Clinical Trial Summary

Physical exercise induces numerous changes in the body in a complex signalling network caused by or in response to increased metabolic activity of contracting skeletal muscles. The application of omics analytical techniques such as proteomics and metabolomics in the field of sport allows us to understand how the human body responds to exercise and how sports results can be improved by optimising nutrition and training. Both omics techniques offer a quantitative measurement of the metabolic profiles associated with exercise and are able to identify metabolic signatures of athletes from different sports disciplines. Basketball is a high-intensity exercise modality interspersed with low-intensity. The performance requirements of basketball include aerobic and anaerobic metabolism, with anaerobic metabolism being considered the main energy system. Therefore, basketball players need great athletic ability to produce a successful performance during competition. For optimal sports performance it is important to adjust the training load, i.e. the degree of effort that the player can withstand in a single training session. Coaches require effective and objective load monitoring tools that allow them to make decisions about training plans based on the needs of each player. Microsampling systems emerge as an alternative to venipuncture by facilitating self-sampling, which can be carried out outside healthcare centres, in a comfortable and precise way from a small finger prick that the user can perform. These systems are less expensive and can be effective in measuring the levels of glucose metabolism products, such as lactate, through the application of metabolomics and proteomics. On the other hand, the use of non-invasive methods of measuring lactate levels is becoming increasingly popular in sports medicine. The use of saliva as an alternative fluid to the blood shows promise for identifying the concentrations of metabolites that occur during and after sports training.


Description:

The study hypothesizes that the use of minimally invasive microsampling systems, and subsequent application of metabolomics and proteomics, will allow the detection of differences in the levels of lactate and other metabolites and proteins produced by the greater energy demand of the musculoskeletal system after a single collective training on the court, in federated basketball players. In addition, lactate levels will be correlated with the subjective sensation of perceived exertion. The main objective of the study is to apply metabolomics techniques to analyze lactate levels in capillary blood samples collected by a dried blood spot (DBS) microsampling device, and to study their correlation with the subjective sensation of perceived effort in federated basketball players before and after performing a single collective training session on the court. The secondary objectives of the study are to measure the change in lactate levels in capillary blood samples collected by a DBS device, and in saliva samples collected by a collector, before and after performing a single collective training on the court. In addition, in these samples, the change in the levels of other metabolomic and proteomic markers related to energy, lipid and amino acid metabolism will be measured. The correlation between salivary and blood lactate levels will also be studied; subjective sensation of perceived exertion and salivary lactate levels; the subjective sensation of perceived exertion and the levels of other metabolomic and proteomic markers will be also studied. A single-group quasi-experimental (or pre-post) study will be carried out on 70 basketball players between the ages of 18 and 40. Each participant will attend 2 visits to the sports facilities of their basketball club: - A recruitment and pre-selection visit (to check the eligibility criteria and sign the informed consent). If the inclusion criteria are met, will be scheduled to: - A single study visit on the same day agreed for training. The main variable of the study is the correlation between lactate levels, measured in capillary blood pre- and post-training, and the subjective sensation of perceived effort.

Outcome

Type Measure Description Time frame Safety issue
Primary Correlation between blood lactate levels and the subjective sensation of perceived effort Lactate concentration (µM) measured in capillary blood pre- and post- training. Four drops of capillary blood will be collected pre- and post-training by means of a puncture with a retractable lancet on the index, middle or ring finger, and deposited on a dried blood spot (DBS) "HemaXis DB10" card for analysis.
The subjective sensation of perceived effort will be assessed with the Perceived Exertion Index (RPE) measured post-training. This tool is used to monitor perceived effort during sports practice. It consists of a graduated scale from 0 to 10 where 0 is rest and 10 is maximum perceived effort.

Secondary Pittsburgh Sleep Quality Index It is a validated scale that measures the usual sleep habits during the past month. It consists of 7 areas: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleep medication, and daytime dysfunction. It contains a total of 19 items, grouped into 10 questions where each of the areas evaluated is scored between 0 and 3. The scores from the seven areas are finally added up to give an overall score. The component scores are summed to produce a global score (range 0 to 21). Higher scores indicate worse sleep quality. Pre-training (baseline)
