Cutting-Edge Research: Chocolate Milk for Tournaments?

After an intense match, muscle glycogen and blood glucose levels may be very low. That is, athletes may be very low on energy. The only way to refuel the system, so to speak, is through the diet or post-game meal. During a tournament, when two matches are played on the same day, players need to have a nutritional strategy to prepare themselves for the second match of the day - what to eat and drink between matches. In a study just released by the journal Applied Physiology, Nutrition and Metabolism, investigators from Northumbria University found that chocolate milk might be an ideal recovery drink.

The study examined the effects of three drinks on recovery and performance, chocolate milk (2%), Gatorade and Endurox. The subjects first exercised on a stationary bicycle for ~65 minutes, alternating 2 min intervals of pedaling at 75% and 50% of their max. This bout of exercise was designed to deplete the muscles of glycogen. They were allowed to recovery for four hours after which they rode at 70% of their max for as long as possible. During the recovery they drank one of the three beverages. Part was consumed immediately after exercise and the rest 2 hours later (~500ml or 1 pint total).

The investigators found that when the subjects drink chocolate milk during the 4 hour recovery period, they able to exercise longer considerably during the endurance trial (32 min versus 23 and 21 min). The difference was remarkable with chocolate milk resulting in increased endurance of 43-51%.

Compared to most sports drinks, 2% chocolate milk has slightly more carbohydrate and much more fat and protein. The benefit of chocolate milk may lie in these latter ingredients. Studies have shown that consuming a small amount of protein with carbohydrate during recovery enhances the muscles replenishment of glycogen. Also, a small amount of fat can raise blood levels of free fatty acids which can be used as energy during prolonged exercise.

There are a few problems with the study that might account for a portion of the difference in performance between the endurance trials. Also, the amount of beverage consumed, ~16 oz over a four hour period is probably less than the typical athlete might drink between matches. However, despite those concerns, the study has important implications for soccer, especially at tournament time. The initial exercise bout and the recovery time are similar to what takes place at many tournaments. Despite some of the soccer governing bodies wanting to limit teams to one match per day, most tournaments still require teams to play two matches per day. Usually these matches are separated by 3-4 hours. Thus, the time course of the study simulates tournament conditions, Also, the initial bout of exercise with alternating periods of high and moderate intensity exercise is similar to what is performed during a match.

On balance this study agrees with an earlier post on the Science of Soccer Online. Milk, particularly chocolate milk, seems to be a very effective recovery drink.

 
Energy drinks have 'crossed the line'

Canadian health experts say energy drinks have "crossed the line from beverages to drugs" and are calling on the federal government to regulate the sale of them.

An editorial that appeared on the Canadian Medical Association Journal's website Monday says inadequate labelling requirements and a lack of information about caffeine's harmful effects combine with marketing campaigns that appeal to children to exacerbate the problem.

The editorial says many energy drinks are considered food, so they only need to list ingredients and not natural health products or caffeine content.

"People who are inclined to downplay such concerns might argue that caffeine has been safely consumed in foods for centuries," the editorial says.

"However, marketing of energy drinks is distinctly different from that of other highly caffeinated beverages. Energy drinks are often targeted toward children and youth through carefully designed advertising campaigns as well as sponsorship of events such as snowboarding and skateboarding competitions."

It adds, "Children and youth are notorious for making poor health choices.

They can hardly be expected to make appropriate decisions about consuming energy drinks when information on caffeine concentration and appropriate safe amounts is not visible on these products."

The editorial says Red Bull wasn't available in France until 2008 and it was prohibited to be sold in Denmark in 2009.

The authors said at a minimum, all products with caffeine levels exceeding 100 mg should have labels and warnings. They also said advertising aimed at children needs to stop.

"It is time for health authorities around the world to be awakened and alerted to concerns about energy drinks sold to children. Strict regulations are required if business practices and consumer trends are not curbed," the editorial says.

It calls on federal Health Minister Leona Aglukkaq to "boost her energy toward drafting new legislation in this area."

But Refreshment Canada, a national trade association representing different drink manufacturers, issued a statement Monday afternoon to "correct a number of inaccuracies" in the editorial.

"We strongly agree that energy drinks should be marketed responsibly. In Canada, energy drinks are not sold as foods but as natural health products. They are formulated, labelled and marketed in accordance with Health Canada's natural health products regulation. These energy drinks are intended for adults and clearly indicate on the label that this category of beverage is not recommended for children, pregnant or breastfeeding women and people who are sensitive to caffeine," the statement says. "Contrary to the editorial, energy drink labels also contain additional information on the use, recommended dosage, intended population, any precautions (such as not mixing with alcohol) and lists of medicinal and non-medicinal ingredients, including a clear declaration of caffeine content from all sources."

Refreshment Canada adds, "As with many products, it is important to read the product label and use as directed."

Grassroots

 

Grassroots Workshop

From the ASA website

As part of the Long Term player development and Sports for life initiative the Alberta Soccer Association will conduct Grassroots Workshops throughout the Province of Alberta. The purpose of the workshop is to introduce the Sports for life model as well as provide information with regards to the stages of development specific to soccer players. The information will coincide with the U6-U8-10 booklets that were introduced at the 2010 AGM. The workshops will be approximately 3 hours long and will contain both a classroom session and field session. If your district or zone is interested in hosting a workshop or for further information please contact Eric Munoz Grassroots Coordinator for the Alberta Soccer Association at This e-mail address is being protected from spambots.
