Interventions to promote exercise in cancer survivors who report better levels of adherence share some common behaviour change techniques .
These involve setting programme goals , prompting practise and self-monitoring and encouraging participants to attempt to generalise behaviours learned in supervised exercise environments to other , non-supervised context s. However , expecting most sedentary survivors to achieve current guideline recommendations of at least 150 minutes per week of aerobic exercise is likely to be unrealistic .
BACKGROUND The beneficial effects of regular exercise for people living with or beyond cancer are becoming apparent .
However , how to promote exercise behaviour in sedentary cancer cohorts is not as well understood .
A large majority of people living with or recovering from cancer do not meet exercise recommendations .

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 ?
Inflammation and psychosocial factors mediate exercise effects on sleep quality in breast cancer survivors: pilot randomized controlled trial.
OBJECTIVE To improve mechanistic underst and ing , this pilot r and omized controlled trial examined mediators of an exercise intervention effects on sleep in breast cancer survivors ( BCS ) . METHODS Forty-six postmenopausal BCS ( ≤Stage II , off primary treatment ) were r and omized to a 3-month exercise intervention or control group . Intervention included 160 min/week of moderate intensity aerobic walking , twice weekly resistance training ( resistance b and s ) , and six discussion groups ( to improve adherence ) . Blinded assessment s at baseline and post-intervention included sleep disturbance ( PSQI and PROMIS ® ) , objective sleep quality ( accelerometer ) , serum cytokines , accelerometer physical activity , cardiorespiratory fitness , body composition , fatigue , and psychosocial factors . Mediation was tested using Freedman-Schatzkin difference-in-coefficients tests . RESULTS When compared with control , the intervention group demonstrated a significant increase in PSQI sleep duration ( i.e. , fewer hours of sleep/night ) ( d = 0.73 , p = .03 ) . Medium to large but non-significant st and ardized effect sizes were noted for PSQI daytime somnolence ( d = -0.63 , p = .05 ) and accelerometer latency ( d = -0.49 , p = .14 ) . No statistically significant mediators were detected for PSQI sleep duration score or accelerometer latency . Daytime somnolence was mediated by tumor necrosis factor-alpha ( mediated 23 % of intervention effect , p < .05 ) , interleukin (IL)-6:IL-10 ( 16 % , p < .01 ) , IL-8:IL-10 ( 26 % , p < .01 ) , and fatigue ( 38 % , p < .05 ) . Mediating or enhancing relationships for several of the sleep outcomes were noted for accelerometer physical activity , PROMIS ® fatigue , exercise social support , and /or physical activity enjoyment . CONCLUSIONS Inflammation and psychosocial factors may mediate or enhance sleep response to our exercise intervention . Further study is warranted to confirm our results and translate our findings into more effective interventions aim ed at improving sleep quality in BCS
