A Development of Casual Model of Factors Affecting Exercise behavior of Mathayom 1 students Chiangrai Educational Service Area Office 1

Abstract

The objectives of the research are to study the exercise behavior of Mathayom 1 students,
Chiangrai Educational Service Area Office 1, to develop a casual model of factors affecting
exercise behavior, to examine the consistency of the model with empirical data, and to
analyze direct and indirect influences of variables to exercise behavior using LISREL model.
The research population were 2,336 Mathayom 1 students, Chiangrai Educational Service Area
Office 1 in Academic year 2009. Stratified Random Sampling was employed in order tochoose the sample group of totally 400 people. The research instrument was a questionnaire
about exercise behavior. There were 7 internal variables and 14 external variables. The research
data were analyzed employing linear structural model (LISREL) analysis.
The research findings were as follows :
1. According to using the questionnaire with the girls, there were different frequencies
reported respectively exercise once a week in 1-2 days and they usually exercise in different
time do it in the evening. There were spent 16-30 minutes exercising. The levels of exercise
were different exercise until they felt tired. Most of them exercise with their friends in order
to healthy. They choose different activities do normal activities.
2. Analytical results of the casual model found that the model was valid and fir to
empirical data. The model indicated that the chi-square (X2), it was stated that the chi-square
was not significantly different from those averaging the zero. The Goodness of Fit Index (GFI)
of 1.00, the Root Mean Squared Residual (RMR) of 0.00, RMSEA not over 0.05, Standardized
Residual not over 2.00, and the dammer of Q-Plot with it diagonal line were not rejected. For
these result the models related to empirical data. The variable of models in level .05 and .01,
The coefficient or R Square. The variable of exercise behavior of .36, This models indicated
the variation of exercise behavior get 36 percentage.
3. The highest influence in the model was the total of influence variable about exercise
which influences the supporting variable. The other influences were found respectively as the
following; the knowledge variable which influences the cognitive variable, and the least
influence variable was the individual variable which influences the supporting variable.
The highest direct influence in the model was the direct influence from the influence
variable which influences the supporting variable of exercising. The others were found
respectively as follows; the attitude variable which influences the cognitive variable, the
knowledge variable which influences the cognitive variable, and the least direct influence
variable was individual variable which influences the supporting variable.
The highest indirect influence in the model was the indirect influence from the influence
variable of exercising which influences the behavior variable through the supporting variable.
The others were found respectively as follows; the indirect influence from the influence
variable which influences the cognitive variable through the supporting variable, and the least
indirect influence variable was the individual variable which influences the behavior variable
through the supporting variable.
