INTRODUCTION: Low neuromuscular fitness is documented in adolescents with CHD and may be associated with clinical and morphological factors, indicating the need to assess strength in this population.
OBJECTIVE: To evaluate neuromuscular fitness with a multifactorial approach and its associations with other clinical and morphological factors in adolescents with CHD.
METHODS: This is an observational, cross-sectional study with adolescents with CHD, aged between 10 and 18 years. Neuromuscular fitness was calculated by the sum of the z-scores of four strength tests. Clinical factors of CHD were assessed by medical records and questionnaire. The morphological factors assessed were waist-to-height ratio, sum of skinfolds, and upper arm muscle area. Descriptive statistics, analysis of covariance, and linear regressions were performed.
RESULTS: Sixty adolescents with CHD participated, aged 12,7 ± 2,1 years, 55% girls. Maximum isometric strength was inadequate in 33%, jump height (power) in 33%, abdominal muscle strength resistance in 78%, and upper limb muscle strength resistance in 27%. Neuromuscular fitness was inadequate in 89% (n = 53) of adolescents with CHD. In the unadjusted regression, neuromuscular fitness was associated with arm muscle area (β = 0,12; p = 0,02; R2adj = 0,08) and in the unadjusted and adjusted regression it was lower in cyanotic (vs. acyanotic) CHDs (β = -1,76; p = 0,03 R2adj = 0,24).
CONCLUSION: The findings reveal deficits in different presentations of musculoskeletal strength in a large proportion of adolescents with CHD, reinforcing the need to measure fitness from a broader perspective. Low muscle mass and the presence of cyanotic CHD may imply in reduced neuromuscular fitness in adolescents with CHD.
