Twelve weeks of intermittent exercise training increased BMD, intermittent exercise capacity, and V˙O2max in PM and PRM, with PM also having positive changes in body composition. Additional 40 wk of training with a reduced frequency was sufficient to preserve these physiological adaptations and also improve blood glucose regulation in PM.

Abstract:The aim of this study was to investigate the levels of motivation associated with the participation in floorball (indoor hockey) and spinning, and how these levels of motivation predicted continuation. A sample of 66 middle-aged women participated in a 12-week intervention of either floorball or spinning. They filled out the Sport Motivation Scale in week 2 and week 11 of the intervention, and data was also collected on their continuation six and 12 months after the intervention. A repeated measures MANOVA showed that participants in the floorball group had higher levels of intrinsic and self-determined extrinsic motivation for the activity during the intervention period, suggesting that floorball is a more motivating activity. In addition, the introjected regulation extrinsic motivation increased in both groups during the intervention period. Intrinsic motivation, as well as extrinsic motivation introjected regulation, predicted participants' continuation six and 12 months after the intervention, suggesting that motivation as viewed in a Self-Determination Theory perspective is important for exercise continuation.
