| Title: | Acu-TENS and postexercise expiratory flow volume in healthy subjects | Authors: | Ngai, SPC Jones, YMA Hui-Chan, CWY |
Issue Date: | 2011 | Source: | Evidence-based complementary and alternative medicine, 2011, v. 2011, 726510, p. 1-7 | Abstract: | Transcutaneous Electrical Nerve Stimulation over acupoints (Acu-TENS) facilitates recovery of resting heart rate after treadmill exercise in healthy subjects. Its effect on postexercise respiratory indices has not been reported. This study investigates the effect of Acu-TENS on forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) in healthy subjects after a submaximal exercise. Eleven male subjects were invited to the laboratory twice, two weeks apart, to receive in random order either Acu-TENS or Placebo-TENS (no electrical output from the TENS unit) over bilateral Lieque (LU7) and Dingchuan (EX-B1) for 45 minutes, before undergoing exercise following the Bruce protocol. Exercise duration, rate of perceived exertion (RPE), and peak heart rate (PHR) were recorded. Between-group FEV1 and FVC, before, immediately after, at 15, 30, and 45minutes postexercise, were compared. While no between-group differences in PHR, RPE, and FVC were found, Acu-TENS was associated with a longer exercise duration (0.9 min (P=.026)) and a higher percentage increase in FEV1 at 15 and 45 minutes postexercise (3.3 ± 3.7% (P=.013) and 5.1 ± 7.5% (P=.047), resp.) compared to Placebo-TENS. We concluded that Acu-TENS was associated with a higher postexercise FEV1 and a prolongation of submaximal exercise. | Keywords: | Electrical nerve-stimulation Controlled-trial Airway response Heart-rate Exercise Acupuncture Mechanisms Electroacupuncture Individuals Resistance |
