The purpose of this study was to help university soccer players relieve sports stress through leisure satisfaction by efficiently utilizing their leisure time by identifying differences in leisure satisfaction and sports stress according to the types of leisure activities. In order to clarify this, the convenience sampling method was used for university soccer players registered in the Korea Football Association in 2021. The survey was conducted from September 4th to September 19th of 2021, and a total of 311 copies were used for data analysis. The following results were derived. First, significant differences were found in psychological leisure satisfaction, educational leisure satisfaction, physiological leisure satisfaction, and environment leisure satisfaction. Second, there were no significant differences in all leisure satisfaction sub-factors. Third, it was found that relaxational leisure satisfaction and physical leisure satisfaction had a significant effect on dissatisfaction with soccer skills, and environment leisure satisfaction was found to have a significant effect on restrict private life. As a result of this study, it is necessary to develop leisure education and leisure activity programs for university soccer players.

The aim of this study was to analyze the relative importance of bone age and chronological age in physique according to gender and to identify the relative importance of bone age, chronological age, and physique in physical fitness and motor coordination according to gender in order to alleviate the imbalance between physique and physical fitness in children. A total of 666 children(346 males, 320 females) between the ages of 11-14 were enrolled as subjects, and the skeletal maturation, which is proven and used most often as indicators of biological maturation, were measured in order to calculate the bone age. The skeletal maturation were measured by taking hand-wrist radiographs of children and were calculated in order to reflect bone maturities of each part by calculating the bone age using the TW3 method, which determines skeletal maturation. The calculation method of chronological age was done by dividing 12 months into 10 points, giving scores ranging from 0 points in December to 0.91 points in January, starting with the month of the child"s birth. A stadiometer and InBody 270(Biospace, Korea) were used to measure 8 components in physique. Physical fitness were measured through a total of 4 components: muscular strength, flexibility, muscular endurance, cardiovascular endurance; and motor coordination were measured through a total of 3 components: balance, agility, power. The data processing was performed using SPSS 25.0 with descriptive statistics, stepwise regression, and it was considered significant at the level of P< 0.05. The results of this study may be summarized as follows. First, physique variables for both males and females aged 11-14 were found to be more significant predictors of bone age than chronological age. Second, for physical fitness in males, in the order of %fat, body water, waist-hip ratio, weight, fat-free mass, and chronological age were more significant predictor variables; and in females, in the order of %fat, fat-free mass, height, chronological age, weight, bone age, fat mass, and body water were more significant predictor variables. For bone age and chronological age in physical fitness, bone age in males and chronological age in females found to be the more representative variables respectively.

