The effects of different life styles on heart rate changes in different stage when riding the vertical drop facility

摘要

The exciting facilities attracted lots of riders. This combination of different directions and forces cause different excitement. Vertical drop was most popular facility which drove the rider from highest place to the lowest place within a very short period of time. Dramatical changes in direction and force will affect the cardiovascular system. However, different life styles may have different effects when they ride in this facility. The purpose of this study was to evaluate the effects of different life styles on heart rate changes in different stages when the subjects rode in the vertical drop facility. Forty five subjects were recruited to take part in this study, and were divided into 3 groups: the elite athletes group, the regular exercisers group, and the sedentary group. All subjects put on k4b2, and took a rest for 30 minutes, and then rode in the vertical drop facility to the highest place, and remained still for 10 seconds (the initial stage), and then fell down to the ground within 3 seconds. Finally, the subjects were horizontally sent to the exit, and stayed at their seat, resting for 5 minutes. Heart rates were acquired from k4b2 in initial stage, during the riding for the maximal heart rate, and 5 minutes after riding. One-way ANOVA followed by the Scheffe's multiple comparisons procedure was employed to compare the 3 groups. Significant level was set at .05. The conclusions of this study are that regular exercisers and elite athletes posses better autonomous nerve system to control their heart function when they confront tremendous pressure; Five times of gravity changed in 3 seconds may be too great for people to react to, and the regular exercisers group and the elite athletes group had better cardiovascular function than the sedentary group in recover rest heart rate.
