Participants enrolled in this group will be performing dominant leg isometric knee extension. The knee will be 35° flexed from a fully extended position when performing isometric knee extension using a hand-held dynamometer retrained by a belt. The intervention duration will be 8 weeks. A single session will consist of performing 4 sets of 30% MVC (calculated using a dynamometer) of unilateral knee extension isometrics with a maximum 2 minutes contraction time/ hold time followed by a rest/ recovery period of 1 minute during each set.

Free and delayed recall are measures of episodic memory. A 15-item word list of highly frequent words will be used. At the outset, a "ready" cue will appear in the centre of the computer screen. On the computer screen, each word will be displayed individually for 3 seconds. After the 15th word, the participant will be given a 60-second to write down the words in any order. The Delayed Recall test will be used to evaluate long-term memory about 12 minutes later. During the delayed memory task, participants will be allowed 60 to recall as many words from the list shown before.

Go/ No Go task or stop signal task is a measure of executive functioning. This tool tests participant's ability to not respond thus measuring response inhibition and impulsivity. The participant is required to respond within 2 seconds when the screen says 'Go' and should resist responding when 'No' appears.

The Stroop colour-word test is considered one of the gold standards of attentional measures and is one of the most widely used instruments in clinical and experimental neuropsychological settings. In the Stroop-A test, the reader must note the colour rather than the word as soon as the word is highlighted. In the Stroop-B, the evaluator points to the columns of coloured words, and the subject reads what is written. To draw results Stroop effect is calculated by subtracting the reaction time of compatible trials from incompatible trials.

The trail-making test is a cognitive tool used for the assessment of processing speed, attention, and cognitive flexibility. The test requires the person to draw lines in ascending order from 1-25 in the case of trail-making A. Trail-making A and B have numbers, as well as letters, joined in an alternating sequence. The total score is calculated by subtracting the time taken for part A from the time taken to attempt part B in seconds. If the person cannot complete the test in 5 minutes the test is discontinued.

The Borg Category-Ratio scale, also known as the Borg CR-10 scale, is a self-report tool for gauging perceived effort intensity. It is similar to the Borg Rating of Perceived Exertion Scale, but ratings are from 0 to 10. This general intensity scale has category-ratio qualities that are more suited to the subjective feelings of effort, including pain, discomfort, and localized tiredness. Participants will be cued to give their ratings using the standardized questions: "How hard do you feel your hand /leg muscles are working?" and will be scored against a rating of 0 to 10.
