In today's uncertain market and continuously evolving technology, managing manufacturing systems are more complex than ever. This paper studies the dynamics of managing variety and volume to enhance value creation in manufacturers implementing system level advanced and automated manufacturing technology (AAM1). The demand is composed of heterogeneous customers who make purchasing decisions depending on the variety levels and lead times of the firm's product offerings. The cost structure adopted calculates profit as the difference between customer value creation rate (VCR) and costs associated with the process of creating this value. Reported results contribute to the variety and volume management literature …

An Experimental Approach To Study Individual Differences In Infants' Intake And Satiation Behaviors During Bottle-Feeding, Alison K. Ventura, Julie A. Mennella

Kinesiology and Public Health

Background: As a group, bottle-fed infants are at higher risk for rapid weight gain compared with breast-fed infants. However, little is known about individual differences in feeding behaviors of bottle-feeding infants, as well as maternal and infant characteristics associated with bottle-feeding outcomes.

Methods: We conducted a 2-day, within-subject study of 21 formula-feeding dyads; the within-subject factor was feeding condition: mother-led (ML; mothers were given the instruction to feed their infants as they typically would) vs. infant-led (IL; the experimenter ensured feeding began when infants signaled hunger and ended when they rejected the bottle on three consecutive occasions). Intake was determined …

Purpose: The purpose of this study was to determine breathing efficiency during increasing levels of submaximal aerobic exercise. Methods: Nineteen individuals (males N=9, females N=10) completed a test for maximal oxygen consumption (VO2max) and on separate days 4-min treadmill runs at increasing submaximal intensities (50%, 65%, and 80% of VO2max) under conditions of oral breathing or nasal breathing. Respiratory (respiration rate [RR], pulmonary ventilation [VE]), metabolic (oxygen consumption [VO2], carbon …

Mastoid Vibration Affects Dynamic Postural Control During Gait In Healthy Older Adults, Jung Hung Chien, Mukul Mukherjee, Jenny Kent, Nick Stergiou

Journal Articles

Vestibular disorders are difficult to diagnose early due to the lack of a systematic assessment. Our previous work has developed a reliable experimental design and the result shows promising results that vestibular sensory input while walking could be affected through mastoid vibration (MV) and changes are in the direction of motion. In the present paper, we wanted to extend this work to older adults and investigate how manipulating sensory input through mastoid vibration (MV) could affect dynamic postural control during walking. Three levels of MV (none, unilateral, and bilateral) applied via vibrating elements placed on the mastoid processes were combined …

Cognitive And Movement Measures Reflect The Transition To Presence-At-Hand, Dobromir Dotov, Lin Nie, Kevin Wojcik, Anastasia Jinks, Xiaoyu Yu, Anthony Chemero

Journal Articles

The phenomenological philosopher Martin Heidegger's proposed transition from readiness-to-hand to presence-at-hand and the hypothesis of extended cognition were addressed empirically in an experiment on tool use. It involved a video game of steering erratically moving objects to a target while performing a secondary cognitive task. A strong perturbation of the hand-pointer linkage in the video game induced the transition from ready-to-hand to present-at-hand. In Experiment 1, this perturbation resulted in decreased motor performance and improved recall of task-irrelevant features. Experiment 2 replicated these results and addressed additional questions. Measures of movement variability based on the multifractal formalism confirmed the …

A General Relationship Links Gait Mechanics And Running Ground Reaction Forces, Kenneth P. Clark, Laurence J. Ryan, Peter G. Weyand

Kinesiology Faculty Publications

The relationship between gait mechanics and running ground reaction forces is widely regarded as complex. This viewpoint has evolved primarily via efforts to explain the rising edge of vertical force– time waveforms observed during slow human running. Existing theoretical models do provide good rising-edge fits, but require more than a dozen input variables to sum the force contributions of four or more vague components of the body’s total mass (mb). Here, we hypothesized that the force contributions of two discrete body mass components are sufficient to account for vertical ground reaction force– time waveform patterns in full (stance foot and …

Rates Of Performance Loss And Neuromuscular Activity In Men And Women During Cycling: Evidence For A Common Metabolic Basis Of Muscle Fatigue, Christopher W. Sundberg, Sandra K. Hunter, Matthew W. Bundle

