Good morning. A meta-analysis lands on lengthening work for hamstring returns, a dietitian explains the packet on every Chiefs pillow, and the Celtics add fifteen minutes of yoga off the plane. Let’s get into it...

A new review in Scientific Reports pooled 14 randomized trials and 693 athletes to find which hamstring strain rehab gets athletes back fastest. The clearest answer was lengthening-focused exercise, which loads the hamstring at long muscle lengths.
In two trials of elite soccer players and elite sprinters and jumpers, that approach returned athletes about 28 days sooner than conventional rehab. Re-injuries were 0 of 65 with lengthening and 3 of 66 with conventional rehab, a difference that wasn’t statistically significant. The authors rated the return-to-play evidence moderate certainty.
Two other findings: adding agility and trunk stabilization work didn’t speed up return, and rehab that allowed some pain (up to 4 out of 10) didn’t delay return and left athletes stronger. Most of the remaining evidence, including PRP, was rated low or very low certainty.
NUTRITION
🍒 The Packet on Every Chiefs Pillow

📸 Power Lift
According to a new Goal.com story, Leslie Bonci, the Chiefs’ lead dietitian, would leave a packet of tart cherry juice on each player’s pillow every night. Drinking it was mandatory. Players joked about cutting the taste with vodka. She wasn’t having it.
It isn’t just the Chiefs. The Steelers have used it, FC Cincinnati has it on the menu right after matches, and Liverpool’s Florian Wirtz was seen drinking it after a match in August. Tart cherries have antioxidant and anti-inflammatory properties and are a natural source of melatonin and tryptophan. “It’s routine at this point,” said Ally Maher, FC Cincinnati’s director of sports nutrition.
IN THE WEIGHT ROOM
🏀 Fifteen Minutes Right Off the Plane
The whole Boston Celtics roster did a group yoga session as part of this year’s camp routine, Payton Pritchard said via CLNS Media. The team used the hotel weight room. “It was a nice little 15 minutes, right off the plane,” he said, adding that it will probably become part of the routine.
It wasn’t mandatory before, so many players skipped it, including Pritchard. Yoga isn’t new to the franchise, though. Hall of Famer Robert Parish pioneered it in the NBA, and he has recalled being embarrassed at his first class when weekend athletes were touching their toes while he struggled to grab his shins.
COACHING
🎭 A Weight Room for Singers, Too
At Colorado Academy, the weight room isn’t just for athletes. Director of Sports Performance Isaiah Castilleja helped recruit fellow Elly Smith, who has a sports performance degree and music training, and she now works with the school’s performing arts teachers on fitness for singers, theater performers and dancers. Middle schoolers were also invited in for the first time this year.
