The effect of direct instruction model in physical education towards students’ adversity quotient (AQ). The purpose of this study is to determine the significance of the effect of direct instruction in physical education and problem-solving skills to survive the problems that faced students (Adversity Quotient). The applied method is experiment one group pretest posttest design. The procedures of this research are observation, interview, treatment program preparation, analysis and conclusion. The research findings are achieved experiment group with direct instruction model giving significant influence towards students’ adversity quotient level with score on (sig.),000 < α=0,005. Based on the data, it can be concluded that the direct instructional model giving significant affect towards the level of students’ adversity quotient.

Physical activity positively impacts cognitive function and can help avoid cognitive impairment. The study aimed to investigate the association between cognitive function and physical activity in junior high school students in Bandung. This research is quantitative research with a correlation analytic design. The instrument used in this study is a questionnaire. The sampling technique used is a random sample, the sample is 1870 respondents. The questionnaire used in this study is a closed questionnaire, which is a questionnaire whose answers have been provided so that respondents only need to choose. The study found that half of the respondents with less activity experienced less cognitive function (71,8%). Almost half of the respondents had a physical activity with good cognitive function (21.6%), and a small proportion of physical activity experienced quite a number of cognitive functions (8.6%). There is a relationship between physical activity and function cognitive in students. The results of this study are expected to be taken into consideration for further research by examining other factors related to cognitive function and other factors related to physical activity, such as gender, socioeconomic, and family factors.

Lung vital capacity is the status of physiological conditions associated with the ability to treat respiration together with the increasing of physical fitness, so lung vital capacity is a process involving the mechanism of the heart and blood vessels and blood which aims to provide O2 to cells in the body and transport CO2 out of body. The purpose of this study is to determine the correlation between lung vital capacity and the physical fitness level of Pendor Football Athletes from Universitas Riau. The collecting of data in this study is data from lung vital capacity tests and physical fitness with a sample of 20 athletes. Analysis of the data that used to process data is Product Moment correlation. For determining the significance of data, it uses formulation of t distribution. The results that obtained from lung vital capacity have a significant correlation with the level of physical fitness, this is indicated by the results obtained by r count (0622) > r table (α = 0.05) = 0.456. Meanwhile, t distribution test is obtained the result of t count (3,369) > t  table (1,734). So H0 is refused  and Ha is accepted. Thus it can be concluded that there is a significant correlation between the lung vital capacity (x) and the level of physical fitness (y).
