Assessment of the steady glide phase in ski jumping.
Elfmark O, Ettema G, Gilgien M. Elfmark O, et al. J Biomech. 2022 Jun;139:111139. doi: 10.1016/j.jbiomech.2022.111139. Epub 2022 May 17. J Biomech. 2022. PMID: 35609493 Free article.
The results for HS106 were in line with the assumptions in recent literature, which propose that the performance is largely determined by the take-off and glide preparation. Hence for normal hills, skiers should aim to reduce vertical acceleration through high aerodynamic …

Aerodynamic investigation of the inrun position in Ski jumping.
Elfmark O, Ettema G. Elfmark O, et al. Sports Biomech. 2024 Apr;23(4):455-469. doi: 10.1080/14763141.2020.1871503. Epub 2021 Feb 3. Sports Biomech. 2024. PMID: 33533308
This study aims to investigate the inrun position in ski-jumping, in search for factors increasing the inrun speed without compromising the take-off. The inrun position of eight World Cup (WC) and fifteen Continental Cup (COC) ski jumpers were investigated in a wind tunnel …

Performance Analysis in Ski Jumping with a Differential Global Navigation Satellite System and Video-Based Pose Estimation.
Elfmark O, Ettema G, Groos D, Ihlen EAF, Velta R, Haugen P, Braaten S, Gilgien M. Elfmark O, et al. Sensors (Basel). 2021 Aug 6;21(16):5318. doi: 10.3390/s21165318. Sensors (Basel). 2021. PMID: 34450758 Free PMC article.
The study had two aims; firstly, the agreement between the two methods was assessed using 16 jumps by athletes of national level from 5 m before the take-off to 20 m after, where the methods had spatial overlap. The comparison revealed a good agreement from 5 m after the …

Economic figures in herd health programmes as motivation factors for farmers.
Anneberg I, Østergaard S, Ettema JF, Kudahl AB. Anneberg I, et al. Prev Vet Med. 2016 Nov 1;134:170-178. doi: 10.1016/j.prevetmed.2016.10.007. Epub 2016 Oct 15. Prev Vet Med. 2016. PMID: 27836040
In the developing process, a prototype of the advisory tool was tested by 15 veterinarians on 55 farms. After the test period, a selection of farmers were asked to take part in a qualitative evaluation questioning them whether they had implemented the action plans suggeste …
