Abstract: most soccer matches are conducted by coaches who usually make all player substitutions allowed. therefore, it is extremely important to study these substitutions and their effects on the intensity of effort required from players. to date, no published studies have reported on this topic using heart rate (hr) as an intensity parameter. the objective of this study was to compare effort intensity (ei) of soccer players in the following situations: 1) first half (fh-ei); 2) second half (sh-ei); 3) second half with substitutions (shs-ei). forty-five male soccer players (18.5±1.2 years old, 74.25±5.79 kg, 182.6±8.55 cm, 9.56±2.47% body fat, 56.3±4.3 mlo2/kg/min) were evaluated during 29 official games. ei was considered as the mean hr, expressed as the percentage of each player's maximal hr (%hrmax) and as the time spent in each intensity zone (z) according to %hrmax (z1<70%; z2 70-85%; z3 85-90%; z4 90-95%; z5 95-100%). fh-ei (86.3±3.3%hrmax) was higher than sh-ei (80.6±4.4%hrmax) and shs-ei (83.6±2.8%hrmax). shs-ei was higher than sh-ei (p<0.05). time spent in high-intensity zones was lower in sh-ei than in fh-ei, but higher in shs-ei when compared to sh-ei (p<0.05). it was concluded that the decrease in ei in the second half of soccer matches was attenuated by substitutions made at halftime, as evidenced by a longer time spent in high-intensity zones when compared to sh-ei.

Abstract: Endophytic bacteria may influence agricultural production in several ways, including promoting plant growth. Two experiments were conducted in order to evaluate the combination of endophytic bacteria from the Brazilian Northeast region aims at the commercial introduction of the inoculation of these bacteria in micropropagated sugarcane plants using a temporary immersion bioreactor. One experiment was done in tubes with sterile commercial substrate, and the other was done in pots with soil; both were installed in a greenhouse. A mixed inoculation was performed in six inoculated endophytic diazotrophic bacteria in micropropagated sugarcane plants, variety RB92579. In the experiment with soil, the mixed inoculation significantly increased the shoot dry matter of plants without the addition of nitrogen fertilizer. However, the accumulation of total-N in the tissues showed no significant differences between treatments with and without nitrogen fertilization. The evaluation of micropropagated seedlings showed no increases in the parameters tested. The results showed that the response of inoculation in temporary immersion bioreactor micropropagation is possible, and that the application of homologous strains may have contributed to a better response by the interaction of endophytic bacteria with sugarcane RB92579. Further studies should be conducted to improve the methodology, which indicates a great potential to optimize this process on a commercial scale.
