Immediate Effects of an Inverted Body Position on Energy Expenditure and Blood Lactate Removal after Intense Running

Abstract

We compared the immediate effects of a cool-down strategy including an inverted body position (IBP: continuous 30-s alternations of supine and IBP) after a short period of an intense treadmill run with active (walking) and passive (seated) methods. Fifteen healthy subjects (22 years, 172 cm, 67 kg) completed three cool-down conditions (in a counterbalanced order) followed by a 5-min static stretch on three separate days. Heart rate, energy expenditure, blood lactate concentration, fatigue perception, and circumference of thighs and calves were recorded at pre- and post-run at 0, 5, 10, 20, and 30 min. At 5 min post-run, subjects performing the IBP condition showed (1) a 22% slower heart rate (p < 0.0001, ES = 2.52) and 14% lower energy expenditure (p = 0.01, ES = 0.48) than in the active condition, and (2) a 23% lower blood lactate than in the passive condition (p = 0.001, ES = 0.82). Fatigue perception and circumferences of thighs and calves did not differ between the conditions at any time point (F10,238 < 0.96, p < 0.99 for all tests). IBP appears to produce an effect similar to that of an active cool-down in blood lactate removal with less energy expenditure. This cool-down strategy is recommended for tournament sporting events with short breaks between matches, such as Taekwondo, Judo, and wrestling.

Changes in Heart Rate, Muscle Temperature, Blood Lactate Concentration, Blood Pressure, and Fatigue Perception Following Jogging and Running: An Observational Study

“…It is important to know cardiovascular response, muscle temperature, and physiological and psychological fatigue when planning and determining the parameters of warm-up methods (e.g., mode, duration, and intensity). Up to date, there have been numerous studies [6][7][8][9][10] reporting the changes following various warming-up on aforementioned outcomes. Although the data from these studies are valuable, the body's immediate responses following the most popular modes of warm-up, jogging and running, are not fully understood.…”

“…On arrival to the laboratory, subjects laid in a prone position on a treatment table and rested for 10-minute to achieve stability of the autonomic nervous system [7] and to attach the heart rate monitor and temperature probe. While in this position, a heart rate monitor (sampled at 60 Hz; Polar Beat, Polar Electro Inc., New York, USA) was applied to the chest.…”

“…From the average results of this study, the 0-5 minute recovery was 7.75 mMol/L, so the anaerobic threshold level had been exceeded. Lactic acid occurs when the number of H+ atoms exceeds the body buffering system, or in other words, a decrease in body pH causes muscle pain and reduces performance (Garbouj et al, 2016) (McMillan et al, 2005 (Kim & Park, 2020). Decreased performance can be caused by two factors, namely metabolic factor, and muscle fatigue.…”

“…Thus, physiological and psychological recoveries after training are important for health and optimal performance. Kim and Park [7] studied the effect of a cool-down strategy with an inverted body position (IBP) on fatigue perception, blood lactate concentration and heart rate in 22 athletes. While the fatigue perception was not significantly modified by this recovery technique, blood lactate level and energy expenditure were significantly lower than in controls, suggesting that this technique could be useful in many disciplines that have short breaks during matches, such as martial arts and wrestling.…”
