Successful training not only must involve overload but also avoid the combination of excessive plus inadequate recovery. Athletes can experience short-term performance decrement without severe psychological or lasting other negative symptoms. This functional overreaching will eventually lead to an improvement in after When athletes do sufficiently respect balance between and recovery, nonfunctional (NFOR) occur.

Athletes participating in elite sports are exposed to high training loads and increasingly saturated competition calendars. Emerging evidence indicates that poor load management is a major risk factor for injury. The International Olympic Committee convened an expert group review the scientific relationship of (defined broadly include rapid changes load, calendar congestion, psychological travel) health outcomes sport. We summarise results linking injury athletes, provide coaches support...
The modern-day athlete participating in elite sports is exposed to high training loads and increasingly saturated competition calendar. Emerging evidence indicates that inappropriate load management a significant risk factor for acute illness the overtraining syndrome. IOC convened an expert group review scientific relationship of load—including rapid changes load, calendar congestion, psychological travel—and health outcomes sport.

Purpose The aim this study was to develop a test protocol determine at which oxidation rate is (Fatmax). Method Eighteen moderately trained cyclists performed graded exhaustion, with 5-min stages 35-W increments (GE35/5). In addition, four six continuous prolonged tests (CE) constant work rates, corresponding rates...
Abstract Successful training must involve overload but also avoid the combination of excessive plus inadequate recovery. Athletes can experience short term performance decrement, without severe psychological, or lasting other negative symptoms. This Functional Overreaching (FOR) will eventually lead to an improvement in after When athletes do not sufficiently respect balance between and recovery, Non‐Functional (NFOR) occur. The distinction NFOR Overtraining Syndrome (OTS) is very difficult...
Abstract Successful training must involve overload, but also avoid the combination of excessive overload plus inadequate recovery. Athletes can experience short‐term performance decrement, without severe psychological, or lasting other negative symptoms.

The relationship between physiological and psychological stress immune function is widely recognized; however, there little evidence to confirm a direct link depressed incidence of illness in athletes. Purpose: To examine the salivary immunoglobulin A (s-IgA) upper respiratory infections (URI) cohort professional athletes over prolonged period. Methods: Thirty-eight elite America's Cup yacht racing were studied 50 wk training. Resting, unstimulated saliva samples collected weekly (38 h after...
Football is a global game which constantly evolving, showing substantial increases in physical and technical demands. Nutrition plays valuable integrated role optimising performance of elite players during training match-play, maintaining their overall health throughout the season. An evidence-based approach to nutrition emphasising, 'food first' philosophy (ie, food over supplements), fundamental ensure effective player support. This requires relevant scientific evidence be applied...
To study the cumulative effects of exercise stress and subsequent recovery on performance changes fatigue indicators, training eight endurance cyclists was systematically controlled monitored for a 6-wk period. Subjects completed 2 wk normal (N), intensified (ITP), training. A significant decline in maximal power output (N = 338 +/- 17 W, ITP 319 W) increase time to complete simulated trial 59.4 1.9 min, 65.3 2.6 min) occurred after conjunction with 29% global mood disturbance. The...
The purpose of this study was to examine the effects a probiotic supplement during 4 mo winter training in men and women engaged endurance-based physical activities on incidence upper respiratory-tract infections (URTIs) immune markers. Eighty-four highly active individuals were randomized ( n = 42) or placebo groups and, under double-blind procedures, received (PRO: Lactobacillus casei Shirota [LcS]) (PLA) daily for 16 wk. Resting blood saliva samples collected at baseline after 8 Weekly...
Abstract Lipid peroxidation initiated by free radical reactions is associated with tissue necrosis in a variety of conditions. We have measured serum lipid peroxide concentrations (as total thiobarbituric acid‐reactive substances, TBARS) and creatine kinase (CK), lactate dehydrogenase (LDH), aspartate aminotransferase (AST) activities subjective muscle soreness 16 men before after 45‐minute downhill treadmill run. TBARS enzyme were increased exercise, peak values observed at 6 hours (TBARS,...
The aim of the present study was to compare effects exercise at 80 %VO2max (resulting in fatigue within 1 h) with more prolonged a lower work rate (55 % VO2max for up 3 on blood neutrophil function and plasma concentrations Cortisol, glutamine glucose. Eighteen: healthy male subjects (mean±SD age 22.5±3.7yrs, 60.1±6.6 ml·kg-1·min-1) cycled an electrically braked ergometer (37±19 min). On another occaision, separated by least one week, performed excercise same 55 h or fatigiue, whichever...
In the present study, we assessed effects of exercise intensity on salivary immunoglobulin A (s-IgA) and lysozyme (s-Lys) examined how these responses were associated with markers adrenal activation. Using a randomized design, 10 healthy active men participated in three experimental cycling trials: 50% maximal oxygen uptake (VO2max), 75%VO2max, an incremental test to exhaustion. The durations trials same as for preliminary exhaustion (22.3 min, sx = 0.8). Timed, unstimulated saliva samples...
Eleven mammalian toll-like receptors (TLRs 1-11) have been identified to date and are known play a crucial role in the regulation of immune responses; however, factors that regulate TLR expression function vivo poorly understood. Therefore, present study, we investigated physiological humans. To examine influence diurnal rhythmicity on function, peripheral venous blood samples were collected from healthy volunteers (n = 8) at time points coinciding with peak nadir endogenous circulating...
