Background: Pain from the lateral aspect of the elbow is a common symptom in racket sports, both in recreational and competitive players. In Tennis elbow (TE), the pain is elicited from the lateral epicondyle and the common extensor origin just distal of the epicondyle. The symptoms are aggravated by gripping activity and might be related to activity level, in work as well as in recreational or elite racket sports. TE is considered to be an overuse injury of degenerative nature and the diagnose is easily made, based on a typical history and clinical findings. Objective: To present current knowledge concerning management of TE in racket sports by a review of the literature. Methods: Narrative literature review. Results: An overview of TE in racket sports with highlight on the clinical features, alternative diagnoses and suggested treatments in the literature. Since TE is considered to be an overuse injury, the paper also provides advises for training plan besides management until resolution of symptoms. Conclusions: This painful condition is self-limiting with a good prognosis. No treatment has convincingly evidence, besides methods for reducing pain symptoms. When the pain symptoms are under control, it is important that the return to racket sports is gradual.

Studies have shown the importance of sleep on tennis skill execution; however, its influence on physical performance metrics is unclear. This study aimed to examine the extent to which sleep duration and sleep quality metrics influence physical performance metrics in junior tennis players. Thirty-six junior tennis players from Australia and Germany completed the Consensus Sleep Diary over seven nights. A novel total sleep score based on current National Sleep Foundation recommendations was generated (calculated as the percentage of the average standardised sleep metrics), for each player. Players physical performance was measured using a comprehensive tennis-specific testing battery. This included sit and reach test for flexibility, counter movement jump and overhead medicine ball throw for power, 5-, 10- and 20-metre sprints for speed, tennis agility test for agility and reaction time, grip strength for strength, repeat sprint ability for anaerobic capacity and the Hit and Turn Tennis Test for aerobic capacity. Teenage (14 to 17 years of age) players reported significantly lower sleep duration (471 ± 116 min versus 543 ± 72 min; p <0.001, d = 0.83) and sleep efficiency (90% ± 11% versus 94 % ± 5%; p = 0.011, d = 0.49) metrics than school-aged players. Players with higher self-reported sleep quality had slower reaction times during a tennis agility test (r = 0.604, p = 0.011). However, players who reported feeling more rested and refreshed had faster reaction times during a tennis agility test (r = -0.579, p = 0.020). No other significant associations were present between self-reported sleep metrics and physical performance metrics. Nevertheless, feeling well-rested and refreshed, one of the primary outcomes of sleep, improves reaction time during a tennis-specific agility test. However, physical performance metrics are not significantly influenced by small variations in recommended sleep duration and sleep quality ranges.
研究表明睡眠对网球技术执行的重要性;然而，它对物理性能指标的影响尚不清楚。本研究旨在探讨睡眠时间和睡眠质量指标对青少年网球运动员身体表现指标的影响程度。来自澳大利亚和德国的36名青少年网球运动员在7个晚上完成了“共识睡眠日记”。根据目前国家睡眠基金会的建议，为每个球员生成了一个新的总睡眠评分(以平均标准化睡眠指标的百分比计算)。运动员的体能表现是用一套全面的网球专项测试系统来测量的。这包括静坐和伸展测试柔韧性，反动作跳跃和头顶投球测试力量，5米，10米和20米短跑测试速度，网球敏捷性测试敏捷性和反应时间，握力测试力量，重复冲刺能力测试无氧能力，网球击球和转身测试有氧能力。青少年(14至17岁)玩家报告的睡眠时间明显较短(471±116分钟vs 543±72分钟);P <0.001, d = 0.83)和睡眠效率(90%±11% vs 94%±5%;P = 0.011, d = 0.49)。在网球敏捷性测试中，自我报告睡眠质量较高的运动员反应时间较慢(r = 0.604, p = 0.011)。然而，在网球敏捷性测试中，那些感觉更休息、更精神的球员的反应时间更快(r = -0.579, p = 0.020)。在自我报告的睡眠指标和身体表现指标之间没有其他显著的关联。然而，睡眠的主要结果之一是感觉休息得很好，精神焕发，在网球专项敏捷性测试中提高反应时间。然而，推荐睡眠时间和睡眠质量范围的微小变化对身体表现指标没有显著影响。

To avoid the drawbacks of optical video-based motion capture systems and due to the ongoing miniaturization of integrated sensors, an increasing variety of sensor-based systems has been used for motion capture in sports. Meanwhile, there are ready-made, commercially available solutions that claim to be capable of recording reliable kinematic data. This research project focuses on the question of whether a commercially available badminton racket with an integrated sensor device (Oliver® Plasma TX 5) provides meaningful data for diagnostic and training purposes in elite sports. Therefore, 16 elite badminton players executed jump smashes using this sensor racket while the kinematics of the stroke technique were recorded using a high speed video-based system. Bland-Altman plots were applied to analyze the agreement between the two systems. The plots revealed a systematic bias and 95% limits of agreement ranging from 6% to 23%: The detection of stroke techniques showed a 42% rate of success. These data show that the measurement accuracy of the sensor racket is not sufficient for use in diagnostics or training. Future development of the sensor racket could include a method to calibrate the system prior to a measurement, in addition to correcting the underlying algorithm to reduce the bias.
