In order to get around these various different obstacles in the way of the development of sports activities in prison, it would be appropriate to everywhere plan access to an independent sports area from exercise areas, enabling the practice of physical exercise and collective sports. Only organised sports activities and events organised with external teams would still use the centre’s sports ground. More generally, in view of the majority of young people composing their population, prisons and young offenders’ institutions should moreover include premises promoting the practice of physical and sports activities. The available facilities should cover both individual (weight training in prison) and collective needs, in covered (gymnasium, multipurpose room etc.) and open air premises. b) The dimensions of the structures, the design of the buildings and the resulting positioning of staff have a considerable effect upon the operation of services. Although psychiatric treatment units and young offenders’ institutions are characterised by supervision in close relation with the person, the same does not apply in prisons – with the probable exception of those of dimensions of less than 100 places – in which staff and actors find themselves at a distance with regard to the day-to-day life of prisoners, this distance sometimes even meaning that the latter never go to the accommodation wings. In certain institutions, individual interview rooms exist in the prison but are never used, in particular by the CPIP, or even by managerial staff. Loss of time, connected in particular to the numerous hold-ups of movement during the day due to the beginning and end of exercise periods, constitutes the grounds most commonly mentioned in order to justify interviews being held outside of the accommodation sector, without taking the fact into account that, for the same reasons and at the same times, prisoners have the same difficulties in leaving the prison area… On the other hand, the slowness of movements, the waiting times at the numerous intermediate bars and the various different locations of people to be seen in different wings are legitimate arguments. Nevertheless, the distance generated between staff and prisoners deprives the latter of an institutional presence in (or even control of) their daily environment. In other institutions, in view of the number of actors230 as compared with the number of offices, the latter are sometimes occupied by other persons and therefore unavailable. For this reason, the wings should have a sufficient number of interview premises and make provision for waiting rooms accordingly. These offices should be easily accessible (both by themselves and by persons deprived of liberty and their families, with the objective of optimisation of working time), of appropriate size for their intended use and ensure the confidentiality of exchanges. Provision should also be made for meeting rooms promoting encounters between the various different actors in order that supervision of the persons concerned can be really multidisciplinary and concerted, including in partnership with them. It should also be possible for institutional meetings to be held there, in particular in order to enable prisoners to take part. 230 Youth workers, doctors, teachers from the national education system, prison rehabilitation and probation counsellors (CPIP), members of legal information and advice access points (PAD), lawyers, staff of welfare bodies, representatives of the Défenseur des droits ombudsman, chaplains, prison visitors etc. 151
