Peer support did not resolve long-term exercise adherence gaps after cancer
Both exercise groups met safety criteria, but neither met attendance or intensity targets across the year.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Among these cancer survivors, adding peer support to high-intensity interval training did not bring attendance or exercise intensity up to the study's feasibility targets. Both groups met the safety criteria and targets for session duration and exercise mode. The findings concern sustaining this program after supervised training, rather than its effects on cancer outcomes.
The abstract reports performance against preset feasibility criteria, without a direct statistical estimate of the peer-support effect. Its safety findings apply to the participants and program studied.
What researchers found
Study attrition
Peer support versus exercise alone over 12 months; the support group met the preset attrition criterion, but the exercise-only group did not.
What support involved
Participants first completed supervised training. They were then assigned either ongoing contact from people with lived cancer experience or no peer support, while access to local gyms was provided to both groups.
Safety and feasibility differed
There were no severe adverse events, although less severe events occurred. Meeting the safety criteria did not mean the program was easy to sustain: attendance and prescribed intensity remained difficult in both groups.
