STUDY 'Functional' inspiratory and core muscle training enhances running performance and economy Tong, Tomas K.; McConnell, Alison K.; Lin, Hua; Nie, Jinlei; Zhang, Haifeng; Wang, Jiayuan Abstract "We compared the effects of two 6-week high-intensity interval training interventions. Under the control condition (CON), only interval training was undertaken, whilst under the intervention condition (ICT), interval training sessions were followed immediately by core training, which was combined with simultaneous inspiratory muscle training - 'functional' IMT." Conclusion "Compared to CON, the ICT group showed larger improvements in SEPT (sport-specific endurance plank test performance), running economy at the speed of the OBLA, and 1-hr running performance (3.04% vs 1.57%, P<0.05)… …Such findings suggest that the addition of inspiratory-loaded core conditioning into a high-intensity interval training program augments the influence of the interval program upon endurance running performance, and that this may be underpinned by an improvement in running economy."
