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 .
Psychologic Effects of Cardiovascular Conditioning: A Controlled Experiment
& NA ; Although there have been numerous studies documenting a relationship between physical fitness and psychologic functioning , few have employed the type of experimental design that would allow conclusions to be drawn regarding cause and effect . In the present study , college students were r and omly assigned to a cardiovascular conditioning program or to a control program design ed to give the appearance of physical training while minimizing cardiovascular benefits . Both groups were tested for cardiovascular fitness as well as on a number of self‐rating scales before and after the 6‐week program . The cardiovascular group demonstrated a significantly greater improvement in cardiovascular fitness than the control group and also tended to show a greater reduction in anxiety and greater increase in measures of general psychologic well‐being
