Effects of an After-School Physical Activity Intervention on Physical Activity, Aerobic Fitness, and Body Composition
(East Carolina University, 2012)
Low levels of physical activity have been linked to the increased prevalence of obesity in children and adolescents. Federal and local policies to increase the focus on academic time have resulted in decreased physical ...
WORKSITE INTERVENTION TO REDUCE SEDENTARY TIME
(East Carolina University, 2012)
Background: Prevalence of sedentary occupations is on the rise and sedentary time is independently associated with an increased risk for chronic diseases. Interventions conducted in the work site have potential for reducing ...
Incorporating a visuomotor skill task with resistance training does not increase strength gains in healthy young adults
(East Carolina University, 2012)
Resistance training causes well-documented adaptations in the nervous system and increases maximal voluntary force of healthy human skeletal muscle in the trained and also of the same muscle in untrained limb. It is also ...
Control of Walking Speed in Young and Old Adults
(East Carolina University, 2012)
Walking is a basic form of locomotion and walking velocity is a good predictor of human health, with faster velocities indicating better health. While faster walking velocities have been attributed to overall increases ...
Integrated Primary Care : A Systematic Review of Study Design and Program Characteristics
(East Carolina University, 2012)
Integrated primary care (IPC), the integration of medical and behavioral health professionals, is a viable part of the solution for the United States' fragmented health care delivery system. Over the past decade or so, ...
REGULATION OF LIPOLYSIS BY [BETA]-ADRENERGIC ACTIVATION AND EXERCISE IN OBESE AFRICAN-AMERICAN AND CAUCASIAN WOMEN
(East Carolina University, 2012)
African-American women (AAW) are twice as likely to be obese as Caucasian women (CW); however, previous in-vitro studies have shown that AAW have higher densities of beta-adrenergic receptors (B-AR) in the subcutaneous ...
Child Development Knowledge and Human Factors in Toy Design : An Exploratory Study of Popular Children's Products
(East Carolina University, 2012)
Play reflects how children understand the world, and it also provides them with opportunities to learn and refine their social, emotional, motor, and problem-solving skills. Before designing a product such as a children's ...
Comparison of Scaled vs. Ultrasound Based Musculoskeletal Models on Knee Muscle Moments During Single-Leg Squatting
(East Carolina University, 2012)
Muscles produce force, resulting in moments about a joint, causing movement of the body. Muscle forces are estimated with a Hill-type model incorporating four parameters; optimal fiber length (OFL), tendon slack length, ...
Influence of training history and contraction velocity on hamstring muscle coactivation during maximal effort knee extension
(East Carolina University, 2012)
When a muscle produces voluntary force, muscles on the opposite side of the joint, the antagonists, are also activated. While coactivation of the knee flexors during knee extension is presumed to increase joint stability ...
VARIABILITY IN POPLITEAL ARTERY BLOOD FLOW : EFFECT OF EXERCISE TRAINING
(East Carolina University, 2012)
Mean arterial pressure (MAP) is regulated through changes in cardiac output (Q) and total peripheral resistance (TPR), where Q = heart rate (HR) x stroke volume (SV). Healthy heart rhythms have inherent variability and a ...
