这部2018年发布的纪录片，以Arnold Schwarznegger和一些素食运动员，例如UFC战斗机James James，超级马拉松运动员Scott Jurek和六次夺得一级方程式世界冠军的Lewis Hamilton为例子，赢得了一批忠实追随者的同时，也受到了一些批评。
Whether it be the influence of dieticians, sports scientists or foreign coaches and team mates, you only need to look at the physique of modern Premier League players to realise they take health and nutrition very seriously.
The game is faster and more demanding than ever and the competition for places means young players, in particular, are on the lookout for any ‘marginal gains’ they can make to improve their performance.
For some that now means giving up meat altogether and adopting a plant-based diet.
Norwich City’s 21-year-old full-back Caleb Richards has gone a step further by putting his experiences and thoughts on his diet into an e-book called ‘The Transition - an athlete’s guide to a meat-free diet’.
Richards, who was on loan at U.S team Tampa Bay Rowdies last year, was prompted to try to give up meat by the Netflix film “Game Changers”, which he watched in January.
The 2018 documentary, which features Arnold Schwarznegger and vegan athletes such as UFC fighter James Wilks, ultra marathon runner Scott Jurek and six-times Formula One world champion Lewis Hamilton, has won loyal followers but also received some criticism.
“It persuaded me slightly, but not enough to convince me that it genuinely worked,” said Richards, who nonetheless decided to experiment with such an approach.
The Salford-born player decided to try two weeks without meat and noticed immediate benefits.
“I saw results. My recorded top speed on my GPS unit at training, increased by 0.5 metres per second, which is huge when it comes to sprinting,” he said.
“That marginal gain alone had me convinced and feeling good about what more was to come. I was consistently having days feeling at my best and as confident as ever. Was this because of my new food choices, or was it coincidence? I didn’t know, but I was happy with how I felt and was willing to continue.”
