“…In stark contrast to the findings of Chiappa et al (3,4), we observed no effect of ITL upon lactate recovery kinetics. The novel finding of this investigation is that following IMT, ITL accelerates the capacity for whole body lactate exchange and clearance.…”

“…clearance by a similar magnitude to that achieved with an active recovery involving locomotor muscles, but with the benefit of sparing intramuscular energy stores (6). Given that lactate consumption and / or reduced production by the inspiratory muscles is enhanced by training (23,35,38) it is attractive to speculate that the finding of Chiappa et al (3) would be magnified after RMT and this was the focus of the present study. we quantified the contribution of associated physiological variables to the regulation of plasma acid-base homeostasis using the integrated physicochemical approach.…”

Purpose: To investigate the effects of inspiratory muscle loading (ITL) and inspiratory muscle training (IMT) upon blood lactate concentration ([lac -] B ) and acid-base balance following maximal incremental cycling.Methods: 18 subjects were divided into a control (n=9) or IMT group (n=9). Prior to and following a 6 wk intervention subjects completed two maximal incremental cycling tests followed by 20 min of recovery with (ITL) or without (passive recovery; PR) a constant inspiratory resistance (15 cmH 2 O). The IMT group performed 6 wk pressure threshold IMT at 50% maximal inspiratory mouth pressure (MIP). Throughout recovery, acid-base balance was quantified using the physicochemical approach by measuring the strong ion difference

“…Muscle and blood lactic acid accumulation have long been related to impaired exercise performance (Hill et al 1924) and several strategies have been used to alleviate the physiological and subjective burdens associated with increased lactic acidemia (Chiappa et al 2008b). The subject is of special concern when the lactic-glycolytic metabolic pathway is heavily requested for ATP regeneration, such as during short-term maximal-intensity exercise, e.g., the 30-s, all-out Wingate test (Dotan 2006).…”

“…Therefore, it is conceivable that increased respiratory muscle work with inspiratory resistive loading (IRL) could accelerate postWingate blood lactate (Lac b -) removal. Indeed, we have recently shown that post-exercise Lac -clearance was significantly increased by adding IRL to passive leg recovery from maximal incremental exercise test in healthy individuals (Chiappa et al 2008b). In that specific study, however, we did not address whether this strategy would actually be able to improve performance on subsequent exercise.…”

We have previously shown that post-exercise inspiratory resistive loading (IRL) reduces blood lactate ([Lac(b)(-)]). In this study, we tested the hypothesis that IRL during recovery could improve subsequent exercise performance. Eight healthy men underwent, on different days, two sequential 30-s, cycle ergometer Wingate tests. During the 10-min recovery period from test 1, subjects breathed freely or through an inspiratory resistance (15 cm H(2)O) with passive leg recovery. Arterialized [Lac(b)(-)] values, perceptual scores (Borg), cardiac output by impedance cardiography (QT), and changes in the deoxygenation status of the M. vastus lateralis by near-infrared spectroscopy (DeltaHHb), were recorded. [Lac(b)(-)] was significantly reduced after 4 min of recovery with IRL (peak [Lac(b)(-)] 12.5 +/- 2.3 mmol l(-1) with free-breathing vs. 9.8 +/- 1.5 mmol l(-1) with IRL). Effort perception was reduced during late recovery with IRL compared with free-breathing. Cardiac work was increased with IRL, since heart rate and QT were elevated during late recovery. Peripheral muscle reoxygenation, however, was significantly impaired with IRL, suggesting that post-exercise convective O(2) delivery to the lower limbs was reduced. Importantly, IRL had a dual effect on subsequent performance, i.e., improvement in peak and mean power, but increased fatigue index (P < 0.05). Our data demonstrate that IRL after a Wingate test reduces post-exercise effort perception and improves peak power on subsequent all-out maximal-intensity exercise.

“…Inspiratory muscle training enhances pulmonary O 2 uptake kinetics and high-intensity exercise tolerance in humans, since it seems to increase leg blood flow to the exercising limbs (21). Indeed, several studies have reported that, after a specific training of inspiratory muscles, blood lactate concentration is reduced to a certain exercise intensity, which has been partly attributed to an improved ability of inspiratory muscles to metabolize lactate (51,52). IMT, therefore, appears to have considerable potential for exercise performance in athletes.…”

-Piñero J. Effects of a nasal ventilator restriction device on lung ventilation and gas exchange during exercise in healthy subjects. Nutr Hosp 2016;33: [444][445][446][447][448][449][450] Effects of a nasal ventilator restriction device on lung ventilation and gas exchange during exercise in healthy subjects ResumenIntroducción y objetivos: un dispositivo llamado FeelBreathe ® (FB) se ha diseñado, desarrollado y patentado para el entrenamiento de la musculatura inspiratoria (IMT). Para examinar los efectos de FB en la ventilación pulmonar y el intercambio gaseoso durante el ejercicio, se tomaron medidas de 27 voluntarios varones sanos entrenados (edad: 32,5 ± 7,2 años). Métodos: al inicio del estudio se midieron tanto la presión inspiratoria máxima estática (PIM) y la capacidad pulmonar mediante espirometría. Seguidamente, se realizó un test incremental en cicloergómetro para determinar el VO 2 pico. Cada sujeto, tres días más tarde, realizó aleatoriamente tres pruebas idénticas submáximas en cicloergómetro a una intensidad comprendida al 50% entre los umbrales ventilatorios bajo tres condiciones de respiración diferentes: a) respiración oronasal (ONB), b) respiración nasal (NB) y c) la respiración nasal a través del FB. Resultados: la prueba con FB mostró una ventilación minuto (VE) y una frecuencia respiratoria (BF) inferior que en las pruebas de NB, la cual a su vez tenía menor BF, pero similar VE que ONB (p < 0,001). A pesar de esto, FB obtuvo valores similares de VO 2 , cociente respiratorio (RER), frecuencia cardiaca (HR) y saturación de oxígeno capilar periférica (SpO2) en comparación con NB y ONB. Esto último puede ocurrir debido en parte al aumento del volumen tidal (VT) y el tiempo de expiración (Tex) en FB hasta el mismo nivel que en la prueba de NB, los cuales fueron un 15% y 14% en ambas pruebas, respectivamente, superiores a ONB (p < 0,001). El porcentaje de tiempo de inspiración (Ti/Tot) fue 7% mayor en la prueba de FB en comparación con NB y ONB (p < 0,001). Solamente en la prueba de FB se encontró un aumento de la presión final de la espiración de CO 2 (P ET CO 2 ) y la reducción de la presión final de la espiración de O 2 (P ET O 2 ) y la fracción de expiración de O 2 (FEO 2 ). Conclusiones: FeelBreathe es un nuevo dispositivo de restricción nasal que estimula los músculos inspiratorios para producir un patrón de respiración más eficiente durante el ejercicio en los seres humanos bien entrenados. AbstractIntroduction and objectives: A device called FeelBreathe ® (FB) has been designed, developed and patented for inspiratory muscle training (IMT). In order to examine the effects of FB on lung ventilation and gas exchange during exercise, 27 trained male healthy volunteers (age: 32.5 ± 7.2 years) were measured. Methods: Maximum static inspiratory pressure (PI max ) and spirometry to determine lung capacity were measured at baseline. We continued with an incremental cycloergometer to determine the VO 2 peak. Three days later, each subject performed randomly three identical submaximal cycloergome...

Blood Lactate during Recovery from Intense Exercise

Abstract: These data are consistent with the notion that inspiratory muscles may be net consumers of lactate during recovery from intense exercise.
