Countermovement Jump And Squat Jump Force-Time Curve Analysis In Control And Fatigue Conditions, Steven Hughes, John Warmenhoven, G. Gregory Haff, Dale W. Chapman, Sophia Nimphius

Research outputs 2014 to 2021

This study aimed to reanalyze previously published discrete force data from countermovement jumps (CMJs) and squat jumps (SJs) using statistical parametric mapping (SPM), a statistical method that enables analysis of data in its native, complete state. Statistical parametric mapping analysis of 1-dimensional (1D) force-time curves was compared with previous zero-dimensional (0D) analysis of peak force to assess sensitivity of 1D analysis. Thirty-two subjects completed CMJs and SJs at baseline, 15 minutes, 1, 24, and 48 hours following fatigue and control conditions in a pseudo random cross-over design. Absolute (CMJ_ABS/SJ_ABS) and time-normalized (CMJ_NORM/SJ_NORM) …

Myokine Expression And Tumor-Suppressive Effect Of Serum Following 12 Weeks Of Exercise In Prostate Cancer Patients On Adt, Jin-Soo Kim, Rebekah Louise Wilson, Dennis Taaffe, Daniel A. Galvao, Elin S. Gray, Robert Newton

Research outputs 2014 to 2021

Purpose:

Although several mechanisms have been proposed for the tumor-suppressive effect of exercise, little attention has been given to myokines, even though skeletal muscle is heavily recruited during exercise resulting in myokine surges. We measured resting serum myokine levels before and after an exercise-based intervention and the effect of this serum on prostate cancer cell growth.

Methods:

Ten prostate cancer patients undertaking androgen deprivation therapy (age, 73.3 ± 5.6 yr) undertook a 12-wk exercise-based intervention including supervised resistance training, self-directed aerobic exercise, and protein supplementation. Body composition was assessed by dual-energy x-ray absorptiometry and muscle strength by the one-repetition maximum …
