본 연구는 기능적 움직임 검사(Functional Movement Screen: FMS)의 결과를 통해 U-19 축구선수 집단에 적용된 FMS 측정항목들의 적합성과 난이도를 분석하여 U-19 축구선수들의 기능적 움직임 특성 및 능력을 파악하고자 하였다. 파주 NFC U-19 축구 국가대표팀 선수들 30명(19.3±0.66세)의 FMS 7개 항목(Deep Squat: DS, Hurdle Step: HS, In-line Lunge: IL, Shoulder Mobility: SM, Active Straight Leg Raise: ASLR, Trunk Stability Push-Up: TSPU & Rotary Stability: RS)을 측정하였다. 그 결과를 바탕으로 Rasch 모형을 사용하여 선수들에 대한 측정항목의 적합성(goodness-of-fit)과 난이도(item difficulty)를 분석하였다. FMS측정 결과, 총 점수 평균은 10.02±1.79점이였으며, HS, SM, TSPU를 제외한 DS, RS, IL, ASLR가 적합한 측정항목으로 나타났다(0.5< x <1.5). 또한, 적합한 측정항목인 DS, IL, ASLR, RS의 난이도는 2.08, .26, -3.16, .83(logit)으로 나타났으며, 순서대로 난이도가 높은 것으로 밝혀졌다. 따라서 본 연구는 U-19 축구선수들의 기능적 움직임의 수준이 성인 선수들 보다 낮으며, FMS 측정항목들이 종목의 특성과 선수들의 연령에 따라 다른 결과를 나타낼 수 있음을 제시하고 있다. The primary purpose of the study was to identify the characteristics of Korean national youth soccer players’ functional movements. The secondary purpose was to examine whether certain tests of Functional Movement Screen (FMS) meaningfully achieve goodness-of-fit for the soccer-specific movements. Korean national youth soccer players (30 male players, 18.37 ± 0.67 yrs, 178.7±7.09 cm, 70.2±6.46 kg), performed FMS tests [deep squat (DS), hurdle step (HS), in-line lunge (IL), shoulder mobility (SM), active straight leg raise (ASLR), trunk stability push-up (TSP), and rotary stability (RS)]. The mean (±SD) FMS composite score and each test score were calculated. Rasch analysis, which was used to determine the goodness-of-fit for the tests, was applied to examine the item difficulty of the FMS tests. The mean FMS composite score was 10.2± 1.79; the mean DS, HS, IL, SM, ASLR, TSP, and RS score were 1.13±0.35, 1.27±0.45, 1.4±0.56, 1.6±0.77, 2.07±0.69, 1.43±0.82, and 1.3±0.47 respectively. According to the results of Rasch analysis, 4 tests (DS, IL, ASLR, and RS) were shown to be within the acceptable range (infit & outfit > 0.5 ~ < 1.5). The other 3 tests (HS, SM, and TSP) were shown to be out of acceptable range. The additional analysis revealed the DS (logit = 2.08) as the most difficult test and ASLR (logit = -3.16) the least. The results of the study showed that the players’ FMS composite score was lower (< 14) than the cut-off points used by previous studies for different athletes. The further study is warranted to examine the relationships between the scores of the tests appeared to be soccer-specific in the present study and the level of performance variables.
