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 4
Effects of weather condition on the technical and physical performance of players of different positions.
Effects are shown as the standardised difference in each performance-related parameter when playing in light-rain, heavy-rain, and snowy conditions vs playing in sunny conditions. Bars are 99% compatibility intervals. Dotted lines represent the smallest worthwhile difference. Asterisks indicate the likelihood for the magnitude of the true effect as follows: * possible; ** likely; *** very likely; **** most likely. Asterisks located in the trivial area denote the likelihood of trivial effects.
