Since 1930—with the exception of the break for World War II—every four years, the world’s best national teams face off in a soccer tournament. The last two tournaments hosted by South Africa in 2010 and Brazil in 2014 will be the emphasis of this paper. Each tournament featured the thirty-two countries and captured a television audience of over three billion people throughout the month-long tournament, one billion of which tuned in for the final. For comparison, the Super Bowl XLIX where the New England Patriots defeated the Seattle Seahawks 28 to 24 was the most watched event in United States’ history with a viewership of 114.4 million people.
Countries spend years planning and preparing to win a bid to host one of these mega events. Bids are often times awarded eight to twelve years in advance. There has been a recent trend of developing countries hosting the FIFA World Cups and the future bids already awarded follow that trend. Many people ask the question of whether all the money spent on infrastructure, construction, and tourism to host this tournament and gain international exposure are really worth it? Simply put, the 2010 FIFA World Cup was valuable to South Africa while the 2014 FIFA World Cup was not worth the costs to Brazil.
This study aimed to investigate the effects of specific macronutrient feedings on competitive golf performance and perceived levels of fatigue and alertness. Participants played three, nine hole rounds of golf, consuming an isocaloric beverage as a control (CON), with the addition of carbohydrate (CHO), or combination of protein and carbohydrate (COM). Physiological and performance measurements were taken before, during, and following each nine hole round. Performance measurements include driving accuracy (DA), driving distance (DD), iron accuracy (IA), chipping accuracy (CA), and putting accuracy (PA). Pre-golf hydration status (urine specific gravity [USG]) and Sweat Rate during golf performance showed no significant differences between trials. All nine hole rounds were performed in ~2 hours. Environmental conditions were similar for all three testing days (mean WBGT=10.946). No significant differences were seen in Driving Distance, Driving Accuracy, and Iron Accuracy for all nine holes between groups receiving different macronutrient feedings. Chipping Accuracy was significantly better in CON trial compared to CHO (p=0.004) and COM (p=0.019). No significant differences were seen in putting make percentages. COM trial significantly lowered Perceived Levels of Fatigue (p=0.019) compared to CON. The CHO trial showed significant improvements in DA compared to CON (13.7 vs. 44.1, p=0.012) and COM (13.7 vs. 33.6, p=0.004) in the first four holes. In the last five holes, the COM trial showed significant improvements in DA compared to CHO (17.5 vs. 29.7, p=0.007). Low Handicap golfers (3 +/- 3) performed significantly better than High Handicap golfers (14 +/- 3.6) in DD (265 vs. 241, p<0.001), DA (15.0 vs. 29.3, p=0.004), IA (15.2 vs. 25.2, p<0.001), CA (52.0 vs. 61.5, p=0.027), and PA 5ft (64% vs. 40%, p=0.003). High Handicap players showed no significant differences between the three trials for any golf performance measurements. Low Handicap players showed significant improvements in DA for COM trial compared to CON trial (13.6 vs. 27.6, p=0.003). The results suggest that carbohydrates at the start and a combination of carbohydrate and protein is beneficial at the second part of 9 holes to improve golf performance and maintain levels of fatigue, however, it needs to be investigated how this knowledge will relate to playing more holes.
