Effects of HRV-Guided vs. Predetermined Block Training on Performance, HRV and Serum Hormones

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…

Urheilulukiolaisten siirtymä varhaisaikuisuuteen : identiteetin yhteys urheilun ja opintojen jatkamiseen

Siirtymä varhaisaikuisuuteen tuo urheilijoiden elämään useita muutoksia, joiden vuoksi todennäköisyys lopettaa tavoitteellinen kilpaurheilu-ura kasvaa. Tämän tutkimuksen tarkoituksena oli selvittää, kuinka suuri osa urheilulukion vuonna 2015 aloittaneista nuorista jatkoi yhtäältä tavoitteellista kilpaurheilua ja toisaalta opintoja lukion jälkeen varhaisaikuisuudessa sekä olivatko sukupuoli ja lajimuoto (yksilö- vai joukkuelaji) yhteydessä jatkamiseen. Lisäksi tutkittiin, ennustivatko lukioaikaiset urheilija- ja opiskelijaidentiteetit kilpaurheilun ja opintojen jatkamista. Tutkimus on osa Jyväskylän yliopiston Winning in the long run -pitkittäistutkimusta, jonka seurantavaihe toteutettiin sy…

The role of career adaptability resources in dual career pathways: A person-oriented longitudinal study across elite sports upper secondary school

Objectives Obtaining education is an important milestone in athletes’ preparation for their professional career after sport. Literature indicates that combining school and sport is not an easy task for many aspiring youth athletes. It has been proposed that career adaptability, which refers to psychosocial resources enabling individuals to solve complex occupational transitions, present and anticipated vocational development tasks, and career related challenges could be a relevant concept for applied work with student-athletes. In this study, we examined whether there are distinct developmental profiles of career adaptability among adolescent athletes across the upper secondary school years…

Exploring the Life Form of a Student Athlete Afforded by a Dual Career Development Environment in Finland

The current paper introduces a case study conducted in one of the most well-established athletic talent development environments in Finland, with the focus on the environment’s ecological dynamics and organizational culture, in light of its recent effort to rebrand itself as a dual career development environment. Our analysis has been inspired by the holistic ecological approach and ecological dynamics, wherein the authors have considered a dual career development environment from the point of view of its transactions with agentic individuals and affordances for student athletes in the study domain, the sports domain, and the private domain. The authors believe our findings can provide othe…
