Reactivity, stability, and strength performance capacity in motor sports

Background

Racing drivers require multifaceted cognitive and physical abilities in a multitasking situation. A knowledge of their physical capacities may help to improve fitness and performance.

Objective

To compare reaction time, stability performance capacity, and strength performance capacity of élite racing drivers with those of age‐matched, physically active controls.

Methods

Eight élite racing drivers and 10 physically active controls matched for age and weight were tested in a reaction and determination test requiring upper and lower extremity responses to visual and audio cues. Further tests comprised evaluation of one‐leg postural stability on a two‐dimensional moveable platform, measures of maximum strength performance capacity of the extensors of the leg on a leg press, and a test of force capacity of the arms in a sitting position at a steering wheel. An additional arm endurance test consisted of isometric work at the steering wheel at +30° and ?30° where an eccentric threshold load of 30?N.m was applied. Subjects had to hold the end positions above this threshold until exhaustion. Univariate one way analysis of variance (α ?=? 0.05) including a Bonferroni adjustment was used to detect group differences between the drivers and controls.

Results

The reaction time of the racing drivers was significantly faster than the controls (p ?=? 0.004). The following motor reaction time and reaction times in the multiple determination test did not differ between the groups. No significant differences (p>0.05) were found for postural stability, leg extensor strength, or arm strength and endurance.

Conclusions

Racing drivers have faster reaction times than age‐matched physically active controls. Further development of motor sport‐specific test protocols is suggested. According to the requirements of motor racing, strength and sensorimotor performance capacity can potentially be improved.
