The table compares the number of people participating in five different sports across Australia from 2001 to 2009 and their proportional changes. Overall, while running, aerobics, and tennis gained more popularity over time, fewer people chose swimming and cycling. It is also evident that cycling was most preferred by Australians.  

Regarding the activities with increasing participation, running recorded the largest growth of 156% as its figure rose gradually from 1.4 to 2.2 million runners during the surveyed period. Similarly, the number of aerobics participants and tennis players witnessed an increase of 0.1 million players every four years. While the former climbed from 1.5 to 1.7 million people, the latter grew from 1 to 1.2 million, making it the least favorite activity of all time.  

Concerning the remaining exercises, there were 4.5 million cyclists in 2001, which then plunged to 3.1 million in 2005 and recovered to 3.6 million, marking a decline of 20%. Swimming observed a less significant decreasing rate of 10% yet overtook cycling to become the most popular activity with 3.8 million people.
