Physical Fitness Correlated with the Health of Lower Secondary School Students at Demonstration Schools in Bangkok Metropolis Under the Jurisdiction of the Office of the Higher Education Commission

Abstract

In this thesis, the purpose of this research to study Health-related physical fitness and classify the Health-related physical fitness level of selected lower secondary school students at demonstration schools in Bangkok Metropolitan (BM) under the jurisdiction of the Office of the Higher Education Commission (OHEC). The research population consisted of 4,677 lower secondary school students at five demonstration schools in BM, 2,362 males, and 2,315 females. According to the estimation table, the sample size of Krejciey and Morgan, with a population of 5,000 people, yielding 357 samples, but in this study, the researchers used 900 samples of the 450 male students and 450 female students. the research instruments is a test and benchmark for Health-Related Physical Fitness Test for Thai children aged 7-18 years office of Health promotion Fund (2006). Data analysis was conducted using the determination of body mass index (BMI) and percentages involving subcutaneous fat, sixty-second sit-ups, thirty-second push-ups, sit and reach, and long- distance running. Findings are as follows:
1. Physical fitness as correlated with the health of male students aged 13-15 years exhibited means as follows: BMI (kilograms/m3) was at 19.97, 19.22, and 20.01, respectively. Subcutaneous fat (percentages) was at 16.46, 22.16, and 22.68, respectively.
Sit-ups (times) were at 27.87, 27.86, and27.89, respectively. Push-ups (times) were at 15.79, 15.82, and 15.87, respectively. Sit and reach (centimeters) was at 5.79, 6.38, and 5.75, respectively. Long- distance running (minutes) was at 11.94, 12.34, and 11.92, respectively.
2. Physical fitness as correlated with the health of female students aged 13-15 years exhibited means as follows: BMI (kilograms/m3) was at 18.38, 19.99, and 20.03, respectively. Subcutaneous fat (percentages) was at 15.21, 20.42, and 23.23, respectively. Sit-ups (times) were at 26.42, 27.92, and 27.81, respectively. Push-ups (times) were at 16.34, 15.80, and 15.95, respectively. Sit and reach (centimeters) was at 8.23, 5.78, and 5.78, respectively. Long-distance running (minutes) was at 12.30, 11.93, and 11.93, respectively.
3. The classification of the level of physical fitness as correlated with the health of male students, aged 13-15 years By Health-Related Physical Fitness Test for Thai children aged 7-18 years showed that BMI was at an appropriate level for all three age ranges. The percentage of subcutaneous fat was at a proportional level, rather fat, and rather fat, respectively. The strength and abdominal muscular endurance were at a low level for all three levels. The strength and endurance of arm muscles and upper body muscles were at a low level for all three levels. The flexibility of tendons at joints and bones were at low levels for all three levels. The strength and endurance of the respiratory system and the circulatory system were at a moderate, moderate, and low level, respectively.
4. The classification of the level of physical fitness as correlated with the health of female students aged 13-15 years By Health-Related Physical Fitness Test for Thai children aged 7-18 years was as follows: BMI was at an appropriate level for all three age ranges. The percentage of subcutaneous fat was at the levels of rather thin, appropriate, and rather fat, respectively. The strength and endurance of abdominal muscles were at a moderate level for all three levels. The strength and endurance of arm muscles and upper body muscles were at a low level for all three levels. The flexibility of tendons at joints and bones was at moderate, low, and low for all three levels. The levels of strength and endurance of the respiratory system and the circulatory system were at a moderate level for all three levels
