- Abstract
- The purpose of this research is to prepare exercise stability/safety by predicting possible dangerous situations during competitions in advance and presenting appropriate exercise intensity based on TCD(Transcranial Doppler ultrasound) analysis of Systolic, Diastolic and Mean Blood Flow Velocity, Pulsatility Index(PI) and Resistive Index(RI) from MCA according to exercise intensity as well as at rest. The subjects were 10(ten) Soccer and Judo players respectively from high school over 5 years in experience. To analyze Cerebral Blood Flow, PI and RI Changes according to exercise intensity, treadmill test was performed among single group at rest and with moderate, high and maximal intensity. In comparison with the velocities at rest, Systolic Velocity was increased at moderate and high intensity but it was decreased at maximal intensity for both groups(p<0.05). Diastolic Blood Velocity and Mean Blood Velosity for the Soccer players were increased at moderate and high intensities but it was decreased at maximal intensity(p<0.05). In case for the Judo players, they were increased at moderated intensity but they were decreased at high and maximal intensities (p<0.05). On the other hand, Pulsatility and Resistive Index were increased at all the other intensities (p<0.05). In a repeated measured 2-way ANOVA, there were not significant differences between the exercise types and intensities (p<0.05). But there were significant differences between the each factors, Systolic Blood Velocity, Diastolic Blood Velocity, Mean Blood Velosity, Pulsatility Index and Resistive Index, and the various exercise intensities in a repeated measured 1-way ANOVA (p<0.05).
