Figure 2From: Effects of task and age on the magnitude and structure of force fluctuations: insights into underlying neuro-behavioral processes General properties of force production. Mean force (a), standard deviation (b), coefficient of variation (c), and signal-to-noise ratio (d), as a function of force level for young (in black) and older (in grey) participants. Each data point represents a group mean. Error bars represent the standard deviation.Back to article page
