The template proposes a basic set of information to be provided about a dataset. Sections 1-3 provide key information about the dataset and should be completed as fully as possible; Sections 4-5 provide information for interpretation and use of the dataset, and should be completed according to your judgement. Ask yourself in completing these sections: what information would the user of this dataset need in order to be able to understand it or replicate the results? Use of the README plain text format for dataset documentation is not required, and may not be suitable for longer or more detailed documentation. In these cases, or if preferred, you can use PDF or MS Word. Information provided here must correspond accurately with information provided in the dataset metadata record, e.g. the dataset title should match exactly, the same Creators should be listed, etc. The readme file should be saved with the name README_[Creator surname]_[Publication year]. The file name should not exceed 32 characters. Examples: README_Smith_2025.txt; README_Jones-etal_2025.txt. Text within square brackets is instructional and should be deleted from the final version of the readme.] 1. ABOUT THE DATASET -------------------- Title: Running economy benefits of shoes incorporating advanced footwear technology decrease with increasing incline. University of Leeds.

The data are gross metabolic rate (rate of oxygen consumption) in two running shoe conditions - Nike ZoomX Vaporfly Next% shoe (VF) and Nike ZoomX Streakfly shoe (SF). The running economy benefit of VF relative to SF decreased with increasing incline. Cite as: Askew, G.N., Hill, S., Payne, M., Stewart, T., Charles, D. and Brown, A.P.

PROJECT AND FUNDING INFORMATION ---------------------------------- This dataset was not created in the course of a funded project. 4. CONTENTS ----------- File listing Askew et al data.xlsx Data are gross mass-specific metabolic rate for 12 participants wearing one of two models of shoe at four different gradients. Date are mass for two models of shoe of six different UK sizes. VF - Nike ZoomX Vaporfly Next% shoe SF - Nike ZoomX Streakfly shoe 5. METHODS ---------- Gross metabolic rate was determined using a portable gas analysis system. Steady-state rate of oxygen consumption was determined from the plateau in the rate of oxygen consumption, having established that the respiratory exchange ratio did not exceed 1.
