This study, Influence of IMT on Ventilatory Efficiency & Cycling Performance in Normoxia and Hypoxia, is published in Frontiers in Physiology. The aim of the study is to analyse the influence of inspiratory muscle training (IMT) on ventilatory efficiency in normoxia and hypoxia. It also investigates the relationship between ventilatory efficiency and cycling performance. The point of the study The premise of the study is that IMT improves ventilatory efficiency in normoxia and hypoxia. It also reduces the metabolic demands of the respiratory muscles in both conditions. The study also hypothesizes that improvements in submaximal cycling performance can be linked to improvements in ventilatory efficiency in normoxia and hypoxia. Study method The study assigns participants, at random, to either a control group or an inspiratory muscle training (IMT) group. The IMT group were to complete 30 inhalations twice a day using the POWERbreathe K3. They were to do this 5 days a week for 6 weeks. Researchers set the POWERbreathe K3 to 50% of each participant’s Pimax (maximal inspiratory mouth pressure). By contrast, the control group did not perform any IMT. To determine Pimax participants had to inspire through the K3 as quickly as possible. And in order to achieve a stable measurement they were perform this a few times. Conclusions for training at altitude The study suggests a possible positive effect of IMT on cycling time trial performance in both normoxic and hypoxic conditions. It also shows that hypoxia has a negative effect on ventilatory efficiency. It furthermore shows that IMT may reduce this effect. Additionally the authors report that these findings may have relevance for athletes planning to train at a high altitude, or compete at high altitude. Finally, the study suggests that Inspiratory Muscle Training before a competition at altitude might be a successful method to improve performance. £675.00 K5 IMT Rated 5.00 out of 5 based on 1 customer rating Add to basket £599.00 K4 IMT Rated 5.00 out of 5 based on 1 customer rating Add to basket £550.00 K3 IMT Rated 5.00 out of 5 based on 2 customer ratings Add to basket
