Background: Heart rate variability (HRV) as a measure of the cardiac autonomic nervous system activity (CANA) has the potential to tailor endurance training and may contribute to the prevention of overtraining. We aimed to investigate whether there are sex differences and sex-specific reactions of the CANA to different training periods (TPs) in Swiss elite runners. Methods: Two HRV measurements (each 5 minutes supine and 5 minutes standing) per athlete were performed, the first during preparation period (PP) and the second during competition period (CP).

Supplement use in able-bodied athletes during major championships was reported to be around 80 to 90%. In contrast, the prevalence of supplement use in Paralympic athletes according to surveys from 2004 and 2012 was lower with around 40 to 58%. This study aimed to investigate the supplement use in Swiss wheelchair athletes. All Swiss wheelchair athletes were asked to complete a retrospective survey on supplement use during training and competition.

To counter progressive dehydration and thirst, athletes drink during exercise. However, despite decades of scientific research, there is still no conclusive answer regarding how much we should drink to optimize performance. The goal of this review article is to analyze the arguments underpinning contrasting perspectives and to critically analyze the available evidence. It seems that the respective argumentations of contrasting viewpoints are based on a different selective fraction of the available evidence.

The general recommendation for daily sodium consumption is about 6 g/d, as a higher intake was associated with an increased risk for cardiovascular mortality in individuals already suffering from hypertension. However, this recommendation is not necessarily valid for athletes as they often experience high sweat and sodium losses during exercise.

The importance of the carbohydrates for an intense exercise performance is known since at least the 1920s. Many research findings have since then led to development of generic recommendations for the carbohydrate intake before, during and after the exercise. The past years have witnessed, however, a growing understanding that the specific recommendations need to be defined in accordance to the short but also longer-term goals of each athlete.
