Changes in different salivary biomarkers related to physiologic stress in elite handball players: the case of females
2019
AbstractThis study evaluates pre- and post-match concentrations of salivary cortisol, alpha-amylase (AA) and immunoglobulin A (lgA) in a group of 21 elite female handball players in the Spanish national women’s league. The players’ mean age was 23.0 ± 5.4 years. The concentration of the biomarkers was determined using ELISA. Mean playing time was 25.2 min. The players’ cortisol concentration increased significantly (p < 0.05) whereas the IgA concentration fell significantly (p < 0.01) at the end of the match. There were no significant changes in the concentrations of AA between pre and post-match timepoints. The changes observed in the study also depended on the position played; defen…
Impact of a 4-Week Intensified Endurance Training Intervention on Markers of Relative Energy Deficiency in Sport (RED-S) and Performance Among Well-T…
2020
Cyclists often apply block periodization to high training volumes in meso- and macrocycles to optimize training adaptation and to prepare for competition. Body mass influences performance in many sports, including endurance disciplines, and conditions related to the syndrome Relative Energy Deficiency in Sports (RED-S) such as metabolic adaptations and premature osteoporosis have also been reported in male cyclists. This study aimed to determine how a 4-week mesocycle of intensified endurance training designed to increase performance, would affect markers of RED-S in well-trained male cyclists. Twenty-two participants (age: 33.5 ± 6.6 years, height: 181.4 ± 5.2 cm, weight: 76.5 ± 7.4 kg, pe…
Technical, tactical and movement analysis of men's professional tennis on hard courts.
2018
Background There is very little information in tennis relating performance to both the movement of the players and the effectiveness of their shots. This study aimed to identify differences between winners and losers in the volume and intensity of their movements, as well as in the effectiveness of their shots. Methods Matches (N.=8) at the 2011 ATP 500 tournament in Valencia (Spain) were recorded and analyzed using SAGIT, a computerized vision-tracking system. Data were split into points for movement analysis, and into games for stroke analysis. Results Players winning points used more offensive strategies and spent more time in the offensive zone than point losers. They also forced point …
''The age-related decline in Olympic distance triathlon performance differs between males and females''
2013
Etter, F. | Knechtle, B. | Ruest, C. A. | Rosemann, T. | Lepers, R.; International audience; ''Aim. The aim of this cross-sectional study was to compare the age-related declines in swimming, cycling, and running and overall race times between males and females in an Olympic distance triathlon, the 'Zurich Triathlon' in Switzerland. Methods. Swimming (1.5 km), cycling (40 km), running (10 km) and overall race times of 7939 total finishers (1666 females and 6273 males) from 2000 to 2010 in the "Zurich Triathlon" were analysed. Results. There was a significant (P50 years) 5 for cycling (>40 years) and for overall race time (>40 years). Conclusion. These data suggest that the age and gender int…
''Sex-related Trends In Participation and Performance In the 'swiss Bike Masters' From 1994-2012''
2013
Gloor, Roman Urs | Knechtle, Beat | Knechtle, Patrizia | Ruest, Christoph Alexander | Haupt, Samuel | Rosemann, Thomas | Lepers, Romuald; International audience; ''General participation in contests such as ultra-marathons and ultra-triathlons has increased considerably over the past 30 years, especially among women. This study investigated performance trends in the Swiss Bike Masters, one of the first and most prestigious mountain bike, ultra-endurance races in its class, with comparisons of participation and performance trends to similar races. The development of performance in the Swiss Bike Masters held between 1994 and 2012 was investigated by analysing the number of finishers, their ag…
Runners in their forties dominate ultra-marathons from 50 to 3,100 miles
2014
International audience; OBJECTIVES: This study investigated performance trends and the age of peak running speed in ultra-marathons from 50 to 3,100 miles. METHODS: The running speed and age of the fastest competitors in 50-, 100-, 200-, 1,000- and 3,100-mile events held worldwide from 1971 to 2012 were analyzed using single- and multi-level regression analyses. RESULTS: The number of events and competitors increased exponentially in 50- and 100-mile events. For the annual fastest runners, women improved in 50-mile events, but not men. In 100-mile events, both women and men improved their performance. In 1,000-mile events, men became slower. For the annual top ten runners, women improved in…
The age-related performance decline in ultraendurance mountain biking
2013
Haupt, Samuel | Knechtle, Beat | Knechtle, Patrizia | Ruest, Christoph Alexander | Rosemann, Thomas | Lepers, Romuald; International audience; ''The age-related changes in ultraendurance performance have been previously examined for running and triathlon but not mountain biking. The aims of this study were (i) to describe the performance trends and (ii) to analyze the age-related performance decline in ultraendurance mountain biking in a 120-km ultraendurance mountain bike race the Swiss Bike Masters from 1995 to 2009 in 9,325 male athletes. The mean (+/- SD) race time decreased from 590 +/- 80 min to 529 +/- 88 min for overall finishers and from 415 +/- 8 min to 359 +/- 16 min for the top …
''Sex Difference In Open-water Ultra-swim Performance In the Longest Freshwater Lake Swim In Europe''
2013
Eichenberger, Evelyn | Knechtle, Beat | Knechtle, Patrizia | Ruest, Christoph A. | Rosemann, Thomas | Lepers, Romuald | Senn, Oliver; International audience; ''This study examined participation and performance trends in the 26.4-km open-water ultra-swim "Marathon Swim in Lake Zurich," Switzerland. A total of 461 athletes (157 women and 304 men) finished the race between 1987 and 2011. The mean age of the finishers during the studied period was 32.0 +/- 6.5 years for men and 30.9 +/- 7.2 years for women. The mean age of finishers and the age of winners increased significantly across years for both sexes (p 0.05). The swimming time performance remained stable (p > 0.05) for both sexes across …
Effects of a trail running competition on muscular performance and efficiency in well-trained young and master athletes
2010
International audience; To determine the acute effects of a trail running competition and the age-dependent differences between young and master athletes, 23 subjects [10 young (30.5 ± 7 years), 13 master (45.9 ± 5.9 years)] participated in a 55-km trail running competition. The study was conceived as an intervention study compromising pre, post 1, 24, 48 and 72 h measurements. Measurements consisted of blood tests, ergometer cycling and maximal isometric voluntary contractions (MVC). Parameters monitored included MVC, twitch-and M-wave properties, EMG (RMS) of the vastus lateralis, two locomotion efficiency calculations and muscle damage markers in the blood (CK, LDH). Results indicate pos…
A BRIEF NOTE ON THE RELATIONSHIP BETWEEN ANXIETY AND PERFORMANCE IN SCUBA DIVING IN ADOLESCENTS: A FIELD STUDY.
2015
This study explored the relationship between anxiety and scuba diving performance of young individuals ( N = 44; 16.9yr., SD = 1.2) participating in an introductory scuba diving activity. The question was whether the well-known negative correlation between anxiety and scuba diving performance found for experienced and middle-aged scuba divers will be observed in young participants in their first dive experience. Diving instructors rated standardized scuba diving skills that were correlated with individual state and trait anxiety. There was no relationship between anxiety and scuba diving performance, neither for state nor for trait anxiety. This non-significant correlation between anxiety …
