Lactate-scout-4-lancate-analyzer-for-athletes-2

Key features


Simple, accurate and reliable lactate analyzer for sports


Lactate Scout 4 is the first choice of sports medicine and sport professionals around the world for the easy and reliable measurement of lactate whilst training out on the track, working hard in the gym or analyzing performance in the laboratory.

Lactate Scout 4 has been ergonomically designed to be effectively used in the field as a training companion for coaches and athletes to determine optimum training programs, define training zones, and avoid inefficient training exercises.

 

This hand-held lactate analyzer requires just 0.2 µl of capillary blood and returns results in 10 seconds. Up to 500 results can be stored on the device which also features, easy connection to heart rate monitors and a stopwatch function to aid in performance measurement. The features of Lactate Scout 4, such as the integrated step test function and Bluetooth connectivity, make it the most advanced lactate meter in the market.

 

The intuitive and simple interface on the Lactate Scout 4 allows for easy navigation on the e-paper display ensuring excellent readability under changing light conditions and viewing angles.

Lactate messurement uses in sport performance


During endurance exercises such as long-distance running and cycling, when the demand for energy is high, lactate is produced faster than the ability of the tissues to remove it. As a result, lactate concentration in the blood begins to rise.

 

In fitness, sports, and cardio-rehabilitation measuring lactate is supportive to define training intensities for maximum fat catabolism, increases in endurance, and avoid critical over-exhaustion.

 

Lactate is produced when the muscles use carbohydrates to create energy for exercise. The underlying metabolic process is the glycolysis. It happens continuously but increases when energy demand is high for a prolonged period of time and availability of oxygen to the cells is limited.

 

Increased glycolysis produces hydrogen ions and lactate, and it's the hydrogen ions that cause pain, sore muscles, cramps and fatigue. The body protects itself by telling you: "I can't do this anymore".

 

Regular endurance sports should only take place within the respective 'lactate steady-state' - a well-balanced relationship between lactate production and elimination.

 

Lac [blood] = Lac [produced] ­ Lac [eliminated]

With higher exercise intensity the lactate level in the blood reaches the anaerobic threshold or the onset of rapid blood lactate accumulation. This point can be determined in step tests with increasing training intensity in defined intervals e.g. on a tread-mill, bicycle or in a field test. The higher the level of effort is when the rise of lactate indicates the anaerobic threshold the better is the performance status of the athlete.

Intense training teaches the body to use lactate as a source of fuel on a par with the carbohydrates stored in muscle tissue and the sugar in blood. Athletes increase their lactate threshold by training which means their blood lactate increases later and at higher intensities.
