Background: Reduced quality of life, cancer-related fatigue, and functional impairment are common during and after oncologic treatment. Although therapeutic exercise is effective, evidence on brief, supervised programs of moderate to vigorous intensity remains limited, despite their greater clinical feasibility. This study evaluated the effectiveness of a six-week multimodal Therapeutic Exercise Program (TEP) in patients with cancer. Methods: A randomized controlled clinical trial (NCT05816187) was conducted with 110 patients with cancer (stages I–III), assigned to either an intervention group (supervised TEP, three sessions per week for six weeks) or a control group (usual care). The program included cardiorespiratory and strength training with intensity monitored using the Rating of Perceived Exertion (RPE), as well as stretching exercises. Quality of life (QoL) was assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), fatigue using the Functional Assessment of Chronic Illness Therapy-Fatigue scale (FACIT-F), functional capacity using the Six Minute Walk Test (6MWT), and muscle strength using the 30 Second Sit to Stand Test (30s-STST) and handgrip dynamometry (HGT). Analyses of covariance (ANCOVA), responder analyses based on the Minimal Clinically Important Difference (MCID), and effect sizes (ηp²) were performed. Results: The intervention group showed significant and clinically meaningful improvements in fatigue (FACIT-F: +4.53; p < 0.001; ηp² = 0.135), global QoL (+9.22; p = 0.006), physical function, functional capacity (+24.16 m in the 6MWT; p = 0.006), and muscle strength (30s-STST: +2.71 repetitions; handgrip: +3.32 kg; p < 0.001). A total of 63.3% of participants were responders for fatigue compared with 13.3% in the control group (NNT = 2.00). Functional improvements showed moderate correlations with fatigue and global health status. Among symptoms, only insomnia demonstrated a significant reduction. Conclusions: A brief, supervised, multimodal TEP of moderate to vigorous intensity appears to be an effective, safe, and clinically relevant intervention to improve fatigue, QoL, and functional capacity in patients with cancer, with potential applicability in multidisciplinary oncologic care.

Background: Due to their high toxicity, cancer treatments produce multiple sequelae, including fatigue, which has a great impact on quality of life. Therefore, the aim of this study is to evaluate the efficacy on quality of life, fatigue, and functional capacity of a short-term exercise program combining aerobic exercise, resistance training, and stretching for 6 weeks in cancer patients. Methods: The design of the study was quasi-experimental, which included a group of 30 women who were receiving or had received in the last year chemotherapy, radiotherapy, or hormonal treatment. The exercise supervised program with vigorous intensity lasted for six weeks and consisted of three distinct blocks: aerobic exercise (25 min), resistance training (20 min), and stretching exercises (15 min). Before and after starting the exercise program quality of life (EORTC QLQ-C30 questionnaire), functional capacity [6 min Walking Test (6MWT), Handgrip Test (HGT), 30-Second Sit-to-Stand Test (30s-STST)], and fatigue (FACIT-F questionnaire) were measured. Results: In the EORTC QLQ-C30 questionnaire significantly higher scores were observed in the global health status scale (p < 0.05), as well as in the functional scale in the role functioning, emotional functioning, and cognitive functioning items (p < 0.05), indicating a higher quality of life and overall health level. There was also a reduction in fatigue (p < 0.05), obtaining higher scores on the FACIT-F questionnaire after the exercise program. Additionally significant improvements are observed in 6MWT, HGT, and 30s-STST following the implementation of the exercise program (p < 0.05). Conclusions: A 6-week exercise protocol, with a vigorous intensity, including resistance training, endurance, and stretching exercises can produce significant improvements in quality of life and reduction in fatigue, as well as improve muscle strength and functional capacity.
