| Descripció: | Purpose: To determine the association between handgrip muscle strength and anthropometric variables associated with muscle mass in a sample of female Mexican older adults. Methods: Volunteers were 40 healthy women (Age = 61.15 ± 6.1 yr.; Body Mass Index [BMI] = 27.9 ± 7.4 kg/m2) residing in Ensenada, Baja California, Mexico. A hand dynamometer (BioRadio, Great Lakes NeuroTechnologies, Cleveland, OH), was used to measure handgrip strength on the dominant hand. The maximal circumference of the dominant forearm was measured following the protocol by the International Society for the Advancement of Kinanthropometry. Bioelectrical impedance analysis (InBody 770; Cerritos, CA) was used to measure body composition. Appendicular skeletal muscle (ASM) relative to BMI and skeletal muscle index (SMI) relative to height (m2) were analyzed as anthropometric sarcopenic indicators. Results: The older adult’s mean handgrip strength and forearm circumference were 17.0 ± 3.3 kg and 25.5 ± 2.3 cm, respectively. The ASM relative to BMI was 0.6 ± 0.1 and the SMI relative to height was 6.7 ± 0.8. Handgrip strength was related to arm circumference (r = 0.56, p = 0.0001, 95% CI= 0.31, 0.75, R2= 0.32), and SMI relative to height (r = 0.37, p = 0.01, 95% CI= 0.08, 0.62, R2= 0.14). The ASM relative to height was unrelated to handgrip strength (r = 0.12, p = 0.45, 95% CI= -0.20, -0.42, R2= 0.01). Conclusions: Reduced handgrip strength and SMI were observed in the female participants compared to international norms. Forearm circumference and SMI relative to height might be considered appropriate assessment measures to explore sarcopenic condition in female Mexican older adults. |
