About this study

Official title: Vitamins C and E Combined With Cryotherapy on the Pain, Oxidative Stress and Inflammatory Response After Resistance Exercise Session in Untrained Volunteers

Acutely resistance exercise induces inflammatory responses and leukocytosis arising of oxidative stress, that clinically manifested by pain and/or delayed onset muscle soreness (DOMS). Beginners in resistance exercise programs are more vulnerable to the effects of oxidative stress as they exhibit lower antioxidant capacity, greater lipid peroxidation and present increased perception of pain after exercises that may lead to abandonment the exercises practice. Vitamins C and E are exogenous antioxidants which are able to prevent damages caused by oxidative stress. Cryotherapy decreases temperature and reduced generation of reactive oxygen species. The aim of the present research are to investigate the effects of the concomitant of vitamins and of cryotherapy on leukocytosis, inflammatory markers, oxidative stress parameters and pain in untrained individuals submitted to a resistance exercise session.

Read the detailed description

The regular practice of physical exercises promotes anti-inflammatory effects, which reduces the mortality from all causes, especially by cardiovascular diseases. On the other hand, physical exercise induces acute inflammatory responses. Acute resistance exercises provoke mechanical and metabolic stress which may vary depending on the intensity, specificity, volume and workload. During these exercises, reactive oxygen and nitrogen species (RONS) are formed and, when its production exceeds the antioxidant enzymatic capacity (Superoxide dismutase, Catalase and Glutathione peroxidase) and non-enzymatic capacity (vitamins A, C, E and uric acid) results in oxidation of cell constituents. This state of oxidative stress promotes one inflammatory response, activation and mobilization of circulating white blood cells and induce a transitory leukocytosis, that are observed during and immediately after resistance exercises. The local neutrophilia induces the amplification of inflammatory response by feedback resulting in activation and/or mobilization of the more white blood cells. This sequence of physiological events leads to muscular remodeling although, during such process, occur functional insufficiency and the sensation of pain and/or delayed onset muscular soreness (DOMS), which deserves special attention, once may lead to interruption or abandonment of exercises, especially concerning beginners in this practice.

Numerous preventive approaches have been studied intending to minimize the inflammatory response caused by resistance exercises, including the supplementation with vitamins C (ascorbic acid) and E (alfa-tocopherol). These vitamins are exogenous antioxidants which are able to prevent damages caused by RONS and consequently attenuate the oxidative damage induced by resistance exercises. Cryotherapy is defined as the therapeutic application of any substance that removes heat from the body, thus lowering the temperature of tissues. Immersion in cold water (≤ 15ºC) is a common method of heat reduction. Cryotherapy attenuates microvascular dysfunction, and decreases temperature, metabolism and oxygen demand in the electron transport chain. As a consequence, lower amounts of RONS are produced less damage was caused to adjacent molecules. The aim of the present research are to investigate the effects of the concomitant supplementation of vitamins (C and E) and cryotherapy (immersion in water at 15ºC) on leukocytosis, inflammatory markers, oxidative stress parameters and pain in untrained individuals submitted to a resistance exercise session.

The record says: finished, as of the sponsor's last update on 17 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Delayed onset muscle soreness (points) (time frame: Assessed 24 hours after resistance exercise session). 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 NCT02902315, which also lists 16 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 17 Jul 2017.
