BiomekaniikkaThe purpose of this thesis was to identify technical determinants of elite level
air rifle and biathlon standing shooting performance and investigate how these
technical determinants are affected by training, competition situation, or intense
exercise. Forty international and national level air rifle shooters and 17
biathletes participated in the studies. In air rifle shooting, shooting performance,
aiming point trajectory, and postural balance were measured from each shot in
a simulated competition series in the training situation and in the actual
competition situation. The shooters’ competition results were collected from
each measured season. In biathlon, the same shooting technical variables were
measured in rest and in shooting after competition simulation roller skiing task.
Horizontal stability of hold, aiming accuracy, timing of triggering, and
cleanness of triggering were the most important technical determinants of elite
level air rifle shooting performance, explaining 81% of the variance in shooting
score. Postural balance was related to air rifle shooting performance directly,
and indirectly through more stable hold and cleaner triggering. Shooting
technique test measures were related to the competition results achieved during
the season. Long term shooting training improved stability of hold, aiming
accuracy, cleanness of triggering, and postural balance. All these aspects of
shooting technique deteriorated in competition compared to training situation.
In biathlon standing shooting, vertical stability of hold and cleanness of
triggering were related to shooting performance, and postural balance affected
both of these components. Intense exercise decreased biathlon standing
shooting performance and all shooting technical components except timing of
triggering. The decrease in shooting technical components was related to the
decrease in postural balance. The elite level shooters’ reference values presented
in the thesis can be used by athletes and coaches in pursuing superior rifle
shooting technique and in assessing shooters’ technical strengths and
weaknesses. The results also demonstrated the importance of psychological
skills, since all the progress made through technique training could be lost in
the competition situation. Postural balance is one clear aspect which affects the
important shooting technical components both in air rifle and biathlon shooting.

Does periodization work? Athletes perform better in major events than in minor competitions
Matomäki, Pekka; Räntilä, Aapo (SAGE Publications, 2022)Previous studies on periodization have led to the view that most athletes fail to peak at major events. These conclusions might be based on definitions of “peak performance” that are too narrow. In this study, a track and ... -
Aiming strategy affects performance-related factors in biathlon standing shooting
Köykkä, Miika; Ihalainen, Simo; Linnamo, Vesa; Ruotsalainen, Keijo; Häkkinen, Keijo; Laaksonen, Marko S. (Wiley, 2021)This study focused on investigating differences in shooting performance and performance related factors between two different aiming strategies (HOLD, low radial velocity during the approach 0.4‐0.2 seconds before triggering, ... -
Biathlon standing shooting performance, shooting technical components and postural balance at rest and during a race simulation
Köykkä, Miika (2018)Stability of hold and postural balance have been reported to be related to standing shooting performance, and to differentiate between different experience levels of biathletes. Recently, ability to minimize the movement ... -
Technical determinants of biathlon standing shooting performance before and after race simulation
Ihalainen, Simo; Laaksonen, Marko S.; Kuitunen, Sami; Leppävuori, Antti; Mikkola, Jussi; Lindinger, Stefan Josef; Linnamo, Vesa (Wiley-Blackwell Publishing Ltd., 2018)The aim of this study was to identify performance- determining factors in biathlon standing shooting in rest and after intense exercise. Eight Finnish national- and nine junior- team biathletes participated in the study. ... -
Performance‐determining factors in biathlon prone shooting without physical stress
Köykkä, Miika; Laaksonen, Marko S.; Ihalainen, Simo; Ruotsalainen, Keijo; Linnamo, Vesa (Wiley, 2022)This study investigated the most important factors determining biathlon prone shooting performance. 10 female and 16 male biathletes (age 19.9 ± 2.9 years) from the national teams of Finland and Vuokatti-Ruka Sports Academy ...
