Prostate cancer survivors frequently experience pelvic floor dysfunction, reduced lower-limb muscle coordination, persistent fatigue, and systemic inflammatory alterations following treatment, all of which contribute to impaired functional recovery and reduced quality of life (QoL). Kegel exercise, is widely recommended to improve urinary continence and pelvic stability, while aerobic exercise has demonstrated additional benefits for systemic inflammation and cancer-related symptoms. However, limited randomized controlled trials have examined the combined effects of pelvic floor and aerobic exercise on peripheral muscle function, inflammatory cytokines, and QoL in prostate cancer survivors. Thus, this study investigated the effects of a structured combined Kegel and aerobic exercise program on adductor longus (AL) muscle function, circulating cytokine responses, and QoL in prostate cancer survivors. In this randomized controlled trial, 60 prostate cancer survivors were randomly assigned to either a combined exercise group (KEG+AE, n = 30) or a usual care control group (CON, n = 30). The intervention group participated in supervised Kegel and moderate-intensity aerobic exercise training 3 times per week for 12 weeks, while the CON received standard care without structured exercise participation. AL muscle contractile function was assessed using tensiomyography. Circulating inflammatory cytokines were analyzed using enzyme-linked immunosorbent assay techniques. QoL was evaluated using the European Organisation for Research and Treatment of Cancer QoL Questionnaire (EORTC QLQ-C30). Outcome variables were assessed at baseline and after the intervention period. Group × time interaction effects were examined using RMA. Significant interactions were observed for adductor longus contractile function parameters, indicating improved neuromuscular performance following the combined exercise intervention (p < 0.05). Circulating pro-inflammatory cytokine levels were significantly reduced, whereas anti-inflammatory cytokine responses improved in the in the KEG+AE compared with CON (p < 0.05). In addition, global health status/QoL scores significantly increased in the KEG+AE, accompanied by improvements in physical functioning and reductions in fatigue-related symptoms (p < 0.05). As a conclusion, a structured combined Kegel and aerobic exercise program improves AL muscle contractile function, modulates inflammatory cytokine responses, and enhances QoL in prostate cancer survivors.
