Ten active females aged from 41- to 57-year old, each were recruited from an association of women's volleyball and jogging clubs. All subjects had a history of at least 15 years of participating in their sports. Age matched 10 sedentary females volunteered as controls. Evaluations of the subjects were made to determine if differences existed in the serum levels of total cholesterol, HDL-chole-sterol, T-C/HDL-C ratio, or triglycerides between groups with contrasting levels of physical activity habits. The jogging group demonstrated significantly higher HDL-C and lower triglycerides as compared to those of the sedentary controls while the vollyball group which is not considered as a typical aerobic exercise failed to do. A significantly higher value of Vo_<2max> was shown in the jogging group, and Vo_<2max> was significantly and positively correlated with HDL-C concentrtion and negatively associated with T-C/HDL-C ratio, and TG concentration. Isokinetic muscle strengths of the lower limb and bone density on the os calcis were also measured, and the higest values of the two parameters were recorded in the volleyball group while the lowest values were seen in the sedentary group. The bone density was significantly and positively correlated with the values of peak torque of the knee extensors. The results of the present study suggests that habitual jogging which is defined as aerobic is superior to habitual volleyball when an objective of the training is to lower cardiovascular diseses. However, when a purpose of training is to increase bone density, volleyball is more effective.
