The graph below shows the results of a medical experiment recording the heartbeat rates of two people climbing the Belfry of Bruges, one of whom suffers from a height-related phobia. Write a report for a university lecturer comparing the results of the experiment.
*This IELTS writing task was inspired by a short story available for reading here
The graph compares the heartbeat rates of two people measured during an ascent of the Belfry of Bruges: Edie, a relatively fit woman in her late twenties, and Edward, a man of the same age and comparable level of fitness, but with a severe fear of heights. It could be clearly observed from the graph that their heartbeat rates are distinctly different.
The values recorded in the short period prior to the climb show a parallel rise in both Edie and Edward by 20 beats, from 95 to 115 and 70 to 95 respectively. However, at that point, but still before the ascent, differences start to appear. While Edie’s heartbeat drops slightly, to 110, Edward’s goes up to 127. During the three phases of the climb, corresponding roughly to three sections of the tower, Edie’s values balance between 110 at the start and 125 at the top. Over the same time Edward’s heartbeat is continuously on the increase – it starts at 127 beats in the first section of the tower to reach its peak of 200 at the top, marking a difference of 90 beats between him and Edie. Individually, overall differences between the values at the ground level and top are only 25 beats for the woman, and a staggering 130 for the man.
In conclusion, a dramatic global increase in heartbeat rate can be clearly seen in phobia-gripped Edward. By contrast, Edie’s rate remains relatively stable throughout, equaling the value of 110 beats at the start, almost 50% lower than her companion.255 words
Heartbeat in the mountains… That brings some memories back, doesn’t it? I suppose mine would be more or less like Edward’s, as mountain climbing is definately no fun for me. I’ve just never been able to understand what’s so special about mountains – bunches of rocks squeezed together at a special time period a long long time ago… It would be nice if having climbed a mountain, having made quite an effort to get there, one could be rewarded with some kind of experience that would not be easily forgotten. For me, treetops and rocks seen from above are not at all satisfactory in that respect. Long, solitary walks along the seashores, on the other hand, are a completely different matter.
