Mechanisms underlying improvements in exercise tolerance following inspiratory muscle training

This will be the 3rd seminar in a series of seminars launched by The Centre for Sports Medicine & Human Performance at Brunel University. The seminar is free and will focus on the respiratory system.

With systematic reviews and meta-analyses having confirmed that inspiratory muscle training (IMT) does improve exercise tolerance in both healthy people and people with lung and/or heart disease, the focus of research on IMT is now shifting from “if”, to “how”, exercise tolerance improves.

‘Mechanisms underlying improvements in exercise tolerance following inspiratory muscle training’ will begin with an introductory overview, by Professor Alison McConnell, of the history of IMT, the "state of the art", and the rationale for each of three putative mechanisms for the ergogenic effect of IMT. The physiology of each mechanism will be described by a leading expert in the field:

Mechanism 1

- Modulation of metaboreflex activation originating from respiratory muscles leading to preserved muscle blood flow after IMT. Dr Lee Romer, Brunel University

Mechanism 2

- Modulation of afferent feedback from respiratory muscles leading to reduced central fatigue after IMT. Dr Emma Ross, University of Brighton

Mechanism 3

- Alteration of the demand/capacity relationship of the respiratory pump in favour of capacity leading to amelioration of breathing effort after IMT. Dr Caroline Jolley, King's College, University of London.

A panel discussion of the morning’s presentations, leading to the identification and/or prioritisation of the most important research questions for IMT, and how these might be answered, closes the seminar.

The seminar will deal with the integrative physiology of the respiratory, cardiovascular, muscular and neural systems, and will consider both healthy and patient populations and will therefore be of interest to academics and post-graduate students in exercise and sports physiology, as well as clinicians working in cardiovascular and pulmonary rehabilitation.
