Eat carbs before a run?
You might hear that before a big race or game, it’s wise to load up on carbs to make sure you have enough energy to get you through it.
But, it turns out, pre-exercise meals that are higher in protein or fat may also make good choices.
That’s the focus of a new paper by Florida State University Assistant Professor Michael Ormsbee and his Human Performance and Sports Nutrition Lab. Ormsbee was invited to write a paper reviewing the current research on pre-activity nutrition for a special “Sports Nutrition” issue in the journal Nutrients.
Though carbs do work, there’s been no significant research on other food groups to compare and contrast effectiveness.
“Carbs have been the focus for endurance runners but some new research and some anecdotal evidence suggests that higher fat diets may actually work before exercise to improve metabolism and possibly health and performance,” Ormsbee said.
And that will help set the tone for some of Ormsbee’s research moving forward. Ormsbee said the lab is launching a number of upcoming studies to investigate performance, health and body composition advantages to different foods and supplements for both endurance and strength athletes.
Ormsbee and doctoral students Dan Baur and Chris Bach examined research that had been the standard for the past few decades in sports nutrition.
Baur said there was plenty of information available extolling the virtues of protein consumption post workout, but when it came to pre workout fuel, the information dried up.
“Everything you read right now is saying protein is good, but they’ve never taken a deep look at how it can affect your body before a workout or competition,” Baur said. “The main finding was that more research is needed.”
Added Bach: “There are a lot of preconceived notions and also there’s some anecdotal evidence. For the most part, the work that we’re getting into is really exciting stuff because it’s a new frontier in the world of sports performance.”

The ACL knee injury epidemic that no one is talking, or doing anything, about
Female athletes who play basketball and soccer are two-to-eight times more likely to suffer an ACL injury compared to male athletes, according to the American Orthopaedic Society for Sports Medicine.
The epidemic is getting worse as more females play sports, said orthopaedic surgeon Dr. Pietro Tonino, director of Sports Medicine at Loyola. And summer is among the peak times for injuries because many females are playing soccer and other sports.
“I’m tired of seeing so many girls and young women with ACL injuries in my clinic,” Tonino said. “Many of these injuries could be prevented with a simple warm-up program that can be done in minutes.”
Tonino said one such program is FIFA 11+, a warm-up program designed to reduce injuries among male and female soccer players. The program should be performed, as a standard warm-up, at the start of each training session at least twice a week. It takes about 20 minutes. Teams that perform FIFA 11+ at least twice a week experience 30 percent to 50 percent fewer injured players, according to FIFA, the governing body of the World Cup and other international soccer tournaments.
The anterior cruciate ligament, or ACL, is one of the four major ligaments of the knee. It connects the front of the tibia (shinbone) with the back of the femur (thighbone). It helps provide stability to the knee joint. Patients with torn ACLs often experience their knee “giving out.” ACL injuries also increase the risk of arthritis.
Tonino has performed thousands of surgeries to repair ACL tears. “We can get athletes back on the field or the court, and they can perform at very high levels,” Tonino said. “But a reconstructed knee can never be as good as a God-given knee. So athletes, coaches and parents should do everything possible to prevent ACL injuries. Spending a few minutes on injury-prevention exercises at the beginning of practice can benefit an athlete for the rest of his or her life.”
Tonino is a professor in the Department of Orthopaedic Surgery and Rehabilitation of Loyola University Chicago Stritch School of Medicine.
It’s what you eat, not how much you work out: newest clinical weight-loss evidence

Sucrose compared with artificial sweeteners: a clinical intervention study of effects on energy intake, appetite, and energy expenditure after 10 wk of supplementation in overweight subjects 1,2,3 Lone B Sørensen, Tatjana H Vasilaras, Arne Astrup, and Anne Raben First published April 30, 2014, doi: 10.3945/ajcn.113.081554 Am J Clin Nutr June 2014 ajcn.081554 + Author Affiliations 1From the Department of Nutrition, Exercise and Sports, Faculty of Science, University of Copenhagen, Copenhagen, Denmark. + Author Notes ↵2 Supported by The Danish Research Councils, FØTEK (Development Programme for Food Technology), Danisco Sugar (unrestricted grant), and Coca Cola (Nordic and Eurasia Divisions) (unrestricted grant). ↵3 Address correspondence to LB Sørensen, Department of Nutrition, Exercise and Sports, Faculty of Science, University of Copenhagen, Rolighedsvej 26, DK-1958 Frederiksberg C, Denmark.

Abstract
Background: There is a lack of appetite studies in free-living subjects supplying the habitual diet with either sucrose or artificially sweetened beverages and foods. Furthermore, the focus of artificial sweeteners has only been on the energy intake (EI) side of the energy-balance equation. The data are from a subgroup from a 10-wk study, which was previously published.
Objective: The objective was to investigate changes in EI and energy expenditure (EE) as possible reasons for the changes in body weight during 10 wk of supplementation of either sucrose or artificial sweeteners in overweight subjects.
Design: Supplements of sucrose-sweetened beverages and foods (2 g/kg body weight; n = 12) or similar amounts containing artificial sweeteners (n = 10) were given single-blind in a 10-wk parallel design. Beverages accounted for 80% and solid foods for 20% by weight of the supplements. The rest of the diet was free choice. Indirect 24-h whole-body calorimetry was performed at weeks 0 and 10. At week 0 the diet was a weight-maintaining standardized diet. At week 10 the diet consisted of the supplements and ad libitum choice of foods. Visual analog scales were used to record appetite.
Results: Body weight increased in the sucrose group and decreased in the sweetener group during the intervention. The sucrose group had a 3.3-MJ higher EI but felt less full and had higher ratings of prospective food consumption than did the sweetener group at week 10. Basal metabolic rate was increased in the sucrose group, whereas 24-h EE was increased in both groups at week 10. Energy balance in the sucrose group was more positive than in the sweetener group at the stay at week 10.
Conclusion: The changes in body weight in the 2 groups during the 10-wk intervention seem to be attributable to changes in EI rather than to changes in EE. Source
