One Shot—No Hit? Evaluation of a Stress-Prevention Workshop for Adolescent Soccer Players in a Randomized Controlled Trial

Johanna Belz, Jens Kleinert, and Moritz Anderten

) values the quality of usefulness of an intervention in the specific setting where it is offered as a foundation for effectiveness, as interventions cannot be effective if they are not useful. Consequently, researchers and practitioners also propose assessing participants’ perceptions of the usefulness of

usefulness of the 10/5 RJT test for detecting the smallest worthwhile change (SWC) was not evaluated. Given the potential for rebound RSI jump performance to monitor changes in ankle joint stiffness particularly in the eccentric phase, 16 the capacity to sustain high eccentric muscle activity or reactive

The Role of Ability Beliefs and Incentives in Middle School Students’ Intention, Cardiovascular Fitness, and Effort

Zan Gao, Ken R. Lodewyk, and Tao Zhang

This study uncovers the predictive relationship of middle school students’ ability beliefs (self-efficacy and expectancy-related beliefs) and incentives (outcome expectancy, importance, interest, and usefulness) to intention, cardiovascular fitness, and teacher-rated effort in physical education. Participants (N = 252; 118 boys, 134 girls) completed questionnaires assessing their ability beliefs, incentives, and intention for future participation in physical education, and then had their cardiovascular fitness assessed with the Progressive Aerobic Cardiovascular Endurance Run (PACER) test. Students’ effort in class was rated by their respective physical education teachers. Correlation analysis yielded significantly positive relationships between ability beliefs and incentives. Regression results revealed that ability beliefs, importance, interest, and usefulness significantly predicted intention for future participation. Ability beliefs also emerged as significant predictors of PACER test scores whereas self-efficacy was the only predictor of teacher-rated effort. Implications for educational practice are discussed.

A Comparison of the Isometric Midthigh Pull and Isometric Squat: Intraday Reliability, Usefulness, and the Magnitude of Difference Between Tests

The SpeedCourt: Reliability, Usefulness, and Validity of a New Method to Determine Change-of-Direction Speed

Peter Düking, Dennis-Peter Born, and Billy Sperlich

Purpose:

To determine the reliability, usefulness, and validity of 3 different change-of-direction tests on a SpeedCourt (SCCODT) in team-sport players.

Methods:

For reliability and usefulness, 30 players (16 female and 14 male; age 19 ± 3 y, height 169 ± 30 cm, body mass 70 ± 11 kg) performed 3 SCCODTs differing in duration (7–45 s) on 3 occasions 1 wk apart. The total sprint times (TT) and time to change direction (TCD) were analyzed for each SCCODT. For validity, 14 players performed the Illinois Agility Test (IAT) and 505 test on a separate occasion.

Results:

TT for all SCCODTs is reliable (ICC > .79, CV < 5%), useful (TE < SWC0.5), and valid (IAT r > .71, P < .05; 505 test r > .54, P < .05). SCCODT variable TCD may be useful (TE = SWC0.5) but shows limited reliability with ICC >.65 and a CV >5%.

Conclusions:

All SCCODTs are reliable, useful, and valid to detect moderate performance changes regarding TT, with limited reliability for TCD. The quality of assessment improves when players are well familiarized with the SCCODT.

Reliability, Usefulness, and Validity of a Repeated Sprint and Jump Ability Test

Martin Buchheit, Matt Spencer, and Said Ahmaidi

Purpose:

Two studies involving 122 handball players were conducted to assess the reliability, usefulness, and validity of a repeated shuttle-sprint and jump ability (RSSJA) test. The test consisted of 6 × (2 × 12.5-m) sprints departing on 25 s, with a countermovement jump performed during recovery between sprints.

Methods:

For the reliability and usefulness study, 14 well-trained male handball players performed the RSSJA test 7 d apart. Reliability of the test variables was assessed by the typical error of measurement, expressed as a coefficient of variation (CV). The minimal changes likely to be “real” in sprint time and jump power were also calculated. For the validity study, players of seven teams (national to international levels, women and men) performed the RSSJA test.

Results:

CV values for best and mean sprint time were 1.0% (90% CL, 0.7 to 1.6) and 1.0% (90% CL, 0.7 to 1.4). CV values for best and mean jump peak power were 1.7% (90% CL, 1.2 to 2.7) and 1.5% (90% CL, 1.1 to 2.5). The percent sprint and jump decrements were less reliable, with CVs of 22.3% (90% CL, 15.7 to 38.3) and 34.8% (90% CL, 24.2 to 61.8). Minimal changes likely to be “real” for mean sprint time and jumping peak power were -2.6% and 4.8%. Qualitative analysis revealed that the majority of between-team differences were rated as “almost certain” (ie, 100% probability that the true differences were meaningful) for mean sprint and jump performances.

Conclusion:

The RSSJA test is reliable and valid to assess repeated explosive effort sequences in team sports such as handball. Test results are likely to be representative of gender and competition level; thus the test could be used to discriminate across playing standards and monitor fitness levels.

Identification of Children with Movement Problems in Singapore: Usefulness of the Movement ABC Checklist

Helen C. Wright, David A. Sugden, Richard Ng, and John Tan

This investigation is concerned with the identification and assessment of Singaporean primary school children who have developmental coordination disorder (American Psychiatric Association, 1987). The present study forms part of a larger project concerned with the suitability of currently available assessment techniques and intervention programs for use in Singapore. In this paper the usefulness of the Movement ABC Checklist and Test as an assessment instrument is explored. The data on a sample of 212 7- and 8-year-olds compared favorably with data from the standardized sample in the United Kingdom. Age and gender differences were similar, and the effects of increasing task difficulty within the checklist were generally confirmed. The checklist identified 15.6% of children as having movement problems or being at risk, which was close to the value obtained in the U.K. The Movement ABC Test provided evidence of the validity of this figure as it successfully differentiated the selected children from age-matched controls who scored well on the checklist. Although some of the items in both instruments need modification, the results suggest that the Movement ABC package is a workable research tool in the Singaporean context.

The Usefulness of Session Rating of Perceived Exertion for Monitoring Training Load Despite Several Influences on Perceived Exertion

Monoem Haddad, Johnny Padulo, and Karim Chamari

Despite various contributing factors, session rating of perceived exertion has the potential to affect a large proportion of the global sporting and clinical communities since it is an inexpensive and simple tool that is highly practical and accurately measures an athlete’s outcome of training or competition. Its simplicity can help optimize performance and reduce negative outcomes of hard training in elite athletes.
