Summary
Physical inactivity is rising among Indians, leading to early noncommunicable disorders. This study establishes normative values for the incremental shuttle walk test (ISWT) in healthy Indian adults, crucial for early exercise capacity assessment.
Area of Science:
- Exercise Physiology
- Public Health
Background:
- Physical inactivity is a growing concern in India, contributing to premature noncommunicable diseases.
- Accurate assessment of exercise capacity is vital for early detection and management.
Purpose of the Study:
- To determine normative values for the incremental shuttle walk test (ISWT) in a healthy Indian adult population.
- To provide a reliable reference for evaluating exercise capacity in Indians.
Main Methods:
- Recruited 862 healthy Indian adults aged 17-75 years.
- Categorized participants into three age groups: young, middle, and old adulthood.
- Administered the incremental shuttle walk test (ISWT) following a standardized protocol.
Main Results:
- Established average incremental shuttle walk distances for males and females across different age groups.
- Identified age and gender as significant predictors of incremental shuttle walk distance (ISWD).
- Developed predictive equations for ISWD based on age and gender.
Conclusions:
- Generated reference values for the ISWT specific to the Indian population.
- Confirmed that age and gender influence physiological responses to the ISWT.
- The developed predictive equations account for 68% of the variance in ISWD, aiding clinical evaluation.
