About this study
Official title: Effect of a Single Bout of Moderate-intensity Aerobic Exercise on Colon Cancer Cell Growth in Vitro
This study involves drawing blood samples from men before and after they perform 30-minutes of moderate-intensity aerobic exercise. The investigators will evaluate whether adding the exercise serum to colon cancer cells in a dish can reduce the growth of the cells compared to the resting serum.
Note: serum is the liquid part of the blood that carries hormones and metabolites around the body.
Read the detailed description
Regular exercise is associated with a reduced risk of developing colon cancer. However, the mechanisms underpinning the anti-cancer effect of exercise are not yet fully understood. A recent theory suggests that each time you exercise, the short-lasting spikes in circulating hormones can suppress the growth of cancer cells. Hence, every exercise bout could have a direct anti-cancer effect.
This study will recruit men with an increased of colon cancer and explore whether incubating colon cancer cells with serum collected after a bout of moderate-intensity aerobic exercise influences cell viability in vitro.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Exercise assessmentOther
The moderate-intensity aerobic interval exercise will be performed on a cycle ergometer under the supervision of trained staff in an exercise science laboratory. Participants will perform a 5 to 10-minute warm-up that begins by pedalling against a light resistance (60 W) and progressively increases in resistance until a target heart rate of 50-60% heart rate reserve is achieved. Participants will then complete 6 x 5-minute bouts at 60% heart rate reserve whilst maintaining a cadence of 60 rev·min-1, separated by 2.5-minutes of pedalling against light resistance (60 W). The session will finish with a cool-down at light resistance (60 W) lasting 10-minutes.
| Study group | Role | What they receive |
|---|---|---|
| Exercise assessment | Experimental | The exercise condition will involve venous blood samples being drawn immediately before and after a single bout of moderate-intensity aerobic interval exercise. Receives: Other: Exercise assessment |
| Resting assessment | No intervention | The resting condition will involve venous blood samples being drawn before and after 60 minutes of seated rest. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Cell viability (%)
Viability of a human colon cancer cell line (LoVo) will be assessed via quantification of the fluorescent signal by the resazurin assay (Sigma-Aldrich, Dorset, UK). Cells will be seeded in culture medium containing 10% serum from individual participants and incubated for 48 hours. Fluorescence will then be measured using a microplate reader at an excitation of 540 nm and emission of 590 nm. Background fluorescence will be subtracted from each well and then values will be normalised to fluorescence of control cells grown in 10% fetal bovine serum instead of participant serum to give a percent viability.
Measured: 48 hours

Concentration of epinephrine (pg/ml)
Systemic concentration of epinephrine will be measured from serum
Measured: Immediately before and immediately after the exercise and resting assessments

Questions about this trial
What is this clinical trial studying?
A study testing Exercise assessment in people with Colon Adenocarcinoma and Colon Cancer, run by Northumbria University at 2 sites in United Kingdom.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 20 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Cell viability (%) (time frame: 48 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04057274, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Aug 2020; AzTrials last refreshed its copy on 7 Nov 2026.
