The Effect Of Preparatory Arousal On Hand Grip Strength And 50 Metre Freestyle Swim Performance., Lewan Parker, Rebecca M. Sealey, Anne Swinbourne

International Journal of Exercise Science: Conference Proceedings

Preparatory arousal is a strategy in which an individual purposefully engages in an activity to get themselves emotionally “pumped up” or “charged up” to increase the body’s level of arousal [1]. Preparatory arousal is a common mental preparation strategy used among competitive athletes [2]. It is suggested that preparatory arousal can increase performance of simple tasks requiring maximal strength and muscular endurance and power [3]. However, the majority of preparatory arousal research has only examined non sport specific skills and thus the findings may not be transferable to actual sports that require more complex and dynamic movement patterns. With the …

The Relationship Between Stride Rates, Lengths And Body Size And Their Affect On Elite Triathletes’ Running Performance During Competition, Grant J. Landers, Brian A. Blanksby, Timothy R. Ackland

International Journal of Exercise Science

Previous research has suggested that a degree of predictability exists in the relationship between self-selected running stride rates (SR) and stride lengths (SL) with measures of body size such as mass, height and limb lengths. Significant correlations have also been revealed between these body size measures and performance and between SL and performance. However, there is also evidence to suggest that triathlon performance may be related to maintaining a longer SL during the final run. Hence, the aim of this investigation was to examine whether there was any relationship between SR and SL, with body masses and heights of senior …

Presence Of Observers Increases One Repetition Maximum In College-Age Males And Females, Steven C. Baker, Alan P. Jung, John K. Petrella

International Journal of Exercise Science

Purpose: To determine if the presence of observers affects muscular strength performance in college-age males and females. Methods: Twenty-five women and 24 men participated in the study. Two counter-balanced trials were performed in which participants completed 1-RM tests in bench press and leg press. During one trial, two members of the opposite gender observed the 1-RM tests. During the other trial there were no observers, other than the tester. Results: 1-RM for females increased 3.4±0.8 lbs on bench press (p<.001) and increased 9.2±3.8 lbs on leg press (p=.025) when observers were present. 1-RM for males increased 4.2±1.1 lbs on bench press (p=.001) and increased 18.8±5.2 lbs on leg press (p=.002) with observers present. There was no difference in the percent increase in 1-RM between males and females for either leg press (p=.71) or bench press (p=.08). Conclusion: College-age males and females lifted more weight during a 1-RM test when observers were present.
