The Effect of a 2000-m Ergometer Test on Training Status Indicators and the Muscle Adaptation in Rowers (ETTETTSIAMAR)

February 21, 2025 updated by: Poznan University of Physical Education

Multi-Faced Optimization of Sports Training Focused on Training Status Energy and Muscle Adaptation to Effort

Intense physical exercise can lead to micro-damage to tissues and activation of inflammatory processes, the body's natural response to exercise-related metabolic stress. Monitoring inflammation and fatigue will enable the observation of athletes in terms of post-exercise regeneration and muscle adaptation to physical effort. The obtained results will allow for estimating the level of fatigue, minimizing the risk of injury, and will show the rate of post-exercise regeneration or its absence.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study will involve 40 members of the Polish Youth Rowing Team, both sexes, aged 19-23. The study will be held on three dates related to the specifics of the athletes' training cycle, i.e. in the preparatory period (March), the competition period (June), and the detraining period (November). The participants will perform an intensive exercise test on a rowing ergometer (manufacturer: Concept II, USA), covering a distance of 2,000 meters in the shortest possible time. The study will involve 40 members of the Polish Youth Rowing Team, both sexes, aged 19-23. Each time, before starting the exercise test, a non-invasive anthropometric analysis will be performed using the TANITA MC-780MA body composition analyzer (tanita Japan), to determine the body composition: percentage of body fat, body fat mass, lean tissue mass, muscle mass, body water and body mass index (BMI). On the three indicated dates, before and after the stress test, capillary blood (ear lobe) from the cubital vein will be collected from the participants. Using immunoenzymatic ELISA tests, the following will be determined: EPO (erythropoietin), VEGF (vascular endothelial growth factor), CRP (C-reactive protein), glycogen, hypoxanthine (Hx). Glucose level will be determined using an Accu-Chek Active glucometer (Roche, Germany).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • members of the Polish Youth Rowing Team - competitors officially called up to the Polish national rowing team,
  • no musculoskeletal injuries that would prevent them from performing the exercise test,
  • written consent of the competitor to participate in the study.

Exclusion Criteria:

  • anti-inflammatory drugs, other supplements in the last 3 months before starting the study,
  • failure to complete the test,
  • current injury, post-traumatic condition, illness,
