Harvest Of The Ipsilateral Hamstrings Does Not Result In Tibial Internal Rotation Strength And Endurance Insufficiencies For Patients 12 To 36 Months Post-Anterior Cruciate Ligament Reconstruction, Giampietro L. Vairo
International Journal of Exercise Science: Conference Proceedings
Ipsilateral hamstrings tendons harvest as a primary autograft for anterior cruciate ligament (ACL) reconstruction has become increasingly prevalent among orthopaedic surgeons. Though, limited evidence exists detailing ensuing knee joint performance capacity. Previous authors have reported that ipsilateral semitendinosus and gracilis (STG) harvest results in significant tibial internal rotation strength deficiencies for related patients (1,2). However, prior data in regards to this measure have been reported as absolute as opposed to relative indices of strength and have not produced endurance results. Therefore, our objective was to profile relative tibial internal rotation strength and endurance responses to STG harvest in ACL reconstructed …

Influence Of Differences In Exercise-Intensity And Kilograms/Set On Energy Expenditure During And After Maximally Explosive Resistance Exercise, Scott A. Mazzetti Ph.D., Christopher Wolff, Brittany Collins, Michael T. Kolankowski, Brittany Wilkerson, Matthew Overstreet, Troy Grube
International Journal of Exercise Science
With resistance exercise, greater intensity typically elicits increased energy expenditure, but heavier loads require that the lifter perform more sets of fewer repetitions, which alters the kilograms lifted per set. Thus, the effect of exercise-intensity on energy expenditure has yielded varying results, especially with explosive resistance exercise. This study was designed to examine the effect of exercise-intensity and kilograms/set on energy expenditure during explosive resistance exercise. Ten resistance-trained men (22±3.6 years; 84±6.4 kg, 180±5.1 cm, and 13±3.8 %fat) performed squat and bench press protocols once/week using different exercise-intensities including 48% (LIGHT-48), 60% (MODERATE-60), and 72% of 1-repetition-maximum (1-RM) (HEAVY-72), plus …

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 …

Load Carriage Distance Run And Pushups Tests: No Body Mass Bias And Occupationally Relevant, Paul M. Vanderburgh, Nicholas S. Mickley, Philip A. Anloague, Kimber Lucius
Health and Sport Science Faculty Publications
Recent research has demonstrated body mass (M) bias in military physical fi tness tests favoring lighter, not just leaner, service members. Mathematical modeling predicts that a distance run carrying a backpack of 30 lbs would eliminate M-bias. The purpose of this study was to empirically test this prediction for the U.S. Army push-ups and 2-mile run tests. Two tests were performed for both events for each of 56 university Reserve Offi cer Training Corps male cadets: with (loaded) and without backpack (unloaded). Results indicated signifi cant M-bias in the unloaded and no M-bias in the loaded condition for both events. …

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.
