Racial Comparisons In Police Officer Bench Press Strength Over 12.5 Years, Robert W. Boyce, Tyler K. Willett, Glenn R. Jones, Edward L. Boone

International Journal of Exercise Science

International Journal of Exercise Science 7(2) : 140-151, 2014. Strength, when considering gender and race, provides a basis for training, hiring, and retention for police officers. The purpose of this study is to identify muscular strength differences among racial groups from initial-recruit to in-service tests. Strength variables included bench press, bench press/lean mass and bench press/body mass. Scores were retrieved for the 1990 to 1995 recruit classes and were paired to the 2006 in-service fitness log. Sample included 309 officers: 30 females (13 black, 17 white) and 279 males (41 black, 238 white). Mean age of recruit was 24.6 ± …

Anatomy And Physiology Preparatory Course Textbook (2nd Edition), Carlos Liachovitzky

Open Educational Resources

The goal of this preparatory textbook is to give students a chance to become familiar with some terms and some basic concepts they will find later on in the Anatomy and Physiology course, especially during the first few weeks of the course.

Organization and functioning of the human organism are generally presented starting from the simplest building blocks, and then moving into levels of increasing complexity. This textbook follows the same presentation. It begins introducing the concept of homeostasis, then covers the chemical level, and later on a basic introduction to cellular level, organ level, and organ system level. This …

Head And Neck Embryology: An Overview Of Development, Growth And Defect In The Human Fetus, Allison Baylis

Honors Scholar Theses

The purpose of this research is to explore the growth and formation of the head and neck from embryological development through puberty in order to understand how this knowledge is necessary for the development of dental and medical treatments and procedures. This is a necessary aspect of the medical and dental school curriculum at the University of Connecticut Health Center Schools of Medicine and Dental Medicine that needs to be incorporated into the current study of embryology for first-year students. Working with Dr. Christine Niekrash, D.M.D, this paper will cover the embryology and growth of the head, face and oral …

Fisiología De La Acidosis Ruminal Y Sus Implicaciones En La Producción Animal, Javier Humberto Campos Cuellar

Zootecnia

El rápido crecimiento de la industria ganadera, está ejerciendo una presión cada vez mayor en los recursos naturales. Se demanda mayor conocimiento de tecnologías y procedimientos que mejoren la eficacia en el cuidado de la dieta de los animales, no solo para evitar pérdidas en los hatos, sino para precisar las causas que pueden originar o colocar en riesgo a los animales de contraer patologías que puedan llevarlos a la muerte, una de ellas, es la acidosis ruminal. Por lo tanto, el trabajo se orientó al análisis de la acidosis ruminal, sus causas, prevención, manejo y las implicaciones en la …

Accuracy Of The Omron Hbf-500 Body Composition Monitor In Male And Female College Students, Michael I. Pribyl, John D. Smith, G Richard Grimes

International Journal of Exercise Science

The Omron HBF-500 is an inexpensive body composition monitor that incorporates both hand-to-hand and foot-to-foot electrical impedance technology. At this time, studies examining the accuracy of the HBF-500 when estimating percent body fat (%BF) are scarce and if this instrument gains popularity due to its claimed precision, comparisons against validated techniques should be conducted. The purpose of this study was to assess the accuracy of the Omron HBF-500 body composition monitor using the BOD POD as a criterion. Forty-eight men and 33 women participated in the study (24.3±6.9 years, 171.0±10.0 cm, 78.4±18.0 kg, 26.6±5.1 kg/m2). Participants were asked to refrain …

Differences Between Men And Women In Percentage Of Body Weight Supported During Push-Up Exercise, Constance M. Mier, Tal Amasay, Steven Capehart, Heather Garner

International Journal of Exercise Science

International Journal of Exercise Science 7(2) : 161-168, 2014. The purpose of this study was to investigate the effects of push-up method (standard vs modified) and gender on percentage of body weight supported. Thirty seven men and women completed five push-ups in the standard (SPU) and modified (MPU) positions, and 5-sec hold (static) in the up (elbow extension) and down (elbow flexion) positions. Vertical ground reaction forces (expressed as load relative to body weight) were measured using force platforms. From a video-captured image, a computer software distance tool measured vertical range of motion (ROM) achieved in the down position expressed …

Wrist-Worn Physical Activity Trackers Tend To Underestimate Steps During Walking, Tiffany Sears, Elmer Alvalos, Samantha Lawson, Ian Mcalister, L. Chris Eschbach, Jennifer Bunn

International Journal of Exercise Science

International Journal of Exercise Science 10(5): 764-773, 2017. The purpose of this study was to determine step-count accuracy of pedometers at different walking speeds. Ten recreationally active participants walked at five treadmill speeds (0.89, 1.11, 1.34, 1.56, and 1.79 m/s) for five minutes while wearing four wrist-worn activity trackers (Fitbit Charge HR®, Garmin Vivosmart HR®, Apple iWatch®, Jawbone UP3®) and the hip-worn Digi-Walker®. Each step was manually counted by a research technician (benchmark). Total step count at each speed was obtained for each device and compared to the benchmark using one-way MANOVA and Pearson correlation coefficient. For all five speeds, …

Body Image As A Motivator And Barrier To Exercise Participation, Laura R. Brudzynski*, William Ebben‡

International Journal of Exercise Science

Int J Exerc Sci 3(1): 14-24, 2010. This study examined self-reported relationships between motivations and barriers to exercise, frequency of exercise, and location of exercise to body image. The study surveyed 1044 students from a large Midwestern university. Respondents comprised of 689 (66.0%) females and 355 (34.0%) males with an age range of 17-55 years. Raw survey data were analyzed using independent content analysis. Most participants (76.8%) reported exercising while the remainder did not. Body image was a significant factor in determining the amount exercised for a majority of participants (58.3%), as well as the location of exercise for some …

The Relationship Between Cognition, Preseason Hitting Assessments, And In-Game Batting Performance In Collegiate Baseball And Softball Players, Amanda Carrol, Tonya Krupp, Kara Tucker, Nicholas J. Siekirk, Bradley J. Kendall

International Journal of Exercise Science

International Journal of Exercise Science 16(6): 23-30, 2023. Successful hitting performance may be related to perceptual processing of visual information. The purpose of this investigation was to examine the relationship between preseason cognitive assessments, off-field preseason hitting assessment, and in-game batting performing in collegiate baseball and softball athletes. Collegiate varsity baseball (n = 10, 20.5 ± 1.0 years) and softball (n = 16, 20.3 ± 1.3 years) underwent Flanker Task and Trail Maker Tests A (TMT-A) and B (TMT-B) 24 hours prior to a pre-seasoning indoor hitting assessment. During pre-season hitting assessment, athletes selected 10 underhand pitches and …
