Based on the Dualistic Model of Passion (Vallerand et al., 2003), a sequence involving the determinants and affective experiences associated with two types of passion (harmonious and obsessive) toward sport was proposed and tested. This sequence posits that high levels of sport valuation and an autonomous personality orientation lead to harmonious passion, whereas high levels of sport valuation and a controlled personality orientation facilitate obsessive passion. In turn, harmonious passion is expected to lead to positive affective experiences in sport but to be either negatively related or unrelated to negative affective experiences. Conversely, obsessive passion is hypothesized to be positively related to negative affective experiences in sport but to be either negatively related or unrelated to positive affective experiences. Results of three studies conducted with recreational and competitive athletes involved in individual and team sports provided support for the proposed integrative sequence. These findings support the role of passion in sport and pave the way to new research.

frequency [HF, in milliseconds squared]) were significantly altered compared with rest days. Interestingly, in a recent study 6 it was shown that late-night soccer training did not affect HRV indices, using the “hour-by-hour” method (recording all RR intervals over the night sleep) as proposed by Myllymaki

This study examined the affective response pattern of severely injured athletes. Five athletes from an NCAA Division I university athletic program were followed within 24 hours of injury for 4 weeks. On two nonconsecutive days a week at the same time and place, the athletes completed the Profile of Mood States and indicated their perceived percent rehabilitation. In addition, at the first meeting the athletes were given the Marlowe-Crowne Social Desirability Scale and a demographic data sheet. At the final meeting the athletes completed an open-ended questionnaire designed to explore affective, cognitive, and behavioral reflections about rehabilitation. ANOVA indicated that affect significantly changed (p<.05) across the 4 week period. Post hoc analyses indicated that this change fits a two-stage process: Stage 1, Times 1−2; Stage 2, Times 3−8, with the two stages being significantly different from each other. The correlation between perceived rehabilitation and total mood disturbance was r=−.69, p<.0001. Correlations for each affective measure and perceived rehabilitation indicated that affective patterns of the rehabilitating athlete were highly related to the perception of rehabilitation, with negative affect diminishing and positive affect increasing as perceived rehabilitation increased.

The purpose of this article is to present the procedural steps used to derive a person’s Individual Affect-Related Performance Zones (IAPZs). An IAPZ is that range of affect (i.e., arousal and pleasure) within which an individual has a probability of performing at a particular level (e.g., optimal, moderate, or poor). This methodology has been used in a number of research studies but has yet to be operationalized in the literature. The purpose of this procedure is to facilitate training programs designed to improve human performance in any number of domains via idiosyncratic control over affect. The methodology described consists of eight steps: (a) collecting data, (b) categorizing affect and performance level, (c) converting the data, (d) performing logistical ordinal regressions, (e) creating IAPZ curves, (f) creating IAPZ profile charts, (g) plotting within competition states onto IAPZ profile charts, and (h) utilizing IAPZs to select, implement, and evaluate performance enhancement strategies.

In the current study, variables grounded in social cognitive theory with athletes with disabilities were examined. Performance, training, resiliency, and thought control self-efficacy, and positive (PA) and negative (NA) affect were examined with wheelchair basketball athletes (N = 79). Consistent with social cognitive theory, weak to strong significant relationships among the four types of self-efficacy (rs = .22–.78) and among self-efficacy and affect (rs = -.40–.29) were found. Basketball players who were efficacious in their ability to overcome training barriers were also confident in their basketball skills and efficacious in their ability to overcome ruminating distressing thoughts while simultaneously cultivating positive thoughts. Athletes with strong resiliency and thought control efficacy also reported more PA and less NA. Multiple regression analyses indicated that the four efficacies predicted 10 and 22% of the variance in PA and NA, respectively.

Cognitive-Affective Stress Management Training (SMT) is a coping skills training program designed to help athletes control dysfunctional stress processes (Smith, 1980). The present quasi-experimental study investigated the effects of SMT on affect, cognition, and performance in high performance youth volleyball players. Members of Alberta's Canada Games men's and women's (under 19 years of age) volleyball teams were assigned to either an experimental treatment group or a waiting-list control group. The treatment program consisted of eight modules, approximately 1 week apart, that allowed subjects to learn and apply somatic and cognitive coping skills. The results indicated that the treatment group emitted fewer negative thoughts in response to videotaped stressors and had superior service reception performance in a controlled practice compared to the control group. There were no interpretable differences between groups for either state anxiety (CSAI-2) or trait anxiety (SCAT). The cognitive and performance measures provided converging support for Smith's program. The results are discussed in terms of coping skills training, theoretical issues regarding the measurement of anxiety, and possible affect-cognition system independence.

