Personal and situational variables that describe coping with acute stress in competitive sport.

The authors examined the degree to which competitive basketball players in Australia were consistent in their cognitive appraisals and coping strategies in response to 4 types of stressful situations that they had experienced during previous basketball games as functions of perceived stress intensity. The authors predicted that both approach and avoidance coping strategies would be dependent on the type of stressful event, in accord with the transactional model. The results supported that prediction: Approach strategies were more prevalent than avoidance strategies following 3 of the 4 events. Cognitive appraisals and perceived stress intensity also strongly influenced the participants' use of coping strategies, accounting for 34% of the variance.

Psychological predictors of coping responses among Greek basketball referees.

The authors examined the effects of situational appraisals (perceived control and intensity), coping styles (monitoring and blunting), and personal dispositions (optimism and self-esteem) on the approach and avoidance coping responses of skilled Greek basketball referees (N = 162) and the consistency of their responses following 3 game-related stressful situations. In an effort to clarify the variables involved in coping and to consider the theoretical principles both within and beyond sports, the authors replicated an earlier study among Australian basketball referees (A. Kaissidis-Rodafinos, M. H. Anshel, & A. Porter, 1997). The results were equivocal: The Greek referees were not consistent in using avoidance and approach coping responses across situations. Approach coping was more predictable than avoidance coping in accounting for both situational and personal variables.

Coping style following acute stress in competitive sport.

The purpose of this study was to ascertain coping styles among competitive athletes in response to various acute stressors. Specifically, the authors used a 134-item survey to measure approach and avoidance coping styles, with task-focused and emotion-focused coping tendencies nested hierarchically as subdimensions under each. Australian and U.S. college-aged participants indicated the extent to which they used approach, avoidance, task-focused, and emotion-focused coping strategies (a 4-factor model) in response to selected acute stressors experienced during sport competition. The authors computed confirmatory factor analysis to test the theoretically driven model. The criterion loading of .30 and above for each of the factors reduced the survey to 65 items. Findings indicated stronger links between the 2 approach constructs of task- and emotion-focused coping than between the 2 avoidance constructs of those subdimensions. The goodness-of-fit indices for the 4-factor model were 0.58 and 0.57 for Australian and U.S. samples, respectively, and .71 overall. Concomitant low correlations between the 2 approach (0.18) and the 2 avoidance dimensions (0.43) reflected relatively high residuals between stressors. In general, psychometric analyses suggest that coping style may be more prevalent in some situations than others, lending partial support for the transactional model of coping.

Personal and situational factors that predict coping strategies for acute stress among basketball referees.

The aim of this study was to establish the ways in which coping style and situational appraisals are related to the consistency of using approach and avoidance coping strategies for skilled Australian basketball referees (n = 133) after three game-related stressful events. The events, 'making a mistake', 'aggressive reactions by coaches or players' and 'presence of important others', were determined from previous research on sources of acute stress among basketball officials. Our findings indicated that: referees exhibited consistent avoidance, but not approach, coping styles; they used more avoidance than approach strategies; and they perceived stress to be positively correlated with approach, and negatively associated with avoidance, coping strategies. These findings suggest that individual differences exist in perceptions of stress (i.e. situational appraisals), controllability and coping styles among moderately and highly skilled basketball referees. The implications for teaching cognitive and behavioural strategies for effective coping with acute stress in basketball officiating are discussed.

Coping style and situational appraisals as predictors of coping strategies following stressful events in sport as a function of gender and skill level.

The purpose of this study was to examine links between coping style, situational appraisals and the subsequent use of coping strategies in response to acute stress among competitive Australian basketball players (N = 190, 93 men and 97 women, ranging in age from 18 to 44 years). Regression analyses indicated that participants' approach and avoidance coping responses varied across four sport-related stressful situations. In addition, both personal and situational factors accounted for significant variation in players' approach coping responses, with situational factors better predictors of approach coping than personal dispositions. For avoidance coping, situational appraisals (i.e. perceived stress and controllability) were again better predictors than personal dispositions. The results lend credence to the interactional (contextual) model of coping in which participants' use of coping strategies is at least a partial function of situational demands.

