Relationship Between One Repetition Maximum Strength And Peak Power Output For The Free-Weight Bench Press Exercise, Ibrahim K. Munayer, Matt S. Stock, Micheal J. Luera, Jocarol E. Shields

International Journal of Exercise Science: Conference Proceedings

Strength and conditioning coaches are often interested in improving power output in their athletes. As many coaches are aware that power is the product of force and velocity, an emphasis is often placed on training with loads that correspond to peak mechanical power output (e.g., 30-50% of the one repetition maximum [1RM]). The purpose of this study was to examine the relationship between 1RM strength and peak power output during the free-weight bench press exercise. Twenty-one healthy, recreationally resistance-trained men (mean ± SD age = 24 ± 3 years; body mass = 90.5 ± 14.6 kg; 1RM bench press = …

Effects Of Diverting Activities On Recovery From Repeated Maximum Voluntary Contractions, Micheal J. Luera, Matt S. Stock, Jocarol E. Shields, Ibrahim K. Munayer

International Journal of Exercise Science: Conference Proceedings

Previous investigations have demonstrated that diverting activities (e.g., contralateral exercise and pinching one’s fingers together) can minimize the severity of muscle fatigue that occurs during exercise. In addition to their ability to resist fatigue during exercise, diverting activities may help subjects recover between work bouts. The purpose of this study was to examine the effects of mental and physical diverting activities on recovery from fatiguing isometric muscle actions. On three separate occasions, twelve men (mean ± SD age = 22 ± 1 years) and nine women (age = 22 ± 2 years) performed ten repeated, ten-second isometric maximum voluntary contractions …

Exercise Knowledge, Exercise Beliefs, Physical Activity Engagement And Physical Function In Older Adults, Nicole E. Priest, Amy M. White, James B. Geeslin, Matthew J. Garver, Libby E. Mccurley

International Journal of Exercise Science: Conference Proceedings

Historically, recall surveys have been used to gather information about exercise knowledge and beliefs (EKB) and physical activity (PA). There seems to be a disconnect between what people know and believe about exercise and the choices they make about engaging in exercise. Advancements in the capacity to capture verifiable PA data have greatly improved with application of accelerometers. The ability to objectively verify PA makes reexamining the relationship between EKB and both PA and physical function (PF) worthwhile. The aim of this investigation was to revisit the relationship between EKB and PA and PF in older adults using recall surveys …

International Journal of Exercise Science: Conference Proceedings

Acclimatization to altitude can improve endurance performance above levels achieved solely by training at sea level. There is natural limitation in the applicability of employing terrestrial altitude training – namely proximity. A simple, non-cumbersome method of simulating altitude is desirable to many types of endurance athletes. The Alto2Lab (Pharma Pacific Inc.), consisting of primarily a breathing tube and silo stack, has shown some potential in this role. There is a lack of evidence regarding whether simulated altitude exposure triggers abnormal cardiovascular responses. The aim of this study was to provide initial evidence of cardiac changes associated with usage patterns that …
