Improving Exercise Capacity With a Tailored Physical Activity Intervention

An analysis of covariance (ANCOVA) model will be used to assess post-intervention group differences in VO2, adjusted for baseline peak VO2.

Measured on a continuous scale and will be analyzed using a repeated measures ANCOVA (RMANCOVA) approach.

The Hopkins Verbal Learning Test (HVLT-R) consists of memorization of a list of words to test the ability to recall immediately after memorization (immediate recall) and after a 20-minute delay (delayed recall). This test has three parts and two alternate forms. Total scores could range from 0 to 30. Lower raw scores indicate difficulties with the task.

The Controlled Oral Word Association Test is a verbal fluency test in which participants are asked to say as many words as possible from a given category and in a specified timeframe (typically 60 seconds). COWAT is measured by calculating the total number of acceptable words produced for at the given letter of the alphabet. Errors and perseverations (word repetitions) are not included in this score.

The digit span backward test is used to assess working memory. Participants are given a series of digits and asked to repeat them backward. The item score is the sum of the scores on the two trials for that item (range=0-2). The total raw score for backwards digit span is the sum of the item scores; maximum backwards digit span total raw score is 16 points.

The Trail Making Test (TMT) asks patients to connect consecutive "targets" (numbers and/or letters) on a page arranged in a specific geometric pattern. Scoring is based on time taken to complete the test (e.g. 35 seconds yielding a score of 35) with lower scores being better.

Measured on a continuous scale and will be analyzed using a repeated measures ANCOVA (RMANCOVA) approach.

FACT-Lym is 42-item questionnaire to assess the quality of life for lymphoma patients. 5-point Likert scale - 0 (not at all) to 4 (very much). Subscale domains: Physical Well-Being, Social/Family Well-Being, Emotional Well-Being, Functional Well-Being, Lymphoma Subscale. Some items are reverse scored. Subscales scores are added to get the total score. The higher the score, the better the quality of life. Scores can range from 0-168.

FACT-B is a 37-item Functional Assessment of Cancer Therapy-Breast (FACT-B) that measures five domains of health-related quality of life in breast cancer patients. These include physical, social, emotional and functional well being on a Likert scale 0-4 with (not at all) to 4 (very much). The higher the score, the better quality of life. Scores can range from 0-148.

Questionnaire to assess the difference in the level of fatigue participants experience will performing study interventions. 5-point Likert scale - 0 (not at all) to 4 (very much). The higher the score the higher level of fatigue participants experience. Score range 0-52.

The questionnaire is a 4-item measure used to classify participants' activity levels during a typical 7-day period based on how many times on average participants exercise more than 15 minutes during their free time of strenuous, moderate or mild exercise.

Participants will be asked to maintain balance for up to 30 seconds in three positions characterized by a progressive narrowing of the base support: heel of one foot beside the big toe of the other foot (semi-tandem position), heel of one foot in front of and touching the toes of the other foot (tandem position), and single leg stand.

The repeated chair stand test will be performed using a straight-backed chair placed with its back against a wall. Participants will be first asked to stand from a sitting position without using their arms. If they can perform the task, they will then be asked to stand up and sit down five times as quickly as possible. The time to complete the task will be recorded.

The gait speed test will assess the participant's ability to walk 4 meters. Participants will be instructed to start at a marked walking course with toes touching the start line and when cued to start, will begin walking at their usual speed. The time to walk from the starting line to the end of the 4-meter walk will be recorded

Grip strength will be assessed using an isometric handgrip dynamometer while the participant is seated with the head facing straight ahead. The elbow should be bent at a 90 degree angle and the wrist should be at the mid-prone position. The participant should exert maximally and quickly (about 1 second) and two trials should be made alternately with each hand, with at least 30 seconds between trials for the same hand (recorded in kilograms).