Examining athletes' attitudes toward using anabolic steroids and their knowledge of the possible effects.

One goal of contemporary sports leaders is to eradicate the use of banned drugs in competitive sport. A common approach to achieving this outcome is to provide athletes with adequate education about the effects of drug use. Ostensibly, educational programs about the deleterious effects of using anabolic steroids are thought to discourage their intake. Thus, the purpose of this study was to examine the relationships between the athletes' knowledge about the long-term effects of anabolic steroids and their attitudes toward this type of drug. Multiple regression analyses indicated relatively low R2's and correlations between the various components of subjects' knowledge and their attitude toward steroid ingestion. This suggests that educational programs for athletes about taking anabolic steroids may have limited value in terms of creating appropriate, responsible attitudes toward this illegal, unethical, and medically questionable practice.

Effect of divergent self-monitoring strategies on motor performance and emotion as a function of alternating task complexity.

The aim of this study was to determine the effectiveness of implementing different self-monitoring (SM) strategies as a function of varying task complexity on a computer game, 'Shufflepuck'. Self-monitoring theory suggests that positive self-monitoring (PSM) results in better performance for difficult tasks, whereas negative self-monitoring (NSM) is preferable for easy tasks. When SM was tested under easy and complex task conditions, it was found that performance effectiveness was a function of matching appropriate task difficulty with the SM strategy. Unpaired t-tests compared the first set of 100 trials (pre-task) with the second set of 100 trials (post-task) on a computer skills game requiring hand-eye coordination. The results showed that subjects who changed from the difficult task/PSM condition to the easy task/PSM condition (different task, same SM strategy) performed significantly poorer (P < 0.001) than subjects who changed from the difficult task/PSM condition to the easy task/NSM condition (different task, different SM strategy). A second unpaired t-test comparing the two sets of difference performance scores indicated that performance was significantly superior for subjects using the PSM than the NSM strategy while performing the difficult task (P < 0.05). That is, changing from the easy task/NSM condition to the difficult task/NSM condition produced poorer performance than changing from the easy task/NSM to the difficult task/PSM condition. In terms of subjects' emotions, the use of NSM and PSM when performing easy and difficult tasks, respectively, resulted in markedly less negative affect (P < 0.01), but did not influence positive affect, on pre- and post-task comparisons. Finally, correlations between affect and performance, based on pre- and post-performance and affect scores, were moderate to high. Implications of the present results for slumps in sport performance are offered.

Effect of chronic aerobic exercise and progressive relaxation on motor performance and affect following acute stress.

The effects of a 10-week aerobic exercise and progressive relaxation training program on somatic, emotional, and behavioral responses to acute stress, as determined by quality of motor performance and affect, were examined. The participants consisted of 60 unfit male university undergraduate students with no previous training in stress management who were randomly and evenly assigned to engage in one of four treatments over 10 weeks: (a) moderate aerobic exercise, (b) progressive relaxation, (c) a placebo group that engaged in group discussion but did experience acute stress, and (d) a nonintervention control group that did not experience stress while performing the motor task. Acute stress consisted of "losing" against a competitor of the opposite sex on the criterion motor task while receiving unpleasant information about their performance over 30 preintervention and 30 postintervention trials. Analyses indicated that aerobic exercisers, in comparisons with the other groups, responded to acute stress with more positive affect, lower stressor task heart rate, reduced systolic (but not diastolic) blood pressure, and superior motor performance. Progressive relaxation markedly reduced systolic blood pressure but did not favorably influence performance or affect in response to acute stress. Placebo and control groups were statistically similar on all measures. The findings indicated support for the use of chronic aerobic exercise as a strategy for improved coping with acute stress.

Examining warm-up decrement as a function of interpolated open and closed motor tasks: implications for practice strategies.

