INTRODUCTION: Evidence from civilian athletes raises the question of whether reproductive dysfunction may be seen in female soldiers as a result of military training. Such reproductive dysfunction consists of impaired ovulation with or without long-term subfertility. METHODS: A critical review of pertinent evidence following an extensive literature search. RESULTS: The evidence points towards reduced energy availability as the most likely explanation for exercise-induced reproductive dysfunction...

Many risk factors for injury are presented in the literature, few of those are however consistent and the majority is associated with adult and not adolescent elite athletes. The aim was to identify risk factors for injury in adolescent elite athletes, by applying a biopsychosocial approach. A total of 496 adolescent elite athletes (age range 15-19), participating in 16 different sports, were monitored repeatedly over 52 weeks using a validated questionnaire about injuries, training exposure, sleep, stress, nutrition and competence-based self-esteem...

Dental problems among athletes have been cautioned due to negative impacts not only on their oral health but also on athletic performance. Acquirement of appropriate oral health behavior mainly composed of toothbrushing in childhood can be one of the most important strategies for advancing children's athletic possibilities. Although habits of screen viewing, including game playing, and TV viewing have direct impacts on children's health and behavioral development, little is known about the association between these habits and toothbrushing frequency...

BACKGROUND: Symptoms related to concussion are generally found to be non-specific in nature as they are also reported by non-concussed individuals. What is currently not known is whether the symptoms vary over time, and whether they are also influenced by a multitude of factors. OBJECTIVE: To investigate the potential influence of psychological, lifestyle, and situational factors on the change in postconcussion-like symptoms reported over seven consecutive days in a cohort of normal individuals...

Sleep is often regarded as the single best recovery strategy available to an athlete, yet little is known about the quality and quantity of sleep in athletes during multi-day competitions. The present study objectively evaluated sleep characteristics of athletes during a national netball tournament. Using wrist actigraphy monitors and sleep diaries 42 netballers from four state teams were monitored for the duration of a tournament (6 days) and 12 days prior in home environments. Significant differences were found between teams based on final competition standings, suggesting enhanced sleep characteristics in athlete's whose team finished higher in the tournament standings...

INTRODUCTION: IL-6 has been ascribed both positive and negative roles in the context of exercise and training. The dichotomous nature of IL-6 signalling appears to be determined by the respective concentration of its receptors (both membrane-bound (IL-6R) and soluble (sIL-6R) forms). The purpose of the present study was to investigate the response of sIL-6R to long-term training, and to investigate the relationship between sIL-6R, self-reported measures of wellbeing, and upper respiratory illness symptoms (URS) in highly-trained endurance athletes...

The notion that prolonged, intense exercise causes an 'open window' of immunodepression during recovery after exercise is well accepted. Repeated exercise bouts or intensified training without sufficient recovery may increase the risk of illness. However, except for salivary IgA, clear and consistent markers of this immunodepression remain elusive. Exercise increases circulating neutrophil and monocyte counts, and reduces circulating lymphocyte count during recovery. This lymphopenia results from preferential egress of lymphocyte subtypes with potent effector functions (e...

The influence of the chronotype on the sleep quality in male collegiate soccer players in response to acute high intensity interval training (HIIT) performed at two different times of day was evaluated. The sleep quality was poorer in the morning-type than in the evening-type players after the evening HIIT session, whereas no significant changes in the sleep quality of the two chronotypes after the morning HIIT session was observed. The results suggest that an athlete's chronotype should be taken into account when scheduling training sessions and to promote faster recovery processes...
