Hemoglobin mass and performance responses during 4 weeks of normobaric “live high–train low and high”
2023
Purpose To investigate whether 4 weeks of normobaric “live high–train low and high” (LHTLH) causes different hematological, cardiorespiratory, and sea-level performance changes compared to living and training in normoxia during a preparation season. Methods Nineteen (13 women, 6 men) cross-country skiers competing at the national or international level completed a 28-day period (∼18 h day−1) of LHTLH in normobaric hypoxia of ∼2400 m (LHTLH group) including two 1 h low-intensity training sessions per week in normobaric hypoxia of 2500 m while continuing their normal training program in normoxia. Hemoglobin mass (Hbmass) was assessed using a carbon monoxide rebreathing method. Time to exhaust…
Physical fitness and anthropometrics in Finnish soldiers during their early career: prospective changes during a 3-year follow-up.
2020
IntroductionPhysical fitness is a fundamental capability required of military personnel, but studies focusing on longitudinal changes in physical fitness and anthropometrics in soldiers are lacking. The aim was to evaluate physical fitness and anthropometrics in soldiers during their early career.MethodsA 3-year prospective study included 180 male soldiers (baseline age 26±2 years) with measures of a 12 min running test, standing long jump, sit-up and push-up tests, and body mass, height and waist circumference (WC). Baseline data were stratified into tertiles, and the changes within each tertile were analysed using dependent t-tests and analysis of variance.Results12 min running test dista…
Mental Skills of an Athlete as a Resource of Professional Longevity in Sport
2021
The aim of the study was to assess associations between dimensions of mental skills, psychological readiness and predictors of career longevity among current athletes. Mental skills dimensions were measured with the Ottawa Mental Skills Assessment Tool (OMSAT). The psychological predictors of athletic career longevity were measured with the Athletic Coping Skills Scale-28 (the ACSI-28) producing scores for seven coping skills and with the Competitive State Anxiety Inventory-2 (CSAI-2) which produced scores for confidence in competition. Overall, 253 current athletes (average age 22 years) of various competitive levels (classified to 5 groups according to the national sport classification sy…
Performance-related physiological changes induced by one year of endurance training in young athletes
2023
IntroductionAlthough maximal oxygen uptake (VO2max) is generally recognized as the single best indicator of aerobic fitness in youth, interpretation of this parameter and the extent to which it can be improved by training remain controversial, as does the relative importance of VO2max for performance in comparison to other factors such as power production. Here, we examined the influence of endurance training on the VO2max, muscle power and sports-related performance of cross-country skiers attending a school specializing in sports, as well as potential relationships between any changes observed to one another and/or to perceived stress scale (Cohen) and certain blood parameters.MethodsOn t…

La federazione italiana gioco calcio è un organismo di diritto pubblico? Il vaglio della Corte di giustizia
2021
l presente contributo affronta il tema della inquadrabilità della Federazione Italiana Gioco Calcio nell’ambito della figura dell’organismo di diritto pubblico, prendendo spunto da una recente sentenza della Corte di giustizia e dai quesiti ad essa posti dalle ordinanze di rinvio del Consiglio di Stato. Tra ordinanze di rinvio, Conclusioni dell’Avvocato generale e giudizio della Corte emergono i tratti essenziali del particolare rapporto tra federazioni sportive e CONI, oltre che importanti precisazioni su ciò che debba essere inteso per vigilanza sulla gestione delle federazioni (vigilanza come controllo attivo, idoneo a influire sulle decisioni delle federazioni stesse in materia di appal…
Suplementy diety dla sportowców w aspekcie przepisów antydopingowych
2022
Motywacja w zakresie stosowania suplementów diety w sporcie jest duża i silnie skorelowana z potrzebą osiągania coraz lepszych wyników przez konsumenta. Dane pochodzące z Centrum Badań Opinii Społecznej wskazują, że dziewięciu na dziesięciu dorosłych Polaków stosuje suplementację, a sportowcy wielokrotnie sięgają po kilka suplementów jednocześnie. Korzystanie z suplementów zależy przede wszystkim od rodzaju uprawianej dyscypliny sportowej i wzrasta wraz z intensywnością treningu oraz wiekiem respondentów. Opublikowane dane sugerują również, że sportowcy są skłonni przyjmować suplementy bez gromadzenia wiarygodnych informacji o zawartych w nich substancjach aktywnych. Dlatego w historii spor…

Hamstring Graft Preparation for ACL Reconstruction
2022
Anterior cruciate ligament (ACL) reconstruction represents one of the most common procedures in orthopedic surgery. It usually involves the harvest of both gracilis and semitendinosus tendons from the ipsilateral knee. Different methods of hamstring graft preparation have been proposed in recent years, to create an adequate graft diameter reducing morbidity linked to gracilis tendon harvesting procedure. More recently, the use of only 1 of the tendons (semitendinosus) in a tripled or quadrupled arrangement has been described, especially in an all-inside type of reconstruction. Having a thicker tendon with a quadrupled semitendinosus (ST), instead of double gracilis and ST enables to have a …
