- Physiological features of olympic-distance amateur triathletes, as well as their associations with performance in women and men: a cross-sectional studyPublication . Barbosa, José Geraldo; Lira, Claudio A.B. de; Vancini, Rodrigo Luiz; Anjos, Vinicius R. dos; Vivan, Lavinia; Seffrin, Aldo; Forte, Pedro; Weiss, Katja; Knechtle, Beat; Andrade, Marilia SantosThe purpose of this study was to verify the physiological and anthropometric determinants of triathlon performance in female and male athletes. This study included 40 triathletes (20 male and 20 female). Dual-energy X-ray absorptiometry (DEXA) was used to assess body composition, and an incremental cardiopulmonary test was used to assess physiological variables. A questionnaire about physical training habits was also completed by the athletes. Athletes competed in the Olympic-distance triathlon race. For the female group, the total race time can be predicted by V?O(2)max (beta = -131, t = -6.61, p < 0.001), lean mass (beta = -61.4, t = -2.66, p = 0.018), and triathlon experience (beta = -886.1, t = -3.01, p = 0.009) (r(2) = 0.825, p < 0.05). For the male group, the total race time can be predicted by maximal aerobic speed (beta = -294.1, t = -2.89, p = 0.010) and percentage of body fat (beta = 53.6, t = 2.20, p = 0.042) (r(2) = 0.578, p < 0.05). The variables that can predict the performance of men are not the same as those that can predict the triathlon performance of women. These data can help athletes and coaches develop performance-enhancing strategies.
- There are the fastest master butterfly swimmers competing in the fina world masters championships from?Publication . Weiss, Katja; Seffrin, Aldo; Andrade, Marilia Santos; Ahmad, Wais; Forte, Pedro; Moreitz, Sascha; Stanula, Arkadiusz; Cuk, Ivan; Nikolaidis, Pantelis Theo; Knechtle, BeatWhile the butterfly stroke has received considerable attention in sports science, the origin of the fastest master butterfly swimmers remains unknown. The present study investigated which geographical locations produce the top-performing master butterfly swimmers within their age groups and gender. A total of 26,512 master butterfly swimmers (11,288 women and 15,224 men) competed in 50 m, 100 m and 200 m races in World Masters Championships held between 1986 and 2019. From each swimmer, the year of competition, first name, last name, age group and distance were recorded. Descriptive data were presented using mean, standard deviation, maximum and minimum values, and/or confidence intervals. The top 10 race times for master butterfly swimming and gender were identified for descriptive purposes. Nationalities were then grouped into six categories: the top five nationalities with the most appearances in the top 10 fastest times in butterfly swimming by distance each year and one group consisting of all other nationalities. In the event of a tie, the nationality with the most participants overall was selected. Generalized linear models (GLMs) with a gamma probability distribution and log link function were used to assess the effect of age groups and gender on swimming time. In summary, Germany had the fastest women butterfly master swimmers across all distances, while the USA had the fastest men butterfly master swimmers for all distances. Men covered all distances faster than women and younger swimmers were quicker than older swimmers. The results of this study can be utilized to determine the countries that produce the most successful master butterfly swimmers, providing a foundation for further research to explore the factors that lead to their success.
