Title: Analysis of running technique and efficiency when using Nike Air Zoom Alphafly shoes. Objectives: The main goal is to identify possible changes in selected physiological parameters and biomechanics of running when using Nike Air Zoom Alphafly shoes compared to standard running shoes. Methods: A 3D treadmill (H/P Cosmos Gaitway II S, Germany) was used in the analysis of running biomechanics. For the analysis of physiological parameters, the Metalyzer device was used within the spiroergometric examination of the run. The Borg scale was used to analyze the subjective assessment of the load. A paired T-test of Excel software was used to process the results. Results: The results of the work partially show a change in the biomechanics of running. A statistically significant difference was recorded at all speeds (15 km/h, 18 km/h, 21 km/h) in loading rate (p15 = 0,003; p18 = 0,000; p21 = 0,001) and time to impact peak (p15 = 0,017; p18 = 0,022; p21 = 0,003). At a speed of 15 km/h, an additional difference in running cadence (p = 0,044) was noted. The results show a statistically significant change in the economics of running all measured parameters, in oxygen intake converted to kilograms of weight (p = 0,003), minute ventilation (p = 0,000), respiratory rate (p = 0,000), respiratory coefficient (p...
