Improved recovery from prolonged exercise following the consumption of low glycemic index carbohydrate meals

The present study examined the effects of the glycemic index (GI) of post-exercise carbohydrate (CHO) intake on endurance capacity and the metabolic responses during exercise the following day. Nine active males participated in two trials in a randomised crossover design. The experimental protocol was completed over two days. On day 1, subjects completed a 90 min treadmill run at 70% VO2 max (R1). Thereafter, they were supplied with a diet consisting of either high glycemic index (HGI) or low glycemic index (LGI) CHO and provided 8g CHOkg body mass (BM)-1.On day 2, after an overnight fast, subjects ran to exhaustion at 70% VO2 max (R2). Eight subjects completed both performance runs (R2). Run time to exhaustion during R2 was longer in the LGI trial (108.9 7.4 min) than in the HGI trial (96.9 4.8 min) (p<0.05). Average RER values were higher in the HGI trial compared to the LGI trial (p<0.05). Fat oxidation rates and free fatty acid concentrations were higher in the LGI trial than the HGI trial (p<0.05). The results of the study suggest that the increased endurance capacity during R2 was largely a consequence of the greater fat oxidation following the consumption of the LGI meals

Technique for Evaluating the Erosive Properties of Ablative Internal Insulation Materials

A technique for determining the average erosion rate versus Mach number of candidate internal insulation materials was developed for flight motor applications in 12 inch I.D. test firing hardware. The method involved the precision mounting of a mechanical measuring tool within a conical test cartridge fabricated from either a single insulation material or two non-identical materials each of which constituted one half of the test cartridge cone. Comparison of the internal radii measured at nine longitudinal locations and between eight to thirty two azimuths, depending on the regularity of the erosion pattern before and after test firing, permitted calculation of the average erosion rate and Mach number. Systematic criteria were established for identifying erosion anomalies such as the formation of localized ridges and for excluding such anomalies from the calculations. The method is discussed and results presented for several asbestos-free materials developed in-house for the internal motor case insulation in solid propellant rocket motors

Liberalization, privatization, and crash: Mexico's banking system in the 1990's

Although Mexico's 1994 peso devaluation and subsequent capital outflows shook the nation's banking system, the foundations of the banking crisis were laid much earlier. ; Econometric evidence suggests that in the wake of the 1991-92 bank privatizations, Mexico's banks entered a market share struggle in which they incurred short-term losses at the margin, perhaps in the interests of greater expected gains over the long term. ; Euphoric investor behavior and a rising economy may have aggravated the situation by making risky borrowers more difficult to identify.Mexico ; Devaluation of currency ; Peso, Mexican
