OBJECTIVE The aim of this study was to evaluate the occurrence of the well-known predisposing factors and signs and symptoms usually associated with either overreaching or overtraining syndrome in physical fitness centers in São Paulo City, Brazil. METHOD A questionnaire consisting of 13 question groups pertaining to either predisposing factors (1-7) or signs and symptoms (8-13) was given to ...

Background: Overtraining occurs when an optimization process is applied for too many steps, leading to a model describing noise in addition to the signal present in the data. This effect may affect typical approaches for species tree reconstruction that use maximum likelihood optimization procedures on a small sample of concatenated genes. In this context, overtraining may result in trees bette...

Resistance exercise can result in localized damage to muscle tissue. This damage may be observed in sarcolemma, basal lamina, as well as, in the contractile elements and the cytoskeleton. Usually the damage is accompanied by release of enzymes such as creatine kinase (CK) and lactate dehydrogenase, myoglobin and other proteins into the blood. Serum CK has been proposed as one of the best indire...

Endurance athletes alternate periods of intensive physical training with periods of rest and recovery to improve performance. An imbalance caused by overly intensive training and inadequate recovery leads to a breakdown in tissue reparative mechanisms and eventually to overuse injuries. Tendon overuse injury is degenerative rather than inflammatory. Tendinopathy is often slow to resolve and res...

Systematic physical activity increases physical fitness and exercise capacity that lead to the improvement of health status and athletic performance. Considerable effort is devoted to identifying new biomarkers capable of evaluating exercise performance capacity and progress in training, early detection of overtraining, and monitoring health-related adaptation changes. Recent advances in OMICS t...

The present study focused on the identification of the difference in expression of inflammation-related genes after intense exercise by oligonucleotide microarray methods. This may finally lead to an improved understanding of underlying cellular and molecular mechanism of the immunological alterations in response to exercises. The study group consisted of three healthy road cyclists. Peripheral...

A resistance training protocol of low intensity and short duration allows for increased training frequency and improved compliance. This study aimed to examine the short-term (response of growth hormone (GH) and testosterone after one exercise session) and long-term (change of fitness level and body fat percentage after the exercise period) effects of slow movement resistance training using the...

Exercise has several hemorheological effects that we previously proposed to classify as a triphasic phenomenon: acute effects (hyperviscosity mostly due to hemoconcentration but also to some alterations of erythrocyte properties); delayed effects (hyperhydration resulting in hemodilution and hypoviscosity), and a chronic situation which can be termed hemorheologic fitness. This presentation foc...

Biomarker discovery and validation is a critical aim of the medical and scientific community. Research into exercise and diet-related biomarkers aims to improve health, performance, and recovery in military personnel, athletes, and lay persons. Exercise physiology research has identified individual biomarkers for assessing health, performance, and recovery during exercise training. However, the...