Exercise Science Faculty Research and Publications

The durations that muscular force and power outputs can be sustained until failure fall predictably on an exponential decline between an individual’s 3-s burst maximum to the maximum performance they can sustain aerobically. The exponential time constants describing these rates of performance loss are similar across individuals, suggesting that a common metabolically based mechanism governs muscle fatigue; however, these conclusions come from studies mainly on men. To test whether the same physiological understanding can be applied to women, we compared the performance-duration relationships and neuromuscular activity between seven men [23.3 ± 1.9 (SD) yr] and seven women (21.7 ± 1.8 …

The Accuracy Of Pedometers In Measuring Walking Steps On A Treadmill In College Students, Hannah M. Husted, Tamra Llewellyn

International Journal of Exercise Science

International Journal of Exercise Science 10(1): 146-153, 2017. Pedometers are a popular way for people to track if they have reached the recommended 10,000 daily steps. Therefore, the purpose of this study was to determine the accuracy of four brands of pedometers at measuring steps, and to determine if a relationship exists between pedometer cost and accuracy. The hypothesis was that the more expensive brands of pedometers (the Fitbit Charge™ and Omron HJ-303™) would yield more accurate step counts than less expensive brands (the SmartHealth – Walking FIT™ and Sportline™). While wearing all pedometers at once, one male and eleven …

The Effect Of High Intensity Interval Run Training On Cross Sectional Area Of The Vastus Lateralis In Untrained College Students, Rebekah Estes, David Thrush, Amy Malinowski, Meredith Piacentini, Eric Salley, Cassidy Losey, Erik Hayes

International Journal of Exercise Science

International Journal of Exercise Science 10(1): 137-145, 2017 Aerobic cycling has been repeatedly shown to induce hypertrophy in skeletal muscle across a variety of populations, while there has been a lack of investigation into the impact of running upon hypertrophy. An increasingly popular model of aerobic exercise is high-intensity interval training (HIIT); in addition to its positive impact upon cardiovascular health, HIIT may be sufficient for inducing significant muscular hypertrophy. Therefore, the purpose of this investigation was to examine the influence of a high-intensity interval running protocol upon hypertrophy of the vastus lateralis in an untrained, young population. Twelve recreationally …

Effects Of Simulated Altitude On Maximal Oxygen Uptake And Inspiratory Fitness, Nicole Biggs, Benjamin England, Nicole Turcotte, Melissa R. Cook, Alyne L. Williams

International Journal of Exercise Science

International Journal of Exercise Science 10(1): 128-136, 2017 Aerobic exercise at altitude has shown an increase in maximal oxygen uptake. Similar effects have been replicated by way of simulated altitude training, which have influenced various advances in the field of exercise science. Elevation Training Masks© (ETM) claim to stimulate cardiorespiratory fitness improvements similar to training at altitude, however, there is little research to support this claim. The purpose of this study was to research the effect that a hypoxia-inducing mask would have on cardiorespiratory fitness and pulmonary function through the use of a high intensity interval training (HIIT) running program. …

Meeting Usdhhs Physical Activity Guidelines And Health Outcomes, E. Earlynn Lauer, Allen W. Jackson, Scott B. Martin, James R. Morrow Jr.

International Journal of Exercise Science

International Journal of Exercise Science 10(1): 121-127, 2017 Current public health physical activity (PA) guidelines suggest ≥500 METmin/week of PA, with additional benefits beyond 1000 METmin/week (i.e., a dose response). Revised U.S. PA guidelines are scheduled for 2018. The purpose was to relate health markers (blood pressure, percent fat, BMI, blood glucose, cholesterol, and cardiorespiratory fitness) to verify the dose response for PA guidelines revision. 505 non-smoking participants self-reported PA behaviors and completed medical screening. MANCOVA controlling for age and gender determined the relation between health markers and PA. MANCOVA indicated significantly (P<.001) different health markers of percent fat, BMI, glucose, and treadmill time as a function of PA. Post-hoc Helmert contrasts (1] <500 METmin/week vs. ≥500 METmin/week and 2] 500 to <1000 METmin/week vs. ≥1000 METmin/week) indicated that meeting the PA guidelines was associated with better health markers and higher cardiorespiratory fitness. Effect sizes were greater for contrast 1 than for contrast 2, suggesting a plateauing effect. Revised public health guidelines should consider achievement of ≥500 METmin/week to be most important, with additional modest gain thereafter. Revised PA guidelines should stress the importance of achieving 500-1000 METmin/week.

