The line graph illustrates the proportion of people attending GYM across three age groups from 1984 to 2003.
Overall, there was an upward trend in most age groups, except for 45-65 individuals. In addition, while the 26-45 age group was initially the highest, it was surpassed by 16-25 individuals at the end of the period.
In 1984, the percentage of 26-45 people was the highest, starting at 30%, with a subsequent slight increase of 10% in 1989 before declining slightly to 35% in 1994. From 1994 onwards, this figure grew gradually to reach the rate of approximately 55% at the end of the period. In contrast, in the first year, the 46-65 age holds the second place with around 26% of individuals attending the GYM, followed by a slight increase, reaching 30% five years later before dipping to 15% in 2003.
Regarding the remaining groups, about 15% of young adults went to the GYM in 1984, after which it surged more than three times to nearly 65% in 2003. Similarly, but to a lesser extent, can be seen in the figure for elderly people, which increases from just under 10% in 1984 to nearly 15% in 1994, then decreases minimally to 10% five years later, with a final rise to exactly 20% in the final year of the period.
