Abstract Background Older adults with cancer are vulnerable to declines in muscle performance (e.g., strength, speed, duration of muscular contraction), which are associated with worse cancer-related outcomes. Exercise-based interventions can mitigate these declines, but evidence of their effect among older adults with myeloid malignancies receiving outpatient treatment is limited. We explore change in muscle performance among patients in a single arm pilot study of a mobile health (mHealth) exercise intervention. Methods Patients ≥ 60 years old with myeloid malignancies receiving outpatient chemotherapy completed a home-based resistance band and walking exercise program [EXercise for Cancer Patients (EXCAP)©®] delivered via a mobile application with symptom monitoring [(Geriatric Oncology-EXCAP (GO-EXCAP)] lasting 2 cycles of chemotherapy (approximately 8–12 weeks). Clinical exercise physiologists provided instruction and ongoing support. Upper and lower extremity peak torque (maximum force, newton-meters, Nm), total work (force over entire movement, Nm), and average power (speed of force, watts, W) were assessed using the BIODEX System 4 isokinetic dynamometer. Muscle activation (motor recruitment, millivolts, mV) was captured using the BTS FREEEMG 1000. We report descriptive statistics and within-patient differences from baseline to post-intervention using Wilcoxon signed rank tests (α = 0.10) and effect size (ES, Cohen’s d, 0.20 ≤ small
