The interaction of functional and dysfunctional emotions during balance beam performance.

The interaction between functional and dysfunctional emotions, as one of the major tenets of the individual zones of optimal functioning (IZOF) model (Hanin, 2000), was studied in a sport specific setting. Fourteen female gymnasts performed three attempts of a compulsory balance beam routine at three different heights. Heart rate and self-report of functional and dysfunctional emotions were measured during each routine.

The role of preparatory heart rate deceleration on balance beam performance.

Preparatory heart rate deceleration occurs in tasks with an external focus of attention and is often assumed to facilitate balance performance. However, its effects upon sport-related complex balance movements have not been studied. Heart rate patterns during the preparation period of an acrobatic element (flic-flac) on the balance beam were studied in 14 female gymnasts (M age 13.

The measurement of competitive anxiety during balance beam performance in gymnasts.

The purpose of the present study was to investigate competitive anxiety during balance beam performance in gymnasts. Competitive anxiety was assessed continuously by heart rate monitoring and by retrospective self-report of nervousness in eight female national level gymnasts during their balance beam routine during one competition and two training sessions. A significant negative correlation was found between the score of the retrospective self-report of nervousness and performance during the routine.

Treadmill exercise negatively affects visual contribution to static postural stability.

This study was undertaken to explore the nature of impaired postural stability following physical exercise. Nine healthy subjects (aged 24 +/- 3 years) were subjected to 30 min of treadmill walking or running on two separate occasions. Walking and running speeds (1.
