Effects of oral supplementation of mint extract on muscle pain and blood lactate

Abstract

Study aim:To determine the effects of mint extract on muscle pain and blood lactate levels after a 400-m run. Material and methods: A group of 16 physical education students (mean age 21.81 ± 2.13 years) volunteered to participate in the study. The subjects were randomly assigned into 3 groups: mint, placebo or control. The mint group was given orally mint extract (5 ml/kg of body mass) and the placebo group was given unsweetened tea (5 ml/kg) in a double-blind fashion and cross-over design one hour before a 400-m running test. Subjects in the control group remained untreated. The effect of mint extract on muscle pain was recorded by an inquiry; blood lactate levels were measured after the running test. Results: Oral administration of mint extract significantly (p<0.01) decreased blood lactate concentrations but muscle pain levels remained unchanged in all groups. Conclusions: Oral administration of mint extract may have a beneficial effect on blood lactate clearance and therefore may increase athletic performance.

Aerobic capacity is not improved following 10-day supplementation with peppermint essential oil

“…We do not discount that peppermint may have the potential to be ergogenic, as authors have suggested some mechanisms as to how this could be achieved such as increased pain threshold (Mauskop 2001), relaxation of bronchial smooth muscle tonicity (Meamarbashi and Rajabi 2013), enhanced clearing of blood lactate (Sönmez et al 2010) or a stimulating effect on the brain (Meamarbashi 2014). The present study has its own limitations such as the relatively low sample size and single-blind design, and it also cannot be discounted that the peppermint essential oil utilised in this study may not have been as potent as in past work.…”

“…However there is also evidence that peppermint ingestion may have a benefit for sporting performance, as oral administration of peppermint essential oil has been shown to reduce blood lactate concentrations following a 400 m run (Sönmez et al 2010) and cause increments in isometric hand-grip strength (36.1%) and standing vertical jump (7.0%) performances, withn 60 minutes post-consumption (Meamarbashi 2014). Further research from Meamarbashi and Rajabi (2013) investigated the effects of 10-day peppermint essential oil supplementation (0.05 ml/day) on cardiorespiratory exercise performance.…”

“…Forced vital capacity increased by 4.8%, whilst peppermint ingestion also resulted in statistically significant reductions in resting heart rate (-4.8%) and systolic blood pressure (-6.2%). Some of the possible mechanisms for the improvements in exercise capacity could include an increased pain threshold (Mauskop 2001), relaxation of bronchial smooth muscle tonicity (Meamarbashi and Rajabi 2013), enhanced clearing of blood lactate (Sönmez et al 2010) or a stimulating effect on the brain (Meamarbashi 2014). However, the authors were unable to explain reductions in resting heart rate and systolic blood pressure.…”

The effects of peppermint on exercise performance

“…The effect of supplementation with oral peppermint extract was also studied on the perceived lower leg muscular pain and blood lactate levels one hour before a 400-m running test [12]. In this study, the peppermint had a significant effect on the blood lactate level, but not on the muscle pain.…”
