Relationship Between Psychological Factors and Acute Strength Task Performance
Title
Relationship Between Psychological Factors and Acute Strength Task Performance.
Creator
Haischer, Michael H., Zourdos, Michael C., Florida Atlantic University, College of Education, Department of Exercise Science and Health Promotion
Abstract/Description
The purpose of this research was to investigate if various psychological wellbeing assessments can predict maximal strength performance and self-scored rating of perceived exertion (RPE) in the back squat. Fifty-eight resistance-trained males and females were recruited, and reported to the laboratory on one day. Subjects completed eight different scales and questionnaires before completing one-repetition maximum (1RM) testing of the squat, followed by two single-repetition sets at 30%, 40%,...

Fifty-eight resistance-trained males and females were recruited, and reported to the laboratory on one day. Subjects completed eight different scales and questionnaires before completing one-repetition maximum (1RM) testing of the squat, followed by two single-repetition sets at 30%, 40%, 50%, 60%, 70%, 80%, and 90% of 1RM, and a set to volitional fatigue at 70% of 1RM. Cognitive anxiety and hypersomnia were found to be positive and negative predictors (p<0.05), respectively, of 1RM performance. Further, self-confidence, grit, and perceived recovery status were significant negative predictors of RPE (p<0.05). Finally, PRS was discovered to be a positive predictor of subject-reported 1RM self-efficacy (b=0.39, t=3.14, p<0.01, R2=0.15).

Abstract/Description
The primary purpose of this study was to investigate the effect of acute high-intensity interval exercise (HIIE) vs. continuous moderate-intensity exercise (CME) on serum CTRP9 and brachial FMD responses in obese and normal-weight subjects. Sixteen participants (9 obese and 7 normal-weight) completed HIIE and CME in a randomized fashion. Our results showed a significant time effect for CTRP9 immediately following acute HIIE and CME in both groups. Furthermore, both significant treatment by...
Show moreThe primary purpose of this study was to investigate the effect of acute high-intensity interval exercise (HIIE) vs. continuous moderate-intensity exercise (CME) on serum CTRP9 and brachial FMD responses in obese and normal-weight subjects. Sixteen participants (9 obese and 7 normal-weight) completed HIIE and CME in a randomized fashion. Our results showed a significant time effect for CTRP9 immediately following acute HIIE and CME in both groups. Furthermore, both significant treatment by time and group by time interactions for FMD were observed following both exercise protocols, with greater CME-induced FMD response in obese subjects than normal-weight subjects. Additionally, a positive correlation in percent change (baseline to peak) between CTRP9 and FMD was observed following acute CME. These findings support acute CME for improvement of endothelial function in obesity. Furthermore, the novel results from this study provide a foundation for additional examination of the mechanisms of exercise-mediated CTRP9 on endothelial function.
