Exercise Performance

In recent years, research investigating the dose-response to sprint interval training (SIT) has provided evidence that the number and duration of repetitions in a SIT session can be reduced whilst preserving the beneficial health-related adaptations. Together this research has led to the development of protocols involving minimal doses of SIT: regularly performing just two or three 20-30-s all-out sprints in a 10-min training session has been shown to elicit beneficial metabolic and cardiovascular adaptations...

INTRODUCTION: Patients with primary mitral regurgitation (MR) usually remain asymptomatic for a long time due to compensatory mechanisms and an adequate treatment could be delayed. Stress echocardiography and speckle-tracking analysis could help to evaluate impaired left atrium (LA) function before the manifestation of clinically significant myocardial changes in asymptomatic patients with primary MR and preserved left ventricular (LV) ejection fraction (EF). METHODS: This study prospectively enrolled 91 patients with preserved LV EF (≥60%) at rest, of which 60 patients had moderate-to-severe MR and 31 were healthy controls...

BACKGROUND: The COVID-19 pandemic has significantly reduced physical activity (PA) levels and increased sedentary behavior (SB), which can lead to worsening physical fitness (PF). Children and adolescents may benefit from mobile health (mHealth) apps to increase PA and improve PF. However, the effectiveness of mHealth app-based interventions and potential moderators in this population are not yet fully understood. OBJECTIVE: This study aims to review and analyze the effectiveness of mHealth app-based interventions in promoting PA and improving PF and identify potential moderators of the efficacy of mHealth app-based interventions in children and adolescents...

Limited objective data exist on the comparison of post-endoscopic retrograde cholangiopancreatography (ERCP) complications in patients with cirrhosis based on the severity of the disease. We evaluated the effectiveness of the Child-Turcotte-Pugh (CTP) score system in anticipating the risk of post-ERCP complications in patients with cirrhosis. The PubMed, Scopus, Embase, and Cochrane databases were searched from inception through September 2022 to identify studies comparing post-ERCP complications in patients with cirrhosis based on CTP score...

OBJECTIVES: As symptoms emerge and worsen in people living with dementia, their spouses can benefit from behavioral interventions to support their adjustment as a care partner. The Wish Outcome Obstacle Plan (WOOP) intervention improves the well-being of spouses of people living with dementia early in the disease course, but intervention mechanisms and opportunities for improvement are unclear. The present study gave voice to spouses who participated in a trial of WOOP, describing how WOOP was incorporated into their lives and how it could be improved for future implementation...

INTRODUCTION: The purpose of our report was to use a Random Forest classification approach to predict the association between transcutaneous electrical nerve stimulation (TENS) and walking kinematics at the stride level when middle-aged and older adults performed the 6-min test of walking endurance. METHODS: Data from 41 participants (aged 64.6 ± 9.7 years) acquired in two previously published studies were analyzed with a Random Forest algorithm that focused on upper and lower limb, lumbar, and trunk kinematics...

PURPOSE: The aim was to quantify jump performance in children with cerebral palsy (CP) and determine if the expected deficit is related to their lower-body-joint kinetics and kinematics. METHODS: Twenty-four ambulatory (n = 17 level I and 7 level II in the Gross Motor Function Classification System) children with spastic CP (n = 13 unilateral and 11 bilateral) and 24 age-, sex-, and race-matched typically developing controls were studied. Jump height and peak power and range of motion at the hip, knee, and ankle of the more affected limb in children with CP and the nondominant limb in controls were assessed during a countermovement jump using three-dimensional motion capture and a force platform...

BACKGROUND: Although moderate endurance exercise has been reported to improve cardiovascular health, its effects on cardiac structure and function are not fully characterized, especially with respect to sexual dimorphism. We aimed to assess the effects of moderate endurance exercise on cardiac physiology in male versus female mice. METHODS AND RESULTS: C57BL/6J mice of both sexes were run on a treadmill for 6 weeks. ECG and echocardiography were performed every 2 weeks...

BACKGROUND: Major abdominal surgery is associated with a high rate of post-operative complications with increased risk of adverse surgical outcomes due to the presence of frailty. This study aims to evaluate the effectiveness of the multimodal Recovery of Surgery in the Elderly (ROSE) prehabilitation program with supervised exercise in mitigating postoperative functional decline when compared to standard care. METHOD: The ROSE program enrolled ambulant patients who were 65 years and above, had a Clinical Frailty Scale score of 4 or more and were planned for major abdominal surgery...

Objective: Traditionally, perfectionism has been regarded as a commendable trait in the realm of sports and exercise. However, recent research has uncovered a paradoxical aspect of perfectionism in these domains. This umbrella review seeks to offer a comprehensive overview of the intricate role that perfectionism plays in sport and exercise performance. Method : As an umbrella review, we systematically explored three widely used scientific databases-PubMed, Scopus, and ISI-to identify relevant systematic reviewes and meta-analyses investigating the relationship between perfectionism and sports performance...

Viral encephalitis poses a significant threat to public health, particularly affecting children and the elderly. We present a case of a 1.5-year-old child with viral encephalitis, characterized by sudden convulsions following a bout of cold and fever. Comprehensive physiotherapy rehabilitation was initiated, focusing on improving mobility, strength, and functional abilities. The interventions included caregiver education, range of motion exercises, strengthening exercises, mobility training, and task-oriented activities...

INTRODUCTION: Groin injuries represent a considerable problem in football. Although the Adductor Strengthening Programme reduced groin injury risk, players can still experience groin symptoms throughout the season. This study aimed to determine whether preseason Copenhagen Hip and Groin Outcome Score (HAGOS) and a history of previous injury can identify individuals at risk of having a longer duration of groin problems the subsequent season, using an 'any physical complaint' definition of injury...

The aim of this study was to analyse the reasons health professionals refer to sport and exercise physicians (SEPs) and to define what service gap the specialty fills. This was a qualitative study design using thematic analysis. Online focus group interviews consisting of 4-6 participants in each group were conducted separately with physiotherapists, emergency clinicians, general practitioners and orthopaedic surgeons practising in New Zealand. Thematic analysis of the focus group interviews was then used for the identification of common themes around referral tendencies towards SEPs...

BACKGROUND/OBJECTIVE: Constraint-induced movement therapy (CIMT), a therapy that encourages the use of the affected upper limb through intensive functional tasks, effectively promotes upper limb function in patients with chronic stroke. This study determined the effectiveness of CIMT using telerehabilitation compared with traditional CIMT in improving mild to moderate upper limb motor function in adult patients with chronic stroke. METHODS: Eligible studies were identified by searching electronic databases and scanning the reference lists of articles...
