Dinu Godage, 11, says she used to hate everything about running.

Jade Glore, 12, says she used to think police officers were mean.

But the experiences the two Meyzeek Middle School students had while training to run 13.1 miles in tomorrow’s miniMarathon gave both of the girls new attitudes.

The two sixth graders are among the 16 Meyzeek students who will represent the Louisville Police Athletic League, known as PAL, in the Meijer Derby Festival miniMarathon.

The 22-member running club is made up of the students, as well as some of their parents and teachers who will be running in the race. The group has been training since November with help from PAL.

PAL is a nonprofit organization staffed by Louisville Metro Police officers. It works to improve the relationship between the community and the police.

“I always thought the police were kind of mean and serious,” Jade said. “They’re still serious but now they’re fun too.”

Creatine and glycerol hyperhydration in trained subjects before exercise in the heat.

Easton C, Turner S, Pitsiladis YP

Int J Sport Nutr Exerc Metab. 2007 Feb ; 17(1): 70-91

The authors examined the effects of combined creatine (Cr) and glycerol (Gly) supplementation on responses to exercise in the heat. Subjects (N = 24) were matched for body mass and assigned to either a Cr or placebo (Pl) group.

Twice daily during two 7-d supplementation regimens, the Cr group received 11.4 g of Cr.H2O and the Pl group received 11.4 g of glucose. Subjects in both groups also ingested 1 g of Gly/kg body mass (twice daily) in either the first or the second supplementation regimen.

This design allowed 4 possible combinations of supplements to be examined (Pl/Pl, Pl/Gly, Cr/Pl, and Cr/Gly). Exercise trials were conducted pre- and postsupplementation at 30 degrees C and 70% relative humidity. In the Pl group, total body water (TBW) increased by 0.50 +/- 0.28 L after Gly and in the Cr group by 0.63 +/- 0.33 L after Pl and by 0.87 +/- 0.21 L after Gly. Both Cr/Pl and Cr/Gly resulted in significantly attenuated heart rate, rectal temperature, and perceived effort during exercise, although no regimen had any effect on performance. The addition of Gly to Cr significantly increased TBW more than Cr alone (P = 0.02) but did not further enhance the attenuation in HR, Tre, and RPE during exercise.

These data suggest that combined Cr and Gly is an effective method of hyperhydration capable of reducing thermal and cardiovascular responses.

Thermic and glycemic responses to bread and pasta meals with and without prior low-intensity exercise.

Warwick PM

Int J Sport Nutr Exerc Metab. 2007 Feb ; 17(1): 1-13

The purpose of the study was to investigate thermic and glycemic responses to conventional meals with and without prior low-intensity exercise. Fourteen healthy volunteers (7 men, 7 women) undertook 4 treatments, 2 bread and 2 pasta meals, either with (E) or without (NE) prior exercise (a 45-min treadmill walk). Meals provided 58 g carbohydrate and 2360 kJ. Energy expenditure and blood-glucose concentrations were measured before and for 3 h after the meals. The thermic effect of food (TEF) was lower after pasta (121 +/- 32 kJ/3 h) than after bread (154 +/- 62 kJ/3 h), P = 0.009, but was not affected by exercise. Glycemic responses were lower after E (155 +/- 113 mmol.L-1.3 h-1) than NE (199 +/- 97 mmol.L-1.3 h-1) after pasta (P = 0.020) but not after bread. TEF was lower after pasta than bread but was not affected by prior low-intensity exercise. The effects of exercise on glycemic responses to meals were inconsistent.

I ran a mile!

Yay! I felt ok for the most part. I had a couple stretches where I had some pain in my shins, but I also think that when I was out running I was payin way too much attention to my shin splints. I mean if I am sitting here now, I can try and feel pain in my scalp if I want to. Walking around today I felt no pain after my run. Perhaps I am almost done with these shin splint bastards. We’ll see tommrow when I try two miles! gasp!