Warm-up decrement (WUD) is a loss in the level of physical performance following rest and prior to subsequent trials. The activity-set hypothesis is one of several explanations for this phenomenon. The purposes of this study were to field test the efficacy of the activity-set hypothesis and explore the effectiveness of performing closed and open interpolated tasks in reducing WUD. The criterion task was hitting tennis ground strokes in response to a ball tossing machine, an open skill. Elite players (n = 20) from a tennis club in New South Wales, Australia, practised either a closed or open task, or rested, prior to resuming the first post-rest trial, using a repeated-measures design. The results yielded partial support of the activity-set hypothesis. Although the closed interpolated task markedly reduced WUD, open skill practice solicited better post-rest performance. Warm-up decrement was clearly evident under the rest condition. Furthermore, post-rest scores were statistically superior for the open skill condition as compared to practising a closed interpolated task, at least for the first two post-rest trials (trials 21 and 22). The implications for these results in reducing WUD are explored within the frameworks of task classification systems and schema theory.

Effect of aerobic and strength training on pain tolerance, pain appraisal and mood of unfit males as a function of pain location.

The purpose of this study was to examine the effect of aerobic and strength conditioning on pain tolerance, pain appraisal and mood as a function of upper and lower limb pain location. Unfit males (n = 48) were randomly assigned to one of four groups: aerobic training, strength training, combined aerobic and strength training, and a 'no training' (control) group. The fitness regimens consisted of exercising at least three times per week for 12 weeks. Pain tolerance and appraisal and mood were ascertained before the treatment (baseline), and after 6 and 12 weeks. Statistical analyses using MANOVA indicated that the presence of aerobic training increased upper limb pain tolerance but was also linked to a more severe pain appraisal compared with the absence of aerobic training. Aerobic work also improved vigour while decreasing fatigue, tension and depression. Strength training had no influence on pain tolerance and positive mood states, but increased depression. Lower limb pain tolerance was unaffected by the treatments.

A test of the COPE model on motor performance and affect.

The effect of a model called COPE which suggests the use of cognitive-behavioral strategies in response to acute stress in sport was tested. Both rotary pursuit performance and changes in affect were similar for 33 subjects in groups who used the COPE model or used only a segment (one strategy) of the model. Both experimental groups performed better and experienced less negative affect after treatment than the control group.

Effects of modelling and observer's ego involvement on warm-up decrement.

Warm-up decrement (WUD), a phenomenon associated with motor behaviour, is the temporary decrement that occurs when performance resumes after a period of inactivity. The purpose of this study was to examine the extent to which observing a model while concerned about one's own subsequent performance (e.g. a substitute about to enter the sport contest) influences WUD. The subjects were randomly assigned to one of four conditions: (1) observing an ego-involved model demonstrate the criterion skill, (2) observing a model while not ego-involved, (3) ego involvement without modelling and (4) resting (control). Performance outcome (accuracy) and arousal (cognitive and somatic) were assessed. The results of the study indicated that only the combined ego involvement plus modelling condition eliminated WUD. Positive rather than negative emotions and heart rate increased significantly for these subjects after rest. In contrast, the other conditions each exhibited WUD. Heart rate was significantly higher in the 'model and ego' and 'ego only' groups as opposed to 'modelling only' and rest. Implications for using cognitive strategies while observing competitors just prior to entering the contest on reducing WUD are discussed.

A field test of the activity-set hypothesis for warm-up decrement in an open skill.

To determine the relative effectiveness of different warm-up activities in eliminating postrest warm-up decrement (WUD), 65 highly skilled tennis players performed 60 forehand and 60 backhand groundstrokes, rested for either 5 or 15 min, engaged in one of five interpolated activities (additional rest, running in place, imagery, practice swings, or air dribbling), and then performed 12 additional forehands and backhands. An analysis of differences between prerest and postrest arousal measures (heart rate, positive cognitive arousal, and negative cognitive arousal) revealed that all of the interpolated activities except additional rest restored arousal to levels near those found at the end of prerest trials. Postrest WUD was also eliminated by practice swings and air dribbling and, to a slightly lesser extent, by running in place. We concluded that an effective warm-up for open skills such as the tennis groundstroke should include some form of overt physical activity that direct the attention of the performer to task-relevant cues.

Effects of different intensities of fatigue on performing a sport skill requiring explosive muscular effort: a test of the specificity of practice principle.

