Highlights

  • After detraining functional and concurrent training, maintain functional fitness.

  • Even after 28 months of detraining active older women maintained your fitness level.

  • Concurrent training seems more effective in maintaining lower-body adaptations.

  • The inactivity reduces functional fitness drastically in sedentary older women.

  • Physical training produces a reserve of functional fitness for detraining periods.

Abstract

Purpose

To assess the impacts of 28 months of detraining imposed by the COVID-19 pandemic on the functional fitness of older women practicing functional or concurrent training.

Material and Methods

A clinical trial was conducted with 16 weeks of intervention and 28 months of detraining imposed by the COVID-19 pandemic. Ninety-five participants were allocated to functional training (FT - 32), concurrent training (CT - 31), or the control group (CG - 32). All the dependent variables were measured pre-training, post-training, and after the detraining period. The functional fitness was assessed by the put on and take off a t-shirt (PTS - upper limbs), timed up and go (TUG - dynamic balance), five times sit-to-stand (FTSST - lower-limb muscle power), gallon-jug shelf-transfer (GJST - global function), and 10 m walk (W10 m - walking ability) tests.

Results

Sixty-three women remained after the detraining period, twenty-four in the FT (66.0 ± 3.8 years), twenty in the CT (65.0 ± 4.3 years), and nineteen in the CG (69.6 ± 5.9 years). Comparing the detraining vs. the pre-intervention, the FT and CT showed a smaller reduction than CG for the PTS (βFT = -2.296; βCT = -1.914), timed up and go (βFT = -0.705; βCT = -0.600), five times sit-to-stand (βFT = -1.970; βCT = -2.970), gallon-jug shelf-transfer (βFT = -1.512; βCT = -1.003), without differences in the 10 m walk. Also, the concurrent training showed a smaller reduction than the functional training in the FTSST (β = 1.000).

Conclusion

Even after a long detraining period imposed by the COVID-19 pandemic, FT and CT practices were effective strategies for maintaining the functional fitness of older women.
