This study investigated the effect of shoulder position on grip strength in 30 female students from Florida International University. A Jamar dynamometer was used to measure the grip strength in three testing positions (0,90 and 135 degrees of shoulder flexion with full elbow extension). The highest mean grip strength measurement was found at 135 degrees of shoulder flexion, followed by 0 degrees and then 90 degrees. An ANOVA indicated that there was a significant difference between at least two of the three positions. A Fisher's LSD post hoc test indicated that mean grip strength at 135 degrees of flexion was significantly higher than at 0 and 90 degrees of flexion.
