Background: Hand grip strength (HGS) is a predictor of upper extremity function and changes in muscle strength, physical movement and ability to undertake activities of daily living. Body mass index (BMI) is a critical indicator of physical health; however, the relationship between HGS and BMI has not yet been thoroughly examined. Objectives: The current study aims to compare HGS in low, medium, and high BMI males and females in both hands, and also investigates the correlation between HGS and anthropometric characteristics among the three BMI groups. Patients and Methods: The study included 200 participants who were divided into three groups based on their BMI (60 low, 58 medium, and 82 high). HGS was assessed using a hand-held Jamar dynamometer. BMI was assessed by an electric bodyweight height analysis machine. Data was analyzed using descriptive and inferential statistics at P < 0.05. Results: The results showed that there were significant differences in HGS (26.80 ± 5.83, 34.55 ± 7.84, and 42.30 ± 5.35 kgf; P < 0.001) among low, medium, and high BMI subjects, respectively. However, in this study ANCOVA was based on the covariance of sex; the three groups did not show major variations in RHGS and L-RHGS (P > 0.05). Weight and height strongly correlated with HGS for hands (correlation (r) ranged from 0.000-0.775). Regression analysis showed that when using sex and BMI as independent variables for predicting the dependent variable HGS, the coefficient of the determinant R 2 was 0.753 (P < 0.001). Conclusions: The current study revealed that a significant difference existed in HGS among the low, medium, and high BMI groups. A positive correlation existed between HGS and weight and height, while sex was the most significant factor affecting HGS. These findings can serve as a reference to assess HGS prediction, whereby the sex effect should be considered.

Owing to the growth of economic, people have more demand for leisure activities. How to improve customer's loyalty has become a key strategy for service management. The purpose of this study was, taking leisure resort enterprise as an example, to explore the casual relationships between service quality, brand image, customer satisfaction, and customer loyalty. A total of 300 subjects from Taiwan population were voluntarily participated in this study. The LISREL (Linear Structural Relationship) model verification results showed that the overall goodness-of-fit indices (GFI) was 0.952 and χ 2 was 128.639 (df = 95), which indicated an empirically good fit with the model. It was concluded that the service quality, brand image and customer satisfaction of leisure business have a direct relation with loyalty, and the service quality has an indirect effect on loyalty through customer satisfaction. These findings would be a reference for marketing management in the leisure enterprises.
