　　An obvious upward trend can be observed in the proportion of visitors aged under 45. In 1984, 30% of people aged 26 to 45 worked out in gyms every month, ranking the first among all the age groups. Despite some fluctuations, from 1994, the figure kept rising substantially from 35% to 55% in 2003. Apart from that, people in their early adulthood showed mounting interest in this activity, since the figure ballooned beyond all recognition from 15% to 65%, surpassing that of the aforementioned group in 1994.

　　A different situation can be found in elder people over 45 years old. Although there was a marginal increase in the percentage of people aged 46 to 65 during the first 5 years, the figure later experienced a steady decline from 30% to 15%, trailing the data of all the other age groups in 2003. Such sports facilities were actually not popular among senior citizens above 65 years old, with only less than one-fifth of them going there throughout the 20 years. In spite of some recorded peaks and troughs, the proportion finally reached 20% in 2003.
