简要总结
This observational study aims to evaluate multilevel physiological, molecular, metabolic, intestinal, immunological, and psychophysiological responses to rowing-specific exercise in elite rowers. The study is designed to investigate how maximal and prolonged rowing ergometer exercise influences integrated adaptive mechanisms related to mitochondrial function, metabolic regulation, intestinal permeability, immune activation, DNA damage response, and psychological status.
Thirty members of the Polish Youth National Rowing Team, aged 19-24 years, will participate in the study during two different training periods. During the competitive phase, participants will perform a 2000-m maximal rowing ergometer test, whereas during the preparatory phase they will complete a 6000-m rowing ergometer test. Blood samples and physiological measurements will be collected before exercise, immediately after exercise, and after 1 hour of recovery.
The study will assess gene expression, circulating biomarkers, flow cytometry parameters, blood morphology, lactate concentration, continuous glucose monitoring data, wearable metabolic sensor measurements, nutritional status, and psychological responses. The primary objective is to identify integrated biomarkers reflecting exercise load, recovery dynamics, and adaptive capacity in highly trained athletes. The study also aims to improve understanding of the interaction between metabolic, mitochondrial, intestinal, immunological, and psychophysiological responses to intensive exercise in rowing.
详细描述
This study is designed to investigate integrated physiological, molecular, metabolic, intestinal, immunological, and psychophysiological responses to rowing-specific exercise in elite athletes. The study focuses on identifying biomarkers associated with exercise load, early recovery, and adaptive capacity in competitive rowers exposed to maximal and prolonged ergometer exercise.
Modern exercise physiology indicates that the response to intensive physical effort involves coordinated interactions between metabolic, mitochondrial, immune, neuroendocrine, and intestinal regulatory systems. High-intensity rowing exercise induces substantial metabolic stress, activation of mitochondrial signaling pathways, inflammatory and stress-related responses, and transient disturbances in intestinal barrier integrity. In addition, psychological factors, including mood state and pre-competition anxiety, may modulate physiological responses to exercise and recovery processes. However, previous studies have typically evaluated isolated physiological or biochemical markers without integrating molecular, cellular, and psychophysiological responses within a rowing-specific exercise model.
The study will include 30 competitive rowers, members of the Polish Youth National Rowing Team, aged 19 to 24 years, of both sexes. Assessments will be performed during two distinct phases of the annual training cycle. During the competitive phase (May-June 2026), participants will complete a 2000-m maximal rowing ergometer test. During the preparatory phase (November 2026), participants will perform a 6000-m rowing ergometer test. Both exercise protocols are routinely used within elite rowing training and performance monitoring.
Blood samples and physiological measurements will be collected at three time points during each testing session: before exercise (baseline), immediately after exercise, and after 1 hour of recovery. Venous blood samples will be used for hematological, biochemical, molecular, and flow cytometric analyses. Capillary blood samples will be collected for lactate assessment.
The study includes several integrated research modules:
