Relative energy deficiency in sport (RED-S) is a syndrome resulting from an energy deficiency relative to the balance between dietary energy intake (EI) and the energy expenditure (EE) required to support homeostasis, health, activities of daily living, growth, and sport. RED-S affects

Originally named the Red Zinger Classic, the Coors International Bicycle Classic was contested for fourteen years, 1975-1988, primarily in Colorado, but expanding to neighboring states and even Hawaii in its later years. As a stage race, this multi-day event featured several individual stages (or

Recent research has revealed that a person or team wearing red is more likely to win a physical contest than a person or team wearing another color. In the present research, we examined whether red influences perceptions of relative dominance and threat in an imagined same-sex competitive context, and did so attending to the distinction between wearing red oneself and viewing red on an opponent. Results revealed a bidirectional effect: wearing red enhanced perceptions of one’s relative dominance and threat, and viewing an opponent in red enhanced perceptions of the opponent’s relative dominance and threat. These effects were observed across sex, and participants seemed unaware of the influence of red on their responses. Our findings lead to practical suggestions regarding the use of colored attire in sport contexts, and add to an emerging, provocative literature indicating that red has a subtle but important influence on psychological functioning.
Product (RED) was launched in 2006 as an initiative to activate the corporate sector in the fight against HIV/AIDS in Africa. In 2009, Nike joined Product (RED)’s list of corporate partners with its “Lace Up, Save Lives” campaign. Nike (RED) directs 100% of its profits toward HIV/AIDS treatment and prevention through the Global Fund to Fight AIDS, Tuberculosis and Malaria and grassroots soccer programs in Africa. This case study questions the symbolism projected by Nike (RED) and its implications by applying Jean Baudrillard’s theories on consumption and hyperreality. The manner in which Nike (RED) represents Africa, HIV/AIDS, soccer, and sport for development and peace are all discussed as mediated simulations that position Nike as the producer of knowledge. Data analysis observes that Nike (RED) laces produce a hyperreality, whereby the origin of truth becomes, according to Baudrillard, indecipherable and soccer becomes more important than HIV/AIDS.

Hill and Barton (2005) showed that fighters in tae kwon do, boxing, and wrestling who wore red jerseys during the 2004 Olympic Games won more often than those wearing blue jerseys. Regarding these results, this study investigated the effects of jersey color during a combat situation on fighters’ physical parameters of strength and heart rate. An artificial, experimental combat situation was created in which the color of sport attire was assigned randomly. Fourteen pairs of male athletes matched for weight, height, and age had to fight each other: once in a red jersey and once in a blue. Heart rate (before, during, and after the fight) and strength (before the fight) were tested wearing the blue and the red jerseys. Participants wearing red jerseys had significantly higher heart rates and significantly higher pre-contest values on the strength test. Results showed that participants’ body functions are influenced by wearing red equipment.

The purpose of this study was to determine the effects of Red Bull energy drink on Wingate cycle performance and muscle endurance. Healthy young adults (N = 15, 11 men, 4 women, 21 ± 5 y old) participated in a crossover study in which they were randomized to supplement with Red Bull (2 mg/kg body mass of caffeine) or isoenergetic, isovolumetric, noncaffeinated placebo, separated by 7 d. Muscle endurance (bench press) was assessed by the maximum number of repetitions over 3 sets (separated by 1-min rest intervals) at an intensity corresponding to 70% of baseline 1-repetition maximum. Three 30-s Wingate cycling tests (load = 0.075 kp/kg body mass), with 2 min recovery between tests, were used to assess peak and average power output. Red Bull energy drink significantly increased total bench-press repetitions over 3 sets (Red Bull = 34 ± 9 vs. placebo = 32 ± 8, P < 0.05) but had no effect on Wingate peak or average power (Red Bull = 701 ± 124 W vs. placebo = 700 ± 132 W, Red Bull = 479 ± 74 W vs. placebo = 471 ± 74 W, respectively). Red Bull energy drink significantly increased upper body muscle endurance but had no effect on anaerobic peak or average power during repeated Wingate cycling tests in young healthy adults.

This study investigated the ergogenic effects of a commercial energy drink (Red Bull) or an equivalent dose of anhydrous caffeine in comparison with a noncaffeinated control beverage on cycling performance. Eleven trained male cyclists (31.7 ± 5.9 y 82.3 ± 6.1 kg, V̇O2max = 60.3 ± 7.8 mL · kg–1 · min–1) participated in a double-blind, placebo-controlled, crossover-design study involving 3 experimental conditions. Participants were randomly administered Red Bull (9.4 mL/kg body mass [BM] containing 3 mg/kg BM caffeine), anhydrous caffeine (3 mg/kg BM given in capsule form), or a placebo 90 min before commencing a time trial equivalent to 1 h cycling at 75% peak power output. Carbohydrate and fluid volumes were matched across all trials. Performance improved by 109 ± 153 s (2.8%, P = .039) after Red Bull compared with placebo and by 120 ± 172 s (3.1%, P = .043) after caffeine compared with placebo. No significant difference (P > .05) in performance time was detected between Red Bull and caffeine treatments. There was no significant difference (P > .05) in mean heart rate or rating of perceived exertion among the 3 treatments. This study demonstrated that a moderate dose of caffeine consumed as either Red Bull or in anhydrous form enhanced cycling time-trial performance. The ergogenic benefits of Red Bull energy drink are therefore most likely due to the effects of caffeine, with the other ingredients not likely to offer additional benefit.
