The aim of this study is to investigate the relationship of foot posture and foot size with balance. A hundred and thirteen healthy volunteers were recruited from undergraduate students (Male = 74, Female = 37, age range 18-22). The Foot Posture Index (FPI-6), anthropometric measurements, dynamic balance and static balance measurements were done to investigate the relationships between all the variables. Pearson product's moment correlation coefficient test was used for statistical analyses. As a result, it was found that there was a weak, negative correlation between the static balance and foot posture variables, r = -.22, n = 113, P < .005. Moreover, there was a weak positive correlation between static balance and heel breadth, r = -.19, n = 113, P < .005; and it was found that there was another small negative correlation between dynamic balance and foot length, r = -.13, n = 113, P < .005. Deficiency in foot posture may lead to some injuries by affecting on balance. This can be very important to both athletes and elderly people.

The aim of the study was to examine the the effects of aerobic and step dance exercises on hematological and blood lipids parameters. 32 university students were voluntarily participated in this study. They were randomly assigned to aerobic dance (N=16) and step dances (N=16). All groups were participated an hour aerobic or step dance exercise session 2 times in a week during 3 months. Wilcoxon Sign test was used to analyze pretest and posttest results of variables. As results, significant differences were found in the pre-and post-intervention scores for triglycerides (TC), red blood cell (RBC), and hematocrit (HCT) in Step dance group. Although there were decreases in triglycerides levels for both aerobic dance and step dance groups, only significant reduction was found in step dance group.Step dance exercises was better than aerobic dance in terms of increasing RBC and decreasing cholesterol, low density lipoproteins (LDL) cholesterol level. Aerobic dance exercises were better than step dance in terms of increasing high density lipoproteins (HDL). Moreover, when comparing the level of decreasing of Hemoglobin (HGB) significantly, aerobic dance group were better than step dance group. HCT increased significantly more in step dance group as compared with aerobic dance group.Step dance cause more increment than aerobic dance in terms of platetes (PLT) level. The data of this study indicates that step dance is more effective than aerobic dance in terms of decreasing LDL cholesterol, triglycerides and cholesterol for university students.4
