This study shows that NBA Players Who Use Twitter Late At Night Played Worse The Next Day

Professional athletes seem to be using Twitter….. Well.. All the time. And this study shows that NBA players actually performed worse after a late-night of Tweeting.

According to Sports Illustrated, researchers at Stony Brook studied basketball players they found on social media the night before a game and then studied how they performed compared to nights when they were apparently not logged on.

Stony Brook’s research is the first of its kind to present time-dependent findings, providing the clearest evidence of a performance penalty following nocturnal tweeting activity, between 11:00 p.m. and 7:00 a.m. local time.

The study analyzed 112 players’ tweets from 2009-2016, filtering 581,190 posts into a dataset of 37,073 late-night messages.

After scraping in-game statistics from Yahoo Sports’ website, Stony Brook’s evaluation determined players score 1.14 fewer points and play 2 fewer minutes in games following late-night tweeting, as opposed to games not following late-night tweeting.

The biggest effect appears in shooting efficiency. On average, the 112 players shooting percentages tickets 1.7% points lower in games following late-night Twitter activity, a decline from 45.35% to 43.65%.

Even worse, when players tweeted between the hours of 2 a.m. and 6 a.m., shooting success rate dropped a staggering 3.6% overall.

The shooting drop off even extends to 3.95% for players late-night tweeting on the road. Many teams have instituted evening guidelines for their players while they’re cooped up in a random hotel in a random city, often unsure of what day or time zone they’re currently in. “We have protocols in place,” Nets head coach Kenny Atkinson said. “I think it’s important and I think it’s gonna become more important. We talk about it. We present tips to our players.”

Players like Clippers point guard Patrick Beverley balked at the correlation. “Hey man, next thing you know, if you don’t jump over a cat three days before the game, you ain’t gonna make two layups,” he said. Yet if all 11 players who played for the Clippers against the Nets shot 1.7% worse from the field, Los Angeles would have collectively converted two fewer baskets—the Clippers shot 48-95 from the field—and assuredly seen its eight-point, come-from-behind win become that much more of a nail-biter. “If two or three players are sleep deprived, that adds up,” He said.
