Treatment-Associated Changes In Body Composition, Health Behaviors, And Mood As Predictors Of Change In Body Satisfaction In Obese Women: Effects Of Age And Race/Ethnicity, Jim Annesi, Gisele A. Tennant, Nicole Mareno Nov 2014

Treatment-Associated Changes In Body Composition, Health Behaviors, And Mood As Predictors Of Change In Body Satisfaction In Obese Women: Effects Of Age And Race/Ethnicity, Jim Annesi, Gisele A. Tennant, Nicole Mareno

Jim Annesi

A lack of satisfaction with one’s body is common among women with obesity, often prompting unhealthy “dieting.” Beyond typically slow improvements in weight and body composition, behavioral factors might also affect change in body satisfaction. Age and race/ethnicity (African American vs. White) might moderate such change. Obese women (N = 246; M age = 43 years; M BMI = 39 kg/m2) initiating a 6-month cognitive-behaviorally based physical activity and nutrition treatment were assessed on possible predictors of body satisfaction change. At baseline, African American and younger women had significantly higher body satisfaction. The treatment was associated with significant within-group ...

Background:Previous research has shown exercise to be an effective method to mitigate many adverse treatment-related effects of androgen suppression therapy (AST) but the potential impact of exercise on sexual activity remains unknown. The purpose of this investigation was to report the effect of a 12-week exercise program on sexual activity in prostate cancer patients undergoing AST.Methods:Fifty-seven prostate cancer patients undergoing AST were randomly assigned to an exercise program (resistance and aerobic modes; n=29) or usual care control (n=28). Sexual activity was assessed by the European Organization for Research and Treatment of Cancer prostate cancer-specific quality ...


Exercise Therapy For Sexual Dysfunction After Prostate Cancer, Prue Cormie, Robert Newton, Dennis Taaffe, Nigel Spry, Daniel Galvao Nov 2014

Exercise Therapy For Sexual Dysfunction After Prostate Cancer, Prue Cormie, Robert Newton, Dennis Taaffe, Nigel Spry, Daniel Galvao

Prue Cormie

Sexual dysfunction is one of the most common, distressing and persistent adverse effects of prostate cancer treatment, and has a profound effect on quality of life for the patient and his partner. Current health-care provisions are inadequate to address the demand for the management of sexual dysfunction, with approximately half of prostate cancer survivors reporting unmet sexual health-care needs. Management strategies predominately involve pharmacological interventions to address the direct physiological effects of prostate cancer treatment on erectile function. However, the aetiology of sexual dysfunction is multifaceted and considerable physiological and psychological adverse effects of prostate cancer treatments, which are not ...


Knee Angle-Specific Emg Normalization: The Use Of Polynomial Based Emg-Angle Relationships, J Earp, R Newton, Prue Cormie, A Blazevich Nov 2014

Knee Angle-Specific Emg Normalization: The Use Of Polynomial Based Emg-Angle Relationships, J Earp, R Newton, Prue Cormie, A Blazevich

Prue Cormie

The normalization of EMG signals to those recorded during a maximal voluntary contraction provides a valid construct for comparisons of relative muscle activity. However, the length dependence of muscle activation and purported, substantial, muscle translocation and changes in muscle architecture during dynamic movements presents a need for joint angle-dependent normalization processes. The purposes of the present study were to: (1) quantify variations in muscle activity across a large ROM, (2) determine the accuracy with which fitted EMG-joint angle curves accurately characterized these variations, and (3) compare peak (EMG-P) and average (EMG-A) EMG amplitudes obtained during a countermovement leg extension when ...


Safety And Efficacy Of Resistance Exercise In Prostate Cancer Patients With Bone Metastases, Prue Cormie, Robert Newton, Nigel Spry, David Joseph, Dennis Taaffe, Daniel Galvao Nov 2014

Safety And Efficacy Of Resistance Exercise In Prostate Cancer Patients With Bone Metastases, Prue Cormie, Robert Newton, Nigel Spry, David Joseph, Dennis Taaffe, Daniel Galvao

Prue Cormie

Background:Due to concerns of fragility fracture, exercise is a perceived contraindication for prostate cancer patients with bone metastases. These patients experience significant functional impairment and muscle atrophy, which may lead to an increased likelihood of skeletal complications (i.e., pathological fracture, bone pain) and/or falls. Safe resistance exercise prescription may counteract this effect. The aim of this feasibility trial was to determine the safety and efficacy of resistance exercise by prostate cancer survivors with bone metastatic disease.Methods:Twenty men with established bone metastases secondary to prostate cancer were randomly assigned to a 12-week resistance exercise program in ...


Complexity-Based Measures Inform Tai Chi's Impact On Standing Postural Control In Older Adults With Peripheral Neuropathy, Brad Manor, Lewis A. Lipsitz, Peter M. Wayne, C-K Peng, Li Li Oct 2014

Complexity-Based Measures Inform Tai Chi's Impact On Standing Postural Control In Older Adults With Peripheral Neuropathy, Brad Manor, Lewis A. Lipsitz, Peter M. Wayne, C-K Peng, Li Li

Li Li

Background: Tai Chi training enhances physical function and may reduce falls in older adults with and without balance disorders, yet its effect on postural control as quantified by the magnitude or speed of center-of-pressure (COP) excursions beneath the feet is less clear. We hypothesized that COP metrics derived from complex systems theory may better capture the multi-component stimulus that Tai Chi has on the postural control system, as compared with traditional COP measures. Methods: We performed a secondary analysis of a pilot, non-controlled intervention study that examined the effects of Tai Chi on standing COP dynamics, plantar sensation, and physical ...


