Peripheral physiological adaptations to exercise have been the subject of several studies. To adjust to the disturbance in resting homeostasis induced by the exercise stimulus, a number of regulatory systems are called upon to return the body to a new level of homeostasis. In contrast with our knowledge about the peripheral adaptations to exercise, studies relating exercise to brain neurotransm...

Thirteen standardbred horses were trained as follows: phase 1 (endurance training, 7 wk), phase 2 (high-intensity training, 9 wk), phase 3 (overload training, 18 wk), and phase 4 (detraining, 12 wk). In phase 3, the horses were divided into two groups: overload training (OLT) and control (C). The OLT group exercised at greater intensities, frequencies, and durations than group C. Overtraining o...

  Objective(s): The effect of prolonged overtraining on cytokine kinetics was compared with moderate exercise in the present study.   Materials and Methods: Male Wistar rats were randomly divided into control sedentary (C), moderate trained (MT), (V=20 m/min, 30 min/day for 6 days a week, 8 weeks), overtrained (OT) (V=25 m/min, 60min/day for 6 days a week, 11 weeks) and recovered overtrai...

Progression in resistance training is a dynamic process that requires an exercise prescription process, evaluation of training progress, and careful development of target goals. The process starts with the determination of individual needs and training goals. This involves decisions regarding questions as to what muscles must be trained, injury prevention sites, metabolic demands of target trai...

This paper will discuss the phenomenon that, despite continuous or increased training, performance of an athlete is stagnant or even decreases without any obvious reason such as illness or injury. There is still no uniform term to describe this phenomenon. Part 1 of this review paper will give an overview of the differently used terms and definitions in this connection. Independent of whether m...

Heart rate variability (HRV) is the present oscillation of the heart rate. The interest in HRV as a parameter of the parasympathetic and sympathetic influence of the autonomic nervous system on the heart has increased in the last few decades (Kaikkonen et al., 2007). It is known that its influence changes under different conditions such as rest, exercise or mental stress and different body post...
