Age- and sex-specific normative references and performance zones for core muscular endurance in adolescents aged 12-16 years: a cross-sectional study.

Sampling matters: the interplay of physiological parameters and performance over 1, 2 and 3 km in well-trained male endurance runners and sprinters.

Geographies of Resistance

Until very recently questions of resistance seemed straightforward, addressed in terms of an analysis of power. This book demonstrates how new, radical geographies of resistance emerge, develop and operate. Radical cultural politics, exemp...

Association of mitochondrial DNA polymorphisms and/or haplogroups with elite Japanese athlete status

A number of familial and twin studies have assessed the relative contribution of genetic and environmental factors to physical performance or its-related traits and have estimated that there is a significant genetic component to their pheno...

Study on Flight Performance of Propeller-Driven UAV

The engine performance test at altitudes of 0-7000 m was carried out on the high-performance test bench of the Unmanned Aerial Vehicle (UAV) piston engine. The flight performance of UAV was studied, including propeller thrust characteristic...

Effects of Interval Training Under Hypoxia on Hematological Parameters, Hemodynamic Function, and Endurance Exercise Performance in Amateur Female Runners in Korea

Interval training under hypoxia (IHT) is commonly used to enhance endurance exercise performance. However, previous studies examining hematologic changes related to the immune system that affect health and conditioning are lacking. This stu...

Inspiratory pressure waveform influences time to failure, respiratory muscle fatigue, and metabolism during resistive breathing

Abstract Increased ventilatory work beyond working capacity of the respiratory muscles can induce fatigue, resulting in limited respiratory muscle endurance (Tlim). Previous resistive breathing investigations all applied square wave inspira...

Flavanol-Rich Cocoa Supplementation Inhibits Mitochondrial Biogenesis Triggered by Exercise

The potential role of cocoa supplementation in an exercise context remains unclear. We describe the effects of flavanol-rich cocoa supplementation during training on exercise performance and mitochondrial biogenesis. Forty-two male enduranc...

Psychometric facets of Antifragility: Tolerance of Ambiguity, Hardiness, and Growth

This paper considers the issues, which are concerned with a new concept of antifragility. Quite recently, considerable attention has been paid to the concept of antifragility. Antifragility gains a special importance in studying psychologic...

Physical Activity and Public Health

In 1995 the American College of Sports Medicine and the Centers for Disease Control and Prevention published national guidelines on Physical Activity and Public Health.The Committee on Exercise and Cardiac Rehabilitation of the American Hea...

High‐Sensitivity Cardiac Troponin I and T Response Following Strenuous Activity is Attenuated by Smokeless Tobacco: NEEDED (North Sea Race Endurance Exercise Study) 2014

Background Use of snus, a smokeless tobacco product, is increasing in Scandinavia. Strenuous physical activity is associated with an acute increase in high‐sensitivity cardiac troponin (swhs‐cTn) concentrations. Current smoking is associate...

Variations in lower‑limb body composition asymmetry and leg length discrepancy by sex and training level, and their association with performance in recreational endurance runners: a cross‑sectional study.

An adaptive energy management and control framework for long-endurance UAV missions in dynamic environments: A reproducible simulation study.
