Overall, younger individuals (18-23 and 24-33) exhibited significantly higher participation rates in gym activities compared to older groups (34-43 and 44-53). The 24-33 age group saw a steady increase in attendance over time, eventually surpassing the 18-23 group, which experienced fluctuations before declining. Meanwhile, the older age groups showed a slow but consistent upward trend throughout the period.
In 1990, approximately 15% of 18-23-year-olds attended the gym regularly, rising sharply to about 22% by 1994. However, this figure then fluctuated, peaking at 25% in 2006 before plummeting to 15% in 2010. Conversely, the 24-33 group followed a more consistent upward trajectory, increasing from around 17% in 1990 to roughly 27% in 2010, making it the most active group by the end of the period.
In contrast, gym participation among older age groups remained relatively low. The 34-43 category rose gradually from about 5% in 1990 to nearly 10% in 2010, while the 44-53 group followed a similar pattern, increasing from just under 5% to around 8%. Despite their growth, these figures remained significantly lower than those of younger groups.
In summary, while younger age groups initially had higher gym attendance, the 24-33 category became the most active over time, whereas older adults demonstrated only modest increases in participation.
