BACKGROUND. Advice to rest and take things easy if patients become fatigued during radiotherapy may be detrimental. Aerobic walking improves physical functioning and has been an intervention for chemotherapy-related fatigue. A prospective, randomized, controlled trial was performed to determine whether aerobic exercise would reduce the incidence of fatigue and prevent deterioration in physical functioning during radiotherapy for localized prostate carcinoma. METHODS. Sixty-six men were randomized before they received radical radiotherapy for localized prostate carcinoma, with 33 men randomized to an exercise group and 33 men randomized to a control group. Outcome measures were fatigue and distance walked in a modified shuttle test before and after radiotherapy. RESULTS. There were no significant between group differences noted with regard to fatigue scores at baseline (P ϭ 0.55) or after 4 weeks of radiotherapy (P ϭ 0.18). Men in the control group had significant increases in fatigue scores from baseline to the end of radiotherapy (P ϭ 0.013), with no significant increases observed in the exercise group (P ϭ 0.203). A nonsignificant reduction (2.4%) in shuttle test distance at the end of radiotherapy was observed in the control group; however, in the exercise group, there was a significant increase (13.2%) in distance walked (P ϭ 0.0003). CONCLUSIONS. Men who followed advice to rest and take things easy if they became fatigued demonstrated a slight deterioration in physical functioning and a significant increase in fatigue at the end of radiotherapy. Home-based, moderateintensity walking produced a significant improvement in physical functioning with no significant increase in fatigue. Improved physical functioning may be necessary to combat radiation fatigue. Cancer 2004;101:550-7.
We retrospectively analysed acute radiation toxicity data for patients who had participated in a randomised controlled study in our centre in order to assess the impact of aerobic exercise on acute rectal and bladder morbidity during treatment. Data from 65 of 66 patients were analysed: 33 allocated into a control group (standard advice) and 33 into an exercise group (aerobic walking for 30 min at least three times per week) during 4 weeks of external beam radiotherapy; one patient in the exercise group withdrew after randomisation before starting radiotherapy. There was a trend towards less severe acute rectal toxicity in the exercise group with a statistically significant difference in mean toxicity scores over the 4 weeks of radiotherapy (P=0.004), with no significant difference in bladder toxicity scores between the two groups (P=0.123). The lack of an association for severity of bladder toxicity could be attributed to the confounding effect of lower urinary tract symptoms from their prostate cancer. Keeping active and being asked to adhere to a well-defined exercise schedule appears to reduce the severity of rectal toxicity during radiotherapy to the prostate.
This study evaluated the effects of a personal-disclosure mutual-sharing (PDMS) intervention on team cohesion and communication among 21 male professional soccer players from a top division club within the United Kingdom (UK) before an important match in the latter stages of a domestic cup competition. Data from the Group Environment Questionnaire (GEQ) and the British Scale for Effective Communication in Team Sports (BRSECTS) showed no statistically significant changes in cohesion or positive and negative communication from pre to postintervention (i.e., pretest to posttest); yet the team performed above their expectations in the important match only to lose in a penalty shoot-out. Social validation data further revealed that most players felt the intervention was worthwhile and benefitted the team by enhancing closeness, understanding of teammates, and communication. We discuss strategies and guidance for sport psychologists considering a PDMS intervention in the context of professional sport teams. Future research directions considering the effects of PDMS with other professional and youth UK sports, collective efficacy, and social identity is outlined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
