| Abstract:
The relation of physiological and psychological effect of horticultural activity based on the principal components analysis. Physiological and psychological measurements of 36 university students were taken after doing horticultural activities. Physiological measurements were made of caloric energy expenditure by using electro telemetric system. Psychological measurements were taken by demographic questionnaire and ZIPERS test. Correlation coefficient and principal component analysis were adapted to define the reciprocally physiological and psychological effect of horticultural activity. The results from analyzing after principal components analysis, we could get seven principal components from the result depend on the eigenvalues. These seven principal components can describe 81.1% of change of all variance of valuables. On the first principal component, the positive affective states of ZIPERS (Q3, Q5, Q6, Q7, and Q9) have positive factor value. While, preference of exercise, favorite food and stress condition have negative factor value. Therefore, the first principal component represented the positive affective state after doing horticultural activity. On the second principal component, the negative affective state (Q1, Q2, Q4, and Q8) and exercise preference have positive factor value. While positive affective state (Q5, Q6, Q7, and Q9), caloric energy expenditure, favorite food and stress condition have negative factor value. Therefore, the second principal component represented negative affective state and negative feelings of physical condition. On this study, the results indicate that physiological and psychological measurements have reciprocal effect and affect each other. | |
