Effects Of Caffeine On Repeated Upper/Lower Body Wingates And Handgrip Performance, Thomas Andre, Matt Green, Joshua Gann, Eric O'Neal, Tom Coates
Effects Of Caffeine On Repeated Upper/Lower Body Wingates And Handgrip Performance, Thomas Andre, Matt Green, Joshua Gann, Eric O'Neal, Tom Coates
International Journal of Exercise Science
International Journal of Exercise Science 8(3): 243-255, 2015. Caffeine enhances aerobic performance, but research is equivocal regarding anaerobic performance. This study examined effects of caffeine (7 mg/kg) on anaerobic performance in anaerobically active males (n = 10). Participants completed counterbalanced, double blind caffeine (Caf) and placebo (Pl) trials including a) 6 x 15 s upper body Wingates (UWant), b) 6 x 15 s lower body Wingates (LWant) and c) 6 x15 s maximal effort static hand grip test (HG) with 3 min recovery between bouts, 30 min between exercises. Peak power (Ppeak), mean power …
Thermal Performance Covaries With Environmental Temperature Across Populations Of Atlantic Salmon (Salmo Salar), Kayla J. Harding Gradil
Thermal Performance Covaries With Environmental Temperature Across Populations Of Atlantic Salmon (Salmo Salar), Kayla J. Harding Gradil
Electronic Thesis and Dissertation Repository
Global climate change is projected to have widespread effects that could threaten the viability of natural populations. Physiological processes of aquatic ectotherms critically depend on their thermal environment, such that the optima for performance often correspond to environmental temperatures. Given predicted changes in aquatic thermal environments, it is increasingly important to understand organism’s underlying physiological mechanisms utilized to cope with these changes. Here, I show that three populations of Atlantic salmon (Salmo salar) are narrowly adapted to their native summer temperatures, such that thermal tolerance is optimized near average temperatures and collapses near peak temperatures. Further, I found …
Effects Of A Smart-Phone Application On Psychological, Physiological, And Performance Variables In College-Aged Individuals While Running, Martin J. Moran, John M. Coons
Effects Of A Smart-Phone Application On Psychological, Physiological, And Performance Variables In College-Aged Individuals While Running, Martin J. Moran, John M. Coons
International Journal of Exercise Science
International Journal of Exercise Science 8(2) : 104-111, 2015. The purpose of this study was to determine the effects of auditory exergaming through the use of a smart-phone app called Zombies, Run! on psychological, physiological, and performance variables in college-aged individuals while running. Participants included both males (n = 10) and females (n = 10). Participants ran three 15 minute trials, after which they completed motivational questionnaires regarding inspiration, enjoyment, confidence, and anxiety levels. The first run got the participants accustomed to the application. The second and third were randomly counterbalanced either using the application again or running with no …
The Effects Of Skill Level On Distance And Heart Rate In Collegiate Tennis Players, Sanio Dizdarevic, Erika Deike
The Effects Of Skill Level On Distance And Heart Rate In Collegiate Tennis Players, Sanio Dizdarevic, Erika Deike
International Journal of Exercise Science: Conference Proceedings
The purpose of this experiment was to evaluate if skill level affects distance traveled and heart rate in tennis players in a collegiate match. Previous studies using professional tennis players have shown an increased distance for higher skill level players. Therefore, it was hypothesized that the higher level group would travel further in a match and have higher heart rates than the lower level group. Men (N=6) and women (N=6) from the TLU tennis team were observed for this experiment. Subjects were placed into either a higher level group (Group A) or a lower level group (Group B), based on …
