Design and validation of a tennis tool to control on-court technical and tactical training content
2021
In high performance tennis, different aspects like physical-conditioning, strategy-tactic, technical-biomechanical, psychology and skills acquisition have received large attention from the researchers. Nevertheless, the programming, periodization and planning of training sessions and competitions have not been as studied in depth. Coaches still use their experience, trial-error and subjective perceptions as methods of conducting these fundamental tasks. This article presents the design and validation of an instrument to control the technical and tactical training content on-court. The instrument was conceived by 9 experts and validated by 23 experienced coaches, who used on-court tennis ex…
A mismatch between athlete practice and current sports nutrition guidelines among elite female and male middle- and long-distance athletes
2017
Contemporary nutrition guidelines promote a variety of periodized and time-sensitive recommendations, but current information regarding the knowledge and practice of these strategies among world-class athletes is limited. The aim of this study was to investigate this theme by implementing a questionnaire on dietary periodization practices in national/international level female (n = 27) and male (n = 21) middle- and long-distance runners/race-walkers. The questionnaire aimed to gain information on between and within-day dietary choices, as well as timing of pre- and posttraining meals and practices of training with low or high carbohydrate (CHO) availability. Data are shown as percentage (%)…
Effects of HRV-Guided vs. Predetermined Block Training on Performance, HRV and Serum Hormones
2017
AbstractThe aim of this study was to compare heart rate variability -guided (HRVG) and predetermined (PD) block periodization of high intensity aerobic training (HIT). Endurance performance, neuromuscular performance, heart rate variability (HRV) and serum hormone concentrations were measured before, in the middle and after the 8-week training period in 24 endurance trained males. Both groups improved significantly maximal treadmill velocity (Vmax) (p<0.001) and 3000 m running performance (HRVG; p<0.001 and PD; p=0.001). The relative changes in Vmax and countermovement jump were significantly greater in HRVG (p<0.05). Nocturnal heart rate decreased in both groups (p<0.01), but H…
Episodes in the Berlin-Göttingen Rivalry, 1870-1930
2000
One of the more striking features in the development of higher mathematics at the German universities during the nineteenth century was the prominent role played by various rival centers. Among these, Berlin and Gottingen stood out as the two leading institutions for the study of research-level mathematics. By the 1870s they were attracting an impressive array of aspiring talent not only from within the German states but also from numerous other countries as well. The rivalry between these two dynamos has long been legendary, yet little has been written about the sources of the conflicts that arose or the substantive issues behind them. Here I hope to shed some light on this theme by recall…
Nutrition Knowledge Is Associated with Energy Availability and Carbohydrate Intake in Young Female Cross-Country Skiers
2021
The aim of this study was to provide information on energy availability (EA), macronutrient intake, nutritional periodization practices, and nutrition knowledge in young female cross-country skiers. A total of 19 skiers filled in weighted food and training logs before and during a training camp. Nutrition knowledge was assessed via a validated questionnaire. EA was optimal in 11% of athletes at home (mean 33.7 ± 9.6 kcal·kgFFM−1·d−1) and in 42% at camp (mean 40.3 ± 17.3 kcal·kgFFM−1·d−1). Most athletes (74%) failed to meet recommendations for carbohydrate intake at home (mean 5.0 ± 1.2 g·kg−1·d−1) and 63% failed to do so at camp (mean 7.1 ± 1.6 g·kg−1·d−1). The lower threshold of the pre-ex…
Les pobres Griseldes s?anaren empobrint amb els segles
2020
Resum: La figura literària de Griselda és mostra fefaent de la dona maltractada psicològicament. Des del conte de la literatura popular -font del Decameró-, tanmateix, ha anat canviant de status. A fi d’observar el recorregut als segles següents, cal partir de les versions medievals de Petrarca i de Boccaccio, lligades a la de Metge, ja que el relat es difon a través de les versions en llatí, italià i català. Per fer el seguiment temàtic en textos catalans, recorrem a documentació de caràcter popular o marginal, contrastant-la amb el curs dels relats griseldians, incloent alguns en castellà. De l’anàlisi desprenem que la defensa fermament humanística de la dona per part de Metge, manifesta …
Neuromuscular Responses to Short-Term Resistance Training With Traditional and Daily Undulating Periodization in Adolescent Elite Judoka.
2016
Ullrich, B, Pelzer, T, Oliveira, S, and Pfeiffer, M. Neuromuscular responses to short-term resistance training with traditional and daily undulating periodization in adolescent elite judoka. J Strength Cond Res 30(8): 2083-2099, 2016-The influence of different periodization models on neuromuscular outcomes after short-term strength training periods has not been examined in adolescent athletes. Eleven elite judoka (age: 14.8 ± 0.6 years, height: 163.2 ± 7.5 cm, body mass: 57.3 ± 11.1 kg, 5 boys/6 girls, and strength training experience: 2.7 ± 1.1 years) performed two 4-week strength training mesocycles (each with 12 sessions) with either traditional (TP) or daily undulating (DUP) periodizati…
Introduzione
2005
The Introductory word explains the role and scope of music historiography during the second half of 19th-Century Italy. At that time, historiographers were oriented to discover the value and the ideal place of musical oeuvre, rethinking music periodization through different paradigms and philosophies.

Teologiczna periodyzacja dziejów Kościoła w Chinach
2022
Periodyzacja teologiczna historii Kościoła w Chinach jest próbą określenia momentów granicznych różnych okresów życia chrześcijańskiego na podstawie kryterium teologicznego. Wiele prób periodyzacji przyjmuje kryteria polityczne, organizacyjne czy administracji kościelnej. Tymczasem na Dalekim Wschodzie tym, co decyduje o jakości i zakorzenieniu chrześcijaństwa, jest teologia rodzima, która posługuje się kulturą i językiem swojego narodu. W Chinach było wiele naprzemiennych okresów rozkwitu i prześladowań. Ponadto nie wszystkie okresy, określane przez historyków jako rozwój, były czasem rozkwitu teologii.
