Effects Of IMT Upon Recovery Time During High Intensity, Repetitive Sprint Activity

“This study examined the influence of specific inspiratory muscle training (IMT) upon recovery time during repetitive sprint activity, as well as the physiological and perceptual responses to fixed intensity shuttle running.”

Conclusion:

“Data support existing evidence that specific IMT attenuates the blood lactate and perceptual responses to submaximal endurance exercise. In addition, the present study provides new evidence that IMT improves recovery time during high intensity, intermittent exercise in repetitive sprint athletes.”

Loading Of Trained Inspiratory Muscles Speeds Lactate Recovery Kinetics

“The purpose of this study was to investigate the effects of inspiratory threshold loading and inspiratory muscle training (IMT) on blood lactate concentration and acid-base balance after maximal incremental cycling.”

Conclusion:

After maximal exercise, inspiratory threshold loading affected lactate recovery kinetics only after IMT. Our data support the notion that the inspiratory muscles are capable of lactate clearance that increases strong ion difference [SID] and reduces plasma [H+]. These effects may facilitate subsequent bouts of high-intensity exercise.”

IMT Abolishes Blood Lactate Increase Associated With Volitional Hyperpnoea Superimposed On Exercise And Accelerates Lactate And Oxygen Uptake Kinetics At Onset Of Exercise

“The effects were examined of inspiratory muscle training (IMT) upon volitional hyperpnoea-mediated increases in blood lactate during cycling at maximal lactate steady state power, and blood lactate and oxygen uptake kinetics at the onset of exercise.”

Conclusion:

“Following the intervention, maximal inspiratory mouth pressure increased 19% in the IMT group only. Following IMT only, the increase in blood lactate during volitional hyperpnoea was abolished. In addition, the blood lactate and phase II oxygen uptake kinetics time constants at the onset of exercise and the maximal lactate steady state blood lactate were reduced. We attribute these changes to an IMT-mediated increase in the oxidative and/or lactate transport capacity of the inspiratory muscles.”

Respiratory Muscle Specific Warm-Up And Elite Swimming Performance

“Inspiratory muscle training has been shown to improve performance in elite swimmers, when used as part of routine training, but its use as a respiratory warm-up has yet to be investigated. The aim of this study was to determine the influence of inspiratory muscle exercise (IME) as a respiratory muscle warm-up in a randomised controlled cross-over trial.”

Conclusion:

“Using IME combined with a standard swimming warm-up significantly improves 100 m freestyle swimming performance in elite swimmers.”

The Effect Of IMT Upon Maximum Lactate Steady-State And Blood Lactate Concentration

“Several studies have reported that improvements in endurance performance following respiratory muscle training (RMT) are associated with a decrease in blood lactate concentration. This study examined whether pressure threshold inspiratory muscle training (IMT) elicits an increase in the cycling power output corresponding to the maximum lactate steady state.

Conclusion:

“Data supports previous observations that IMT results in a decrease in blood lactate concentration at a given intensity of exercise. That such a decrease in blood lactate concentration was not associated with a substantial (>2.5%) increase in maximum lactate steady state power is a new finding suggesting that RMT-induced increases in exercise tolerance and reductions in blood lactate concentration are not ascribable to a substantial increase in the ‘lactate threshold’.

The Influence Of Inspiratory Muscle Work History And Specific IMT Upon Human Limb Muscle Fatigue

“The purpose of this study was to assess the influence of the work history of the inspiratory muscles upon the fatigue characteristics of the plantar flexors. It was hypothesized that under conditions where the inspiratory muscle metaboreflex has been elicited, plantar flexors fatigue would be hastened due to peripheral vasoconstriction.”

Conclusion:

“The data are the first to provide evidence that the inspiratory muscle metaboreflex accelerates the rate of calf fatigue during plantar flexors, and that inspiratory muscle training attenuates this effect.”

Inspiratory Muscle Training Improves Shuttle Run Performance in Healthy Subjects

“The purpose of this study was to assess the use of computer-generated fixed-load incremental Respiratory Muscle Training (RMT) produced by the performance of repeated sustained sub-maximal inspiratory efforts with progressively reduced recovery times in healthy volunteers.”

Conclusion:

“Incremental respiratory endurance-based respiratory muscle training set at 80% of peak through range increases respiratory muscle strength, single-breath work capacity and respiratory muscle endurance and that these improvements result in reduced levels of breathlessness, an increase in predicted VO2 max and a perceived improvement in sports performance.”
