A Study Of Aerobic Dance On Health Conditions And Related Sickness Of University Female Students

Introduction

Although researchers have thoroughly documented the benefits of aerobic exercise in promotion of physical and health conditions, few studies have examined health condition and types of sickness in relation to aerobic dancing causing by the Gymnasium environment. The purpose of this study was to investigate the health condition and types of sickness of university female students.

Methods

Total 116 female participants from Hong Kong Institute of Education were selected and divided into three groups according to different training level: Non-exercise (NE) group (No aerobic experience, N=40 ), short training (ST) group (10 weeks, N =39 ), and long training (LT) group (20 weeks, N = 37). A18-items questionnaire was used to exam female students’ health conditions and types of sickness. Body composition, frequency index of common diseases and
the health index of physique were analyzed to illustrate the different health conditions among students with different aerobic training levels.

Results

The results of this study showed that 1) frequency of rachitic, rhinitis and pneumonia were slight different between NE and ST groups (p> 0.05). 2) Rest heart rate had a tendency of decrease for NE and LT groups (p< 0.05). After 20 weeks’ training, diastolic pressure of female students was gradually reduced (p< 0.05), and systolic pressure was increased slightly but had no significant differences (p< 0.05). 3) Frequency of getting cold/flu were remarkably decreased between ST and LT groups (p<0.01). 4) Joint soreness and muscular soreness for LT group were significantly reduced (p<0.05). 5) Frequency of having neurasthenia were also reduced greatly (P<0.05). Because ST group had only trained for 10 weeks, participants’ system of neurasthenia had no significant improvement. 6) Frequency of dysmenorrheal were greatly reduced for LT group (p<0.01). 7) In terms of nutritious, both ST and LT groups showed a good appetite. There was no significant difference between the training groups and NE in selecting nutritious food. 8) The BMI were smaller than group I (P2.1=0.043, P3-1=0.002) and the BFR were larger than group 1(P3-1=0.000, P3.2=0.001) and There is no difference in BMI and BFR between ST and LT groups. 9) The rate of dystrophy in LT group was nearly the same (p=0.13). But P-value was very low.

Discussion/Conclusion

After 20 weeks training, there is an improvement in female students’ heart and lung function, immunity, nutrition and digestion function, as well as their comprehensive health condition and physical fitness which lead to being more energetic. Frequency of having cold, flu and related diseases, such as body fat, neurasthenia and dysmenorrheal, were significantly reduced for ST and LT groups. The finding of this study indicated the types of sickness among different training levels, and aerobic exercise can significant promote health conditions in female students who participate in Aerobic exercises for a longer time.
