Development and Validation of the High Performance Volleyball Self-Efficacy Scale.

In this study, we aimed to develop and psychometrically examine a self-efficacy scale for high-performance volleyball athletes. A literature review and interviews with 16 experts led to construction of item content. A preliminary version of the scale was then administered to 24 high-performing adult athletes, followed by administration of the scale to 300 Brazilian high-performing volleyball athletes ( age = 24.

Effect of mental fatigue on performance, perceptual and physiological responses in orienteering athletes.

Background: Mental fatigue seems to impair the athletes' performance; however, in sports with high cognitive demand, such as orienteering, this negative effect could be attenuated during the race. Therefore, this study investigated mental fatigue effect on performance, perceptual, and physiological responses in orienteers.

Methods: Fifteen male orienteers (30±8 years) participated in the study.

Torque and Muscle Activation Impairment Along With Insulin Resistance Are Associated With Falls in Women With Fibromyalgia.

Góes, SM, Stefanello, JMF, Homann, D, Lodovico, A, Hubley-Kozey, CL, and Rodacki, ALF. Torque and muscle activation impairment along with insulin resistance are associated with falls in women with fibromyalgia. J Strength Cond Res 30(11): 3155-3164, 2016-Fibromyalgia (FM) is a chronic pain condition associated with reduced muscle strength, which can lead to functional incapacity and higher risk of falls.

Ankle dorsiflexion may play an important role in falls in women with fibromyalgia.

Background: Fibromyalgia is a chronic pain condition, which involves reduced range of motion. This leads to gait changes and high incidence of falls. The understanding of the gait patterns in subjects with fibromyalgia and their relationship with falls may be useful when designing intervention programs.

[Gait characteristics of women with fibromyalgia: a premature aging pattern].

Background: Fibromyalgia is a condition which involves chronic pain. Middle-aged individuals with fibromyalgia seem to exhibit changes in gait pattern, which may prematurely expose them to a gait pattern which resembles that found in the elderly population.

Objective: To determine the 3D spatial (linear and angular) gait parameters of middle-aged women with fibromyalgia and compare to elderly women without this condition.

Hyperleptinemia independent of body adiposity in women with fibromyalgia.

The prevalence of overweight and obesity in patients with fibromyalgia is high, which makes these patients more likely to trigger metabolic changes. It is also uncertain whether the clinical manifestations of fibromyalgia alter the metabolism in these patients. This study investigates the influence of adiposity indicators and presence of fibromyalgia on leptin and acylated ghrelin levels, which are hormones responsible for controlling energy homeostasis.

Physical activity level and physical performance in the 6-minute walk test in women with fibromyalgia.

Introduction: Fibromyalgia (FM) is a chronic pain condition that causes impaired functional capacity, possibly through the adoption of sedentary behaviour. However, little is known regarding physical activity level and its relationship with physical performance in women with FM.

Objectives: To compare physical activity level, assessed using the International Physical Activity Questionnaire (IPAQ), and physical performance, measured using the six-minute walk test (6MWT), in women with and without FM, and to examine the possible relationships between physical activity level and physical performance in both groups.

Atherosclerosis subclinical and inflammatory markers in obese and nonobese children and adolescents.

We conducted a systematic review of intima-media thickness(IMT) and inflammatory markers, compared IMT and identified by meta-analysis related to EMI and inflammatory variables in obese and non-obese children and adolescents. We searched for articles in databases Pubmed, Bireme and Science Direct, during years 2000 to 2010, with the following key words in English: "obesity", "adolescents", "atherosclerosis" and "child ", They were used in two combinations: obesity + adolescents + atherosclerosis + child + obesity and atherosclerosis. We used meta-analysis to compare IMT between obese and non-obese patients.

Use of multimodal imagery with precompetitive anxiety and stress of elite tennis players.

The effect of multimodal imagery on anxiety and perceived stress was investigated in 46 male tennis players (16 to 18 yr.; M = 17.0, SD = 0.

Stress perception and depressive symptoms: functionality and impact on the quality of life of women with fibromyalgia.

Introduction: Depression is one of the most frequent psychiatric comorbidities in patients with fibromyalgia (FM), and chronic stress might be one of the triggering events of the characteristic FM symptoms.

Objectives: To compare depressive symptoms and stress perception between women with and without FM, in addition to investigate the relationship between those characteristics and the functionality and the impact on the quality of life of those patients.

Methods: The study included 20 women with FM (FM group) and 20 healthy women (control group).

Functional capacity, muscle strength and falls in women with fibromyalgia.

Background: Patients with fibromyalgia have difficulty with activities of daily living, they exhibit reduced muscle strength and high incidence of reported falls. The objective of this study was to evaluate the functional performance and lower limb muscle strength in women with fibromyalgia and determine the relationship between muscle strength and falls.

Methods: Sixteen females with fibromyalgia and 16 healthy women participated in the study.

Impaired functional capacity and exacerbation of pain and exertion during the 6-minute walk test in women with fibromyalgia.

Background: Fibromyalgia has been association with physical performance limitations. Additionally, activities of daily living have been reported to be directly associated with the exacerbation of pain and perceived exertion in this patient population.

Objectives: To compare the performance of a 6-minute walk (6MWT) test in patients with fibromyalgia and controls and to evaluate the relationship between test performance and quality of life, limitations of activities of daily living and physical activity level.
