Using an evaluative priming procedure, this study tested whether automatic evaluations of running differ among groups based on their amount of exercise and whether they were runners or not. Ninety-five participants (26 ± 5.06 years; 46% female) were divided into five groups: an inactive group, active exercisers, highly active exercisers, active runners, and highly active runners. A priming effect score was calculated based on the concept of response facilitation or inhibition: the reaction is faster when the target and prime are valence congruent and becomes slower if they are incongruent. The highly active runner group differed significantly from the inactive group (p < .01) and from the active exerciser group (p < .05). Furthermore, reflective evaluations were measured via questionnaires. The results show that priming effect scores can detect automatic evaluations of running, and they differ not only because of the amounts of physical exercise but also because of their preferred type of exercise.

When anticipating future events like an opponent’s stroke direction in tennis, players are assumed to rely on both kinematic and contextual cues such as an opponent’s on-court position. However, knowledge of position dependency in shot-direction probabilities and experimental evidence of the effect of on-court position on action-outcome anticipation is missing. Here we show that shot-direction probabilities vary as a function of a hitting player’s on-court position in professional tennis. Moreover, unlike novices, skilled players in particular relied on information about an opponent’s position when anticipating forehand baseline shot direction in a video-based experiment. The position dependency in skilled players’ prediction behavior was most evident when little information on an opponent’s stroke kinematics was available. Findings suggest that skilled players consider the reliability of different information sources by weighting the available contextual and kinematic cues differently in the course of an opponent’s unfolding action.

A major element in expert sports performance, particularly racket-and-ball games, is excellent anticipatory skill. A prestudy combined the temporal and spatial occlusion paradigms to ascertain which key stimuli badminton players use for anticipating the direction of overhead shots. The main study then evaluated a program for training anticipatory skills; 200 video clips were employed to orient attention toward these key stimuli. Participants were 63 badminton novices, 20 national league players, and 21 local league players. A transparent red patch (exogenous orienting) was used to orient attention toward the trunk up to 160 ms before racket-shuttle contact; the arm, from 160 ms to 80 ms before contact; and the racket, from 80 ms before to actual contact. Results showed that badminton novices who trained with this program significantly improved their anticipatory skill between post- and retention test compared with controls. Whereas local league players improved from pre- to posttest, training had no effect on expert national league players. It is concluded that using red transparent patches to highlight the most informative cues in perceptual training programs is a promising way to improve anticipatory skill.

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 aim of this study was to examine differentiated effects of internally focused attention in endurance sports. Thirty-two active runners ran 24 min on a treadmill at a fixed speed of moderate intensity. For each 6-min block, participants had to direct their attention on different internal aspects (movement execution, breathing, or feeling of the body) or received no instructions. Oxygen consumption (VO₂) was measured continuously to determine running economy. Results revealed that the different internal focus instructions had differentiated effects on VO₂: A focus on breathing as well as a focus on the running movement led to higher VO₂ than a focus on feeling of the body which showed similar VO₂ as the control condition. We conclude that an internal focus of attention is solely detrimental to performance when directed to highly automated processes (e.g., breathing or movement). However, an internal focus on how the body feels during exercise does not disrupt movement efficiency.

This study investigated the effect of cognitive fatigue on physical performance in a paced running task. Experienced runners (n = 20) performed two 3,000-m runs on an indoor track, once after cognitive fatigue, and once under nonfatigued conditions. Completion times were significantly slower in the cognitive fatigue condition (M = 12:11,88 min, SD = 0:54,26), compared with the control condition (M = 11:58,56 min, SD = 0:48,39), F(1, 19) = 8.58, p = .009, eta²p = .31. There were no differences in heart rate, t(17) = 0.13, p > .05, blood lactate levels, t(19) = 1.19, p > .05, or ratings of perceived exertion F(1, 19) = .001, p 3 .05. While previous research has examined the impact of cognitive tasks on physical tasks, this is the first study to examine a self-paced physical task, showing that cognitive activity indeed contributes significantly to overall performance. Specifically, cognitive fatigue increased the perception of exertion, leading to lesser performance on the running task.

Although attentional focusing in sports has been broadly investigated, the findings vary when it comes to endurance sports. This study provides a comparison between relevant foci in the literature of running economy. These include two internal foci—one addressing automated processes (running movement) and the other nonautomated processes (internal body signals and perceived exertion), an external focus (video) and a control condition. Furthermore, we investigated the influence of interoceptive sensitivity on oxygen consumption within the different attention conditions. Thirty recreational runners performed a four 6-min run at moderate intensity consisting of the four counterbalanced conditions. Running economy was assessed by spiroergometry, and interoception was measured using a heartbeat tracking task. Results revealed a significantly better running economy for the external focus of attention compared with all other conditions. No significant correlations were observed between the heartbeat perception score and oxygen consumption in any condition.
