Resumo
The deadlift is a fundamental exercise
used in the development of whole body strength and
a common element in resistance training programs for all levels.
However, many practitioners report the fatigue of forearm
muscles and possibly a lack of grip strength as obstacles to
exercise performance, which may lead to the use of ergogenic
aids, such as lifting straps. The objective of this study was to
evaluate kinematic variables during the execution of multiple sets
of deadlift with (WS) and without (NS) lifting straps. Eleven
subjects (25 6 3.3 years) with an average of 4 6 2.6 years of
resistance training experience were enrolled in the study. After
the 1 repetition maximum (1RM) test WS and NS, subjects
performed separate trials of 3 sets to failure at 90% of 1RM in
a counterbalanced fashion. With straps resulted in lower speed
(0 to 225%) (23 to 210%) and greater force (20–28%) and
duration (concentric phase: 0–13%) when compared with NS.
Therefore, it is concluded that the use of straps directly influences
exercise performance that requires manual grip strength,
increasing the amount of work performed by the target muscles.
