Abstract
[EN] Background: Depression is associated with a decreased cardiorespiratory fitness,
and physical activity [PA] levels, higher rates of obesity, and dysfunction in autonomic
control of heart rate [HR]. However, these parameters were mostly recorded with indirect
methods. Thus, the aim of the current study was to investigate the relationships between
depression scores and objective measures of body fatness, autonomic indices (i.e. HRV
and HRR), cardiorespiratory fitness and PA levels; and subsequently to present the best
predictive models of depression scores for this population, based on these variables.
Methods: Thirty-five non-exercising women (26–43 years; maximal oxygen
consumption [VO2max] ∼ 17.4–38.3 mL/kg/min) volunteered for participation in
this study. All participants responded to the Beck Depression Inventory [DBI] and
were evaluated for body mass index [BMI], percentage of body fat, sum of skinfolds,
and VO2max. Subsequently, over four consecutive days, an orthostatic test and
a submaximal exercise on a cycle ergometer were performed to record HRV and
HRR, respectively. In addition, incidental PA was recorded during 5 consecutive days
using accelerometers.
Results: depression scores were related to VO2max (r = −0.446, p = 0.007) and
the sum of skinfolds (r = 0.434, p = 0.009). Several stepwise multiple linear regression
models were performed and only VO2max was revealed as an independent predictor of
the Beck scores (ß = −0.446, R² = 0.199, p = 0.007).
Conclusion: The present study revealed that VO2max and the sum of skinfolds were
moderately related to depression scores, while VO2max was the only independent
predictor of depression scores in female workers.
