People in different subgroups age at different rates. Surveys containing biomarkers can be used to assess these subgroup differences. We illustrate this using hand-grip strength to produce an easily interpretable, physical-based measure that allows us to compare characteristic-based ages across educational subgroups in the United States. Hand-grip strength has been shown to be a good predictor ...

Aging is associated with sarcopenia, which is a loss of skeletal muscle mass and function. Coenzyme Q10 (CoQ10) is involved in several important functions that are related to bioenergetics and protection against oxidative damage; however, the role of CoQ10 as a determinant of muscular strength is not well documented. The aim of the present study was to evaluate the determinants of muscular stre...

Low birth weight has been associated with reduced hand grip strength, which is a marker of future physical function and disease risk. The aim of this study was to apply a twin pair approach, using both 'individual' data and 'within-pair' differences, to investigate the influence of birth weight on hand grip strength and whether this association may be mediated through fat free mass (FFM). Parti...

Purpose: The purpose of this study is to investigate the relationship between myoelectric activities of wrist flexors and extensors and hand grip strength at four different positions of shoulder and elbow joints. Subjects: Thirteen normal male university students volunteered to participate in this study. Their mean ages, weights and heights were 19.6 (± 1.06) years, 75.9 (± 7.51) Kg and 173.5 (...

BACKGROUND Poor grip strength is an indicator of frailty and a precursor to functional limitations. Although poor grip strength is more prevalent in older disabled African American women, little is known about the association between race and poverty-related disparities and grip strength in middle-aged men and women. METHODS We examined the cross-sectional relationship between race, socioecon...

PURPOSE The finger grip and the palm grip are the most common needle holder grips for hand suturing in surgery. The major advantages of the palm grip are an increased versatility and the possibility to apply controlled force. However, there is a risk for a potential loss of precision and uncontrolled movement of the needle when disengaging the ratchet mechanism of the palmed instrument. The pur...

It has been suggested that athletes with longer fingers and larger hand surfaces enjoy stronger grip power. Therefore, some researchers have examined a number of factors and anthropometric variables that explain this issue. To our knowledge, the data is scarce. Thus, the aim of this study was to investigate the effect of hand dimensions, hand shape and some anthropometric characteristics on han...
