Abstract
Purpose
The torque–duration relationship in muscle group exercise is characterized by two parameters, the critical torque (CT) and the W prime (Wʹ), which define the limit of tolerance. These parameters have significant utility in assessing health and disease. However, there is a lack of information regarding the optimization of CT and/or Wʹ gains through manipulation of resistance training (RT) variables, especially in older adults. Therefore, this study aimed to investigate the impact of different intensities of RT, specifically higher intensity RT (HIRT) versus lower intensity RT (LIRT), on CT and Wʹ in postmenopausal women.
Methods
The study spanned 12 weeks of RT. Postmenopausal women were randomized into three groups: control group (CG, n = 14), LIRT (loads necessary to perform 27–31 repetitions, n = 17), and HIRT (loads necessary to perform 8–12 repetitions, n = 14).
Results
Compared to the CG group, the LIRT group exhibited a significant increase in CT (15%, P < 0.05), while the HIRT group showed a significant increase in Wʹ (36%, P < 0.05).
Conclusions
Different intensities of RT result in distinct adaptations of torque–duration relationship parameters (Wʹ and CT) in postmenopausal women.
