Seventeen strength and power athletes (n = 11 males, 6 females; height: 177.5 ± 7.0 cm, 165.8 ± 11.4 cm; body mass: 90.0 ± 14.1 kg, 66.4 ± 13.9 kg; age: 30.6 ± 10.4 years, 30.8 ± 8.7 years), who regularly performed weightlifting movements during their resistance training programs, were recruited to examine the effect of altering body posture and barbell position on the between-session reliability of force-time characteristics generated in the isometric mid-thigh pull (IMTP). After participants were familiarised with the testing protocol, they undertook two testing sessions which were separated by seven days. In each session, the participants …

Repetition-To-Repetition Differences Using Cluster And Accentuated Eccentric Loading In The Back Squat, John P. Wagle, Christopher B. Taber, Aaron J. Cunanan, Matt L. Sams, Alexander Wetmore, Garett E. Bingham, Brad H. Deweese, Kimitake Sato, Charles A. Stuart, Michael H. Stone Jul 2018

Repetition-To-Repetition Differences Using Cluster And Accentuated Eccentric Loading In The Back Squat, John P. Wagle, Christopher B. Taber, Aaron J. Cunanan, Matt L. Sams, Alexander Wetmore, Garett E. Bingham, Brad H. Deweese, Kimitake Sato, Charles A. Stuart, Michael H. Stone

Exercise Science Faculty Publications

The current investigation was an examination of the repetition-to-repetition magnitudes and changes in kinetic and kinematic characteristics of the back squat using accentuated eccentric loading (AEL) and cluster sets. Trained male subjects (age = 26.1 ± 4.1 years, height = 183.5 ± 4.3 cm, body mass = 92.5 ± 10.5 kg, back squat to body mass ratio = 1.8 ± 0.3) completed four load condition sessions, each consisting of three sets of five repetitions of either traditionally loaded straight sets (TL), traditionally loaded cluster sets (TLC), AEL cluster sets (AEC), and AEL straight sets where only the initial repetition had …

Monitoring tests are commonly used to assess weightlifter’s preparedness for competition. Although various monitoring tests have been used, it is not clear which test is the strongest indicator of weightlifting performance. Therefore, the purpose of this study was to (1) determine the relationships between vertical jump, isometric mid-thigh pull (IMTP) and weightlifting performance; and (2) compare vertical jumps to IMTP as monitoring tests of weightlifting performance in a large cohort of male and female weightlifters. Methods: Fifty-two competitive weightlifters (31 males, 21 females) participated in squat and countermovement jump testing (SJ, CMJ), and IMTP testing performed on force plates. All …


The Effect Of Maximal Isometric Training On Doublet-Induced Force Enhancement And Its Relationship With Changes In Voluntary Rate Of Force Development, David Vernon Murray Jan 2018

The Effect Of Maximal Isometric Training On Doublet-Induced Force Enhancement And Its Relationship With Changes In Voluntary Rate Of Force Development, David Vernon Murray

Theses: Doctorates and Masters

Motor unit double discharges (i.e. doublets), which are excitatory potentials that occur at shorter-than-normal intervals (e.g. 5-10 ms) during normal muscle activation, are known to cause muscle force to exceed that predicted from a standard, linear summation of twitch forces. However, although a marked increase in the occurrence of motor unit doublets at the onset of a contraction has been observed after explosive-type exercise training, and has been correlated with changes in RFD (Van Cutsem et al., 1998), little is known about the influence of strength training on the physiological and biomechanical benefits derived from the phenomenon. The present research …
