The purpose of this study is to examine the balance and attention characteristic of dance exercise. 200 university students with a mean age of 20.63+1.59, who studied at the Faculty of Sport Sciences at Muğla Sitkı Koçman University in the 2016-2017 academic year participated in the study. University students participating in the study were taught 3 hours of Latin dance (salsa, bachata) once a week for 12 weeks. The "d2 attention test", which validity and reliability was performed in Turkish by Çağlar and Koruç [1], developed by Brickenkamp [2], was used to determine students' attention attributes related to dance exercise. Data analysis, frequency analysis, Impulsive statistics. Kolmokorov-Smirnov test, t-test, Mann-Whitney U test were used. As a result, there was no significant difference between the experimental and control groups of the body weight pretest and posttest values of the students participating in the research. A significant difference was found between the experimental and control groups in the balance posttest value. A positive change was determined in the attention, error, and concentration post-test values of the students who participated in the dance study. It has been determined that dance work positively affects balance and attentiveness.

The purpose of this study is to explore the influence of reliability and brand image on purchase intention of sports brands endorsed by entertainers. A questionnaire survey is conducted in this study, and the students from Hsin Sheng Junior College of Medical Care and Management are taken as research objects. A total of 300 questionnaires are sent out; after the deduction of 5 invalid questionnaires, a total of 295 valid questionnaires are collected. In this study, SPSS20.0 for Window Chinese package statistical software is used as the analysis tool. After the verification of descriptive statistics, reliability analysis, independent sample t test, Pearson product difference correlation analysis, and regression analysis, the results obtained are as follows: The reliability of entertainer endorsement has a significant impact on purchase intention, in which the influence of reliable image is greater than the influence of the attractiveness on purchase intention; Brand image has a significant influence on purchase intention, in which the effect of functionality in brand image is greater than the effect of symbolism in brand image on purchase intention; The reliability, brand image, and purchase intention of entertainer endorsement are significantly correlated. According to the results of this study, it is suggested that the selection of endorsers for sports brand companies must be consistent with the positive image of sports brand and have the popular impression, so as to attract consumers’ recognition and expectation of products and provide references for relevant manufacturers.

Regular exercise is highly effective in cardiovascular health improvement. Professional athletes have always been regarded as exemplars of good health and have also attracted scientific curiosity on account of the strength and endurance that characterize their lifestyle. Over a period of time in athletes, cardiac adaptations to sport activities occur. The normal electrocardiographic (ECG) presentation of the heart is changed and abnormal pattern becomes present. Some of these abnormal ECG changes are suggested to be maladaptations that are risk factors for sudden cardiac death. Does the abnormal ECG pattern have anything to do with the training age of the athletes? The aim of this study is to determine the relationship between electrocardiographic abnormalities and training age of athletes in Port Harcourt, Nigeria. A cross sectional descriptive study was carried out on a total of 170 athletes consisting of 63males and 107 females (16-35years of age). Their training ages were documented and the athletes were grouped into 3: Group 1 are athletes that have been training for 1-5years; group 2 : 6-10years and group 3 from 10 years and above. Anthropometric measurements and heart rates were determined. Physical examination was conducted to exclude the presence of associated co-morbidities. Electrocardiographic parameters were determined using a standard resting 12-lead electrocardiogram. Maladaptive ECG changes were determined using the Seattle criteria. Results showed that the training ages of athletes negatively correlated significantly with heart rate(R=-0.24; P=0.001) and T-axis (R=-0.24; P=0.01). Also training age positively correlated significantly with QRS- Interval (R=0.16; 0.03) and QT- Interval (R= 0.22; 0.001). Athletes in group 3 (training age > 10years) recorded a significantly higher percentage of the occurrence of repolarization abnormality (ꭕ2 =5.50; p= 0.04). In addition, being a female and increased training age, are the significant predictors of the occurrence of a maladaptation. (Odd ratio=4.38; p=0.003 and odd ratio = 1.14; p=0.03 respectively). The abnormal electrocardiographic changes found in this study may be due to some physiological maladaptation resulting from prolonged training age and possibly sex variation. These maladaptations are suggestive of risk factors for possible sudden cardiac death.
