Interventions

  • Mild-intensity physical fatigue — OTHER
    Participants will undergo mild-intensity physical fatigue through a structured treadmill training protocol. The training will be conducted within a target heart rate range of 50-60% of their maximum heart rate (HRmax), ensuring controlled and consistent exercise intensity. This approach aims to induce mild physiological stress while maintaining safety and feasibility for all participants.
  • Moderate-intensity physical fatigue — OTHER
    Participants will undergo Moderate-intensity physical fatigue through a structured treadmill training protocol. The training will be conducted within a target heart rate range of 60-70% of their maximum heart rate (HRmax), ensuring controlled and consistent exercise intensity. This approach aims to induce mild physiological stress while maintaining safety and feasibility for all participants.
  • High-intensity physical fatigue — OTHER
    Participants will undergo High-intensity physical fatigue through a structured treadmill training protocol. The training will be conducted within a target heart rate range of 70-80% of their maximum heart rate (HRmax), ensuring controlled and consistent exercise intensity. This approach aims to induce sufficient physiological stress while maintaining safety and feasibility for all participants.

Study Details

This study aims to determine how different levels of physical fatigue influence cognitive load and performance during dual-task activities. 1. To assess the changes in cognitive task performance under varying levels of physical fatigue. 2. There is an association between cognitive loading and physical fatigue.

Arms

  • Experimental: Group 1
    Participants with a target Heart rate range of 50-60% of their maximum heart rate. All members of Group 1 who meet the eligibility criteria will perform a cognitive task before undergoing mild-intensity physical fatigue induced by treadmill training. After that participants will complete the cognitive task again. To eliminate bias, three different levels of physical exertion will be randomly assigned.
  • Experimental: Group 2
    Participants with a target Heart rate range of 60-70% of their maximum heart rate. All members of group 2 who meet the eligibility criteria will perform a cognitive task before undergoing moderate-intensity physical fatigue induced by treadmill training. After that participants will complete the cognitive task again. To eliminate bias, three different levels of physical exertion will be randomly assigned.
  • Experimental: Group 3
    Participants with a target Heart rate range of 70-80% of their maximum heart rate. All members of group 3 who meet the eligibility criteria will perform a cognitive task before undergoing high-intensity physical fatigue induced by treadmill training. After that participants will complete the cognitive task again. To eliminate bias, three different levels of physical exertion will be randomly assigned.
