Abstract

Objective of the study is to examine the features of the influence of various motor instructions on the indicators of motor performance in ski jumpers. Methods and structure of the study. The assessment of the influence of motor instructions was carried out during pedagogical testing of three ski jumpers (age 23±3 years) who performed an upward jump from the "jumper's crouch" using the linear encoder of the Musclelab system. As control indicators, the values of force (N/kg), power (W/kg), height (cm) and take-off time (s), as well as maximum jump velocity (m/s), were recorded. During the mathematical processing of the results, the arithmetic mean and standard deviation (x±σ), dynamics indicators (absolute change (Δ) and relative change (%)) and the minimal detectable change indicator with a 95% confidence interval (MDC95) were calculated. Results and conclusions. The effect of motor instructions is determined by the level of sporting-technical mastery and preparedness of the ski jumper. Athletes of the "medium" level of preparedness have maximum reactivity to various motor instructions, while demonstrating positive responses to motor performance (force/jump velocity). The skill-based stabilisation of motor programmes, conditioned by the growth of sporting-technical mastery, reduces the effect of various motor instructions in relation to motor performance indicators.
