“…Adaptation to perform these tasks can be accomplished in a variety of ways that may decrease the importance of a single measure like grip strength. Performance may depend on greater complexity as suggested by Yan and Downing (2001). Alternately, the validity of the measure and a test's sensitivity and specificity should be considered.…”

“…Richards also confirmed that men were stronger than women and right hands were stronger than left as expected (Mathiowetz et al, 1985). Interestingly; however, a recent study on four different pinches in younger and older persons (lateral, chuck, 4-finger, and 5-finger) suggested that aging may not be related to force output (Yan & Downing, 2001). Grip span and style in performance may contribute in a more complex manner than a strength measure alone.…”

Objective. The progress of adults after total hip replacement (THR) was measured baseline to discharge using the Functional Independence Measure (FIM). Measures of effectiveness and efficiency were investigated. Additionally, although grip strength is frequently evaluated, its relationship to impact on functional gains after THR is unknown and was explored in this study. Method. A retrospective chart review was conducted on 41 patients' progress in acute rehabilitation following THR. Baseline and discharge FIM subscales of self-care, mobility, and locomotion were compared using paired t-tests with post hoc correction for type I error. Effectiveness and efficiency indicators on FIM subscale improvement were calculated. Grip strength was compared to expected values by age and gender using one-sample t-tests. Then, grip strength and FIM subscale scores were correlated using Pearson correlation. Results. FIM subscale scores each improved 2.1 points on average. Statistically significant improvement was made in 10 subscales of self-care, mobility, and locomotion. Grip strength was significantly less than expected norms in six of 14 subgroups after surgery; four of eight were female subgroups. There were no significant correlations between grip strength and any FIM subscale. Conclusion. Improvement in functional performance, as measured by FIM, was made on all FIM subscales. Grip strength after THR was moderately decreased from the norm. Results suggest that loss of grip strength alone may not adversely affect functional performance.

“…The examinees were not allowed to move from the initial position during the test trial, nor could they lean the hand or the device against the thigh or another part of the body. The power grip, in which all the fingers are flexed around the device, was chosen as it could produce a higher level of force than the other grips (the precision grip, the manipulative grip, or various tool and pinch grips) [32].…”

Aim. The research aimed to highlight the importance of morphological parameters and handgrip muscle force contractility in the selection of fifteen-year-old water polo players of various performance levels. Materials and Methods. The present research was conducted with a sample of 103 examinees, 37 out of whom belonged to the control group (CG), 33 were U15 water polo national league players (WNL), and 33 were water polo players from Serbian U15 national team (WNT). Besides the basic morphological parameters, the contractile properties of the left and right handgrip muscle force (HG_L and HG_R) were measured exploring two separate dimensions of contractility: maximal muscle force-F max , and maximal explosive force-RFD max. Results. The research results showed the existence of a general statistically significant difference between the three groups of participants, both in morphological space (Wilks' Lambda Value: 0.333, F relation: 11.61, p = 0.000) and in muscle force and explosivity (Wilks' Lambda Value: 0.590, F relation: 3.31, p = 0.000). In addition, the results indicated that the WNT players had higher values of F max and RFD max than the CG participants (32.8% for F max _HG_R and 63.7% for RFD max _HG_R) and the WNL players (28.8% for F max _HG_L and 43.0% for RFD max _HG_R). This suggests that the higher values of handgrip maximal explosive force and maximal muscle force may be attributed to adaptive training effects on their upper extremities. Conclusion. The results of the present study suggest that the contractile characteristics of the handgrip muscle force (F max and RFD max) as well as morphological parameters (body height and body mass) are significant in the selection of U15 water polo players.

“…Previous investigations in adult (power) grip strength have examined: age group (Frederiksen 2006, Rantanen 1998 and gender (Nicolay 2005); elbow position (Mathiowetz); wrist position (O'Driscoll 1992); gloves (Sudhakar); and hand shape (Clerke 2005) The interaction between aging and grip span on force generation capability has been investigated while performing chuck and lateral pinch grips (Yan, 2001). The senior group generated similar (and in a few cases higher) peak grip strength compared to the younger.…”

Grip Span and Aging: Does the Grip Strength-Span Relationship Change with Age?

Grip strength has been well studied in conjunction with product and individual characteristics including age. Design characteristics for products targeted to older adults frequently include larger or chunkier handles or grips. To understand motivation for these design choices, this investigation assessed grip strength at 5 grip spans of 31 participants in two age groups. The downward shift in the grip strength/span curve can be attributed to the decrease in strength with age associated with loss of type II muscle fibers in all muscles (which was more pronounced for male participants). However, there was no shift in the grip strength/span curve peak to a wider grip. Thus the affinity for chunkier handles (increased volume, contact surface area, and grip span) and grip designs for older adults is not motivated by a shift in peak grip strength over the tested grip span.
