The purpose of this study is to conduct a pilot randomized controlled trial (RCT) evaluating the feasibility and potential effectiveness of a remotely supervised exercise program (REM) in promoting adherence to an exercise prescription before and during chemoradiation.
The research team adopts an overtly pragmatic approach where our design choices are made to enhance external validity and create a parsimonious intervention that can be integrated into busy clinical practices. This is a pilot study and is not designed to definitively provide evidence for a treatment effect, but rather to establish feasibility and to optimize the intervention and study procedures in preparation for a larger trial. We will conduct a pilot RCT comparing a remotely supervised exercise program (REM) to an unsupervised exercise program (UNSUP). Data will be collected upon enrollment (T0; at least 2 weeks prior to beginning chemoradiation), immediately prior to chemoradiation (T1), immediately post-chemoradiation (T2) and 1-month post-chemoradiation (T3).

REM is designed to follow in the tradition of stepped care behavioral interventions. As such, participants who are successfully engaging in the prescribed exercise are provided minimal and automated encouragement and praise. Participants who demonstrate less adherence are given interventions that are tailored in content and intensity, depending on the level of success and the nature of the barriers to success
The control condition represents a minimalist intervention that could occur in any setting: (1) enthusiastic provision on an exercise prescription and (2) provision of a fitness device (i.e., the Garmin VivioActive) that can help participants track their exercise engagement. Participants are instructed in how to use the device to track their adherence to the exercise prescription.

Forced expiratory volume in 1 second
Pulmonary function will be measured by forced expiratory volume in 1 second (FEV1). This will be measured by a pulmonary medicine technician as part of the pre-chemoradiation (T0) exam and 1-month post-treatment (T3).
Time frame: Time 3, One month after completing chemoradiation
Diffusion capacity

Pulmonary function will be measured by the diffusing capacity of lungs for carbon monoxide (DLCO). This will be measured by a pulmonary medicine technician as part of the pre-chemoradiation (T0) exam and 1-month post-treatment (T3).
Time frame: Time 3, One month after completing chemoradiation
Forced vital capacity
Pulmonary function will be measured by forced vital capacity (FVC). This will be measured by a pulmonary medicine technician as part of the pre-chemoradiation (T0) exam and 1-month post-treatment (T3).
Time frame: Time 3, One month after completing chemoradiation
Physical Function Scale of the Patient Reported Outcomes Measurement information System (PROMIS)
The 10-item physical function scale of the PROMIS Item Bank36 will be administered to the participant by the research assistant. The items ask respondents to determine the degree to which health interferes with mobility and daily living tasks. The scale has an internal reliability coefficient of 0.81 and was found to correlate positively with quality of life and negatively with pain impact. Higher scores indicate better physical function.

Pittsburgh Sleep Quality Index
From the actigraphy data from the Garmin fitness device, we can calculate sleep onset latency (SOL), total sleep time (TST), wake after sleep onset (WASO), and sleep efficiency (SE). It is expected that increased exercise in cancer patients will follow by decreased SOL and WASO, increased TST and SE, and improvements in subjective sleep quality. The Pittsburgh Sleep Quality Index (PSQI) is a widely used measure of sleep quality, in the time frame of 2 weeks prior to the assessment. PSQI assesses a range of sleep disturbances, including symptoms of insomnia, symptoms of sleep-related breathing disorders, use of sleep medications, etc. PSQI score over 5 is indicative of significant sleep disturbances. We would expect that PSQI score would decrease following increased exercise in cancer patients.
Time frame: Time 3, One month after completing chemoradiation
Functional Assessment of Cancer Therapy-fatigue scale
The Functional Assessment of Cancer Treatment- Fatigue (FACT-F) instrument will be used to measure quality of life and, specifically, effects of cancer-related fatigue upon quality of life .37 The FACT-F is a 40-item self-report measure of health-related quality of life specifically designed for cancer patients. The first 27 items of the tool represent the general version of the FACT (FACT-G) which assesses perceived well-being in physical, social, emotional, and functional domains. The remainder of the tool addresses concerns directly relevant to fatigue. Higher scores indicate higher quality of life.
Time frame: Time 3, One month after completing chemoradiation
Dose reductions
Medical record audits will be conducted to determine the degree to which participants received the prescribed regimen of chemoradiation (performed at T2).
Time frame: Time 3, One month after completing chemoradiation
Grip strength
Grip strength has been found to effectively identify people with clinically significant weakness that correlates with disability.60 Using a JAMAR Handheld Dynamometer, the subject will hold the device in their dominant hand, with the arm at right angles and the elbow by the side of the body. No other body movement is allowed. The subject squeezes the dynamometer with maximum isometric effort and maintained for about 5 seconds. The subject should be strongly encouraged to give maximum effort. The best result from several trials for each hand is recorded with at least 15 seconds recovery between each effort.
