Prediction of central Augmentation Index in healthy adults.

Background: Central Augmentation Index (AIx) is a surrogate marker of large artery stiffness that may provide valuable insight to cardiovascular health. The aim of this study was to evaluate the relationship between AIx and components of physical fitness.

Methods: One hundred eighty-five healthy men and women (aged 20-79 years) underwent non-invasive assessment of arterial wave reflection to determine AIx, which was corrected to a heart rate of 75 beats per minute (AI×75).

Examination of overhead and single-leg squat kinematics and lower extremity injury in female collegiate athletes.

Background: Overhead squat (OHS) and single-leg squat (SLS) tests have been used as screening tools to identify injury risk in athletic populations. Yet, no study has examined the association between specific trunk and lower extremity (LE) kinematic measures acquired during OHS and SLS performance and LE injury incidence in female collegiate athletes. The purpose of this study was to examine the association between LE and trunk kinematics captured during OHS and SLS performance and LE injury in female collegiate athletes.

Rationale and Feasibility of Resistance Training in hEDS/HSD: A Narrative Review.

Hypermobile Ehlers-Danlos Syndrome (hEDS) and hypermobility spectrum disorder (HSD) are genetic conditions characterized by increased joint hypermobility, often in the presence of other signs or symptoms if syndromic. This hypermobility can result in significant pain and ultimately decreased participation in recreational or competitive activity. Rehabilitation of patients with hEDS/HSD is not well understood, particularly since presentation can be relatively heterogenous.

High-intensity functional exercise does not cause persistent elevations in augmentation index in young men and women.

Elevations in central augmentation index (AIx) are predictive of cardiovascular disease. The objective of this study was to examine AIx immediately and 24 h following an acute bout of high-intensity functional training (HIFT) in apparently healthy young adults. A second aim compared the exercise-induced AIx recovery response between men and women.

Yeast Beta-Glucan Supplementation Downregulates Markers of Systemic Inflammation after Heated Treadmill Exercise.

Aerobic exercise and thermal stress instigate robust challenges to the immune system. Various attempts to modify or supplement the diet have been proposed to bolster the immune system responses. The purpose of this study was to identify the impact of yeast beta-glucan () supplementation on exercise-induced muscle damage and inflammation.

Nutrient Status and perceptions of energy and macronutrient intake in a Group of Collegiate Female Lacrosse Athletes.

Effectiveness of Studying When Coupled with Exercise-Induced Arousal.

The basis of learning is knowledge of discrete information such as terms and definitions that can be developed through memorization. A strong knowledge base is something students strive to develop through self-directed study. Little research has investigated the role of simultaneous exercise and memorization on recall ability with a delay in recall of at least 24 hrs.

Multi-ingredient pre-workout supplements, safety implications, and performance outcomes: a brief review.

In recent years, a new class of dietary supplements called multi-ingredient pre-workout supplements (MIPS) has increased in popularity. These supplements are intended to be taken prior to exercise and typically contain a blend of ingredients such as caffeine, creatine, beta-alanine, amino acids, and nitric oxide agents, the combination of which may elicit a synergistic effect on acute exercise performance and subsequent training adaptations compared to single ingredients alone. Therefore, the purpose of this article was to review the theoretical rationale and available scientific evidence assessing the potential ergogenic value of acute and chronic ingestion of MIPS, to address potential safety concerns surrounding MIPS supplementation, and to highlight potential areas for future research.

Lack of joint hypermobility increases the risk of surgery in adolescent idiopathic scoliosis.

Generalized joint hypermobility (GJH) is a risk factor for developing adolescent idiopathic scoliosis (AIS); however, it is not known whether joint hypermobility influences the risk of progression to surgery. Beighton joint hypermobility scores were assessed in 570 female AIS patients. Multivariate analysis was carried out to determine whether Beighton hypermobility scores were predictors of surgical intervention.

Scoliosis severity does not impact the risk of scoliosis in family members.

Does scoliosis severity increase scoliosis risk or severity in relatives? In a cohort of 1257 severe idiopathic scoliosis patients, the percentage with at least one affected relative was compared across the categories of patient sex, major curve severity (Cobb angle), and treatment method. In total, 138 (11%) of 1257 patients had at least one affected first-degree relative and 59 (5%) had at least one affected second-degree relative. As expected, males were more likely to have affected first-degree relatives than females (18 vs.
