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.
Purpose The purpose of this study was to explore the optimal model for winning medal on vault event of men's gymnastics. Specifically, decision tree analysis was used to explore, first, for the optimal conditions for qualifying top 8th player that have high possibility into final round, and second, for the optimal model for obtaining the medal of the vault event. Methods Data were collected for five official competitions (Olympics, Asian games, and International championship, etc.) organized by the Federation of International Gymnastics (FIG) from 2013 to 2016. In this study, the data of 626 vault players were collected. Also all of these players performed 921 vault skills for qualifying round or final round. Five predictor variables for estimating for qualifying into the final round and for obtaining the medal of the vault event were selected; nationality, difficulty score, acting score, additional penalty score, final score. Results The results is as follows. Overall, it was confirmed that the optimal model for entering into the final round was the difficulty score of vault event. The optimal model for entering into the final round estimates 81.2% when condition would be the 5.6 or higher of difficulty score and 8.6 or higher of the acting score. The optimal model for winning medals was 86.7%, which means that when condition would be the 6.0 or higher of difficulty score and no additional penalty score. Conclusions This models can be used as a basic data for establishing a strategy for medal acquisition of vault event of gymnastics.
Purpose The purpose of this study was (1) to analyze judges’ evaluation on rhythmic gymnastics performance by applying generalizability theory and (2) to suggest recommendations to improve judges' rating. Methods Data were 34 players’ scores from Senior Part at 29th KGA President’s Cup National Rhythmic Gymnastics Championship in Korea. Difficulty and execution scores in ball, clubs, hoop and ribbon event were analyzed. Analysis models containing components of area and reputation rank were designed and multivariate generalizability theory were used for analysis. Results The G-study results showed (1) that the error source about players has more significant impact to evaluation than other error sources in analysis model containing components of only player and judge, (2) that the error source about players has more significant impact to evaluation than other error sources in analysis model adding components of area, but the error source about area has more significant impact to evaluation of clubs event than other error sources, (3) that the error source about players has more significant impact to evaluation than other error sources in analysis model adding components of reputation rank, but the error source about reputation rank has more significant impact to evaluation of hoop event than other error sources in analysis model adding components of area. The D-study results showed generalizability coefficient was stable in analysis model without components of area and reputation rank, but generalizability coefficient in analysis model containing components of area and reputation rank not stable in some event. Conclusion Recommendations for improving judging were discussed.
PURPOSE This study presents policy implications drawn from a factual survey on the sports services industry in Korea, aiming to understand its current status and provide systematic support for high growth sectors. METHODS The research involved 600 companies across 18 sports service industry sectors, with growth potential assessed using standardized Compound Annual Growth Rate (CAGR) scores based on indicators such as the number of businesses, employees, sales, business productivity, and labor productivity. RESULTS Results revealed that high-growth sectors were more prominent in the Incheon/Gyeonggi regions, while general sectors showed higher proportions in the Seoul area. Satisfaction with government support programs was above average in high-growth sectors, contrasting with lower satisfaction in general sectors, depending on the criteria. Both high-growth and general sectors faced difficulty securing liquid assets, expressing expectations for government financial support, such as expanded loans. CONCLUSIONS Therefore, a policy for achieving regional balance for sports service industries concentrated in the metropolitan area and differentiation in regional sports service industries is necessary. Through a paradigm shift in business support, the competitiveness of the sports services industry can be enhanced, and comprehensive policies for the domestic sports service industry must be formulated.
