Section 1.

General Introduction Approximately 51% of Canadian adults are

inactive(Canadian Fitness & Lifestyle Research Institute, 2004)

At least 60% of the global population fails to achieve the minimum recommendation of daily physical activity

(World Health Organization , 2006)

20-50% withdrawal rate within the first 6 months of an exercise program

(Dishman, 1988; Oldridge, 1984; Ward & Morgan, 1984)

Increasing Physical Activity Behaviours?

Researchers have sought to identify factors associated with physical activity behavior

(Biddle, 1995; Manley, 1996; USDHHS, 1990)

Some researchers have focused on the context in which exercise and physical activity occur

No quick fixes, no simple solutions

Section 2.

The Issue of Personal Preferences

The most common contexts for physical activity are group-based or individually-based

Iverson, Fielding, Crow, & Christenson (1985)

What do people most prefer??What do people most prefer??

Beauchamp, Carron, McCutcheon, Beauchamp, Carron, McCutcheon, & Harper (2007) & Harper (2007)

Surveyed individuals in their 30s (n = 124), 40s (n =

222), 50s (n = 364), 60s (n = 185), and 70+ (n = 52) on their preference for exercising

Beauchamp, et al. (cont.)

At every age, respondents showed a stronger preference to exercise in groups versus alone At every age, respondents preferred to exercise in groups with similarly aged individuals At every age, respondents showed the least preference for the most distal age category

geographic location

The Issue of Fitness Leader Support

“the exercise leader is the pivot on which the success or failure of a program will depend”

(Oldridge, 1977)

“the exercise leader is the single most important variable [from among the 30 we tested] influencing drop out behavior”

Franklin (1988)

The Issue of Class Size

Class size is associated with perceptions of instructor effectiveness.

(Prossin & Carron, 1989)

Class size is associated with group cohesiveness

(Carron & Spink 1990)
