The line chart compares the proportion of European individuals going to gyms once a month or more in 4 different age groups from 1990 to 2010, at four-year intervals.
Overall, there were increasing trends in all categories, with the most significant rise observed in the rate of the 25-34 age group. Additionally, this figure for the people who were 45 and over was lower than those of the remaining groups for the majority of the period.
At the beginning of the period, the 25-34 group had the highest percentage of gym participants, at nearly 10%, which then ascended consistently to five-fold, at about 50% at the end of the timeframe. People aged from 25 to 34 years old also adopted a somewhat similar upward trend but to a lesser extent. Starting at nearly 9% in 1990, it converged with the 18-24 group at around 28% in the next 8 years. After that, it surged to approximately 60%, after a considerable decline to 50%.
Concerning the remaining groups, nearly 8% of people aged from 35 to 44 years old going gyms, which then rose to nearly 20% in 2002. Following by leveling off stability in the next 4 years, it witnessed a significant growth of 20%, from 20% to 40% in 2010. Finally, the figure for gym participants aged over 45 was approximately 3% in 1990 and grew gradually to just over 20% at the end of the surveyed period.
