Abstract: The aim of this study was to determine the importance
of muscular strength and power on a muscular endurance
performance test. Fourteen firefighter recruits performed a progressive
resistance test (PRT) followed by a specific maximum
repetition test (MRT40) on the bench press exercise with
measurements of power, strength, and muscular endurance.
Comparisons were then made to examine relationships
between the 3 muscular fitness variables. The results, expressed
in absolute form and related to body weight, indicate
that the performance in the MRT40 is significantly related (p <=
0.05) to body weight (r = 0.78), 1 repetition maximum (1RM)
(r = 0.83), maximal power (Pmax) during the PRT (r = 0.71),
Pmax produced with 40 kg in the PRT (r = 0.64), and the
average power and force applied during all repetitions in the
MRT40 (r = 0.78 and r = 20.64, respectively). The load that
expressed the maximal average power during the PRT was
47.6 +- 9.0% of the 1RM and did not show any significant
relationship with 1RM nor performance in MRT40. It was
concluded that performance in this specific upper body
endurance test depends on several variables, among which
maximum strength, body weight, and maximum absolute power
are the most important. As the ability to repeatedly apply
submaximal force is a requirement of firefighters, and other
occupations/sports, the current research suggests that the
initial goal of a training program to enhance muscular endurance
should be to increase maximum strength to a point that
the specific load being lifted during repeated actions is less
than 40% of the individuals’ 1RM. Subsequent training should
then focus on maintaining maximal strength levels and improving
local muscular endurance in the specific task.
