Effect of strength training on the agonist-antagonist sequence to improve functional fitness in older women

Ana Paula Sena Vasconcelos, Diogo Cardozo

Resumo


Introduction: Strength training (ST) is effective to improve functional fitness (FF) in older people. However, the literature is scarce in relation to some ST methods. Objective: To verify the effect of an agonist-antagonist circuit training model (AACT) on FF in older women. Methods: Thirteen older women (68.6 ± 6.1 years, 66.4 ± kg, 1.57 ± 0.007 meters) were recruited to participate in this research. These women were submitted to the Senior Fitness Test to evaluate FF and measurements of body weight, height and calf circumference to check body composition. The training protocol was based on AACT model with exercises performed following this sequence: knee extension, knee flexion, abductor and adductor machine, bench press, rowing machine, triceps and biceps curls during eight weeks. The participants performed three sets of 8 to 10 repetitions with 30-second intervals in the circuit training model. Results: After eight weeks of AACT training, FF improved significantly (p ≤ 0.05). However, there were no differences in body composition (p ≥ 0.05). Conclusion: The training organized in an AACT model improves FF and may be used to maintain an active lifestyle and improve the quality of life in this population.

Keywords: older people, strength training, functional capacity.
