Tendinopathy is a widespread and disabling condition characterized by collagen fiber disruption and accumulation of a glycosaminoglycan-rich chondroid matrix. Recent clinical reports have illustrated the potential of mechanical loading (exercise) therapies to successfully treat chronic tendinopathies. We have developed a new murine tendinopathy model which requires a single injection of ...

It has previously been shown that low-frequency neuromuscular electrical stimulation (NMES) techniques can induce increases in energy expenditure similar to those associated with exercise. This study investigated the metabolic and cardiovascular effects of a 1 h session of lower limb NMES and compared cardiovascular response with that observed during walking ...

Purpose: Within supervised rehabilitation programs, Lent and Lopez (2002) proposed that clients and therapists develop a "tripartite" network of efficacy beliefs, comprising their confidence in their own ability, their confidence in the other person's ability, and their estimation of the other person's confidence in them. To date, researchers have yet ...

According to popular models of human time perception, variations in prospective timing are caused by two factors: the pulse rate of an internal pacemaker and the amount of attention directed to the passage of time. The results concerning the effect of attention on subjective timing have been conclusive, but the ...

Exercise for Health was a randomized, controlled trial designed to evaluate two modes of delivering (face-to-face [FtF] and over-the-telephone [Tel]) an 8-month translational exercise intervention, commencing 6-weeks post-breast cancer surgery (PS).

Studies on the effects of acute bouts of cardiovascular exercise on cognitive performances show contradictory findings due to methodological differences (e.g., exercise intensity, cognitive function assessed, participants' aerobic fitness level, etc.). The present study assessed the acute effect of exercise intensity on cognition while controlling for key methodological confounds. Thirty-seven ...

OBJECTIVES: The goal of this study was to compare the prognostic efficacy of the 6-minute walk (6MW) and cardiopulmonary exercise (CPX) tests in stable outpatients with chronic heart failure (HF). BACKGROUND: CPX and 6MW tests are commonly applied as prognostic gauges for systolic HF patients, but few direct comparisons have ...

BACKGROUND: Protein ingestion after a single bout of resistance-type exercise stimulates net muscle protein accretion during acute postexercise recovery. Consequently, it is generally accepted that protein supplementation is required to maximize the adaptive response of the skeletal muscle to prolonged resistance-type exercise training. However, there is much discrepancy in the ...

INTRODUCTION: Exercise not only benefits physical and cardiovascular function in older adults with multiple chronic conditions, but may also improve cognitive function. Peak heart rate (HR), a physiological indicator for maximal effort, is the most common and practical means of establishing and monitoring exercise intensity. In particular, in the absence ...

This study used near-infrared diffuse optical spectroscopies to noninvasively evaluate muscle blood flow, blood oxygenation and oxygen metabolism during leg fatiguing exercise ...

Abstract Historically, the approach of promoting exercise by emphasizing its effects on long-term health has predominated. Despite this tradition, there is no strong empirical support for such an approach. Recent work has argued that exercise suffers from a "branding problem" and efforts to promote exercise may be better served by ...

PURPOSE: While left ventricular (LV) adaptation to exercise training has been the focus of 'athlete's heart' research to-date, information regarding right ventricular (RV) adaptation is sparse, due to its complex structure and imaging technique limitations. This is the first prospective, longitudinal randomized study exploring the impact of endurance (E) versus ...

Overuse-induced injuries have been proposed as a predisposing factor for Achilles tendon (AT) ruptures. If tendons can be overloaded, their mechanical properties should change during exercise. Because there data are lacking on the effects of a single bout of long-lasting exercise on AT mechanical properties, the present study measured AT ...

Aging is a natural and complex physiological process influenced by many factors, some of which are modifiable. As the number of older individuals continues to increase, it is important to develop interventions that can be easily implemented and contribute to "successful aging". In addition to a healthy diet and psychosocial ...

BACKGROUND: Low-frequency heart rate variability (LF-HRV) at rest has already been successfully modeled as self-sustained oscillations in a nonlinear control loop, but these models fail to simulate LF-HRV decreases either during aerobic exercise or in heart failure patients. Following control engineering practices, we assume the existence of a biological excitation ...
