The Relationship of the Sit and Reach Test to Criterion Measures of Hamstring and Back Flexibility in Adult Males and Females (open access)

The Relationship of the Sit and Reach Test to Criterion Measures of Hamstring and Back Flexibility in Adult Males and Females

The purpose of this study was to examine the criterion-related validity of the sit and reach test as a measure of hamstring and low back flexibility in adult males and females. Subjects were 52 males and 52 females, 20 to 45 years of age. Hamstring flexibility was measured using a goniometer. Spinal flexibility was measured using a tape measure and an inclinometer. The sit and reach test was performed according to the AAHPERD Health Related Fitness Test Manual. Data were analyzed using correlations and appropriate descriptive statistics. Conclusions of the investigation were: 1) in adult males 20 to 45, the sit and reach test is a valid measure of hamstring flexibility but has questionable validity as a measure of low back flexibility, 2) in adult females 20 to 45, the sit and reach test is a moderately valid measure of hamstring flexibility and is not a valid measure of low back flexibility.

A Field Test of Garland's Cognitive Mediation Theory of Goal Setting (open access)

A Field Test of Garland's Cognitive Mediation Theory of Goal Setting

The present study examined Garland's cognitive mediation theory of goal setting in a three-minute basketball shooting task. The effects of different goal conditions were also investigated along with achievement motivation and self-motivation as mediating constructs of performance. Subjects (N=150) were males and females, assigned to one of five goal conditions: "do your best", easy, moderate, hard, and improbable. Results indicated no performance differences between the different goal conditions, with subjects in the "do your best" condition performing as well as subjects in the other goal conditions. Results also yielded partial support for Garland's cognitive mediation theory with task goals influencing performance through its influence on performance expectancy. Furthermore, a negative correlation between achievement motivation and performance was found for females in the improbable goal condition and a positive correlation was found between self-motivation and performance for females in the easy goal condition.

Relationship Between Coaches' Leadership Style and Burnout (open access)

Relationship Between Coaches' Leadership Style and Burnout

The purpose of the present study was to examine the relationship between leadership behavior and perceived burnout of coaches. Head coaches from high schools and from Southeast and Southwest Conference universities were included in the sample (N=302). Coaches completed the Maslach Burnout Inventory (MBI), Leader Behavior Description Questionnaire, Social Desirability Scale and a demographic data sheet. Coaches were separated into two leadership behavior groups and classified as Consideration or as Initiating Structure. It was predicted that coaches in the Consideration Group would have a higher level of perceived burnout. A multivariate analysis of variance was conducted and indicated significant differences in four subscales of the MBI. Specifically, coaches in the Consideration Group scored significantly higher in the frequency and intensity dimension of the emotional exhaustion and depersonalization subscales (p<.001).

A Kinematic Comparison Between Greater-and Lesser-Skilled Powerlifters Doing the Traditional Style Deadlift (open access)

A Kinematic Comparison Between Greater-and Lesser-Skilled Powerlifters Doing the Traditional Style Deadlift

Comparison kinematic models of the traditional style deadlift are presented. Data was obtained through film and analyzed via computer and computer graphics. The comparison between the models revealed that the greater-skilled: 1. used less trunk flexion from the instant of initial trunk lean to the instant of maximum trunk lean, 2. used less knee extension (in same time interval as 1), and 3. demonstrated a smaller horizontal distance between the body center of mass (CM) and the CM of the bar at the instant the bar left the platform. A trend was also observed in which the greater-skilled subjects demonstrated less thoracic lean than the lesser-skilled group at the time the bar reached knee level.
