lower limbs) and APER (length of the lower limbs). This study could present physical and physiological standards upon rearing prominent players and selecting good players for elite snowboard players based on the results. It also can provide coaches with experimental data necessary for scientific training program, improvement on performance and ideal body composition.
