Combined lower- and upper-limb post-activation performance enhancement does not clearly improve 50 m front crawl performance in national-level swimmers
Abstract Post-activation performance enhancement (PAPE) has been proposed as an acute strategy to improve sprint-swimming readiness, but the effects of combined lower- and upper-limb conditioning remain unclear. This study examined the acute effects of an individually timed combined lower- and upper-limb PAPE condition on 50 m front crawl performance and selected race-kinematic variables in national-level male swimmers.
Nationality patterns of the fastest marathon runners across age groups in the Berlin marathon
Abstract While the dominance of elite East African marathoners is well-established, little is known about the nationality distribution of the fastest age group marathoners. This study examined how the nationality distribution of the fastest marathon runners varies across age groups and sexes in the ‘Berlin Marathon’. We analysed race data from 825,886 finishers (627,962 men and 197,807 women) of the ‘Berlin Marathon’ from 1999 to 2024.
Sex differences in marathon pacing: analysis of 873,000 Berlin marathon runners reveals men are twice as likely to “hit the wall”
Abstract To determine whether sex differences in marathon pacing strategies and susceptibility to catastrophic deceleration (“hitting the wall”) persist in a massive, high-performance dataset, and to quantify this risk across different performance levels. We analyzed 873,334 finishers from the Berlin Marathon (1999–2025). Pacing stability was quantified using the percentage slowdown in the second half relative to the first. “Hitting the wall” was operationally defined as a deceleration of ≥ 20%.
Individually timed upper-limb post-activation performance enhancement improves 50 m front crawl performance in national-level swimmers
Abstract Post-activation performance enhancement (PAPE) has been proposed as an acute strategy to improve sprint performance, yet evidence in swimming remains inconsistent, particularly for upper-limb protocols and segment-specific race outcomes. This study examined the acute effects of an individually timed upper-limb PAPE procedure on 50 m front crawl performance and selected race-kinematic variables in national-level male swimmers.
Acute effects of an individually timed lower-limb post-activation performance enhancement protocol on 50 m front crawl performance and race kinematics in national-level swimmers
Abstract Post-activation performance enhancement (PAPE) has been proposed as an acute strategy to improve explosive performance, yet its effects on sprint-swimming performance remain unclear, particularly when individualized recovery timing is considered.
Pacing profiles and slowdown patterns in ultra-triathlon performance
Abstract Pacing in long-distance triathlon has been studied primarily for cycling and running in IRONMAN triathlon and daily-format ultra-triathlons, as managing fatigue is critical for success. However, no study has analysed pacing across all three disciplines in an ultra-triathlon such as the second-longest non-stop triathlon format, the Double Deca Iron ultra-triathlon covering 76 km swimming, 3600 km cycling, and 844 km running.
Athletes’ origin trends in participation and performance of master runners in the New York City marathon (1999–2024): a sex- and age-group analysis - Scientific Reports
Abstract It is well known that the fastest elite marathon runners come from East African countries such as Ethiopia and Kenya. However, to date, there is no information available on the origin of the fastest age group (master) marathoners. This study aimed to determine the countries of origin of the fastest age group marathoners who have participated in the ‘New York City Marathon’ over the past several decades.
Change in elevation predicts 100 km ultra marathon performance - Scientific Reports
Abstract The 100-km ultra-marathon is one of the most popular ultra-marathon distances. While we have a lot of scientific knowledge, no data exist about the influence of race course characteristics and other geographical aspects, on race performance.
Race course characteristics are the most important predictors in 48 h ultramarathon running - Scientific Reports
Abstract Ultra-marathon running - where races are held in distance-limited (50 km, 50 miles, 100 km, 100 miles, etc.), time-limited (6 h, 12 h, 24 h, 48 h, 72 h, etc.), and multi-stage races - is gaining in popularity. However, we have no knowledge of where the fastest 48-hour runners originate and where the fastest 48-hour races are held.
The association of origin and environmental conditions with performance in professional IRONMAN triathletes - Scientific Reports
Abstract We have (i) little knowledge about where the fastest professional IRONMAN triathletes originate from and where the fastest races take place and (ii) we have no knowledge of the optimal weather conditions for an IRONMAN triathlon.
The fastest nonprofessional age group IRONMAN triathletes in the world originate from Europe - Scientific Reports
Abstract It is well known that elite athletes of specific ethnicities and/or nationalities dominate certain sports disciplines (e.g., East Africans in marathon running). However, we do not know the nationalities of the fastest non-professional IRONMAN triathletes. Therefore, this study intended to identify the fastest athletes by country of origin competing in IRONMAN triathlon events, focusing on non-professional age group triathletes.
Europe has the fastest Ironman race courses and the fastest Ironman age group triathletes - Scientific Reports
Abstract The majority of participants in Ironman triathlon races are age group athletes. We have extensive knowledge about recreational athletes’ training and competition participation. Nonetheless, Ironman age group triathletes must achieve fast race times to qualify for the Ironman World Championship in Hawaii. They can, therefore, benefit from knowing where the fastest Ironman racecourses in the world are.
Analysis of the fastest backstroke age group swimmers competing in the World Masters Championships 1986–2024 - Scientific Reports
Abstract Backstroke has been thoroughly investigated in the context of sports science. However, we have no knowledge about the nationalities of the fastest age group backstroke swimmers. Therefore, the present study intended to investigate the nationalities of the fastest backstroke swimmers.
Influenza vaccination uptake among at‐risk patients in Switzerland-The potential of national claims data for surveillance
1 INTRODUCTION In accordance to the World Health Organization (WHO) recommendations,1, 2 vaccination against seasonal influenza is recommended in Switzerland for population groups at increased risk for complications such as people ≥65 of age or with chronic diseases.3 The increased risk in these groups is driven by many factors, for example, the decline in immune function and a reduced vaccine effectiveness.

Shared decision-making for prostate cancer screening and treatment: a systematic review of randomised controlled trials
Prostate cancer is one of the most serious public health concerns relating to men’s health worldwide. The World Health Organization (WHO) has declared prostate cancer to be the second most commonly diagnosed type of cancer in men, and the fifth leading cause of death due to cancer in men worldwide [1]. It accounts for 6.6% of the total deaths of men, and the burden is expected to increase to 1.7 million cases and 499?000 new deaths by 2030 globally [2].
Swiss Medical Weekly - Article
In most European countries, an increasing mismatch can be observed between, on the one hand, rising numbers of patients with chronic diseases [1] and, on the other hand, a shortage of general practitioners, who are mainly responsible for treating these patients [2]. In order to nevertheless enable complex health care and cope with rising costs, team-based approaches have been developed for treatment of the chronically ill.
Swiss Medical Weekly - Article
Since its creation, homeopathy has appeared to divide the medical community between supporters and opponents, and has spurred discussion about its effectiveness. Up to now, the mainstays of homeopathic doctrine have contradicted established principles of natural sciences, and comprehensible models consistently explaining how homeopathy could cause specific effects are lacking [1].
A Cross-Sectional Data Analysis | HTML
3, Twenty-six years ago, Schulz and Curnow investigated the age of Olympic gold medal winners in swimming, competing between 1896 and 1980 [ 1 ]. The average age in freestyle swimming was ~18 years for women and ~21 years for men [ 1 ]. This age remained stable for almost a century [ 1 ]. Nevertheless, over time humans have undergone changes in body dimensions such as body height, body mass and slenderness, and swimming performance has improved continuously across the years [ 2 4 ].
