The effect of a six-month high intensity interval training program on health outcomes in breast, prostate and colorectal cancer survivors.

ABSTRACT: Interventions: Controlled intervention will compare microbiome changes over six-months between cancer types. All participants will complete a four-week training program, supervised by an Accredited Exercise Physiologist or equivalent. This initial program will require attendance three times per week and entail a high-intensity interval training protocol of 4x4 minute intervals at 85-95% HRpeak, with three minute active recovery bouts between each interval. Attendance will be recorded in a supervised-training logbook. Similarly, adherence to 85-95% HRpeak during intervals will be recorded. This protocol requires a total of 38 minutes exercise and all exercise will be conducted on a cycle ergometer. The purpose of this period is to ensure all participants understand the exercise protocol and are able to complete it safely during the remainder of the study. Participants will then be provided with access to a facility with all required equipment available and encouraged to complete three sessions per week for the next six months. Participants will also be advised to maintain 150 minutes of moderate intensity or 75 minutes of vigorous intensity or a combination, therefore meeting the Australian exercise oncology guidelines. Participants will keep a log of the date and duration of exercise completed. Participants will be recruited from the Brisbane area, with the intervention being run from the University of Queensland and partnered gyms in the wider Brisbane area. Primary outcome(s): Human gut microbiome taxa abundance in stool samples assessed via 16S rRNA sequencing. This composite outcome will also provide representation of microbial diversity. [Participants will deposit a stool sample within the three days immediately prior to each testing occasion. Testing time-points will be at baseline (prior to supervised training), following the 4-weeks supervised training, and at three- and six-months (primary endpoint) following supervised training.] Study Design: Purpose: Treatment; Allocation: Non-randomised trial; Masking: Open (masking not used);Assignment: Single group;Type of endpoint: Efficacy

Project description:The goal of the endurance exercise training study in young adult rats was to perform exercise training studies in young adult (6-month-old) F344 rats, and from these rats collect multiple tissues in order to provide high quality samples for detailed analysis by chemical analysis sites. Tissues were collected from 10-12 rats sedentary control rats concurrent with the collection of the 8-week training groups. The 8-week training group and controls were from the same cohort and same age at euthanasia. For the older age group, an additional set of controls (n=5-6) were collected with the 1-2 week training group. Rats were either sedentary or underwent an exercise training program. Rats were exercised on the rodent treadmill 5 days per week using a progressive training protocol designed to exercise the rats at approximately 70% of VO2max and training was performed no earlier than 10:00 am and no later than 5:00 pm over 5 consecutive days per week. Training was initiated with the treadmill set at 70% of VO2 max and 5 degrees grade for 20 minutes. The duration of exercise was increased by one minute each day until day 31 of training (start of week 7), when a duration of 50 min was reached. Speed and grade of each training session increased in larger increments due to treadmill parameters. The highest intensity and duration of training began on day 31. This intensity was maintained for the final 10 days of the protocol to ensure steady state had been achieved. If any rats were unable to perform at least 4 days of training per week they were removed from the study and euthanized. It is important to note that the starting treadmill speed varied depending on the sex and age of the rat. The initial and maximum speeds were based on VO2max measurements obtained during the pre-training testing of the compliant rats. Rats assigned to the control group followed a schedule similar to the training group. They were placed in one lane on the treadmill for 15 minutes/day, 5 days per week. The treadmill was set at 0 m/min at an incline that corresponded to the incline being used by the training group.