The purpose of this study was to ascertain the effects of high, moderate, and low physical fatigue on performing the shot put, a sport skill that requires explosive muscular effort. 44 subjects practiced the shot put until mastery was achieved. They then experienced one of four fatigue intensities during a 20-trial practice period (no fatigue, 45, 60 or 75% of their predicted maximum oxygen uptake) to induce light, moderate, or heavy fatigue, respectively, after which subjects then engaged in criterion performance for 5 trials under each of the fatigue intensities, with one week in between. Distance thrown and expert assessment of performance technique were dependent variables. Analysis indicated that criterion performance was optimal for both distance and form after subjects experienced light fatigue during practice and criterion performance. The specificity of practice hypothesis was partially supported for the light fatigue condition, but not for the other intensities.

The effect of mood and pleasant versus unpleasant information feedback on performing a motor skill.

The effect of negative, positive, or neutral feedback on a rotary pursuit task as a function of the subject's depressed or elated mood was ascertained. Specifically, the self-schema hypothesis was examined. Ninety female volunteers, ranging in age from 18 to 25 years, participated. They were randomly assigned to one of eight conditions based on depressed or elated mood states, elicited by Velten's (1968) mood induction procedure, and feedback. A control group received no feedback and was not subjected to a mood inducing treatment. Baseline measures and changes in mood were determined by the Multiple Adjective Affective Checklist (MAACL). Bogus feedback was offered after all but one of the trials. The subjects' mood changed significantly during the mood-inducing treatment. For motor performance, partial support was lent to self-schema. Elated and depressed subjects performed best under positive and negative feedback, respectively. The effects, however, were temporary.

Effect of using mechanical devices for baseball batting on warm-up decrement.

The extent to which different mechanical baseball-batting devices used during a rest affected performance immediately after rest (warm-up decrement) was examined. Difference scores between the average of prerest Trials 8, 9, and 10 and each of 10 postrest trials were used to determine the presence of warm-up decrement. It was predicted that the use of a batting-T and the Batter's Aid machine (in which a batter swings at a ball popped up within the strike zone) would result in superior performance measured as the distance (ft.) a ball was hit and frequency of contacts on postrest performance reducing or eliminating the warm-up decrement. Performance of 33 boys, aged 11 and 12 yr., indicated that only use of the Batter's Aid eliminated warm-up decrement with respect to both the distance and frequency as compared to the batting-T and control groups. In addition, the batting-T condition solicited significantly better performance than the controls on the distance measure but was statistically similar to the controls in frequency of contacts. Also, superior performance was significantly related to heightened heart rate, a physiological index of arousal. A primary explanation of the results focused on the effects of heightened physiological and psychological arousal on warm-up decrement.

Effects of Sexual Activity on Athletic Performance.

In brief: One reason behind coaches' prohibitions of sexual activity before sports events may be the belief that abstinence increases frustration, which in turn is displaced into aggressive behavior toward competitors. However, this hypothesis is not always valid. In fact, depriving an athlete of a normal activity may cause guilt and a loss in concentration. Sexual activity throughout training may promote relaxation and positively affect performance. The author concludes that although there is a need for scientific research in this area, it seems that intercourse does not decrease performance unless it is accompanied by late-night socializing, sleep loss, or drinking.

Relationships among selected perceptual-motor tests and teachers' rankings as a function of children's age and sex.

28 third grade (M = 8.4 yr.) and 28 sixth grade (M = 11.8 yr.) children were administered the Body Coordination Test and Gross Motor Skill Test to assess the relationship between these measures as a function of age, sex, and the subjective ratings (ranks) of their physical education teacher. Scores were significantly correlated (.76) for all as were scores within each grade and sex. The teachers' subjective ranking of younger subjects on their general physical performance was significantly related to scores on both tests but only moderately related to general coordination and unrelated to somatic development. Significant correlations were observed for the older subjects for all ranks on the Gross Motor Skill Test but were only moderately related or unrelated on the Body Coordination Test. These tests may have utility in evaluating motor developmental differences among children.
