The Impact Of External Loads Carried By Police Officers On Vertical Jump Performance, Amy Wiley, Aaron Joseph, Robin Marc Orr, Ben Schram, Charles Kornhauser, Ryan J. Holmes, J. Jay Dawes
International Journal of Exercise Science
International Journal of Exercise Science 13(6): 1179-1189, 2020. The purpose of this study was to examine the impact that external loads have on vertical jump height and peak anaerobic power output (PAPw) of police officers during a vertical jump (VJ) test. Retrospective data of 47 (mean age 38.79 ± 7.97 years) police officers from a US Law Enforcement Agency (LEA) were used for analysis. VJ heights and body mass were used in the Sayers Peak Power Equation to calculate PAPw. Power-to-weight (P:W) ratios were then calculated by dividing PAPw by the officer’s body mass. VJ height significantly (p < .001) decreased with load (unloaded = 49.49 ± 8.46 cm: loaded = 43.62 ± 7.68 cm). A Pearson’s correlation showed a significant (p …

International Journal of Exercise Science
International Journal of Exercise Science 13(1): 723-733, 2020. The assessment of neuromuscular fatigue is important for minimizing the risks of nonfunctional overreaching, and monitoring training loads has rapidly grown in recent years. The objective of the study was to compare the acute upper body performance and rating of perceived exertion (RPE) responses to high-volume (HV) and high-intensity (HI) resistance-training loads. Sixteen young resistance-trained men (4 repetition maximum [RM] bench press = 105.8 ± 15.9 kg) were divided into two groups of eight subjects each that performed a HI (3 sets of 4RM with 180 s of rest), and a HV …
Comparison Of Post-Activation Potentiating Stimuli On Jump And Sprint Performance, Aaron D. Piper, Dustin P. Joubert, Eric J. Jones, Malcolm T. Whitehead
Comparison Of Post-Activation Potentiating Stimuli On Jump And Sprint Performance, Aaron D. Piper, Dustin P. Joubert, Eric J. Jones, Malcolm T. Whitehead
International Journal of Exercise Science
International Journal of Exercise Science 13(4): 539-553, 2020. Post-activation potentiation (PAP) is a phenomenon characterized by improved muscle performance based on the previous contractile activity of the muscle. The purpose of this study was to determine the effect of different potentiating stimuli on jump and sprint performance in 13 resistance trained, college-aged men and women. After determining back squat 1 repetition max, subjects returned for testing on separate days to complete one of four interventions (dynamic resistance, weighted plyometric, isometric, or control) in a randomized order. A standardized warmup was performed, followed by a baseline countermovement jump (CMJ) and 20m …
In-Season Hip Thrust Vs. Back Squat Training In Female High School Soccer Players, Nicole A. Millar, Lauren M. Colenso-Semple, Robert G. Lockie, Risto H.J. Marttinen, Andrew J. Galpin
In-Season Hip Thrust Vs. Back Squat Training In Female High School Soccer Players, Nicole A. Millar, Lauren M. Colenso-Semple, Robert G. Lockie, Risto H.J. Marttinen, Andrew J. Galpin
International Journal of Exercise Science
International Journal of Exercise Science 13(4): 49-61, 2020. The barbell back squat provides a highly effective training stimulus to improve lower body strength, speed, and power, which are considered key components of athletic performance in many sports. The barbell hip thrust exercise utilizes similar musculature, and is popular among practitioners, but has received far less scientific examination. The purpose of this study was to evaluate the effects of an in-season resistance training program with hip thrusts or back squats on physical performance in adolescent female soccer players. Fourteen players completed identical whole-body resistance training twice per week for 6 weeks, …
