World champions! The Chicago Cubs turn to wearable sleep tech for edge in MLB pursuit

Update Nov 3, 2016:

Since this post was written, The Cubs of course have gone on to make history… after 108 years! Congratulations Cubs from everyone at Fatigue Science. We’ll be covering more of your amazing story in the very near future.

The Chicago Cubs are among the favourites to win the 2016 Major League Baseball World Series, however, the club is counting on its players being deep sleepers to get it there. As part of its league-leading analytics offerings, the Cubs recently added Fatigue Science’s wearable sleep monitoring technology to their performance management programs.

“Sleep and fatigue represent some of the most significant pieces of the human performance puzzle remaining,” says Mark O’Neal, Director of Medical Administration for the Cubs. “And even though there is an enormous amount of interest and discussion around these topics, sleep and fatigue are still very difficult to accurately monitor and measure. Fatigue Science changes that for us in a very real way, letting our coaches and athletes see where we can and should make adjustments to improve performance.”

Five of the Cubs’ minor league affiliate teams started the season wearing the Fatigue Science Readiband after successful Spring Training screenings and evaluations. “The results using Fatigue Science are very encouraging,” says O’Neal.

Fatigue Dashboard what impact is a lack of sleep favouring on your athletes performance

Originally designed for military and research communities to measure sleep effectively outside of the laboratory, Fatigue Science’s wearable technology is scientifically validated as the world’s most accurate wrist-worn sleep detection device.

Based on sleep quantity, quality and timing, Fatigue Science generates a real-time mental effectiveness score, as well as a predictive score that demonstrates mental effectiveness up to 18-hours in advance. If the score is low, an athlete’s reaction time, speed and strength is impaired. Alternatively, if the fatigue score is high, research proves that those well-rested athletes are faster, more accurate and make better decisions.

“All indications are that the entire Chicago Cubs organization is realizing the competitive advantages of effective fatigue monitoring and management,” says Fatigue Science CEO Sean Kerklaan. “We’re all looking forward to further demonstrating just how big an impact Fatigue Science can make on health and performance for the Cubs.”

Seattle Mariners first to bring Fatigue Science to Major League Baseball


The Seattle Mariners have joined the growing list of professional sports teams embracing sleep and fatigue analytics as part of their sports science program and the first in MLB to sign on with Fatigue Science.

“Major League Baseball teams are known for having some of the most gruelling game and travel schedules.” Fatigue Science co-founder, Pat Byrne says. “And West Coast teams in any league often suffer the most from the effects of time-zone changes when travelling for games. For this reason, we are really excited to bring the Mariners on board and show them how our technology can help find ways to measure and minimize the impact of both on their players.”

Fatigue Science technology can demonstrate the change in human reaction time throughout the day, based on circadian factors and historical sleep data. Past studies have shown that a player’s plate discipline, or their tendency to swing at the balls outside the strike zone, increases as fatigue sets in over the long MLB season. With such aggressive schedules and infrequent rest days, MLB teams often resign to accepting player fatigue as the season wears on but the Mariners are keen to see if they can change that. “Even with the schedule inflexibility that currently exists for these ball teams, if there is room for improvement, our technology will identify it.” Pat Byrne continues, “Anything to help get an edge.”

With pitches flying across the plate at 90 mph, even small improvements in reaction time could mean the difference between a swing and a miss, or the season’s game-winning play.
