Stakeholders, stakeholder roles and exemplary quotes on the theme ‘everyone has a role to play in the team’

Stakeholder	Stakeholder roles	Exemplary quotes
Head coach	Decision making Authority Leadership Communication	PH3: “Some coaches they accept, they accept what we say (…) So, we prevent the injury. You have the other ones they don’t want. No. So, when the injury happens, they understand, but we lose the player.” HC3: “It is the coach (…) I wouldn’t say he is the most important person, but he is the leader. He is important, but I think, in my opinion, he can create a very positive atmosphere and communicate. If we go back to big names, big coaches, they don’t have this common style anymore. They are open. They have 3 or 4 assistants. They talk to the medical staff, and it is very rare when we hear a big coach having a problem with the medical staff because they are open-minded, they listen to them, they listen to you.” PH1: “First is the coach, the head coach. Because right now he is the boss, he even interferes on the timing of the lunch and breakfast.” FC1: “With others (head coaches), no, they do whatever they want. If the team loses, they are fired, so they have to decide and help to make a decision. Some coaches listen more. Some listen less.” HC1: “I know the situation is not so easy because here people demand you to win, and then, you would need your best players. Maybe the player is not ready, so injury prevention is also impacting my decision-making.”
Team doctor	Diagnosis Treatment Supervision	HC1: “The physios and the doctor, if the player gets injured, they are kind of the bosses until he (player) is ready to come back to training with us. So, we are preventing this guy from being re-injured.” FC3: “the doctor makes the diagnosis, and then after that, he makes the treatment with the physio.” “We have the doctor who is the one in charge to supervise them [physiotherapists).” PH4: “Ok, for the doctor, he can give the supplementation, plus establishing diagnosis if something is alarming.” TD4: “We, I mean doctors, physiotherapists, nutritionists, nurses, physiologists, we are in the team to support the coach to make them perform.”
Physiotherapist	Screening Preventive exercises Cooperation with fitness coach	PH4: “If he [player] has a deficiency in some muscle or some part of his body, we try to help him to strengthen and correct it. So, our role is the correction of their weaknesses.” FC1: “Mm oh, for example, we arrived in July we made the screening, so the physios sent me a report giving me that this guy is having a weakness in adductor or a poor control in whatever.” FC3: “Their role [medical staff as a whole] is to treat the players. Treat the players and to also make the injury prevention program inside the medical staff and also to bring them to the field, to the exercise related to the game, related to the training session to be sure they are ready to come for real.” PH2: “I also need to see what the fitness coach is giving because I can give some prevention and the physical coach is also giving other prevention, so I need to balance if I feel that the player is getting a good dose from certain exercise. Then I need to look for other exercises that the physical coach is not giving him. For example, the physical coach is giving more concentric I will advise the player to do some eccentric, some dynamic stretching.” PH1: “With the fitness coach, because we have to know the load of the training to know what kind of exercise we need to implement, we can implement balance exercises for improving proception and coordination before hard training, but we cannot implement strengthening eccentric work before hard training.”
Fitness coach	Communication bridge Health & fitness of fit players	FC2: “…this is our part; it is the monitoring of the load and the health in general. Health in general, not only fitness.” FC3: “Because I see sometimes, I come, and I don’t make injury prevention program, I decide not to do anything for the muscles (…) For me, every day it is load …load…load. So be careful because if you put the load, too much load, you have to manage. This is my advice.” PH4: “…the physical coach is very well managing the load, so your work will become easier because the recovery will be easier, the injuries will be less, the risk will be less.” HC1: “…I use the fitness coaches to be the guy in communication with the medical team. Because their expertise lies here and also here, (…) so the communication for me if the player is complaining, this problem goes more to fitness coach than to medical team. So, this is, I think, because the communication is better through this channel.” PH1: “The link is the fitness coach. We have to talk to the fitness coach, and he transfers to the coach. Then it is vice versa and from the coach to us, medical staff.” TD1: “For example, in the club, the communication is better through the fitness coach that you already met, [name fitness coach] Before it was direct with the coach. (…) I prefer discussing with the coach. Because he is the person to decide.”
Player	Acceptance Compliance Education	PH2: “I think the player should also be involved. They need to know that they are a major factor in the injury if they don’t rest well, if they don’t recover well, if they don’t give good intensity in training, then they are compromising their performance and their level, their competition. Yes, this is a very important factor.” PH1: “Because since 2011, I tried to do many things, but the player didn’t follow us, you know?! About lifestyle: when they eat, when they have to sleep, their recovery. Because, no, it’s not that we don’t talk, we talked with that to the players. (…) they say we agree. We will do that. Then, after one week when we ask again: what did you do? How was it? They have the same lifestyle as before, especially the local players.” HC2: “Education for prevention, I think it is important that the players understand ‘’the why’’. This is very much necessary, …” TD2: “The most important thing: the players are aware of this (…) the players accept it (…) they accept because they are aware. I think they have the knowledge or the… I think all the system is centralized with Aspetar and Aspire; I think they have this knowledge about prevention.”
General manager	Budget Resources	TD1: “Managers, because they give money, they can influence the decision making; try to communicate with the coach sometimes and also with the player.”
