Abstract
Background:
Handgrip strength is a quick and reliable indicator of general muscle strength and functional capacity. Its relationship with muscle endurance, as assessed by Mosso’s Ergograph, has not been widely explored in young adults.

Aim:
This study aimed to compare handgrip strength and muscle endurance in physically active and inactive young adult females and analyze the correlation between grip strength and endurance parameters.

Methods:
Thirty female participants aged 22–26 years were categorized as physically active or inactive using the IPAQ (Table 1). The handgrip strength was measured using a standard dynamometer. Muscle endurance was assessed using Mosso’s Ergograph by recording work done (kg·m), time to fatigue, and the total number of contractions. Independent sample t-tests were used to compare the groups. Pearson’s correlation analysis was used to examine the association between handgrip strength and endurance measures.

Results:
The physically active group demonstrated significantly higher mean handgrip strength (Active vs. Inactive, p = 0.0048) and greater work done (kg·m) (Active vs Inactive, p = 0.0304). There was a moderate positive correlation between grip strength and work done (kg·m) (r = 0.57, p = 0.012) and between grip strength and the number of contractions (r = 0.55, p = 0.014).

Conclusion:
Handgrip strength shows a moderate positive correlation with muscle endurance as measured by Mosso’s Ergograph. This supports the use of handgrip dynamometry as a simple, indirect proxy for assessing general muscle endurance, with implications for musculoskeletal health, physiology education , rehabilitation protocols, and fatigue-related research.
