Abstract

Background: Patients undergoing chemotherapy are two to three times more likely to experience insomnia, with the highest prevalence reported among breast cancer patients. This condition markedly reduces quality of life. This study aimed to assess whether a low-intensity aerobic exercise program using a stationary bicycle could alleviate insomnia and improve patients’ quality of life. Methods: A randomized controlled trial was conducted at Dr. Soetomo General Academic Hospital, Surabaya, Indonesia, involving female breast cancer patients undergoing chemotherapy. Participants were assigned to either a treatment group, which performed low-intensity cycling twice weekly for eight weeks, or a control group with no exercise intervention. Changes in insomnia severity and quality of life were assessed using validated questionnaires before and after the intervention. Results: Among the 20 participants who completed the study, the treatment group showed a significant reduction in insomnia severity (p < 0.001) and greater improvements in physical function, symptom management, and overall well-being compared to the control group. Conclusion: Low-intensity aerobic exercise on a cycle ergometer is a safe and effective way to reduce insomnia and improve quality of life in breast cancer patients undergoing chemotherapy.

Abstract

Background: Low physical activity reduces muscle strength and proprioception, increasing injury risk. Neuromuscular electrical stimulation (NMES) and hybrid training aim to enhance proprioception by strengthening muscles. This study compared the effects of a modified hybrid strength training program and Russian protocol NMES on knee joint position sense (JPS) in healthy, untrained men. Methods: Sixteen untrained males were randomly allocated to either the hybrid training group or the NMES group. Both groups exercised three times a week for four weeks. An isokinetic dynamometer was used to measure JPS at 30° and 60° on both dominant and non-dominant legs before and after the intervention. Results: Both interventions significantly improved JPS across all tested angles. In the hybrid group, improvements were observed in the dominant leg at 30° (p = 0.028) and 60° (p = 0.009), and in the non-dominant leg at 30° (p = 0.033) and 60° (p = 0.008). The NMES group showed similar improvements at 30° and 60° in both legs (p < 0.05). No significant differences were found between groups. Conclusion: Modified hybrid strength training and Russian protocol NMES both enhanced knee JPS in healthy, untrained men, with neither proving superior. Larger trials are needed to confirm comparative effectiveness and explore clinical applications.
