Body composition in elite strongman competitors. J Strength Cond Res 34(12): 3326–3330, 2020—The purpose of this descriptive investigation was to characterize a group of elite strongman competitors to document the body composition of this unique population of strength athletes. Data were collected from eligible competitors as part of a health screening program conducted over 5 consecutive years. Imaging was acquired using dual-energy x-ray absorptiometry (DXA), providing total …

BACKGROUND: Electrophysiological studies show that reductions in power within the alpha band are associated with the Alzheimer's disease (AD) continuum. Physical activity (PA) is a protective factor that has proved to reduce AD risk and pathological brain burden. Previous research has confirmed that exercise increases power in the alpha range. However, little is known regarding whether other non-modifiable risk factors for AD, such as increased age or APOE ε4 carriage, alter the association between PA and power in the alpha band. METHODS: The relationship between PA and alpha band power was examined in a sample of 113 healthy adults using …

The Effect Of Training With Weightlifting Catching Or Pulling Derivatives On Squat Jump And Countermovement Jump Force-Time Adaptations, Timothy J. Suchomel, Shana M. Mckeever, John J. Mcmahon, Paul Comfort

The purpose of this study was to examine the changes in squat jump (SJ) and countermovement jump (CMJ) force-time curve characteristics following 10 weeks of training with either load-matched weightlifting catching (CATCH) or pulling derivatives (PULL) or pulling derivatives that included force- and velocity-specific loading (OL). Twenty-five resistance-trained men were randomly assigned to the CATCH, PULL, or OL groups. Participants completed a 10 week, group-specific training program. SJ and …

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 …

Readiness To Train: Return To Baseline Strength And Velocity Following Strength Or Power Training, Alexander Vernon, Christopher Joyce, Harry G. Banyard

Health Sciences Papers and Journal Articles

This study investigated the return to baseline of movement velocity and maximal strength following a strength-orientated session and power-orientated session in the free-weight back-squat performed with maximal concentric velocity. Fourteen strength-trained males completed a strength-orientated session (five sets of five repetitions @80% of a one-repetition maximum) and a power-orientated session (three sets of six repetitions @50% one-repetition maximum ) in a randomised order over two weeks (e.g. strength week 1, power week 2). The back-squat was then performed with loads of 20%, 40%, 60%, 80%, 90% and 100% one-repetition maximum at 24, 48, 72 and 96 h following the strength …

Listening To The Voices Of Community Health Workers: A Multilevel, Culture-Centered Approach To Overcoming Structural Barriers In U.S. Latinx Communities, Angela L. Palmer-Wackerly, Virginia Chaidez, Caitlyn Wayment, Jonathan Baker, Anthony Adams, Lorey A. Wheeler

Department of Nutrition and Health Sciences: Faculty Publications

Community Health Workers (CHWs) are often incorporated into efforts to reduce health disparities for vulnerable populations. However, their voices are rarely the focus of research when considering how to increase their job effectiveness and sustainability. The current study addresses this gap by privileging the voices of 28 CHWs who work with Latinx communities in Nebraska through in-depth, semi-structured interviews. Using a multilevel, Culture-Centered Approach (CCA) to Health Communication, we identified two key structural communication issues: (a) increasing language accommodation and (b) increasing (and stabilizing) network integration across three ecological levels of health behavior (individual, microsystem, and exosystem …

The Effects Of Caffeine On Early Second Half Sprint Performance In Ncaa Diii Women’S Soccer Players, David J. Granniss, Jessica W. Chow, Daniel A. Jaffe, Kristin M. Cannon, Jessica C. Brown, Deborah Vanlangen, Charity A. Byrum

Department of Exercise Science Faculty Publications

Objective

The purpose of this study was to examine the effects of caffeine on early second half sprint performance in 21 NCAA DIII women’s soccer players. The caffeine dosage attempted to approximate a liquid dosage many student athletes typically consume.

Design

In a randomized double blind repeated measures design, subjects began the protocol after ingestion of caplets containing 3 mg^.kg^-1 of caffeine (CAF) and after ingestion of placebo (PLA) caplets. Pre-game, warm-up, and first half conditions were designed to maximize external validity.

Methods

An adapted version of the Loughborough Intermittent Shuttle Test was applied to replicate first …

Absolute And Relative Strength, Power And Physiological Characteristics Of Indian Junior National-Level Judokas, Dale M. Harris, Kristina Kendall, G. Gregory Haff, Christopher Latella

Research outputs 2014 to 2021

The physical qualities that underpin successful junior judokas requires continuing investigation. We investigated the physical and physiological characteristics of junior national level judokas. We tested 25 (15 male, 10 female) Indian judokas for absolute and relative strength (back-squat and bench-press one-repetition maximum (1RM) as well as isometric handgrip), aerobic (RAMP test) and lower-body anaerobic power (Wingate 6-s sprint and countermovement jump), change-of-direction (5-0-5 test) and speed (30 m sprint). Athletes were grouped according to national-level competition placing (gold-medal winners (GM; n = 8), all medal winners (MW; n = 13), non-medallists (NM; n = 12), and NM plus silver and …
