Figure 2From: Even low alcohol concentrations affect obstacle avoidance reactions in healthy senior individualsDetermination of response time and amplitude of the m. biceps femoris (BF). Response time was defined as the time between obstacle release (set at the origin of the axes) and the moment where the BF activity exceeded the activity of the control stride + 2SD. Average response amplitude was calculated over 100 ms after the onset of the response and normalized with respect to the average background activity.Back to article page
