Description
Training the bench press exercise on a traditional flat bench does not induce a level of instability as seen in sport movements and activities of daily living. Because of this, many new types of equipment have been created in an attempt to induce instability, such as the COR Bench. 15 males and 7 females between the ages of 18 and 30 were recruited for the present study, which tested two forms of instability: using one dumbbell rather than two, and lifting on the COR bench compared to a flat bench. Thusly, EMG was used to measure muscle activity in four separate conditions of unilateral bench press movements: on a flat bench with one dumbbell, on a flat bench with two dumbbells, on the COR Bench with one dumbbell, and on the COR Bench with two dumbbells. Results indicated that lifting with one dumbbell compared to two dumbbells on the flat bench significantly increased muscle activity across all four muscles being analyzed (pectoralis major, p = .005; middle trapezius, p = .008; external obliques, p = .004; and internal obliques, p = .003), but lifting with one dumbbell compared to two dumbbells on the COR Bench only significantly increased muscle activity in the middle trapezius (p = .001), external obliques(p = . 032), and internal obliques (p = .001). The only muscle to exhibit a significant increase in muscle activity when going from one dumbbell on the flat bench to one dumbbell on the COR Bench was the middle trapezius (p = .010). These results imply that the COR Bench itself does not increase muscle activity as much as switching from two dumbbells to one dumbbell, regardless of the bench being used.

Description
Physical activity has been shown to be effective in primary and secondary prevention of chronic diseases such as diabetes, cancer and cardiovascular disease (Warburton, Nicol & Bredin, 2006). Women tend to be much less active than males and are henceforth at a greater risk for developing these conditions (Biddle & Mutrie, 2008). This study addresses what impact type of physical activity in adolescence has on adult physical activity levels in the female population. Specifically, the study focuses on coordination and performance activities in adolescence, and how adult physical activity levels compare to both sedentary adolescents and adolescent endurance and ball sport athletes. Ninety-six female participants that were ages 20-29 (N=53) and 30-39 (N=43) were asked to fill out a survey about their adolescent activity levels and their current activity levels. Those participants who identified as participating in coordination and performance activity (N=43) were compared to those who were sedentary (N=14) and then further compared to those who engaged in other types of adolescent activity (N=39). It was determined that coordination and performance activities during adolescence did have a significant effect on frequency of female adult physical activity when compared to their sedentary counterparts (p=0.015). Adolescent endurance and ball sport athletes did tend to have a greater frequency of current activity in adulthood than those involved in coordination and performance activities, which was attributed to a greater frequency of practice per week in those sports. In conclusion, introducing a frequent amount of physical activity the female adolescent enjoys increases their likelihood of frequently engaging in physical activity as an adult.
