The effect of MF induced by exposure time to social media smartphone apps on inhibitory control, heart rate variability (HRV), and high-intensity physical effort following a resistance exercise session might indicate whether strength and conditioning professionals should suggest avoiding smartphone usage before a resistance exercise session.
The objective of this study was to analyze the effect of mental fatigue on inhibitory control, HRV, and countermovement jump (CMJ) in trained adults after resistance exercise.
A total of 16 trained males (21.4 ± 3.3 years) volunteered in this study. The participants performed resistance exercises with and without mental fatigue. The Stroop Task, countermovement jump, and heart rate variability were evaluated before and after the resistance exercise. The participants used smartphones in the mental fatigue condition, whereas the participants watched TV in the control condition.
No condition × time interaction was found for the Stroop accuracy ( = 0.87), CMJ ( = 0.68), SDNN ( = 0.15), or pNN50 ( = 0.15) in the heart rate variability. An interaction was found for Stroop response time ( = 0.01) with a higher response time for the mental fatigue condition ( = 0.01).
Mental fatigue impaired the inhibitory control performance after a resistance exercise session in trained adults.
社交媒体智能手机应用程序暴露时间引起的心理疲劳对抑制控制、心率变异性（HRV）和抗阻运动后的高强度体力活动的影响，可能表明力量和体能专业人员是否应该建议在抗阻运动前避免使用智能手机。
本研究旨在分析心理疲劳对经过训练的成年人在抗阻运动后的抑制控制、HRV 和反向跳（CMJ）的影响。
共有 16 名经过训练的男性（21.4±3.3 岁）自愿参加了这项研究。参与者在有和没有心理疲劳的情况下进行抗阻运动。在抗阻运动前后评估了斯特鲁普任务、反向跳和心率变异性。参与者在心理疲劳状态下使用智能手机，而在控制状态下观看电视。
在心率变异性方面，斯特鲁普准确性（ = 0.87）、CMJ（ = 0.68）、SDNN（ = 0.15）或 pNN50（ = 0.15）没有出现条件 × 时间的交互作用。对于斯特鲁普反应时间（ = 0.01）出现了交互作用，心理疲劳状态的反应时间更高（ = 0.01）。
心理疲劳会损害经过训练的成年人在抗阻运动后的抑制控制表现。
