The PACINPAT study: physical activity counselling in in-patients with major depressive disorders

Major depressive Disorder (MDD) is a widespread and burdensome disease. People with MDD suffer from loss of interest and pleasure in activities that they would usually enjoy. In addition, they report anxiety, complex somatic pain syndromes, cognitive restrictions, loss of sexual interest, impaired sleep and social withdrawal. MDD is the leading cause for years lived with disability (YLD) in women and men and has a lifetime prevalence of 10-20 %.

Fluctuations in the results of ferritin analysis between six different medical laboratories

Introduction: Iron is an important factor of the energy balance and correlates with serum ferritin. For competitive athletes, ferritin measurements are regularly performed at certified medical laboratories. However, as a laboratory change happened, we questioned the validity of ferritin levels, since unusually high values were measured. The aim of this study is to compare the ferritin values of blood samples in six different laboratories and to evaluate the diagnosis of iron deficiency. Methods: Blood samples from 63 patients with suspected iron deficiency were sent to six laboratories for ferritin measurements.

Iron deficiency in athletes – new guidelines for diagnosis and treatment

Background: Iron deficiency (ID), worldwide a common affection is associated with reduced performance, fatigue and increased risk for infections. Athletes are a risk-population due to a higher prevalence of restrictive diets or exercise-induced inflammation. Particularly in athletes, the diagnosis of ID based on unspecific symptomes or routine laboratory diagnostics with ferritin is not always reliable. The goal of this study was therefore to discover if a new diagnostic approach adding zinc protoporphyrin (ZnPP) or soluble transferrin receptor (sTfR) in the routine assessment of ID in athletes is helpful or even necessary.

Sex-specific reaction of the cardiac autonomic nervous system to different training phases in Swiss elite runners

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).

Challenges with the biological passport: from sampling to interpretation

In 2008, the World Anti-Doping Agency officially launched the biological passport. The first validated module to operate was the blood module to fight erythropoietin (EPO) and blood transfusion abuse. It has been quite efficient to catch some doped athletes, but above all, was very good in reducing the prevalence of doping. It is unclear if athletes stopped doping or have adapted and are taking micro doses of EPO or transfusing small blood volumes. More recently, the steroid module was released, but until now, the number of urine adverse passport cases is very low.

Retesting the anti-doping samples: Best tool for deterrence?

Long term storage of the anti-doping samples and their reanalyses becomes today more and more a trend in the anti-doping community. The procedure has been implemented by the anti-doping authorities for the samples of the Tour de France and for the Olympic Games since Athens 2004 and has been always presented as a good tool to deter doping habits in top level sport. Recently, the World Anti-Doping Code introduced the possibility for anti-doping organizations to store the athletes’ samples up to ten years.

Effectiveness of an online tailored intervention on determinants and behaviour to prevent running related sports injuries: a randomised controlled trial

Objective. Sports injuries are one of the most common injuries in the modern Western society. In line with the increased interest in eHealth, a tailor-based online injury prevention intervention was developed to influence determinants and actual sports injury preventive behaviour. An effect study was carried out among runners. Methods. Runners between 18 and 35 years were randomly assigned to the intervention (n=109) or control group (n=105). Participants in the intervention group were invited to visit the website for 30 minutes. Those in the control group were invited to read magazines that did not contain information about running, injuries or other sport related issues for 30 minutes.

Reliability and Validity of Two Measurement Systems in the Quantification of Jump Performance

There are different devices on the market for assessing strength and power in vertical jumping as a fundamental requisite of an athlete’s performance. The purpose of this study was to assess the reliability and validity of two instruments measuring force, power, velocity, and jump height in squat jumps. Myotest® (MYO) (Myotest SA, Switzerland) was compared with force plate measurements (Quattro Jump® [QUATTRO], Kistler, Switzerland & SPSport Software, Trins, Austria). Forty-three frontier-guards (age range 25–58 years) performed twice a series of five squat jumps (SJ) simultaneously using MYO device along with QUATTRO force plate. Reliability was analysed using ICC, CV and RMSE. Results for reliability for both devices show good results with ICCs ranging from 0.910 to 0.955, and CVs ranging from 2.33% to 6.59% for discrete outcome variables.
