Abstract

The objective of this study was to elucidate the effects of myofascial decompression through cupping therapy (CT) on running economy (RE) in well-trained runners. Five minutes of CT or placebo gel (PG) was applied to bilateral hip extensor muscles of 15 well-trained runners (n = 7 female, n = 8 male) after a 10-minute treadmill warm-up. Running economy was measured using two 6-minute steady-state treadmill runs, one at a standardized velocity (females = 3.93 m·s-1; males = 4.47 m·s-1) and the other at 10-km race velocity. Maximal oxygen consumption (VO2 max) test followed the RE tests. All subjects performed both conditions in randomized order. Running economy, respiratory exchange ratio (RER) during steady-state, and VO2 max after CT and PG were compared independently using paired two-sample t-tests. Effect size for all variables was calculated using Cohen’s d. There was no difference in RE expressed as %VO2 max between CT and PG (standard = 76.9 ± 10.6% of VO2 max vs. 76.6 ± 10.5% of VO2 max, p = 0.72, d = 0.02; 10-km = 84.2 ± 7.2% of VO2 max vs. 83.7 ± 6.9% of VO2 max, p = 0.17, d = 0.07). There was also no difference in VO2 max between CT and PG (65.1 ± 9.1 mL.kg-1.min-1 vs. 65.0 ± 10.3 mL.kg-1.min-1, p = 0.96, d = 0.004); however, RER was significantly increased by CT compared to gel (standard = 0.92 ± 0.06 vs. 0.90 ± 0.04, p = 0.04, d = 0.32; 10-km = 0.94 ± 0.04 vs. 0.92 ± 0.03, p = 0.02, d = 0.52). Acute CT increases steady-state carbon dioxide expiration in well-trained runners without changing oxygen consumption. This has implications for enhanced buffering from putative increased localized blood.
