OBJECTIVES To assess the effects of interventions to promote exercise behaviour in sedentary people living with and beyond cancer and to address the following questions : Which interventions are most effective in improving aerobic fitness and skeletal muscle strength and endurance ?
What adverse effects are attributed to different exercise interventions ?
Which interventions are most effective in improving exercise behaviour amongst patients with different cancers ?
Which interventions are most likely to promote long-term ( 12 months or longer ) exercise behaviour ?
What frequency of contact with exercise professionals is associated with increased exercise behaviour ?
What theoretical basis is most often associated with increased exercise behaviour ?
What behaviour change techniques are most often associated with increased exercise behaviour ?
Exercise improves body fat, lean mass, and bone mass in breast cancer survivors.
Given the negative effects of a breast cancer diagnosis and its treatments on body weight and bone mass , we investigated the effects of a 6-month r and omized controlled aerobic exercise intervention vs. usual care on body composition in breast cancer survivors . Secondary aims were to examine the effects stratified by important prognostic and physiologic variables . Seventy-five physically inactive postmenopausal breast cancer survivors were recruited through the Yale-New Haven Hospital Tumor Registry and r and omly assigned to an exercise ( n = 37 ) or usual care ( n = 38 ) group . The exercise group participated in 150 min/week of supervised gym- and home-based moderate-intensity aerobic exercise . The usual care group was instructed to maintain their current physical activity level . Body composition was assessed at baseline and 6-months through dual-energy X-ray absorptiometry ( DXA ) by one radiologist blinded to the intervention group of the participants . On an average , exercisers increased moderate-intensity aerobic exercise by 129 min/week over and above baseline levels compared with 45 min/week among usual care participants ( P < 0.001 ) . Exercisers experienced decreases in percent body fat ( P = 0.0022 ) and increases in lean mass ( P = 0.047 ) compared with increases in body fat and decreases in lean mass in usual care participants . Bone mineral density ( BMD ) was also maintained among exercisers compared with a loss among usual care participants ( P = 0.043 ) . In summary , moderate-intensity aerobic exercise , such as brisk walking , produces favorable changes in body composition that may improve breast cancer prognosis
