What are
Lactate Meters?
Lactate meters are handheld electronic devices used to measure the level of
lactate in the blood. They work by taking a small blood sample from the finger
or earlobe and analyzing it to determine the concentration of lactate. This
provides valuable information about an individual's lactate threshold and
anaerobic threshold during exercise.
How Lactate is Produced
When the body exercises at a high intensity, it relies more on anaerobic
respiration for energy production. During anaerobic metabolism, Lactate
Meters is produced as a byproduct. The concentration of lactate in the
blood increases proportionally to how hard and long one exercises above their
aerobic capacity. Measuring lactate levels can help indicate the body's
transition between aerobic and anaerobic energy systems.
Uses for Athletes and Coaches
Athletes and coaches use lactate testing to determine important exercise
thresholds like lactate threshold and anaerobic threshold. Knowing these
thresholds helps design effective training programs. Lactate testing allows
monitoring of progress over time to see if thresholds are improving with
training. It can guide adjustments to training intensity, duration, and
recovery periods. They are commonly used by endurance athletes in sports like
cycling, running, and swimming.
Reliability and Accuracy
For lactate testing to be useful, the lactate meter must provide reliable and
accurate readings. Most reputable brands are quite reliable, often within 5-10%
of a lab analyzer. Proper use is important, such as ensuring the test strip is
fully inserted and wiped of blood before taking the reading. Newer meters have
improved in getting close to a true blood lactate level from just a few drops
of blood. Regular calibration using control solutions helps ensure accurate
results over the life of the meter.
Determining Lactate Thresholds
There are a few main ways lactate thresholds are determined using a lactate
meter. The first is the onset of blood lactate accumulation (OBLA). This is the
exercise intensity where blood lactate begins to rise above resting levels,
around 1-2 mmol/L. The second threshold is individual anaerobic threshold
(IAT). This occurs at around 2-4 mmol/L and marks the transition point where
lactate production exceeds clearance by the body. The highest lactate reached
during a workout, known as peak lactate, also provides useful
performance-related information. Tracking these thresholds over time shows
adaptations from training.
Maximizing Training Effectiveness
By determining lactate thresholds, athletes can periodize their training to
target the appropriate energy systems. Workouts below the lactate threshold
focus on improving aerobic capacity, while those above target anaerobic
abilities. Strategically alternating these allows both energy systems to
progress. Peaking workouts just below or at lactate threshold pace help prepare
for race intensity and delay fatigue. Lactate testing ensures training stress
is optimally stimulating adaptations without overreaching. It equips athletes
and coaches with the information needed to continually maximize training effectiveness
and athletic performance.
Alternative Methods for Athletes
While lactate meters are a proven method, alternatives exist that do not
require drawing blood. Near-infrared spectroscopy uses light to detect changes
in muscle tissue oxygenation and blood flow as a proxy for lactate changes.
Wearable devices have incorporated technology to predict lactate levels from
variables like heart rate. These non-invasive options may appeal more to some
athletes but lack the accuracy of direct blood lactate measurement. Regardless
of the approach, the goal remains using exercise intensity thresholds to
enhance training programs in a periodized manner.
In lactate meters provide athletes and coaches an objective way to monitor
lactate thresholds and optimize training intensity. When used correctly over
time, they equip individuals with valuable physiological data to continually
progress their aerobic and anaerobic capacities. While more alternatives are
emerging, lactate meters remain the gold standard approach for determining
lactate thresholds essential for building peak sports performance.
