Abstract Purpose To compare biomechanical aspects of a novel “running” diagonal stride (DSRUN) with conventional diagonal stride (DSCONV) skiing techniques performed at high speed. Methods Ten elite Italian male junior cross-country skiers skied on a treadmill at 10 km/h and 10° incline utilizing both variants of the diagonal stride technique. The 3-dimensional kinematics of the body, poles, and roller skis; the force exerted through the poles and foot plantar surfaces; and the angular motion of...

Abstract Background The objective of this review was to synthesize previous findings on the test-retest reliability of the 30–15 Intermittent Fitness Test (IFT). Methods The literature searches were performed in eight databases. Studies that examined the test-retest reliability of the 30–15 IFT and presented the intraclass correlation coefficient (ICC) and/or coefficient of variation (CV) for maximal velocity and/or peak heart rate were included. The Consensus-based standards for the selection o...

Acute and chronic respiratory illnesses cause widespread morbidity and mortality, and this class of illness now includes the novel coronavirus severe acute respiratory syndrome (SARS-CoV-2) that is causing Coronavirus Disease 2019 (COVID-19). The world is experiencing a major demographic shift towards an older, obese, and physically inactive populace. Risk factor assessments based on pandemic data indicate that those at higher risk for severe illness from COVID-19 include older males, and people...
Abstract The first report demonstrating that prolonged endurance exercise promotes oxidative stress in humans was published more than four decades ago. Since this discovery, many ensuing investigations have corroborated the fact that muscular exercise increases the production of reactive oxygen species (ROS) and results in oxidative stress in numerous tissues including blood and skeletal muscles. Although several tissues may contribute to exercise-induced ROS production, it is predicted that mus...

Abstract Background Understanding factors influencing adolescents’ sport/exercise participation (S/EP) is vital to developing effective interventions, but currently evidence from less developed countries is limited. The purpose of this study was to examine correlates of S/EP across individual, interpersonal, and environmental levels in a nationally representative sample of Thai adolescents. Methods Data from 4617 Thai adolescents aged 14–17 years old were obtained from recruited schools across T...
Abstract Background Professional health organizations are not currently recommending Tai Ji Quana longside aerobic exercise to treat hypertension. We aimed to examine the efficacy of Tai Ji Quan as antihypertensive lifestyle therapy. Methods Tai Ji Quan interventions published in English and Chinese were included when they involved healthy adults, reported pre-and post-intervention blood pressure (BP), and had a non-exercise/non-diet control group. We systematically searched 11 electronic databa...
