The table demonstrates the transformation among five distinct physical activities in Australia in terms of the number of participants from 2001 to 2009.
From an overall perspective, it is evident that three activities including running, aerobics, and tennis experienced an upward trend, whereas other criteria show a slightly downward trend, reflecting substantial opposition.
Firstly, it is clear that running stands out as the most popular activities, leading the chart with the highest proportion of change at 156%, rising dramatically from 1.4 to 2.2 over the surveyed period. However, the data of aerobics and tennis depict minimal fluctuation, remaining stable at approximately 1.6 and 1.1, respectively.
On the other hand, it is also apparent that there are several significant transformations in terms of the other metrics. The figures of swimming show an insignificant decrease from 3.7 to 3.3. Otherwise, the count of people engaging in cycling displays a sharp decline from 4.5 to 3.1, slightly increasing, and ending at 3.6, accounting for 20 percent of decreasing over the period of eight years.
