Capillary blood samples were drawn from puncturing the earlobe to measure [La−] and urea. [La−] was evaluated using 15 μl of blood and 30 μl of EDTA in Yellow Springs® 2300 Lactimeter (YSL, Cleveland, OH, USA) before each intervention, immediately after each round, and at minutes three, five, and seven after the completing the protocol. These samples were used to identify the kinetics and peak of [La−]. Urea was measured by analyzing 32 μl of capillary blood before and after the training sessions using a portable analyzer through reflectance photometry (Reflotron Analyser®; Boehringer-Mannheim, Lyon, France). All procedures followed the manufacturer’s recommendations.
Reflotron analyser
Manufactured by Roche
Sourced in France
The Reflotron Analyser is a compact, automated clinical chemistry analyzer designed for rapid and reliable analysis of various analytes in small sample volumes. It utilizes reflectance photometry technology to measure the concentration of different substances in blood, urine, or other bodily fluids. The Reflotron Analyser is a versatile instrument capable of performing a wide range of tests, including those for glucose, cholesterol, triglycerides, and liver function, among others.

Thirty minutes after each training session, the players were asked to provide an RPE rating, using the modified CR10-scale by Foster [11] (link). All players were familiarized with the RPE scale prior to the commencement of the study. Players were prompted to track their RPE individually using a customdesigned application on a portable computer tablet. Each player selected their RPE rating by touching the respective score on the tablet, which was then automatically saved to the player's profile. This method helped minimise factors that could influence a player's RPE rating, such as peer pressure and replicating other players' ratings [43] . Each individual RPE value was multiplied by the session duration to generate a session-RPE (s-RPE) value [12] (link)[13] [14] .
Forty-eight hours before the matches, we measured the concentration of plasma CK found in each player [7] . To accomplish this, the skin was first cleaned using a 95% ethyl alcohol. After drying, 32 μL of capillary blood was collected using an automatic lancet. The blood was saved in a heparinized capillary tube (Reflotron Plus, Roche Diagnostics) and immediately pipetted onto a reactive CK strip (Reflotron Plus, Roche Diagnostics), to be placed in a Boehringer Mannheim Reflotron Analyser®.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