Borg Scale Is Valid For Ratings Of Perceived Exertion For Individuals With Parkinson’S Disease, Amanda Penko

International Journal of Exercise Science

International Journal of Exercise Science 10(1): 76-86, 2017. Parkinson’s disease is a neurodegenerative disease that has traditionally been treated with anti-parkinsonian medication. There is increasing evidence that exercise is beneficial to those with PD, therefore, it is necessary to validate a measure of exertion that can be implemented across exercise settings that may not have the capability to actively monitor heart rate. The aim of this project was to determine the validity of the Borg RPE scale in individuals with PD undergoing a maximal progressive cycling exercise test. Thirty-eight males and females (58.5 ± 8.1 yrs) with a clinical diagnosis …

International Journal of Exercise Science

International Journal of Exercise Science 10(1): 62-75, 2017. Energy ratings have been used as a marker of exercise readiness (i.e. pre-exercise physical/mental state indicating ability to perform) within flexible nonlinear periodization (FNLP)-based resistance training interventions. However, empirical data is lacking regarding the utility of this approach for aerobic exercise. The purpose of this study was to examine the ability of pre-exercise energy level to predict affective and behavioral responses to prescribed aerobic exercise. Participants consisted of 19 women and 8 men (N=27, age=20±4 years, estimated maximal oxygen uptake=37±6). Participants performed two 30-min bouts of treadmill exercise under an imposed moderate …

The Acute Effects Of Static Stretching Compared To Dynamic Stretching With And Without An Active Warm Up On Anaerobic Performance, Bradley J. Kendall

International Journal of Exercise Science

International Journal of Exercise Science 10(1): 53-61, 2017. The Wingate Anaerobic Test (WAnT) has been used in many studies to determine anaerobic performance. However, there has been poor reporting of warm-up protocols and limited consistency between warm-up methods that have been used. With the WAnT being such a commonly-used test, consistency in warm-up methods is essential in order to compare results across studies. Therefore, this study was designed to compare how static stretching, dynamic stretching, and an active warm-up affect WAnT performance. Ten recreationally active participants (5 males, 5 females) with a mean (SD) age of 23.3 (0.7) volunteered for …

The Effect Of Military Load Carriage On Postural Sway, Forward Trunk Lean, And Pelvic Girdle Motion, Eileen M. Strube, Andrea Sumner, Roger O. Kollock Jr, Kenneth E. Games, Marie A. Lackamp, Masahiro Mizutani, Joellen M. Sefton

International Journal of Exercise Science

International Journal of Exercise Science 10(1): 25-36, 2017. Musculoskeletal injuries are a common occurrence in military service members. It is believed that the load carried by the service member impedes stability and alters back and pelvis kinematics, increasing their susceptibility to musculoskeletal injuries, specifically in the lower extremities. The purpose of this study was to examine the effects of two different loads on postural sway, forward trunk lean, and pelvic girdle motion in United States Army Cadets. Twenty male Army Reserve Officers’ Training Corps Cadets participated in this study. Each participant performed the Modified Clinical Testing of Sensory Interaction (mCTSIB) …

Sport Commitment Among Adult Recreational Soccer Players: Test Of An Expanded Model, Amanda L. Frayeh, Beth Lewis

International Journal of Exercise Science

International Journal of Exercise Science 10(1): 4-24, 2017. Adult sport leagues provide opportunities for physical activity (PA), but little is known about adults’ commitment to recreational sports. We proposed two expanded versions of Scanlan and colleagues’ sport commitment model (SCM) to explore psychosocial factors related to adults’ participation in these leagues. Model 1 proposed athletic identity and social cohesion as additional predictors of commitment. Previous research found these variables to be positively related to commitment, but had not systematically examined them within the context of the SCM. We also explored participation in moderate-to-vigorous physical activity (MVPA) as a behavioral manifestation …
