Influence of Eccentric, Concentric, and Dynamic Weight Training Actions on the Responses of Pleasure and Displeasure in Older Women

The aim of this study was to assess the influence of eccentric, concentric, and dynamic weight training actions on pleasure and displeasure responses in older women during and after the exercise session. Fourteen elderly women (age 68.5 ± 4.6 years) participated in the study. All the subjects completed five exercise sessions: (a) familiarization, (b) determination of 1 RM (Repetition Maximum), and (c) three sessions of weight training: one session with eccentric actions, one with concentric actions, and one with dynamic actions (concentric and eccentric). The subjects performed five exercises per session: chess press, leg extension, lat pulldown, leg curl, and lateral shoulder raise. The responses of pleasure and displeasure were measured after each series of exercise and 30 min after the exercises session, along with the subjective perception of the session. The statistical analysis used was analysis of variance for repeated measures. No significant differences were found between the responses of pleasure and displeasure obtained during and after the session (session method). Concentric sessions showed differences compared with dynamic and eccentric sessions. The responses of pleasure and displeasure can be measured by the session method in older women during exercise sessions involving concentric, eccentric, and dynamic actions. The practical application of this method may assist health professionals in monitoring training sessions with weights.
