Resistance training at different intensities promotes different adaptations on the parameters of torque–duration relationship in postmenopausal women

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...

Description
Summary: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
