Yoga is a collection of physical, mental, and spiritual exercises that have their roots in ancient India. They are meant to regulate (yoke) and rest the mind while acknowledging an objective witness awareness that is unaffected by the mind (Chitta) and everyday suffering (Dukha). Hinduism, Buddhism, and Jainism all have different schools of yoga with different practices and objectives, and both ancient and contemporary yoga is practiced all across the world. A total score obtained from a series of standardised tests or subtests created to gauge human intelligence is known as an intelligence quotient (IQ). This study was conducted to check whether the concentration exercises of yoga improve active athletes’ mental ability in terms of intelligence quotient or not. For the study, a sample of 30 collegiate athletes (aged 21.5 ± 3.5) was taken. ‘A group test of general mental ability questionnaire’ by Dr. S. Jalota was taken into account as the dependent variable. A four-week concentration training program, as a treatment, was administered to the subjects. The mental ability test was conducted before and after the completion of the program. The differences in scores were measured by paired samples t-test and the results were computed using IBM SPSS 26 software. The 0.05 level of significance was set for the study. The result showed that there was a significant improvement in the IQ of the participants after the training completion. Additional recommendations for future research were provided.
