Key result
Post-exercise acupuncture may increase lactate removal versus sham without affecting heart rate.
Why the study?
Intense exercise causes lactate accumulation that drives muscle fatigue, and recovery is critical when athletes compete multiple times daily, but the immediate effects of acupuncture on lactate removal after exercise were unclear.
Does real acupuncture improve lactate removal after intense physical exercise in exercising individuals?
Does real acupuncture improve lactate removal after intense physical exercise in exercising individuals?

Pilot data too limited for practice; leaves open whether acupuncture aids post-exercise lactate removal.
The recovery process is of utmost importance in activities where the athlete has to compete more than once a day during the competition. It is generally accepted that intense physical activity results in lactate production and the accumulation of lactate in exercising muscle is considered one of the main determining factors of fatigue. The main goal of this pilot study was to evaluate the immediate effects of acupuncture on lactate removal after just one treatment session and to evaluate lactate, heart rate, and oxygen saturation behavior at 5, 30, and 60 min after exercise. Four individuals were evaluated and were part of both the experimental group (real acupuncture) and the placebo group (sham acupuncture) and were tested at two distinct times with a one-week interval. Baseline values of lactate, heart rate, and oxygen saturation were measured, and then the participants performed a warm-up and subsequently completed the Wingate test. The individuals were re-evaluated 5, 30, and 60 min after the Wingate test, and either real or sham acupuncture was applied after the test. After the intervention period, there was an increased ability to reduce or remove lactate after maximum effort. No significant differences were observed in heart rate or oxygen saturation. Conclusions: The results of this case study seem to suggest that acupuncture has a positive effect on lactate removal after intense physical exercise. El proceso de recuperación es de suma importancia en aquellas actividades en las que el atleta tiene que participar más de una vez al día durante la competición. Está generalmente aceptado que la actividad física intensa origina una producción de lactato, cuya acumulación en el músculo es considerada uno de los principales factores que determinan la fatiga. Objetivo: El objetivo principal de este estudio piloto fue evaluar los efectos inmediatos de la acupuntura en la eliminación de lactato tras una sesión terapéutica, y evaluar el lactato, la frecuencia cardiaca y el comportamiento de la saturación de oxígeno transcurridos 5, 30 y 60 minutos del ejercicio. Se evaluaron cuatro individuos, que formaron parte tanto del grupo experimental (acupuntura real) como del grupo placebo (acupuntura sham), realizándose la evaluación en dos momentos distintos, con una semana de intervalo. Se midieron los valores basales de lactato, frecuencia cardiaca y saturación de oxígeno, seguidamente los participantes realizaron un calentamiento, y posteriormente completaron la prueba Wingate. Se reevaluó a los individuos transcurridos 5, 30 y 60 minutos tras la prueba Wingate aplicándose, bien acupuntura real o acupuntura sham tras la misma. Tras el periodo de intervención, se produjo un incremento de la capacidad de reducción o eliminación del lactato tras un esfuerzo máximo. No se observaron diferencias significativas en cuanto a frecuencia cardiaca o saturación de oxígeno. Los resultados de este estudio de caso parecen sugerir que la acupuntura tiene un efecto positivo en la eliminación de lactato tras el ejercicio físico intenso.

Carpinteiro et al. (2023) studied Healthy individuals undergoing intense physical exercise (n=4). Real acupuncture vs. Sham acupuncture was evaluated on Lactate removal, heart rate, and oxygen saturation behavior at 5, 30, and 60 min after exercise. Acupuncture applied after intense physical exercise increased lactate removal compared to sham acupuncture in a pilot study of 4 individuals, with no significant differences in heart rate.
