Impact of isometric handgrip exercise on mental exhaustion and focus during logic tasks

INTERVENTION: Intervention1: Handgrip Exercise with Therapy Ball: Participant will perform intermittent Isometric Handgrip Exercise (IHE) using a therapy ball on left hand. Protocol of IHE consist of 18‐seconds squeeze followed by 30‐seconds rest until the completion of logical reasoning problem solving task. Logical reasoning task will be given on a printed paper and participant will do the task using right hand simultaneously with the IHE using left hand. Control Intervention1: Non Exercise healthy subject as comparator or control.: Control group participant will hold the therapy ball on left hand but without any squeeze exercise, while solving the logical reasoning questionnaire with the right hand. CONDITION: PRIMARY OUTCOME: 1. Cognitive Assessment Score ; 2. Fatigue severity Score ; Timepoint: 1. Baseline ; 2. Just after intervention ; SECONDARY OUTCOME: Logical Reasoning Questionnaire ScoreTimepoint: Post‐intervention on the same day INCLUSION CRITERIA: Clinically healthy right‐handed 1st and 2nd year MBBS students willing to participate and give consent.
