The purpose of this study is to construct a knowledge structure for the application of physical education in ecological marine sports. As specific exercises, a volleyball game (beach volleyball) and open water swimming were set, and a knowledge structure analysis framework was used for the study. Expert consultation was conducted to secure the validity of the study. The study results are as follows. First, a knowledge structure based on the 2022 revised physical education curriculum was prepared. Second, the basis for the application of physical education classes for ecological marine sports was prepared. Third, learning contents in the knowledge·understanding domain, process·functional domain, and value·attitude domain of beach volleyball were proposed. Fourth, learning contents of knowledge·understanding domain, process·function domain, and value·attitude domain of sea swimming were proposed. This study is meaningful in that it prepared in advance for the realization of the 2022 revised physical education curriculum to be introduced in the future.

This study investigated the purchase status, wearing status, purchase satisfaction, selection criteria, and improvement marin leports wear for subjects who enjoy marine leisure sports in the southwestern region of Jeollanam-do, and examines the correlation between age and body type and the correlation between variables. SPSS Ver. 26.0 program was used for analysis. In the correlation between the motivation for participation and the selection criteria, when participating to increase physical strength, it was selected based on the fit. When participating for leisure or hobbies, they were selected based on design and color. The relationship between the selection criteria and purchase satisfaction was not satisfied in terms of price when they were selected based on activity or utilization of other uses. As for the selection criteria according to the body type, clothing was selected based on price and fashion for large triangles and squares, and elasticity for inverted triangles. As for the preferred color by age, only those in their 40s preferred blue and other age groups preferred achromatic color. In future studies, it is thought that a study on the preference of each marine leisure sports item should be conducted.

Purpose: The aim of this study was to investigate the effects of different types of unstable loads on core and lower limb muscle activity during squatting. Methods: Nineteen subjects (all females) with resistance experience but no unstable resistance experience participated in the study. Subjects performed squats under three load conditions, and core and lower limb muscle activity was measured during eccentric and concentric contractions. Results: During the eccentric contraction, core and hip flexor activity was significantly higher with the aqua bag than with the barbell or resistance band, and for the quadriceps, the resistance band was significantly higher than the barbell. During the concentric contraction phase, core and hamstring muscle activity was significantly higher with the aqua bag than with the barbell and elastic band (p < 0.05). Conclusion: Squats with an aqua bag increase core and biceps brachii activation and can be recommended as a training method to improve trunk stability.

The purpose of this study was to investigate the consumer buying behavior on rash guard for marine sports. Survey data collected from 105 men in activities of marin sports were analyzed by descriptive statistics, chi-square test, correlation analysis. The results of this study were as follows. First, the age showed a positive correlation in activity carrier. The 64.8% of subject enjoyed primarily the marin windsurfing sport. Second, the buying place was different according to the age group and activity carrier. Domestic brands were lower preference than foreign brands. And there was difference between the domestic and foreign brands in design and wearable sense. The coordinates of rash guard were to pursuit the overall beauty, considering the functional and physical protection. Therefore, it is necessary for the domestic brands to develop the products competing with the foreign brands.

The purpose of this study was to analyze the relationships among sport enjoyment, participation satisfaction, and participation adherence intention of water leisure sports participants in Busan. The study conducted a research survey through purposive sampling method after selecting 3 water leisure sports center in Busan. 360 questionnaires distributed and 352 were selected as final valid sample by removing 8 questionnaires that have insufficient answers. Hypothesis test on collected data was conducted by using SPSS 20.0 and AMOS 19.0 programs. The results were as followings. First, sport enjoyment had a significant effect on participation satisfaction. Second, sport enjoyment had effect on participation adherence intention. Third, participation satisfaction had effect on participation adherence intention. Fourth, sport enjoyment had directly positive effect on participation adherence intention. In addition, it had effect on participation adherence intention as the partial mediation of the participation satisfaction.

The purpose of this study was to verify the influences of sport enjoyment factors on recreation specialization of water sports participants. The study conducted a research survey through purposive sampling method after selecting 4 water sports center in Busan. 260 questionnaires distributed and 246 were selected as final valid sample by removing 14 questionnaires that have insufficient answers. Then data were analyzed through exploratory factor analysis, reliability analysis, correlation analysis, and multiple regression analysis using SPSS Window ver. 20.0. The results were as followings.

The purpose of this study was to clarify the casual effects among participants'curiosity, the perceived exertion and the exercise emotion on the exercise adherence behavior in marine leisure sports. The subjects for the study was 491 students who registered for the curriculum on marine leisure sports(SCUBA diving, Windsurfing, Yacht). They answered to 4 kinds of questionnaires. The descriptive analysis and the reliability analysis were accomplished through SPSS 18.0. The correlation analysis and the confirmatory factor analysis were conducted for verifying the validity of the research model with AMOS 18.0. The verification for the structure equation modeling was conducted to investigate the casual relationship among factors. The results was as follows. First, there was the causality between the participants'curiosity on the marine leisure sports and the exercise emotion, the emotion and the exercise adherence behavior, the curiosity and the behavior. Also, the exercise emotion was the partial mediating variable of the causality between the curiosity and the exercise adherence behavior. Seconds, when the exercise intensity was heavy, the rate of the positive emotion was low and the opposite was high. When the exercise intensity was heavy, the probability, predisposing and reinforcing were low. A strong will for doing exercise showed in case the exercise emotion was positive with high probability, predisposing and reinforcing. The exercise emotion was the partial mediating variable of the causality between the perceived exertion and the exercise adherence behavior.

Objective: The purpose of this was to find out the muscle activity of the quadriceps femoris by gender when sitting on a chair while performing stairs gait (US; Up-stairs, DS; Down-stairs). Method: 13 male subjects (age: 22.00 ± 1.68 yrs, height: 174.85 ± 6.10 cm, weight: 68.15 ± 9.83 kg) and 15 female subjects (age: 21.17 ± 1.58 yrs, height: 168.20 ± 5.55 cm, weight: 55.73 ± 6.94 kg) participated in this study. The study used wireless three channel EMG. Results: In this study, there was no gender difference in quadriceps femoris activity during the US and DS periods, and there was no significant difference between the male group before and after postural maintenance during the US and DS periods. The quadriceps muscle of the female group also did not show a significant difference before and after US sitting. However, the vastus medialis muscle activity during DS in the female group was significantly lower after application than before application of maintaining a sitting posture (p<.05). There was no interaction effect between the 15-minute sitting position application and gender. Conclusion: Our results demonstrate that sitting in a chair affects the transient functioning of the quadriceps muscle in women. Therefore, emphasize the need for active rest when sitting in a chair for long periods of time.
