The aim of this study was to investigate trends in participation, age, and performance in the longest inline race in Europe, the Inline One-E…
Fascicle-tendon interaction in v2 skate cross-country skiing : a case study
2015
Venymis-lyhenemis –sykli (SSC) on laajalti tutkittu liha-jänne -kompleksin (MTU) toimintamalli ihmisen liikkumisessa. Jotta SSC toiminta voidaan ymmärtää, lihaksen toiminta tulee mitata ultraäänen (US) avulla. Aiemmin yksi tutkimus on käsitellyt MTU:n toimintaa hiihdon aikana perinteisellä hiihtotavalla (Ishikawa, Sano et al. 2010). Tämän tutkimuksen tavoitteena on tarjota ainutlaatuinen kokeellinen tulos MTU:n toiminnasta vapaan hiihdon V2- tekniikan aikana, sekä tarjota suosituksia tulevaa tutkimusta varten. Tutkimuksessa yksi kokenut hiihtäjä suoritti protokolla Vuokatin hiihtotunnelissa. Protokolla koostui kahdesta eri mittauskerrasta, joiden välissä suoritettiin 20 km mittainen hiihtok…
Figure skating coaching in the contemporary sport culture : Finnish figure skating coaches' perceptions about their work
2016
Coaching as a profession in Finland in perceived as a challenging job. Lack of appreciation and support, scarce resources, and demanding working environment are placing coaches under a lot of pressure. In addition, coaches play a key role in the lives of their athletes and are therefore dealing with a variety of expectations and demands. These are not always set by the coaches themselves, but also from outside stakeholders, such as parents of the athletes, and national and international sport governing federations. On one hand coaches need to be demanding, authoritarian, and goal-oriented, but on the other hand, they need to be empathetic, friendly and supportive. During the past few decade…
Propulsion Calculated by Force and Displacement of Center of Mass in Treadmill Cross-Country Skiing
2022
This study evaluated two approaches for estimating the total propulsive force on a skier’s center of mass (COM) with double-poling (DP) and V2-skating (V2) skiing techniques. We also assessed the accuracy and the stability of each approach by changing the speed and the incline of the treadmill. A total of 10 cross-country skiers participated in this study. Force measurement bindings, pole force sensors, and an eight-camera Vicon system were used for data collection. The coefficient of multiple correlation (CMC) was calculated to evaluate the similarity between the force curves. Mean absolute force differences between the estimated values and the reference value were computed to evalua…
Predictor variables of performance in recreational male long-distance inline skaters.
2011
We investigated the associations between selected anthropometric and training characteristics with race time in 84 recreational male long-distance inline skaters at the longest inline marathon in Europe, the 'Inline One-eleven' over 111 km in Switzerland, using bi- and multivariate analysis. The mean (s) race time was 264 (41) min. The bivariate analysis showed that age (r = 0.30), body mass (r = 0.42), body mass index (r = 0.35), circumference of upper arm (r = 0.32), circumference of thigh (r = 0.29), circumference of calf (r = 0.38), skin-fold of thigh (r = 0.22), skin-fold of calf (r = 0.27), the sum of skin-folds (r = 0.43), percent body fat (r = 0.45), duration per training unit in in…
Taitoluistelu mahdollisena sponsoroinnin kohteena
2016
Salmijärvi, S. 2016. Taitoluistelu mahdollisena sponsoroinnin kohteena. Liikuntakasvatuksen laitos, Jyväskylän yliopisto, liikunnan yhteiskuntatieteiden pro gradu -tutkielma, 115 s., 1 liite. Tutkielmassa tarkasteltiin urheilun sponsorointia yhden lajin, taitoluistelun, näkökulmasta. Tutkielmassa selvitettiin, millainen mahdollinen sponsoroinnin kohde taitoluistelu on ja miksi. Tavoitteena oli tuottaa urheilusponsorointiin liittyvää tieteellistä tietoa uudenlaisesta näkökulmasta ja tarjota samalla Suomen Taitoluisteluliitto ry:lle hyödyllinen katsaus taitoluistelun tilanteeseen. Tutkielmassa perehdyttiin aiempaan kirjallisuuteen niin sponsoroinnin kuin taitoluistelunkin osalta sekä selvitet…
Neuromuscular Adaptations to Short-Term High-Intensity Interval Training in Female Ice-Hockey Players
2019
Kinnunen, J-V, Piitulainen, H, and Piirainen, JM. Neuromuscular adaptations to short-term high-intensity interval training in female ice-hockey players. J Strength Cond Res 33(2): 479-485, 2019-High-intensity interval training (HIIT)-related neuromuscular adaptations, changes in force production, and on-ice performance were investigated in female ice-hockey players during preseason. Fourteen Finnish championship level ice-hockey players (average age 22 ± 3 years) participated in 2½-week HIIT. Both spinal (H-reflex) and supraspinal (V-wave) neuromuscular responses of the soleus muscle were recorded before and after the training period. Static jump (SJ) and countermovement jump heights, plant…
Age, training, and previous experience predict race performance in long-distance inline skaters, not anthropometry
2012
Knechtle, Beat | Knechtle, Patrizia | Ruest, Christoph Alexander | Rosemann, Thomas | Lepers, Romuald; International audience; ''The association of characteristics of anthropometry, training, and previous experience with race time in 84 recreational, long-distance, inline skaters at the longest inline marathon in Europe (111 km), the Inline One-eleven in Switzerland, was investigated to identify predictor variables for performance. Age, duration per training unit, and personal best time were the only three variables related to race time in a multiple regression, while none of the 16 anthropometric variables were related. Anthropometric characteristics seem to be of no importance for a fast …
Validation of 2D Force Measurement Roller Ski and Practical Application.
2022
Several methods could be used to measure the forces from skis or roller skis in cross-country skiing. Equipment that could measure medio-lateral forces may be of good help for investigating the relevant skating techniques. The aim of this study was to validate a pair of newly designed two-dimensional force measurement roller skis. The vertical and medio-lateral forces which were perpendicular to the body of the roller ski could be measured. Forces were resolved into the global coordinate system and compared with the force components measured by a force plate. A static and dynamic loading situation for the force measurement roller ski was performed to reveal the validity of the system. To de…
Is Body Fat a Predictor of Race Time in Female Long-Distance Inline Skaters?
2010
Purpose The aim of this study was to evaluate predictor variables of race time in female ultra-endurance inliners in the longest inline race in Europe. Methods We investigated the association between anthropometric and training characteristics and race time for 16 female ultra-endurance inline skaters, at the longest inline marathon in Europe, the ‘Inline One-eleven’ over 111 km in Switzerland, using bi- and multivariate analysis. Results The mean (SD) race time was 289.7 (54.6) min. The bivariate analysis showed that body height (r=0.61), length of leg (r=0.61), number of weekly inline skating training sessions (r=-0.51) and duration of each training unit (r=0.61) were significantly correl…
