Blood creatine phosphokinase level as a recovery criterion in professional soccer players during the competition period
Monitoring CK levels can help identify early signs of muscle overload. A rise in CK may serve as an indicator for adjusting training loads and supporting injury-risk reduction.
The device technology is used on the International Space Station (ISS), reflecting its suitability for environments where precision, reliability, and system stability are especially important.
Lab-on-a-chip technology enables quantitative analysis from a small sample volume, with rapid results and strong data reproducibility.

Early detection of overload signals may help reduce the risk of muscle injuries and optimize recovery times, with a potential positive impact on a club's financial management.
A club incurs direct financial losses when a player is sidelined, even for a short time. The value of the sporting asset declines, while salary obligations remain unchanged.
Monitoring CK and other biomarkers can help detect overload earlier, adjust the training load and reduce the likelihood of muscle damage.
When a player is unavailable, the club keeps paying their salary for the entire time out.
The average recovery time for a muscle injury is 2 weeks or more.
The cost of the StarLab analyzer may be offset even with a limited reduction in days out, depending on the athlete's salary and the club's context.
The athlete's salary (point 01), paid throughout the time out (point 02), creates a direct financial loss for each injury. Multiplying this figure by the number of injuries in the season gives an estimate of total losses. Klinogicare® StarLab is designed to provide objective data that can help the medical team better manage the athlete's risk and availability.
Example: with a monthly salary of $80,000 and 5 injuries per season, total losses amount to $200,000.
Periodic biochemical monitoring can help teams move from reactive decisions to proactive risk management, which may contribute to fewer injuries and improved sports performance.

CK, AST, LDH and α-HBDH help assess the degree of muscle stress and the risk of injury after intense exertion.
TP, ALB, UREA and UA provide information on protein metabolism, the quality of recovery and the risk of excessive catabolism.
K+, Na+, Cl- and CO2 reflect fluid and electrolyte balance, exercise tolerance and the risk of performance loss due to dehydration.
GLU, TG, CHOL, HDL-C and LDL-C help monitor energy availability, the lipid profile and overall metabolic adaptation.
A simple test format that uses reagents pre-applied to strips, plates, or chips.
A technology for the precise control of small liquid volumes in microscale channels with integrated processing.
For simple rapid tests, dry chemistry is sufficient. For greater precision, multi-analyte assays, and automation, microfluidics is often the preferred option.
In sports medicine, technologies that allow a more precise assessment of muscle damage and training loads are preferred.
Dry chemistry is an analytical method based on reagents pre-applied to solid surfaces such as strips, plates, or chips. When a biological sample is added (for example, a drop of blood or urine), the reagent reacts with the target components of the sample, and the result can be determined visually or with a dedicated reader.
Microfluidics is a technology based on the manipulation of very small liquid volumes (microliters and nanoliters) in microscale channels, generally on microfluidic chips. This technology can perform complex analyses on small samples by integrating different stages of the process (such as mixing, reaction, and detection) into a single device, including multi-component testing.

The article analyzes in detail the variability of CK levels in athletes, the influence of age, sex, muscle mass, type of training, and climatic conditions, as well as the clinical significance of the increase in CK after intense training.
The study carried out a comprehensive analysis of blood markers in 73 professional athletes (cyclists, team-sport athletes, and strength athletes) at three time points: after recovery, after 6 days of fatigue induction, and after 2 days of regeneration.
In cyclists, fatigue-dependent changes were observed in creatine kinase, urea, free testosterone, and IGF-1. In strength training and high-intensity interval efforts, the most pronounced and stable marker was CK.
The publication shows that muscle tissue can be damaged after intense and prolonged training under the influence of both metabolic and mechanical factors. Serum levels of enzymes and proteins are considered markers of the functional state of muscle tissue.
The most useful serum markers of muscle damage are creatine kinase, lactate dehydrogenase, aldolase, myoglobin, troponin, aspartate aminotransferase, and carbonic anhydrase CAIII.
The study analyzed the relationship between the frequency of muscle injuries, serum levels of creatine phosphokinase and urea, and the training load in professional soccer players. The retrospective cohort included 23 players from a Colombian first-division team, and the observation lasted 19 weeks.
In injured players, a statistically significant increase in CPK and urea was observed 4 weeks before the clinical manifestation of the injury, compared with their values from the previous year.
