Estudo dos efeitos da restrição alimentar nas características das fibras musculares de bovinos jovens confinados

The influence of restricting feed intake of young bulls in feedlots was evaluated in terms of structure of muscular fibers and respective areas, sampled by biopsy on the semitendinoso muscle. Sixty six crossbred Simental-Nelore bulls, 8 months old, averaging 220±34.03 kg were submited for 84 days in phase 1 (growing period), to three treatments: ad libitum (AL), restriction + whole soybean (RWS) and restriction + toasted whole soybean (RTS). The level of restriction of feed intake was 23%. Phase 2 was performed by splitting the animals in each treatment in phase 1 in two groups, feeding one with a diet containing soybeans and the other with poultry litter. The results showed that the animals AL presented more white fibers (FG), compared to the RWS and RST and a larger area of these fibers. A greater frequency of red fibers was observed in treatments RWS and RST. The conclusion was that the restriction of feed intake and consequent compensatory growth contributed for modulation of the muscular fibers increasing the frequency of the fast oxidative glycolitic (FOG) in 10.88% and decreasing of the slow oxidative (SO) and FG in 4.81 and 6.90%, respectively, with possible alteration on meat quality.

Coping strategies among brazilian professional and amateur football players

To identify coping strategies used among professional and amateur Brazilian football players. The Ways of Coping Scale (WOCS) was completed by 134 male football players (71 professionals: mean age = 22.77 ± 3.98 years; 63 amateurs: mean age = 17.18 ± 0.84 years) from three teams that participated in the Campeonatos Estaduais da Primeira Divisão (the state championships for the first division of football). There was no significant difference between the two groups in the type of coping strategy they used (e.g., problem-focused, emotion-focused, fantasy thoughts, religious practices and social support). Problem-focused coping was the most frequently used strategy by all of the players and social support was the least frequently used strategy. Both professional and amateur players failed to focus on the development of adequate coping strategies. Further studies are needed to better understand the impact that Brazilian athletes experience has on their choice of coping strategies during pre-competitive and competitive phases of their sport. © JPES.
