The heterogeneity in reported effects was reduced in higher quality studies , when physical activity was self-directed with some professional guidance and when there was on-going professional support .
Our review suggests that physical activity interventions have a moderate effect on self reported physical activity and cardio-respiratory fitness , but not on achieving a predetermined level of physical activity .
Due to the clinical and statistical heterogeneity of the studies , only limited conclusions can be drawn about the effectiveness of individual components of the interventions .
BACKGROUND Little is known about the effectiveness of strategies to enable people to achieve an increase in their physical activity .
OBJECTIVES To assess the effects of interventions for promoting physical activity in adults aged 16 years and older , not living in an institution .
An effective exercise-based intervention for improving mental health and quality of life measures: a randomized controlled trial.
OBJECTIVES This study investigates the effectiveness of 24-week aerobic and weight-training exercise plus behavior modification for mental health and quality of life ( QOL ) outcomes . METHODS Mental health and QOL data was collected using the Depression Anxiety and Stress Scales and SF-36 Health Status Survey , respectively . Employees from a single work-site were r and omized into either treatment or wait-list control groups . RESULTS Mental Health ( P = 0.005 ) , Vitality ( P < 0.001 ) , General Health ( P = 0.009 ) , Bodily Pain ( P = 0.005 ) , Physical Functioning ( P = 0.004 ) , Depression ( P = 0.048 ) , and Stress ( P = 0.036 ) scales significantly improved for the treatment group compared to wait-list controls after 24 weeks . CONCLUSIONS Multimodal exercise is as effective as other single-modality exercise treatments for depressive symptoms and , in contrast to other studies , does improve stress symptoms and QOL outcomes
