Thts research aims to study: (1) the effect of circuit training and rest between 2-minutes and 3-minutes circuit on basketball athletes' aerobic endurance, (2) the effect of gender on basketball athletes' aerobic endurance, and (3) the interaction between circuit training (2-minutes and 3-minutes rest) and gender (male and female) on basketball athletes' aerobic endurance. This research applied an experiment method with a 2×2 factorial design. There were differences between the 2-minutes rest and 3-minutes rest on male and female aerobic groups. In overall, there is an increased aerobic ability with circuit training and 2-minutes and 3-minutes rest between sets in either male or female group. However, 3minutes rest causes the aerobic ability to increase more.

This study aims to find out and explain the picture of gross motor skills in early childhood, cognitive abilities of early childhood and the relationship of gross motor abilities with cognitive abilities in early childhood. The research method used in this study is the correlational method. The sample in this study was 16 grade B students of Tunas Cempaka Kindergarten who had an age of 5-6 years. The data collection instruments in this study used TGMD-2 for gross motor ability and observation sheets for cognitive abilities. The conclusion of the data analysis results is that gross motor ability is in the average category, cognitive ability is in the category of developing according to expectations (BSH) and positively there is a relationship between gross motor ability and cognitive ability in early childhood.

This study aims to determine the results of the development of Emotional Intelligence (Emotional Intelligence) on school sports learning activities. The research method used is development research from Borg and Gall (2017) which has been varied, namely (1) conducting preliminary studies, (2) model development plans, (3) initial model development, (4) revision of validation results (5) small group field trials, (6) revision of test results (final product). The instrument used in this study used a questionnaire to measure Emotional Intelligence (emotional intelligence) made by Goleman (2016), which was then adapted by researchers according to research needs. Data was collected using a questionnaire obtained from expert evaluation, small group trial of 20 junior high school students in the city of Cirebon. The data are the results of an assessment of product quality, suggestions for product improvement, and the results of filling out questionnaires by students. The data analysis technique used is descriptive percentage to reveal student assessments using a product developed with the help of the Statistical Package for Social Science (SPSS). Based on the results of the explanation above, it is hoped that the development of Emotional Intelligence (emotional intelligence) will help students in their daily lives, to be able to increase positive interactions with their environment, and be able to use emotions and emotional knowledge in improving thinking. Physical education teachers in junior high schools are expected to use products for developing Emotional Intelligence (emotional intelligence) for learning activities in schools.
