Is there meaningful influence from situational and environmental factors on the physical and technical activity of elite football players? Evidence from the data of 5 consecutive seasons of the German Bundesliga
Fig 2
Effects of WBGT and humidity on the technical and physical performance of players of different positions.
Effects are shown as the effect of an increase of two standard deviations in the value of WBGT and humidity on the standardised change score of each performance-related parameter. Dotted lines represent the smallest worthwhile change. Asterisks indicate the likelihood for the magnitude of the true effect as follows: ** likely; *** very likely; **** most likely. Asterisks located in the trivial area denote the likelihood of trivial effects.
