Commentary

Grip strength (HS) is considered to be a risk factor for all-cause mortality and cardiovascular disease, but the influencing factors and mechanisms contributing to this correlation are unknown.

This study examined factors associated with HS and investigated the mechanisms underlying its predictive risk value.

It was a prospective cross-sectional study and 145 participants were recruited between December 2019 and November 2020.

HS was measured using a hydraulic hand dynamometer and adjusted for body mass index (HS BMI) and body surface area (HS BSA)). and body composition was assessed by bioimpedance spectroscopy.

Physical fitness was measured using a cardiopulmonary exercise testing system.

Univariate multiple linear regression analysis and receiver operating characteristic curves (ROCs) were performed to assess the association between various participant characteristics and HS.

The results showed that there was a positive correlation between HS

BMI / HS BSA and VO 2MAX, VE , max, load max, and MET max (for both sexes).

Percentages of lean tissue, protein, total water, and inorganic salts correlated positively, and adiposity correlated negatively with HS.

Multiple regressions showed that VO and 2 max were independently associated with HS, and BS, independently associated with HS BMI in women.

Based on these analyses, HS adjusted for BMI and BSA may serve as an indicator of physical health, and HS BSA may moderately reflect the cardiorespiratory fitness level of healthy young adults, especially males.
