Self-selected intensity, ratings of perceived exertion, and affective responses in sedentary male subjects during resistance training

Abstract

[Purpose] This study examined the exercise intensity and psychophysiological responses to a self-selected resistance training session in sedentary male subjects. [Subjects and Methods] Twelve sedentary male subjects (35.8 ± 5.8 years; 25.5 ± 2.6 kg·m2) underwent four sessions at 48-h intervals: familiarization; two sessions of one repetition maximum test and a resistance training session in which they were told to self-select a load to complete 3 sets of 10 repetitions of chest press, leg press, seated rows, knee extension, overhead press, biceps curl, and triceps pushdown exercises. During the latter, the percentage of one repetition maximum, affective responses (feeling scale), and rating of perceived exertion (OMNI-RES scale) were measured. [Results] The percentage of one repetition maximum for all exercises was >51% (14–31% variability), the rating of perceived exertion was 5–6 (7–11% variability), and the affective responses was 0–1 point with large variability. [Conclusion] Sedentary male subjects self-selected approximately 55% of one maximum repetition, which was above the intensity suggested to increase strength in sedentary individuals, but below the recommended intensity to improve strength in novice to intermediate exercisers. The rating of perceived exertion was indicative of moderate intensity and slightly positive affective responses.

Comparison of the acute effects of traditional versus high velocity resistance training on metabolic, cardiovascular, and psychophysiological responses in elderly hypertensive women

“… 39 Other studies observed similar affective responses to RT in elderly sedentary women, trained young women, and sedentary men. 18 , 40 , 41 The initial intensity selected to start an RT program may be very important to training adherence, especially in elderly people with hypertension.…”

“…To our knowledge, this is the first study that analyzed the acute responses of pleasure and RPE in two different methods (traditional vs. cluster-set). In addition, there are still few studies that analyzed the pleasure responses in the RT and most of them investigated the effect of the intensity of the training on this variable (Benites, Alves, Ferreira, Follador, & da Silva, 2016;Elsangedy, Krinski, da Silva Machado, Okano, & da Silva, 2016;Portugal et al, 2015). However, the configuration of different trainings, due to the manipulation of other acute training variables, besides the intensity, might modify the psychophysiological responses during the resistance training, more specifically, the rest interval.…”

Potential Utility of Self-Report Measures of Affect to Optimise Exercise Adherence in People with Type 2 Diabetes

“…injury) [70], each of which can impact exercise adherence. Such studies have typically included athletes [41,42,[70][71][72][73], otherwise healthy active or inactive adults [74][75][76][77][78][79][80] and adolescents/children [81][82][83][84], rather than focussing on clinical populations such as T2D.…”

“…Numerous studies have examined exercise participants' ability to self-regulate exercise intensity using measures of affect. When based on their affective response, both inactive and active healthy males and females, select an intensity of approximately 55% 1RM for resistance exercise and slightly above ventilatory threshold/50% VO2 max for aerobic exercise, which is equivalent to or above the suggested intensity to provide health and fitness benefits [74,76,77,80,83,91]. Allowing participants to choose the intensity at which they exercise based on their affective response results in increased perceived autonomy and control [74,92].…”

This in turn promotes adherence as indicated by a significant improvement in weekly PA levels [66,79,82], compared to heart rate-guided prescription.…”
