Abstract

Context: Current devices to assess strength performance in handball may not be sufficiently sports-specific and reliable methods. Functional electromechanical dynamometry is a new technology that allows the development of accurate strength tests in athletes.

Purpose: To determine the absolute and relative reliability and to compare the reliability of the right and left side, and mean and peak force of 3 specific strength tests in handball players with a functional electromechanical dynamometer: unilateral pullover, standing lift, and step forward.

Methods: Fourteen male handball players of the first Spanish division (28.79 [4.81] y; 10.38 [4.63] y of professional experience) performed a repeated-measurement design. Three testing sessions were performed (one per week). The first measurement consisted of 4 isometric tests (right and left unilateral pullover, and right and left standing lift) to obtain isometric peak force, and in the second and third sessions, 6 incremental tests until failure (right and left unilateral pullover, and right and left standing lift, right and left step forward) were performed.

Results: The tests provided high reliability or acceptable reliability for mean and peak strength of unilateral pullover, standing lift and step forward (intraclass correlation coefficient = .83-.97; coefficient of variation = 3.90-11.57). Effect side was negligible in any of the parameters, except for a small effect side in the left peak force for unilateral pullover and a small effect side on the left side for a step forward. Significant differences in reliability (coefficient of variation ratio > 1.15) were found between the right and left sides and peak and mean force in all exercises except peak force in unilateral pullover and step forward.

Conclusion: These results confirm that the tests could be applied to assess physical performance in handball at the same time as regular gym training. Moreover, this is an excellent opportunity to individualize the player's weekly load.

职业手球运动员3项比力测试的复测可靠性。

背景：目前评估手球力量表现的设备可能不是足够针对运动的可靠方法。功能性机电测力仪是一项新技术，可以对运动员进行精确的力量测试。目的：用功能性机电测功机测定手球运动员3项比力测试的绝对可靠性和相对可靠性，并比较左右侧、平均力和峰值力的可靠性。方法：14名西班牙甲级男子手球运动员（28.79[4.81]年；10.38[4.63]年）进行重复测量设计。进行了三次测试（每周一次）。第一次测量包括4次等长测试（右侧和左侧单侧套头衫，右侧和左侧站立提举），以获得等长峰值力。在第二次和第三次测量中，进行了6次增量测试，直到失败（右侧和右侧单侧套头衣，右侧和左侧站立提举，左右向前跨步）。结果：单侧套头衫、立举和向前跨步的平均强度和峰值强度测试具有较高的可靠性或可接受的可靠性（组内相关系数=0.83-0.97；变异系数=3.90-11.57），除了用于单侧套头衫的左侧峰值力中的小作用侧和用于向前跨步的左侧上的小影响侧之外。除了单侧套头衫和向前跨步的峰值力外，所有练习中，左右两侧以及峰值力和平均力的可靠性存在显著差异（变异系数>1.15）。结论：这些结果证实了这些测试可以在常规体育训练的同时用于评估手球的身体表现。此外，这是一个很好的机会来个性化球员的每周负荷。

期刊介绍： The Journal of Sport Rehabilitation (JSR) is your source for the latest peer-reviewed research in the field of sport rehabilitation. All members of the sports-medicine team will benefit from the wealth of important information in each issue. JSR is completely devoted to the rehabilitation of sport and exercise injuries, regardless of the age, gender, sport ability, level of fitness, or health status of the participant. JSR publishes peer-reviewed original research, systematic reviews/meta-analyses, critically appraised topics (CATs), case studies/series, and technical reports that directly affect the management and rehabilitation of injuries incurred during sport-related activities, irrespective of the individual’s age, gender, sport ability, level of fitness, or health status. The journal is intended to provide an international, multidisciplinary forum to serve the needs of all members of the sports medicine team, including athletic trainers/therapists, sport physical therapists/physiotherapists, sports medicine physicians, and other health care and medical professionals.
