본 연구는 국가대표 스노보드선수들과 프로선수들의 하지형태요인과 전문체력에 관련성을 분석하였다. 하지형태요인과 무산소성 운동능력의 관련성 중 하퇴장은 Mean power, Peak power, Fatigue Index, Total work에서 유의한 상관관계가 나타났으며, 대퇴최대둘레는 Mean power, Peak power, Fatigue Index, Total work에서 유의한 상관관계가 나타났다. 하퇴최대둘레에서도 Mean power, Peak power, Total work에서 유의한 상관관계가 나타났다. 하지형태요인과 등속성 근파워의 관련성 중 하퇴장은 PPFR, PPEL, PPER, APEL, APER에서 유의한 상관관계가 나타났으며, 대퇴최대둘레에서는 PPER, APEL에서 유의한 상관관계가 나타났고, 하퇴최대둘레에서도 PPEL, PPER, APEL, APER에서 유의한 상관관계가 나타났다. 하지형태요인이 무산소성 운동능력에 영향을 주는 요인으로 Mean power(하퇴장, 하지장, 대퇴최대둘레), Peak power(하퇴장), Time to peak power(하퇴장, 대퇴피하지방), Fatigue Index(하퇴장), Peak power/kg(대퇴장, 하퇴장, 하지장), Mean power/kg(대퇴장, 하지장), Total work(하퇴장, 하지장, 대퇴최대둘레)에 유의하게 영향을 미치는 것으로 나타났다. 하지형태요인이 등속성 근파워에 영향을 주는 요인으로 PPER(하퇴장), PPEL(하퇴장), APFR(대퇴최대둘레), APEL(하퇴장), APER(하퇴장)에 유의하게 영향을 미치는 것으로 나타났다. 본 연구의 결과를 바탕으로 엘리트 스노보드선수들의 꿈나무 양성 및 우수 선수 선발 시 신체적, 생리적, 체력적 기준치를 제시할 수 있을 것이며, 일선 지도자들에게 과학적인 훈련 프로그램을 구성하여 경기력 향상과 이상적인 신체조성에 필요한 실험적 자료를 제공할 수 있을 것이다.
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.
