Abstract

The relationship between muscle strength and cognition is widely studied in older adults; however, understanding this association at younger ages may help detect markers of early cognitive changes and inform future interventions. Accordingly, we aimed to identify relationships between handgrip, whole-body, upper body, and lower body strength and cognitive functions. A total of 112 adults (aged 18-50 years) completed comprehensive measures of muscle strength, aerobic capacity, body composition, and cognitive function. Hierarchical linear regressions revealed that individuals with stronger handgrip had better mental rotation performance (standardized β = 0.39); those with greater upper body strength had superior recognition (standardized β = 0.52) and pattern separation abilities (standardized β = 0.39), but whole- and lower body strength were not associated. Results demonstrate the unique relationship between upper body strength and aspects of cognitive function, in addition to differential associations of upper body and handgrip strength with encoding, retrieval, and spatial skills. The current findings establish an association between strength and cognitive function earlier than previously thought.

期刊介绍： The Journal of Sport & Exercise Psychology (JSEP) is a peer-reviewed publication designed to stimulate and communicate research theory in all areas of sport and exercise psychology. JSEP emphasizes original research reports that advance our understanding of human behavior as it relates to sport and exercise. Comprehensive reviews employing both qualitative and quantitative methods are also encouraged, as well as brief reports of soundly designed research studies that are of special interest or importance. Areas of interest include research in social, clinical, developmental, and experimental psychology, as well as psychobiology and personality. Moreover, the terms sport and exercise may pertain to either the independent or dependent variables. Generally speaking, work on motor control processes, studies of sport as a social institution, or broader social issues are beyond the scope of JSEP. A wide variety of methods are acceptable for studying sport and exercise psychology topics.
