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 …


Integrating The Functional Movement Screen ® Into Strength And Conditioning Programs, Quincy Johnson, Chantel C. Coleman, Timothy Baghurst Apr 2020

Integrating The Functional Movement Screen ® Into Strength And Conditioning Programs, Quincy Johnson, Chantel C. Coleman, Timothy Baghurst

Topics in Exercise Science and Kinesiology

  • The purpose of this article is to provide an overview of the Functional Movement Screen (FMS®) and how it can be integrated into strength and conditioning programs of all levels.
  • We utilized current literature and previous FMS ® field experience to develop and recommend approaches for implementing FMS® protocols into strength and conditioning programs.
  • Description of FMS® Movements: The FMS® is a comprehensive biomechanical efficiency screen which is comprised of seven movements that have been deemed fundamental to athletic performance (7). Those movements include the; deep squat, hurdle step, in-line lunge, shoulder mobility, active straight-leg raise, trunk stability push-up, and …

Mota

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 Apr 2020

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 …


The Effect Of Static Stretching On Proprioception, Pennation Angle, And Muscle Power Production, Lacey G. Dennis, Eva Alyss Blais, Kolyse E. Wagstaff, Li Li, Duke Biber Feb 2020

The Effect Of Static Stretching On Proprioception, Pennation Angle, And Muscle Power Production, Lacey G. Dennis, Eva Alyss Blais, Kolyse E. Wagstaff, Li Li, Duke Biber

Department of Health Sciences and Kinesiology Faculty Publications

With widespread use of pre-exercise stretching methods across sport and exercise, recent studies have questioned the effectiveness of such methods (Kay & Blazevich 2012; Cramer et al., 2005; Curry, Chengkalath, Crouch, Romance, & Manns, 2009). The purpose of this study was to examine how the relationship between pennation angle, proprioception, and muscle power are influenced by a static stretching protocol. Participants (n = 17) from a southeastern university in the United States consented to participate and were divided into an experimental group (n = 12) and control group (n = 5). The experimental group engaged in static stretched by placing …


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 Jan 2020

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, …

When Task Constraints Delimit Movement Strategy: Implications For Isolated Joint Training In Dancers, Paige E. Rice, Sophia Nimphius Jan 2020

When Task Constraints Delimit Movement Strategy: Implications For Isolated Joint Training In Dancers, Paige E. Rice, Sophia Nimphius

Research outputs 2014 to 2021

Athletic performance is determined by numerous variables that cannot always be controlled or modified. Due to aesthetic requirements during sports such as dance, body alignment constrains possible movement solutions. Increased power transference around the ankle-joint, coupled with lower hip-joint power, has become a preferential strategy in dancers during leaps and may be considered a dance-specific stretch-shortening cycle (SSC) demand. Newell's theoretical model of interacting constraints includes organismic (or individual), environmental, and task constraints describing the different endogenous and exogenous constraints individuals must overcome for movement and athletic performance. The unique task constraints imposed during dance will be used as a …
