Abstract
This study compared the characteristics of plasma lipids in subjects with different levels of health-related physical fitness quotients (HPFQ). One hundred collegiate male students were recruited as volunteered subjects (mean age: 19.24±0.71 yrs; mean height: 172.82±5.49 cm; mean weight: 65.90±12.37 kg). Subjects underwent a series of tests of health-related physical fitness such as body mass index (BMI), sit-and-reach, one-minute sit-up, and 1,600m walk and run, for calculating the HPFQ and were then divided into three groups as low, fair, and high HPFQ on the basis of total subjects' mean quotients and standard deviation. Their venous blood was also collected and further analyzed for the characteristics of plasma lipids in the level of total cholesterol (TC), high density lipoprotein (HDL-C), low density lipoprotein (LDL-C), and triglyceride (TG). The Pearson product-moment correlation coefficient was used to assess the relationship between variables. The skew-ness statistics was used to check if the distribution of participants in HPFQ is normal. In addition, the one-way ANOVA was also used to examine the difference in plasma lipids characteristics between groups. The results showed that the HPFQ of participants were normally distributed. Strong correlations were also found between HPFQ and HDL-C, LDL-C, TG, TC/HDL-C, LDL-C/HDL-C, respectively (r=-0.45~0.40, p<.01). Subjects with low HPFQ showed a more significant difference in the level of TG, HDL-C, TC/HDL-C, LDL-C/HDL-C than subjects with fair and/or high HPFQ (F=7.04~8.78, p<.01), but greater differences were also found if grouped only by calculated HPFQ from BMI and 1,600m walk and run (F=11.44~22.68, p<.01). It was found that the HPFQ distribution in this study had a normal curve and HPFQ seemed to be able to be applied in discriminating collegiate male students' plasma lipids; however, HPFQ calculated from BMI and 1,600m walk-and-run performance can provide better and keener differentiation than the ordinary.
