Behind the scenes footage from Liverpool FC TV (LFCTV) shows the first team using the EKF Diagnostics Biosen C-Line analyzer as part of their pre-season lactate threshold testing program.

Liverpool players were put through their paces in training ahead of the new season after taking part in a 'lactic acid' test - and not-so-surprisingly, Doiminic Solanke and James Milner came out on top.

Liverpool players were instructed to jog around the pitch and after completing a lap, had a blood sample taken. If the level of lactic acid in their blood exceeded a certain amount, they were out of the drill.

Testing and training to improve lactate threshold is one of the most common and effectively used performance markers used by many football teams and coaches. It is widely used as a fitness marker in endurance sport and football in Europe, so it’s no surprise that coaches such as Klopp are incorporating these practices in the Premier League. The point is to learn the highest intensity at which a footballer can train or compete before hitting the wall from high levels of blood lactate. Football teams know that one of the keys to success is to increase sustainable power and speed while playing at lactate threshold.



Lactate threshold, or Lactate inflection point (LIP), can be defined as “the exercise intensity at which the blood concentration of lactate and/or lactic acid begins to exponentially increase”1.

Once you surpass this threshold, lactic acid will start to build up in your muscles faster than your body can remove it, eventually leading to fatigue.

Testing and improving lactate threshold within a training program can be used to make stronger and faster athletes. If the pace and work rate a footballer can maintain at your lactate threshold is higher than that of your competitor then over the course of 90 minutes you go faster, get back in position quicker, make hard yards towards the end of the game and win!

The Biosen C-Line glucose and lactate analyzer is the perfect solution for sports clubs and institutions looking for a lab accurate method of testing lactate in a point-of-care setting.
