The anti-doping campaigner behind the controversial tweeted video of Chris Froome has called on Team Sky to release the Briton’s power data to dispel any doubts about his probity, and has broadened the call to include all cycling teams.

“I’d like Sky to publish all that, to restore credibility,” said Antoine Vayer, the Breton teacher who passed on what is alleged to be Froome’s data to the person who compiled the video marrying what purported to be Froome’s power-meter and pulse data with television footage of the Tour de France leader on Mont Ventoux in 2013.

On Wednesday a second video was released, showing similar data but this time of Froome in the 2014 Vuelta.

“We need transparency because no one believes in cycling any more and this is a sport with super, good people in it,” said Vayer. “So many things in cycling were hidden over the years that the only solution is to lay ourselves bare.

“To make people believe we need to be transparent, we need to interest spectators in other information than just personal stuff about the cyclists – they have a nice family, they come from somewhere interesting. We need data. We need to publish cyclists’ blood-test results.”

Froome has insisted he has done all he can to prove he is a clean rider, even volunteering to undergo independent physiological testing after the Tour finishes.

“What haven’t I done? I’ve tried to be as much a spokesman as I can for clean cycling,” Froome said. “I’ve spoken to the CIRC [Cycling Independent Reform Condition], I’ve made suggestions to the governing body to implement things like night-time testing. I’ve pointed out when I’ve felt there hasn’t been enough testing, in places like Tenerife. What else is a clean rider supposed to do?”

Sky have had requests for transparency over data before but have turned them down on the grounds that if released into the public domain, heart-rate, power and cadence figures are open to misinterpretation by non-experts.

There is much speculation over power output figures and power-to-weight ratios, in particular on internet sites, with claims and counter-claims over whether some of them are physiologically possible. Vayer also claimed he proposed to the Tour de France organisers ASO in 1999 that they should display data from all the peloton but the suggestion went nowhere.

Speaking to the Guardian, Vayer said he had received what he believes to be Froome’s data from 2013 on Mont Ventoux through a leak rather than through computer hacking. “Someone sent it to me, I don’t know who it came from. I thought it was fake.” Examination of the data and cross-referencing with Froome’s cadence and speed from the television footage led him to believe they were genuine, however, as did the low heart-rate values which he felt were possibly unique to Froome.

“When I saw the heart rate I said it must be correct. I knew Chris Froome had a low heart rate, his former trainer at the UCI centre in Aigle told me.” There was other data from other races, he said, including last year’s Tour of Spain, but it was not as accurate. Vayer insists he did not put the data online: “It was one of my [Twitter] followers.”

Froome said on Tuesday the low heart rate on display on the video is normal for him. “I’ve put that part of the data out there myself in my book. My maximum heart rate is only at about 170. After two weeks of a Grand Tour I’m quite surprised it went as high as 160. Normally it’s a bit lower than that sometimes. It’s normal once I get two weeks into a Grand Tour, 10 beats off my maximum when I’m going as hard as I can.”

Vayer, a former trainer at the Festina team, says the video is “a way to undress the secrets”. He gives short shrift to the idea that – assuming the data is genuine, as he clearly believes – he is involved in a breach of confidentiality using information from an uncertain source which has been obtained without consent.

“Having ethical lessons from within cycling is a very funny thing.” The end of transparency, he feels, justifies the means. It could reasonably be argued Vayer is stoking the fire with his writing in which terms such as superhuman and miraculous are wielded with sceptical abandon, as are claims such as, from 2013, “Froome was clocked at 418 watts” when climbing Mont Ventoux.

However, in a more reflective article in Le Monde in 2013, after a long meeting with the Team Sky principal, Sir Dave Brailsford, and the Sky trainer Tim Kerrison to clear the air, Vayer made essentially the same call for clarity that he is making now.

“I have nothing against Dave Brailsford. It was an important meeting for me. I said, ‘Dave, I like you, but explain to me how is it possible?’ There is a huge confusion among cycling watchers, there are lots of questions. I asked if Chris had done tests, VO2 max [the maximum volume of oxygen that an athlete can use] etc, and he said, ‘No, none of that’. It’s a pity because if [Froome] came to my lab and did a VO2 max and had a value of 90, you could just say he is exceptional. You can see from the video he is exceptional.

“ I’m not doing this in an aggressive way. I’m not doing it to make a buzz, I’m not doing it to say they are all doped. It’s for transparency. I’m not aggressive about it, just fed up of going to drink a coffee in a cafe in Brittany and having everyone mock cycling. I don’t want champions to be mocked, derided. Everyone asks if they are clean, if I say yes, they laugh and say prove it. To say riders are clean, you need the data,” he wrote.
