TEIXEIRA, Marcela Donatelli Meibach et al. Grip and pinch strength in Brazilian Air Force cadet pilots: a comparative study between men and women. Fisioter. Pesqui. [online]. 2009, vol.16, n.2, pp. 143-147. ISSN 1809-2950. http://dx.doi.org/10.1590/S1809-29502009000200009.
The aim of this study was to quantify the hand muscle strength during grip and pinch movements, and to compare results between men and women. Thirty-one cadet pilots (17 men and 14 women) from the Brazilian Air Force Academy were assessed by means of Jamar dynamometer (grip) and Preston Pinch Gauge (pinch). Female cadets mean grip was 31.4 kgf at dominant hand and 29.3 kgf at non-dominant hand; in male subjects, corresponding values were 43.6 kgf and 41.2 kgf. Mean female lateral pinch at the dominant hand was 7.4 kgf and men's, 10.2 kgf (p<0.01); tripod pinch values were 7.2 kgf at dominant side and 7.1 kgf at non-dominant for women, and 9.8 kgf and 9.50 kgf for men, respectively (p<0.01); women pinch values were 4.9 kgf and 4.6 at dominant and non-dominant hands, and men's, 6.5 kgf and 5.7 kgf respectively (p<0.01). Grip, pinch, lateral pinch, and tripod pinch were all significantly higher (p<0.01) in men than in women. Both sexes showed higher strength at the dominant side, except of the tripod pinch. When compared to the population in general, there are little differences among cadets, both as to sex and dominance. These findings may be of relevance both for pilots performance and physical therapy assessment.
