Abstract: Background Strategies that impede blood flow could potentiate the effects of a warm-up due to their effects on the endothelial and metabolic functions. This study investigated whether performing a warm-up combined with blood-flow restriction (WFR) induces ergogenic changes in blood volume, muscle oxygenation, and RSA. Methods In a pair-matched, single-blind, pre-post parallel group design, 15 American football players completed...

Anche se è noto che l’esercizio fisico è salutare, molte persone trovano difficoltà nel mantenere un programma di esercizi per lunghi periodi, e questo vale ancora di più per le persone con una malattia cronica come il morbo di Parkinson, dove i limiti fisici e mentali possono rappresentare dei seri ostacoli. In uno studio finanziato da un’organizzazione olandese per la ricerca e lo sviluppo della salute, è stata provata una...

Introduction: Vitamin D and the antioxidant quercetin, are promising agents for improving physical performance because of their possible beneficial effects on muscular strength and cardiorespiratory fitness. Purpose: The purpose of this study was to determine the effects of increased intakes of vitamin D, quercetin, and their combination on antioxidant status, the steroid hormone regulators of muscle function, and measures of physical...

Abstract Background Overtraining syndrome (OTS), functional (FOR) and non-functional overreaching (NFOR) are conditions diagnosed in athletes with decreased performance and fatigue, triggered by metabolic, immune, hormonal and other dysfunctions and resulted from an imbalance between training stress and proper recovery. Despite previous descriptions, there is a lack of a review that discloses all hormonal findings in OTS/FOR/NFOR. The aim...

Abstract  We studied changes in blood markers of 18 nonprofessional, middle-aged runners of a 2-day, 130 km ultramarathon. Blood was sampled at baseline, after the goals on the first and second day, and at three time points (1, 3, and 5/6 days) after the race. Blood indices showed three patterns. First pattern indices showed essentially no changes after the two goals and after the race, including red blood cell indices, gamma-glutamyl...

Una nuova ricerca fornisce la prima spiegazione molecolare del perchè le persone aumentano di peso a causa di stress cronico, ritmi circadiani interrotti e trattamento con farmaci glucocorticoidi: secondo uno studio dei ricercatori della Stanford University School of Medicine, tutto sembra essere collegato al timing degli abbassamenti e innalzamenti di una classe di ormoni denominati glucocorticoidi, prevalentemente l’ormone dello...
