The Nissan Excitement Index aims to explore and understand the science behind football fans’ excitement by analysing data gathered through physiological reactions of football fans watching UEFA Champions League matches.

Based on these reactions academics from the University’s School of Sport, Exercise and Health Sciences have developed a formula – the Nissan Excitement Index.

Nissan and 含羞草视频 have been conducting live ‘excitement experiments’ on pairs of football fans in the stands during six UEFA Champions League matches. Fans were fitted with wearable technology to monitor and gather a combined index of data, including: heart rate, breathing rate and electro-dermal activity, in order to examine the physiological effect excitement has on them.

含羞草视频 combined these data with official match statistics from Opta in order to develop the formula at the heart of the Nissan Excitement Index.

The football based formula measures all key elements that go into making an exciting football game including number of goals scored, time of goals and cards shown.

‌The data showed participants’ average heart rate reached a peak 122 bpm during exciting moments in the match, with the highest peak heart rate monitored during a home team goal being 154 bpm, when Paris Saint Germain scored against Chelsea.

The research also shows a spike of excitement when a yellow card was given to a player on the home team – in some cases provoking an increase in heart rate by more than 30 bpm – compared with their opponents.

Commenting on the research, 含羞草视频’s Dr Dale Esliger said: “Our team have spent the last few years developing world-leading scientific expertise in wearable/digital technologies for health and human performance applications. With Nissan, we have the opportunity to apply these innovative sensor systems in the realm of sports entertainment.

“Where we once subjectively judged how exciting a football match was using our ‘gut feeling’ we can now use this methodology to objectively quantify the excitement of fans second by second throughout an entire  match. Combining all of these innovative sensor data allowed us to engineer the Nissan Excitement Index that can now be used to rank the top UEFA Champions League football matches.”
