About this study

Official title: Evaluation of the Prophylactic Effects of the Flavonoid Diosmin on Delayed-onset Muscle Soreness in Humans: a Randomized, Double-blinded and Placebo-controlled Single-center Clinical Trial

The potential benefits of exercise for the treatment of chronic inflammatory diseases and pain have been well documented in the scientific literature. Psychiatric, neurological, metabolic and cardiovascular diseases are examples of conditions that impact the health and quality of life of the population. Due to the effects provided by exercise, it can modify the natural course of these diseases. This concept is important to justify the efforts made by government bodies committed to promoting exercise, such as the WHO. However, the habitual practice of physical activity following the primary guidelines may be hampered by some factors, including those that support the physiological repercussions of exercise on the body, such as muscle pain. In this sense, an important complicating factor such as delayed-onset muscle soreness (DOMS), present in the post-exercise recovery period, can impair adherence and permanence in physical activity programs, thus representing a considerable barrier to exercise promotion. They can also severely impair the performance of high-level athletes. Flavonoids, present in plants, but also in foods of the human diet, are known to have several biological properties, including analgesic, anti-inflammatory, and antioxidant effects. Currently, there are still few studies that have evaluated the effects of flavonoids on the development and evolution of DOMS in humans.

Read the detailed description

Main objective:

  • Analyze the potential effects of supplementation with the flavonoid diosmin on DOMS in humans (athletes from the women's five-a-side soccer team from the city of Londrina, Paraná State, Brazil), using the proposed intense dynamic exercise protocol.

Specific objectives:

  • Evaluate whether treatment with the flavonoid diosmin reduces muscle pain induced by the intense dynamic exercise protocol;
  • Evaluate whether treatment with the flavonoid diosmin reduces systemic (serum) levels of total creatine phosphokinase (CFQ) and oxidative stress (lipid peroxidation and antioxidant capacity) induced by the intense dynamic exercise protocol;
  • Evaluate whether treatment with the flavonoid diosmin is capable of improving the reduction in muscular performance and impairment of balance induced by the intense dynamic exercise protocol.

The present project will be carried out through a randomized, double-blinded and placebo-controlled clinical study. A total of approximately 40 female athletes pertaining to the Londrina Esporte Clube (name in Portuguese of the team) women's five-a-side soccer will be recruited for the study. The choice of exclusively women individuals is due to sexual dimorphism in pain perception, thus contributing to the results being more homogeneous and reliable. The criteria for inclusion of volunteer participants in the project will be to be between 16 and 35 years old, and to be able to perform the proposed intense dynamic exercise protocol. Exclusion criteria will include locomotor system dysfunctions or use of analgesic/anti-inflammatory medication at the time of recruitment, as well as being on a calorie-restricted diet or ergogenic supplementation. The study will consist of two experimental groups, made up of healthy individuals, who will perform the proposed intense dynamic exercise protocol, as follows: 1) control group that will receive placebo supplementation (corn starch tablets at a concentration of 750 mg); and 2) intervention group that will receive supplementation with diosmin (tablets at a concentration of 750 mg). Treatment of study participants will occur orally, and everyone will ingest identical opaque capsules containing placebo or diosmin with water. The treatment protocol will be applied before the start (pre-treatment) of the intense dynamic exercise sessions, once a day, during the two days before, and on the day (immediately before) the execution of the exercise protocol. Each experimental group will consist of approximately 20 participants. The project is approved by the Research Ethics Committee (CEP) for Human Beings/Brazil Platform(protocol number 64025122.2.0000.0108). The selected participants will be informed about the objectives and methodology of the study and when there is agreement with the proposed design, the agreement to voluntarily participate in the study will be registered by means of an Informed Consent Form. The intense dynamic exercise modality proposed (concentric and eccentric contractions) for the study will follow the following approach: participants will perform a standardized muscle injury protocol that will consist of a sequence of three sets of repetitions until fatigue of bilateral muscle contractions on a leg-press machine with a 45° angle. Each The participant will have their load previously defined through the 1 repetition maximum (1RM) test, and 70% of the defined weight will be used during the intense dynamic exercise protocol. During each action, the load will be resisted with the legs placed on the leg-press supporter from full knee extension to the 90° knee flexion angle, lasting approximately 3-5 seconds. Between each series, participants will be able to take a 1-minute rest period. The intense dynamic exercise protocol that will be carried out by all participants will be supervised by the project manager and/or collaborators duly trained for such assessments. Participants' clinical signs will be monitored frequently during the activities and in case of discomfort, the activity will be stopped immediately. Analyzes of clinical and blood parameters will be carried out before the start (baseline) and after the end of the proposed intense dynamic exercise protocol (24 and 48 hours) aiming to investigate the possible effects of diosmin on DOMS and related pathological events.

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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Sergio M Borghi, Ph.D. (+55 43 999189216, sborghi@uel.br), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Muscle soreness (time frame: Basal, 24, and 48 hours after DOMS induction protocol). 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 NCT06125002, which also lists 6 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.