본 연구는 청소년들의 체격과 체력을 평가하는 데 있어 골연령이 더욱 효과적일 것이라는 점을 가정으로 진행하였으며, 본 연구의 목적은 청소년기의 학생들을 대상으로 골연령과 역연령을 통해 체격과 체력의 차이를 규명하여 청소년들의 체격, 체력의 균형적 발달과 학생들의 건강증진에 기여하는 데 있다. 연구 대상은 6세부터 16세까지의 총 1100명의 모집단 중 PAPS(학생건강체력평가)와 TW3 방법 연령 기준 에 따라 총 874명(남자 483명, 여자 391명)의 11세∼16세 청소년을 대상으로 하였으며, 생물학적 성숙지표를 나타내는 골격성숙도는 X-ray 촬영 후 TW3(Tanner-Whitehouse 3) 방법을 이용하여 평가하였고 역연령은 출생년월을 사용하였다. 체격은 신장계, InBody270(Biospace, Korea)을 이용하여 2개 항목을 측정하였고 체력측정은 총 7개 항목으로 근력, 평형성, 민첩성, 순발력, 유연성, 근지구력, 심폐지구력을 측정하였다. 자료처리 방법으로는 SPSS 25.0을 사용하여 독립표본 t-test를 실시하였고, p< .05 수준에서 유의한 것으로 간주하였다. 본 연구의 결과는 다음과 같다. 첫째, 골연령과 역연령을 이용한 체격의 비교에서 11세, 12세 남자는 키와 체중에서 유의한 차이가 나타났으며, 13세 남자는 체중에서 유의한 차이가 나타났다. 11세 여자는 체중과 신장, 12세 여자는 신장에서 유의한 차이가 나타났다. 둘째, 골연령과 역연령을 이용한 체력의 비교에서 11세 남자는 근력, 순발력, 유연성, 심폐지구력에서 유의한 차이가 나타났고 12세 남자는 근력, 순발력, 심폐지구력, 13세 남자는 유연성에서 유의한 차이가 나타났다. 11세 여자는 근력, 순발력, 유연성, 근지구력, 심폐지구력, 14세 여자는 유연성에서 유의한 차이가 나타났다. 이러한 결과로 본 연구에서는 급격한 골 성장이 이루어지는 시기에는 골연령을 기준으로 체격과 체력을 평가하는 것이 역연령 기준으로의 평가보다 정확하다는 결과를 도출하였다. This study was conducted on the assumption that bone age would be more effective when it comes to physique and physical fitness assessment for adolescents, and the purpose of this study was to identify the differences in physique and physical fitness for students in their adolescence through bone age and chronological age in order to contribute to the well-balanced physique and physical fitness development in adolescents and the health improvement in students. Total 874 adolescents(483 males, 391 females) aged 11∼16 were selected as subjects out of the total population of 1100 adolescents aged 6∼16 based on the PAPS(Physical Activity Promotion System) and age standards of the TW3 method; and skeletal maturation, which symbolize the indicators of biological maturation, were evaluated by using the TW3(Tanner-Whitehouse 3) method after hand-wrist radiographs, and birth date was used for chronological age. A stadiometer and InBody 270 (Biospace, Korea) were used to measure 2 components in physique. A total of 7 components in physical fitness, which included muscular strength, muscular endurance, flexibility, power, cardiovascular endurance, balance, agility, were measured as well. A independent samples t-test was conducted for data processing using SPSS 25.0, and the significance level was set at p< .05. The study results are as follows. First, bone age and chronological age used for physique comparison in males aged 11 and 12, height and weight showed significant difference; in males aged 13, weight showed signicant difference. Weight and height in females aged 11, and height in females aged 12 showed significant difference. Second, bone age and chronological age used for physical fitness comparison in males aged 11, muscular strength, power, flexibility, cardiovascular endurance showed significant difference; in males aged 12, muscular strength. power, cardiovascular endurance; in males aged 13, flexibility showed significant difference. Muscular strength, power, flexibility, muscular endurance, cardiovascular endurance in females aged 11, and flexibility in females aged 14 showed significant difference. As a result, this study concluded that in a period of rapid skeletal growth, evaluating physique and physical fitness based on bone age is more accurate than evaluating based on chronological age.

This study aims to evaluate physical fitness according to the bone age of youth, and ultimately provide basic data for balanced development of youth through physical fitness standard indicators according to the bone age. A total of 730 youth aged 11 to 13 years in bone age and 11 to 13 years in chronological age were selected as subjects; and after taking X-ray films to calculate the bone age, they were evaluated by using the TW3 method. A total of 2 components in physique, which were stature and weight, were measured using a stadiometer(Hanebio, Korea, 2021) and Inbody 270(Biospace, Korea, 2019). A total of 7 components in physical fitness were measured as well, which included muscular strength (Hand Grip Strength), balance (Bass Stick Test), agility (Plate Tapping), power (Standing Long Jump), flexibility (Sit&Reach), muscular endurance (Sit-Up), and cardiovascular endurance (Shuttle Run). Descriptive statistics and independent t-test were conducted for data processing using the SPSS PC/Program(Version 26.0), and it was considered significant at the level of p< .05. The results of this study may be summarized as follow. First, the result of comparing the bone age and the chronological age of 11 to 13 years old in physical fitness, males showed significant difference in muscular strength, power, muscular endurance, and cardiovasular endurance. In females, muscular strength, balance, agility, power, flexibility, muscular endurance, and cardiovascular endurance showed significant difference. Second, physical fitness standard indicators were presented for each gender and age (11-13 years old) of youth according to the bone age; and based on this, physical fitness standard indicators, which are basic data for physical fitness evaluation according to the bone age of youth, were presented.
