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…
Nutritional intake and anthropometric characteristics are associated with endurance performance and markers of low energy availability in young femal…
2023
Background Low energy availability (LEA) can have negative performance consequences, but the relationships between LEA and performance are poorly understood especially in field conditions. In addition, little is known about the contribution of macronutrients to long-term performance. Therefore, the aim of this study was to evaluate if energy availability (EA) and macronutrient intake in a field-based situation were associated with laboratory-measured performance, anthropometric characteristics, blood markers, training volume, and/or questionnaire-assessed risk of LEA in young female cross-country (XC) skiers. In addition, the study aimed to clarify which factors explained performance. Metho…
Kaksoisuraa pitkin tulevaisuuden ammattilaiseksi
2022
Kaksoisuralla tarkoitetaan tavoitteellisen urheilun ja opiskelun tai työuran yhdistämistä. Suomessa kaksoisura alkaa yläkouluvaiheessa jatkuen urheilu-uran päättymisen jälkeiseen urasiirtymään. Urheilun ja opiskelun yhdistäminen voi olla esimerkiksi räätälöityjä opintoja ammattioppilaitoksessa tai korkeakoulussa. (Suomen Olympiakomitea.) nonPeerReviewed
