Effects Of Different Antagonist Protocols On Repetition Performance And Muscle Activation, Andrade Paz, Jeffrey Willardson, Roberto Simao, Humberto Miranda

Jeffrey Willardson

Objective: To investigate the acute effects of different antagonist manipulation protocols on maximal repetition performance and muscle activation during seated row (SR) exercise. Methods: Fifteen men (22.4 ± 1.1 years old, height 175 cm ± 5.5, weight 76.6 kg ± 7, and 12.3 ± 2.1 of body fat percentage) with previous resistance training experience (3.5 ± 1.2 years) performed four experimental protocols: (TP) one set to repetition failure of SR exercise; (AS) Antagonist static stretching for the pectoralis major (PM) followed by one set of SR; (PNFA) Proprioceptive neuromuscular facilitation for PM followed by one set of the SR; (APS) …

The excess post-exercise oxygen consumption (EPOC) consists of the excess oxygen consumed above a resting state following exercise. Performance of resistance exercise can significantly disrupt the body’s homeostasis, with the EPOC being dependent on the specific combination of prescriptive variables. Presently, the effects of different repetition velocities on VO2 and caloric expenditure during and following resistance exercise bouts have not been completely elucidated. Objective: To examine the effect of different repetition velocities on EPOC and total energetic expenditure during and following resistance exercise bouts. Methods: Twenty women (34.6 ± 5.5 years; 159 ± 4.1 cm; 55.1 ± 3.4 kg; 24±2.5 …

Examining The Direction Of Imagery And Self-Talk On Dart-Throwing Performance And Self Efficacy, Jennifer Cumming, Sanna M. Nordin, Robin Horton, Scott Reynolds

The study investigated the impact of varying combinations of facilitative and debilitative imagery and self-talk (ST) on self-effi cacy and performance of a dart-throwing task. Participants (N = 95) were allocated to 1 of 5 groups: (a) facilitative imagery/facilitative ST, (b) facilitative imagery/debilitative ST, (c) debilitative imagery/facilitative ST, (d) debilitative imagery/debilitative ST, or (e) control. Mixed-design ANOVAs revealed that performance, but not self-effi - cacy, changed over time as a function of the assigned experimental condition. Participants in the debilitative imagery/debilitative ST condition worsened their performance, and participants in the facilitative imagery/facilitative ST condition achieved better scores. These fi ndings …
