Brief summary: 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.

Detailed description: Working efficiency in our daily routine is hindered by constant change, urgency, and the demands of sustained efforts, all of which contribute to health and safety problems, and are extremely imprudent of human resources in the workplace, due to which individuals would raise anxiety, causing more attention required for task completion and thereby increasing cognitive load. Cognitive loading refers to the mental effort needed to process information and perform tasks. Physical performance is not only related to physical factors, psychological factors also have the potential to determine physical performance. Mental workload is defined as the difference between the cognitive demand of a particular task and the operator's attention resources. When cognitive demands exceed available resources, mental fatigue can occur, often reflected in decreased motor function and impaired physical performance. Fatigue is recognized as a dimensional phenomenon encompassing cognitive and motor fatigue. It is debatable whether cognitive fatigue is a spontaneous phenomenon or provoked by exertion or whether cognitive fatigue is provoked by cognitive effort or also through physical exercise. Physical fatigue develops more quickly when the brain has to devote resources to highly cognitive tasks. Influence of cognitive load on the dynamics of neurophysiological adjustments during exercise which causes fatigue explained by the interaction of various psychological and neurophysiological factors including higher perceived exertion, greater perturbations of autonomic nervous system activity, and cerebral impairments leading to earlier onset of central fatigue. The brain is like other biological tissue tired out when overused. Since the impact of physical exercise on cognitive functioning is dependent on the characteristics of the physical exercise load. Previous research has demonstrated a small-to-medium negative effect of cognitive exertion on subsequent physical performance. Our study aims to explore the interplay between varying levels of physical fatigue and cognitive performance. Specifically, we will examine how different intensities of physical load affect mental load and associated physiological functions. By investigating these relationships, we seek to provide insights into optimizing performance in dual-task environments, ultimately contributing to better health and efficiency in the workplace.