By manipulating trunk angle in ergometer cycling, we studied the effect of body configuration on muscle recruitment and joint kinematics. Changing trunk angle affects the length of muscles that span the hip joint. It is hypothesized that this affects the recruitment of the muscles directly involved, and as a consequence of affected joint torque distributions, also influences the recruitment of more distal muscles and the kinematics of distal joints. It was found that changing the trunk from an upright position to approximately 20 deg forward or backward affected muscle activation patterns and kinematics in the entire lower limb. The knee joint was the only joint not affected by manipulation of the lengths of hip joint muscles. Changes in trunk angle affected ankle and hip joint kinematics and the orientation of the thigh. A similar pattern has been demonstrated for muscle activity: Both the muscles that span the hip joint and those acting on the ankle joint were affected with respect to timing and amplitude of EMG. Moreover, it was found that the association between muscle activity and muscle length was adapted to manipulation of trunk angle. In all three conditions, most of the muscles that were considered displayed some eccentric activity. The ratio of eccentric to concentric activity changed with trunk angle. The present study showed that trunk angle influences muscle recruitment and (inter)muscular dynamics in the entire limb. As this will have consequences for the efficiency of cycling, body configuration should be a factor in bicycle design.

Little information exists as to the exercise intensity that adolescents enjoy and whether identifiable subgroups of adolescents will choose higher-intensity exercise.


Healthy adolescents (N = 74; mean age = 11.09 years) completed a cardiorespiratory fitness test, a moderate-intensity exercise task, and an exercise task at an intensity that felt “good.” Heart rate (HR), work rate (WR), and ratings of perceived exertion (RPE) were assessed every 3 minutes.


During the “feels good” task, adolescents exercised at a HR recognized as beneficial for cardiovascular health (mean HR = 66% to 72% of HR at VO2peak). Adolescents who experienced a positive affective shift during the moderate-intensity task engaged in higher-intensity exercise during the feels-good task as compared with those whose affective response to moderate-intensity exercise was neutral or negative (76% of peak HR vs. 70% of peak HR, P < .01).There was no difference between groups in RPE.


Adolescents tend to select an exercise intensity associated with fitness benefits when afforded the opportunity to choose an intensity that feels good. An identified subgroup engaged in higher-intensity exercise without a commensurate perception of working harder. Encouraging adolescents to exercise at an intensity that feels good may increase future exercise without sacrificing fitness.

If ankle joint cryotherapy impairs the ability of the ankle musculature to counteract potentially injurious forces, the ankle is left vulnerable to injury.


To compare peroneal reaction to sudden inversion following ankle joint cryotherapy.


Repeated measures design with independent variables, treatment (cryotherapy and control), and time (baseline, immediately post treatment, 15 minutes post treatment, and 30 minutes post treatment).


University research laboratory.

Patients or Other Participants:

Twenty-seven healthy volunteers.


An ice bag was secured to the lateral ankle joint for 20 minutes.

Main Outcome Measures:

The onset and average root mean square amplitude of EMG activity in the peroneal muscles was calculated following the release of a trap door mechanism causing inversion.


There was no statistically significant change from baseline for peroneal reaction time or average peroneal muscle activity at any post treatment time.


Cryotherapy does not affect peroneal muscle reaction following sudden inversion perturbation.

Although athletic burnout is a frequent topic of discussion and speculation, little in the way of a conceptual model or empirical data currently exists. An attempt is made to incorporate what is known about the nature, causes, and consequences of burnout within a cognitive-affective model of stress and to note the parallel situational, cognitive, physiologic, and behavioral components of stress and burnout. Thibaut and Kelley's social exchange model is used to define the conditions under which withdrawal from a sport can be attributed to burnout. Empirical findings concerning the causes and consequences of burnout derived from nonathletic populations are incorporated within the athletic burnout model, and its implications for preventing and coping with burnout are discussed. A number of conceptual and methodological issues are discussed, including operationalizing and measuring athletic burnout, the need for epidemiological research, and the assessment of causal and moderator variables. Based upon the literature on burnout in nonsport environments and the literature on sources and consequences of athletic stress, a number of testable hypotheses are advanced.
