Background:The water activities have been indicated by health professionals increasingly with intention of enhance benefits such as weight loss, improvement of the different systems
of the body particularly muscle system, however, initial tests should be encouraged in the aquatic environment in order to detect possible force discrepancies between unilateral segments, thus
favoring the planning of individualized and specific loads, especially in situations imbalances. As such, the aim of this study was to analyze the symmetry of unilateral lower limb strength in novice
individuals in a aquarobics program.
Methods:Thirty-one individuals of mean age of 65,5 years, 8 male and 23 female, all of those individuals are beginners in a aquarobics program. For the comparison of the unilateral
symmetry we used the exercise with the burden of action for hip flexion, concomitant knee extension, with the performer to keep the ankle in plantar flexion, as recovery for a new load of action
occurred with contrary movements in the three joints. The task began with the right leg and had duration of 30 seconds in order to perform the greatest possible number of repetitions and with maximum
intensity, after 5 minutes was carried out with the left leg. To analyze the data after the confirmation of normality used the Student's test to compare segments of the group and the descriptive
analysis for exploitation of individual data.
Results:For the number of the maximum repetitions in 30 seconds for the action of hip flexion and knee extension (FQEJ) on the right and left sides of beginners individuals in water
aerobics. The absolute difference (ΔAbsol.) And the relative difference (Δ%) in the lower limbs. Resulting in FQEJ-D 21,63 (4,88), FQEJ-E 21,40 (4,71), ∆Absol -0,23 (2,13) and ∆% 0,47 (9,95). Data are
presented as mean and standard deviation. Review 02, features the absolute and relative frequency of individuals with different magnitudes at maximum repetitions in 30 seconds for hip flexion and knee
extension action (FQEJ) on the right and left sides. As the frequency percentage, 0% 7 subjects (22,58), 8 subjects 1% to 5% (25,80), 6 of 6% to 10% (19,35), 5 of 11% to 15% (16,12), 2 of 16% to 20%
(6,45) and 2 21% 25% (6,45).
Conclusions:Analysis of the data indicated no statistical difference (p = 0.27) in the comparison of the lower limbs, however, the individual observation indicated that 29% of the
sample presented discrepancy in the top sides 11% which potentially features power asymmetry between segments need a hard control strategies to quantifying unilateral and individual loads.
