Oxygen threshold (OT) is a key index that can reflect the ability to resist offensive skill performance in elite badminton players during the special preparation phase, which can be estimated when utf8_output = 'false ‘separated methods: A total of 20 professional elite male badminton players at the national level were recruited as research subjects. A total of twenty male elite players of the Iraqi badminton national team were included in this study. Oxygen threshold, total energy expenditure was monitored with wearable metabolic tracking devices and measured the clone endurance entraining specifically in sport literary offense skill performance. Scores correlated significantly with the O2 threshold and offensive skill endurance (r =. 71, p <. 01), and between total energy expenditure and endurance performance (r=0. 50, p <0.05). The resilience of the physiological system to high strain has been associated with higher levels of sustained offensive skill performance during periods of heightened training stress.
