The concentration of beta-endorphin (B-EP) was measured in 12 male recreational runners before and after marathon running. All subjects could finish 42 km distance and their mean time for finishing was 3 hr and 50 min (3 hr 6 min - 4 hr 22 min). Plasma B-EP significantly (P<0.0001) increased to about 9.8-fold above base line, from 9.1 ± 0.8 (SE) to 88.9±17.0 pg/ml. In addition, B-EP remained above baseline at 30 min and 60 min after the marathon race (43.9 + 12.7 pg/ml; P<0.0001 and 33.6± 6.6 pg/ml; P<0.001, respectively) and dropped to baseline 24 hr following the race. Lactate concentration also significantly (P<0.0001) increased during the marathon race (from 11.8±0.12 to 2.33± 0.18 mmol/L). This value was far below anaerobic threshold levels, 4 mmol/L, and was equivalent to approximately 60-65% VO_2max of our subjects. Previous studies have reported that the peripheral B-EP responses may be intensity dependent and that an exercise intensity of at least 70% VO_2max for 15 min is needed to increase plasma B-EP. Since our subjects performed extremely over-duration exercise and were exhausted after the race, therefore, the undue physical stress might affect the increase in B-EP. In conclusion, plasma B-EP responses may be both intensity and duration dependent.

Theory and Practice of Language Teaching This paper discusses the tension exerted between the linguistic hybridity movement (LH) and linguistic imperialism (LI). The current literature on LH and LI clearly demonstrates a passionate debate between the two linguistic schools of thought. The succinct difference between the LH movement and LI is distinguished between the LI approach, which adopts a deterministic, monolithic approach to language, while the LH movement adopts a relativistic, apathetic approach.
