Abstract

Studies have demonstrated the positive effects of acupuncture on athletic performance. The aim of this study was to determine the acute effects of acupuncture on heart rate, the perceived exertion scale and lactate levels in recreational athletes. Fifteen competitive males engaged in HIIT. The characteristic was 29.86±2.51 years old, heart rate reserve 59.00±3.33, lactate 3.17±0.50 mM/DL. The subjects were submitted to two exercise sessions. Both training sessions consisted of 10 burpees, 12 thrusters and 14 box jumps (75 cm high) for 12 minutes. Activity intensity was between 85 and 95% of maximum heart rate. Acupuncture points: ST36, L3, LI11. The student’s t-test was adopted, Shapiro-Wilk test was applied for normality, and Pearson correlation. There was a positive correlation of r = 0.69 between lactate levels and heart rate. Lactate: Lac1 15.00±1.18 – Lac2 19.59± 1.46 p= 0.0001*; Heart 1rate: HRF 163.71±7.27 – HRF2 177.60±6.99 p=0.0001*; Blood pressure: SBP1 174.86±1.57 – SBP2 180.86±1.77 p= 0.0001*; PES1: 19.4±1.14; PES2 16.8±0.84 p= 0.0001*; weight1 – 182,57±12,05; weight 2 206,43±11,39 p=0.0325*. Acupuncture increased lactate accumulation, heart rate and blood pressure, suggesting that the exertion reached after acupuncture is higher than without acupuncture. The acupuncture technics improved the athlete performance.

Comment: The manuscript entitled Acupuncture on Lactate, Perceived Exertion in Recreational Athletes Submitted to HIIT" is an excellent contribution do the academic field. Using appropriated methodology the paper carefully controlled the variables and explore the discussion regarding a new approaches for physical training. It is highly recommend to read it and use this reference for future researches using HIIT.

Comment: Dear Dr. Leonardo Mataruna, thanks for tour comments. It's our worry produce a worthy and confiable methodology to turn acupuncture as technique to improve better performance.

Comment: Does increased lactate and heart rate for the same workload/intervals show increased performance? I'm not sure if I understand that conclusion.

Comment: Dear O' Dowd-Hill
Thanks for your questions, Yes the technics of Acupuncture allowed the volunteers perform better, it hapend because the technic improve higher levels of blood on muscles involved, the Acupuncture is a invasive it stimulate nitric oxide relaxing vassels. Another explanation, the vagal sistem was stimulated improving left ventricular contraction.
I hope answer help you understand the process of increase lactate a heart rate frequency