Practical Applications Of Biomechanical Principles In Resistance Training: Neuromuscular Factors And Relationships, Jason Lake, Paul A. Swinton, Justin Keogh Oct 2014

Practical Applications Of Biomechanical Principles In Resistance Training: Neuromuscular Factors And Relationships, Jason Lake, Paul A. Swinton, Justin Keogh

Justin Keogh

This paper is the second in our three part series examining how a variety of biomechanical principles and concepts have direct relevance to the prescription of resistance training for the general and athletic populations as well as for musculoskeletal injury rehabilitation. In this paper, we considered different neuromuscular characteristics of resistance exercise. We started by defining the causes of motion, discussing force and Newton’s second law of linear motion. This led to discussion of impulse, and how its relationship with momentum can be used to study force-time curves recorded from different ground-based resistance exercises. This enables the sports biomechanist ...

Ampk Activation: A Therapeutic Target For Type 2 Diabetes?, Kimberly A. Coughlan, Rudy Valentine, Neil B. Ruderman, Asish K. Saha Jun 2014

Ampk Activation: A Therapeutic Target For Type 2 Diabetes?, Kimberly A. Coughlan, Rudy Valentine, Neil B. Ruderman, Asish K. Saha

Rudy Valentine

Type 2 diabetes (T2D) is a metabolic disease characterized by insulin resistance, β-cell dysfunction, and elevated hepatic glucose output. Over 350 million people worldwide have T2D, and the International Diabetes Federation projects that this number will increase to nearly 600 million by 2035. There is a great need for more effective treatments for maintaining glucose homeostasis and improving insulin sensitivity. AMP-activated protein kinase (AMPK) is an evolutionarily conserved serine/threonine kinase whose activation elicits insulin-sensitizing
effects, making it an ideal therapeutic target for T2D. AMPK is an energy-sensing enzyme that is activated when cellular energy levels are low, and it ...

The Locomotor Kinematics Of Asian And African Elephants: Changes With Speed And Size, John R. Hutchinson, Delf Schwerda, Daniel J. Famini, Robert H.I. Dale, Martin S. Fischer, Rodger Kram

Robert H. I. Dale

For centuries, elephant locomotion has been a contentious and confusing challenge for locomotion scientists to understand, not only because of technical difficulties but also because elephant locomotion is in some ways atypical of more familiar quadrupedal gaits. We analyzed the locomotor kinematics of over 2400 strides from 14 African and 48 Asian elephant individuals (body mass 116-4632 kg) freely moving over ground at a 17-fold range of speeds, from slow walking at 0.40 m s-1 to the fastest reliably recorded speed for elephants, 6.8 m s-1. These data reveal that African and Asian elephants have some subtle differences ...


Impact Shock Frequency Components And Attenuation In Rearfoot And Forefoot Running, Allison H. Gruber, Katherine A. Boyer, Timothy R. Derrick, Joseph Hamill May 2014

Impact Shock Frequency Components And Attenuation In Rearfoot And Forefoot Running, Allison H. Gruber, Katherine A. Boyer, Timothy R. Derrick, Joseph Hamill

Katherine A. Boyer

Background The forefoot running footfall pattern has been suggested to reduce the risk of developing running related overuse injuries due to a reduction of impact related variables compared with the rearfoot running footfall pattern. However, only time-domain impact variables have been compared between footfall patterns. The frequency content of the impact shock and the degree to which it is attenuated may be of greater importance for injury risk and prevention than time-domain variables. Therefore, the purpose of this study was to determine the differences in head and tibial acceleration signal power and shock attenuation between rearfoot and forefoot running. Methods ...

Effects Of Foot Position During Squatting On The Quadriceps Femoris: An Electromyographic Study, Nicholas Murray, Daniel Cipriani, Denise O'Rand, Rebecca Reed-Jones

Daniel Cipriani

International Journal of Exercise Science 6(2) : 114-125, 2013. Weightlifters have commonly believed that changing joint position can alter specific muscle activation. The magnitude of force produced by a muscle is highly dependent upon the length of the muscle. The purpose of this study was to determine the effect of foot positioning on muscle activation of the superficial quadriceps as measured by surface electromyography (sEMG) during a functional squatting movement in healthy adults. Twenty physically active asymptomatic adults (7 females and 13 males) were included in the study while four different foot positions (Neutral, Internally Rotated, Externally Rotated, and Staggered ...

The Reliability Of Three Isokinetic Knee-Extension Angle-Specific Torques, B. L. Arnold, D. H. Perrin, Evan V. Hellwig Feb 2014

The Reliability Of Three Isokinetic Knee-Extension Angle-Specific Torques, B. L. Arnold, D. H. Perrin, Evan V. Hellwig

Evan V. Hellwig, Ph.D.

To determine the reliability of concentric quadriceps muscle torque at 30°, 60°, and 75° of knee extension, 25 female university students were studied. Each subject was tested on the Kin-Com isokinetic dynamometer on 2 separate days, 7 days apart. The dynamometer's speed was set at 60°ls. Intraclass correlation coefficients for 30°, 60°, and 75° were 0.84 (p<.01), 0.87 (p<.01), and 0.83(p<.01), respectively. The standard errors of the measure were 5.92 N·m, 7.65 N·m, and 7.35 N·m, respectively. Based on the instrumentation and protocol used in this study, we believe angle-specific torques have good reliability. Because of the error size, clinicians using similar methodology to determine angle-specific torques should be cautious when comparing differences between angle-specific torques of less than 12 to 16 N·m.
