‘Dry, cold air can be damaging to the airways because the nose can’t do its normal job of warming/humidifying,’ says Dickinson. This can cause problems, especially in winter. Although this delivers more air to your lungs, there is a downside: When you nose-breathe at rest, air is warmed and humidified by your nose, but breathing through your mouth during exercise bypasses this process. At rest, you breathe primarily through your nose, but very soon into a run ‘you switch to mouth breathing, as it’s the easiest way to draw in air’, says Dickinson. If you’re paying attention as you start to run you’ll notice a shift in how you breathe. ‘This means that the shift between rest and producing enough energy aerobically will be quicker, so the breathless discomfort that comes at the beginning of a run will be over with more quickly.’ ‘The fitter you get, the quicker your oxygen kinetics will kick in at the beginning of a run,’ says Dickinson. Managing your early effort to allow your system the time to kick in is particularly important if you’re a new runner, or rebuilding your fitness after a layoff. ‘Starting slowly is key to allowing these processes to build up, rather than shocking the system,’ says Paul Hough, Lead Sport and Exercise Scientist at St Mary’s University Sports Performance Service. #Achilles locked heart how to#‘It knows when you’re about to exercise, so you’ll unconsciously start breathing slightly faster and more deeply, and capillaries will start to dilate in anticipation of carrying more oxygen.’Īs you set off, you need to consider how to help this natural response work effectively. ‘Your respiratory centre is found in an area of the brain called the hypothalamus,’ says Dr John Dickinson, Head of the Respiratory Clinic at the University of Kent.
