Physical exercise is recommended to maintain the muscular mass in elderlies (Singh, 2002). Among the different types of exercise programs, there is the multicomponent training (Carvalho et al., 2010). The multicomponent training program allows the subjects to improve their physical condition (Strength, resistance, flexibility and balance) (Carvalho et al., 2009). However, there is no consensus about the influence of multicomponent training in body composition. Thus, the aim of this study was to access the multicomponent training effect in elderly's body composition. The sample of this study was composed of forty nine 64.39 (± 6.33) year-old elderlies. Among them, 11 were 67.45 (± 4.93) year-old males and 38 were 63.50 (± 7.47) year-old females. All procedures carried out in this research were in accordance to the Declaration of Helsinki. A multicomponent training program was applied with the Carvalho et al, (2009). The program took 8 months and the training frequency was three times per week. The elderly's body composition were assessed with bio-impedance (Tanita, BC-545). The T-test allowed to assess the differences between the pre and post training program in the body composition. The tests were performed with a significant level of 5%. A multicomponent training program in elderlies seems to influence the body composition. The total body mass decreased between the two moments. The bone mineral mass and body water percentage had a significant increase between the two moments. Even more, all the variables improved between the two moments. ; This project was supported by the National Funds through FCT - Portuguese Foundation for Science and Technology (UID/DTP/0445/2013) and the European Fund for regional development (FEDER? allocated by European Union through the COMPETE 2020 Programme (POCI-01-0145-FEDER-006969) ; info:eu-repo/semantics/publishedVersion

Elderly's physical activity and exercise is a huge concern in fitness instruction to delay physical frailty (Jones & Rikli, 2002). The multicomponent training helps to improve the physical condition in different variables such as strength, resistance, flexibility and balance (Carvalho et al., 2009). Thus, the aim of this study was to assess the influence of an eight months multicomponent training program in functional fitness of community-living elderlies. Forty-nine 64.39 (± 6.33) year old elderlies took part of this research, 11 males who were 67.45 (± 4.93) and 38 females who were 63.50 (± 7.47) years old. All procedures were in accordance to the Declaration of Helsinki and a written consent was obtained from the participants. The multicomponent training program was applied with the Carvalho et al, (2009) recommendations. It was a 8 months program and the training frequency was three times per week. The elderly's functional fitness was assessed with the functional fitness test (FFT) of Jones & Rikli, (2002). The T-test allowed to assess the differences between the pre and post training program in the body composition. The tests were performed with a significant level of 5%. The multicomponent training program improved significantly the elderly's functional fitness in upper and lower limbs strength. The other variables didn't present significant improvements with the multicomponent training program, however, it is worth noting that everyone improved their scores. Thus, it is possible to conclude that the multicomponent training program may improve and/or preserve elderlies' functional fitness. ; This project was supported by the National Funds through FCT - Portuguese Foundation for Science and Technology (UID/DTP/0445/2013) and the European Fund for regional development (FEDER? allocated by European Union through the COMPETE 2020 Programme (POCI-01-0145-FEDER-006969) ; info:eu-repo/semantics/publishedVersion

The labour risks control is an occupational health concern. Fitness participants have been increasing in the last years (Lindwall, 2004). Clients' demand and the increase in classes number take the fitness instructors (FI) to a higher injuries exposure due to high workload. It is possible to observe several variations in aerobic dance, cycling, pilates, strength training, flexibility and balance. The main differences are in the cardiovascular intensities and the low to high impact dance (Van Mechelen, Hlobil & Kemper, 1992). The FI are exposed to high volumes of classes and injuries risks due to the high number of students and classes (Couto et al., 2016). As far as our understanding goes, FI are 50% more prone to injuries incidence in comparison to students. Thus, the aim of this study was to assess by a bibliographic research the health and injuries risk in FI. This is a bibliographic review made in PUBMED, Google Scholar, SCIELO and Web of Science. The used keywords were "fitness instructors injuries", "fitness professor's injuries", and "fitness instructor's risks". From an analysis of 23 papers, ten were chosen considering title and abstract. After a full integral analysis, only five papers were selected for revision. The others did not aimed to analyse the injuries and the health risks for FI. The selected papers approached the injuries and health risk factors for FI. There is a positive and significant correlation between the formation levels and injuries incidence prevention in FI and students (Malek, Nalbone, Berger & Coburn, 2002). FI with higher classification prevent higher frequency of injuries events. The injuries prevalence was superior in FI than in students (72.4 – 75.9% and 22.8 – 43.3% respectively) (Mutoh, Sawai, Takanashi & Skurko, 1998; Francis, Francis & Welshons-Smith, 1985). The injuries were general inflammations, muscle strains or sprains and stress fractures by overuse (Rothenberger, Chang & Cable, 1988). The FI are more exposed to injuries than students are (0.17 injuries/100h vs 0.15/100h of practice, respectively) and about 77% of the injuries were in the lower limbs (Garrick, Gillien & Whiteside, 1986). There is a lack of research in FI injuries risk of factors. However, FI seem to have a higher exposure to injuries in comparison to students. The high workload seem to be determinant to the incidence of overuse injuries. ; This project was supported by the National Funds through FCT - Portuguese Foundation for Science and Technology (UID/DTP/0445/2013) and the European Fund for regional development (FEDER? allocated by European Union through the COMPETE 2020 Programme (POCI-01-0145-FEDER-006969) ; info:eu-repo/semantics/publishedVersion
