Abstract: The aims of this study were (i)
to check whether monitoring of both the rhythm of execution
and the perceived effort is a valid tool for reproducing the same
intensity of effort in different sets of the same aquatic resistance
exercise (ARE) and (ii) to assess whether this method allows
the ARE to be put at the same intensity level as its equivalent
carried out on dry land. Four healthy trained young men
performed horizontal shoulder abduction and adduction
(HSAb/Ad) movements in water and on dry land. Muscle
activation was recorded using surface electromyography of 1
stabilizer and several agonist muscles. Before the final tests, the
ARE movement cadence was established individually following
a rhythmic digitalized sequence of beats to define the alternate
HSAb/Ad movements. This cadence allowed the subject to
perform 15 repetitions at a perceived exertion of 9–10 using
Hydro-Tone Bells. After that, each subject performed 2
nonconsecutive ARE sets. The dry land exercises (1 set of
HSAb and 1 set of HSAd) were performed using a dual
adjustable pulley cable motion machine, with the previous
selection of weights that allowed the same movement cadence
to be maintained and the completion of the same repetitions in
each of the sets as with the ARE. The average normalized data
were compared for the exercises in order to determine possible
differences in muscle activity. The results show the validity of
this method for reproducing the intensity of effort in different
sets of the same ARE, but is not valid for matching the same
intensity level as kinematically similar land-based exercises.
