The current diagnosis of overreaching and overtraining is based on exclusion. In the present paper, four possible confirmative tools have been examined in three female speed skaters between 16 and 19 years old. A nonfunctional overreached (NFO) athlete, an athlete who was recovering from NFO and a healthy athlete were examined. The NFO athlete showed high stress and low regeneration levels at the Recovery Stress Questionnaire for Athletes. The recovering athlete showed a more favorable profile, although she still showed higher stress and lower recovery than the control athlete. On the Profile of Mood States, the NFO athlete showed an unfavorable profile. The control athlete showed the typical iceberg profile. The recovering athlete showed a profile similar to sedentary individuals. Results on a reaction time task showed decreased performance under pressure for the NFO but not for the control and the recovering athlete. Hormonal reactions to two maximal exercise bouts also differed between the three subjects with an overreaction after the second exercise bout of the NFO athlete as the most remarkable finding. The Recovery Stress Questionnaire for Athletes, reaction times and hormonal reactions to exercise showed to be possible tools that can be used in the diagnostic procedure.

Introduction: Special Operations Forces (SOF) Operators (SOs) are exposed to high levels of physiological and cognitive stressors early in their career, starting with the rigors of training, combined with years of recurring deployments. Over time, these stressors may degrade SOs' performance, health, and recovery.
Objectives: (1) To evaluate sources identifying and describing physiological and psychological stressors affecting performance, health, and recovery in SOs, and (2) to explore interventions and phenomena of interest, such as the biological mechanisms of overtraining syndrome (OTS).
The aim was to study the effects of non-functional overreaching and overtraining on responses of biomarkers of the skeletal muscle cell (CK-NAC) and cardiomyocyte injury (cTnI and CK-MB) and their use in monitoring OTS. In 43 athletes with non-functional overreaching (NFO)/overtraining syndrome (OTS) and 40 athletes without NFO/OTS -control athletes (CA) off-season measurements of creatine kinaze (CK-NAC and CK-MB) were performed, followed by peak-season evaluation of the dynamic of CK-NAC, CK-MB and cardiac troponin I (cTnI) changes. CK and cTnI levels were obtained 24 hrs before the strenuous exercise appropriate to the sport-specific peak-season intensity, immediately after completion of the work-load, after 6, 48, and 72hrs.

Introduction: This study aimed to simplify and optimize the distinction between nonfunctional overreaching (NFO) and overtraining syndrome (OTS) by developing a multivariate approach (discriminant analysis [DA]) including hormonal and psychological changes measured during the Training Optimization (TOP) test.
Methods: Sensitivity of previously defined cutoff values for hypothalamic-pituitary-adrenal axis hormonal changes were recalculated on a larger database (n = 100). Discriminant analysis including hormonal and psychological variables measured during the TOP test was used to discriminate between NFO and OTS and predict the diagnosis of new cases.

Aim of the study was to examine the relationship between oxidative stress and overtraining syndrome in athletes by evaluation in serum oxidative and antioxidant status. In 43 athletes with non-functional overreaching (NFO)/overtraining syndrome(OTS) and 40 athletes without NFO/OTS -control athletes (CA), diacron-reactive oxygen metabolites (d-ROMs) and biological antioxidant potential (BAP) in serum, as well as ratio of d-ROMs and BAP test measurements - marker of oxidative stress, were assessed. Baseline data collection performed in both groups of athletes - with NFO/OTS and CA, followed by data collection in athletes with NFO/OTS after 28 days of rest.

Background: Elite water polo athletes undergo heavy training programs throughout the year, but especially to prepare major competitions, such as the Olympic Games (OG). Optimal athletic performance is a result of many factors, including proper management of the intensity and volume of training, nutrition and recovery between training sessions. When training is excessive in relation to recovery may occur nonfunctional overreaching (NFO).
