The line graph below illustrates the frequency of European people in different age groups took part in gyms from 1990 to 2010. Overall, the number of people aged from 25 above tended to increase at the end of the period, while those who were 18 -24 went to gyms less than others.
From 1990 to 1998, there was a fluctuation in the number of people aged 18 – 24, starting at 12% and ending at 18% at 1998, whereas people in mid-twentieth to mid-thirtieth increased moderately in the first five years, at 9%, and suddenly rocketed at 26% at 1998, more than a half of its figure in the first five years. Moreover, this trend in those who were 25 – 34 still continued to rise dramatically and reached the peak at 50% at 2006 before its slight decline and thrived at 47% at the end of the period. However, the number of teenagers and mid-twentieth people joining in the gyms fluctuated until 2000. This percentage rose slightly and peaked at the top of 30%, then the figure stood still until 2009. It witnessed a moderate decrease in 2010.
In terms of the adults and elderly people, there were no changes in these two categories. Those in 35-44 took part in the gyms regularly and went up moderately each year, starting at 5%. In addition, this percentage surged more than 30% and remained unchanged in 2010. In contrast, elderly people rose constantly from 1990 to 1997, and this figure experienced a fluctuation in the next six years before going up significantly at the end of the period, reaching more than 10%, which was higher than at the starting point.
