Does periodization work? Athletes perform better in major events than in minor competitions
2021
Previous studies on periodization have led to the view that most athletes fail to peak at major events. These conclusions might be based on definitions of “peak performance” that are too narrow. In this study, a track and field athlete was defined as succeeding in a competition if their outcome was within the acceptable range from the best result of the season. The data are from seven championship finals and semifinals together with 42 Diamond League competitions from the 2010s, altogether 7,087 individual results. All field events and running events up to 400 m were included. The majority of athletes succeeded in major events (67.0% in sprint and 57.5% in field events). Overall, champions…
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…
Effects of a 10-day high-intensity interval training mesocycle on physical performance in male judo athletes
2020
Judo is an Olympic combat sport where the competition emphasizes several consecutive 20-30 seconds high-intensity efforts interspersed by short recovery periods. High-intensity block training has been found to be an efficient way to develop physical performance, wherein shorter training periods are focused on developing one or two chosen physical abilities. The purpose of this study was to investigate the effects of a 10-day high-intensity interval training period on the performance in male judo athletes. The study included pre and post-tests as well as a 10-day training intervention. The subjects were 19-28 years old men who had competed at least at the Nordic level during the last year (n…
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 (%)…
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.
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…
Traditional vs daily undulling periodization in strength and local muscle endurance gains on trained men
2018
The aim of this study was to investigate the impact of different periodization models on strength and local muscle endurance. Twenty trained men (25.45 ± 2.984 years, 75.34 ± 6.05 kg, 177.25 ± 4.92 cm, 23.96 ± 1.64 kg . m-2) were randomly assigned in two groups: undulling periodization (UPG) and traditional periodization group (TPG), respectively. All the subjects performed one repetition maximum (1-RM) strength test and a local muscle endurance test (60% of 1-RM to failure) before, during and after experimental period. The UPG executed 30 workout sessions with daily modifications regarding intensity, volume and rest period length. The TGP was divided into 3 phases (10 workout sessions in e…
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…
Effects of Including Sprints in One Weekly Low-Intensity Training Session During the Transition Period of Elite Cyclists
2020
The purpose of this study was to investigate the effects of including 30-s sprints in one weekly low-intensity training (LIT) session during a 3-week transition period in elite cyclists. Sixteen male elite cyclists (maximal oxygen uptake, VO2max: 72 ± 5 ml·kg−1·min−1) reduced their training load by ~60% for 3 weeks from the end of competitive season and performed only LIT or included 30-s sprints (SPR) in one weekly LIT-session. Performance and physiological capacities were evaluated during a prolonged (~2.5 h) test-session, including a strength test, a submaximal blood lactate profile test, an incremental test to exhaustion to determine VO2max, 1 h continuous cycling including four maximal…
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.
