Visnes, H., Bache-Mathiesen, L. K., Yamaguchi, T., Gilhuus, H. P., Algaard, K. R. H., Hisdal, E., Bahr, R. “… Background: The long-term prognosis of jumper's knee and whether structural changes in the patellar tendon persist is unknown. Purpose: To investigate whether limitations in knee function and structural changes persisted beyond the athletic career of young elite volleyball players.  …”

Zech, A., Hollander, K., Junge, A., Steib, S., Groll, A., Heiner, J., Nowak, F., Pfeiffer, D., Rahlf, A. L. “… Although female sex is considered a risk factor, it is still unknown whether female and male team-sport players, in fact, differ in their injury rates.  …”

Frese, C. “… Even though kinematic and kinetic differences between indoor and sand condition for different jump types could be proven (1,2), the influence of sand type on those jumps and on injury potential is unknown (3,4). Hence, the aim of this study is to investigate biomechanical variables for the hard floor condition and two sand types differing in degree of hardness.  …”

Piatti, M., Turati, M., Bigoni, M., Gaddi, D. “… Italy and especially the Lombardy region were seriously hit by COVID-19, causing high pressure on hospitals and intensive care; nurses and doctors from every specialization (surgeons, radiologists, orthopedics, dermatologists, etc.) in the main hospitals were rapidly converted to the front line against a new disease with unknown mid-long-term effect and consequences. Simultaneously, the Italian government—as the first one in Europe—took drastic measures limiting the daily life of everyone.  …”

Cheng, X., Ikenaga, T. “… The unknown player role makes individual player unreliable and loses the contribution of each player in the strategy analysis.  …”

Vereijken, A., Aerts, I., Jetten, J., Tassignon, B., Verschueren, J., Meeusen, R., van Trijffel, E. “… Even though functional performance tests are often used to make return to sport decisions, it is unknown whether functional performance is associated with return to performance after such injuries.  …”

Silva, A. M., Matias, C. N., Santos, D. A., Thomas, D., Bosy-Westphal, A., Müller, M. J., Heymsfield, S. B., Sardinha, L. B. “… INTRODUCTION: Magnitude and variation in energy balance (EB) components over an athletic season are largely unknown. PURPOSE: We investigated the longitudinal changes in EB over one season and explored the association between EB variation and change in the main fat-free mass (FFM) components in highly trained athletes.  …”

Janssen, I., Steele, J. R., Brown, N. A. T. “… Although high patellar tendon loading is thought to be a causative factor of patellar tendinopathy, it remains unknown how landing technique is related to high patellar tendon loading.  …”

van Ark, M., Docking, S. I., van den Akker-Scheek, I., Rudavsky, A., Rio, E., Zwerver, J., Cook, J. L. “… The critical tendon load that affects tendon structure is unknown. The aim of this study was to investigate patellar tendon structure on each day of a 5-day volleyball tournament in an adolescent population (16-18 years).  …”

Janssen, I., Steele, J., Munro, B., Brown, N. “… However, whether between-sex variations in landing technique account for differences in patellar tendon loading is unknown. Objective: Our objective was to compare the landing technique and patellar tendon loading in male and female volleyball players.  …”

Mok, K. M., Jarning, J. M., Hansen, B. H., Bahr, R. “… However, the ability of identifying jumping activity from other volleyball specific activity is unknown. Objective: To investigate the feasibility of using accelerometer to identify jumping activity from non-jumping activity in volleyball.  …”

Schmitz, G., Effenberg, A.O. “… Motor control and cognitive executive control are interrelated, but the underlying mechanisms are largely unknown. 10 weeks of table tennis training can improve executive control in children with developmental coordination disorder (Tsai, 2009).  …”

Brewer, M. E., Tucker, W. S. “… Context: Changes to the shoulder complex, such as postural impairment, muscle length and scapular dyskinesis, have been associated with shoulder injuries in overhead athletes. It is unknown if some amount of change in shoulder kinematics is normal as a result of participating in an overhead sport regardless of the presence of shoulder injury.  …”

Eliakim, A., Portal, S., Zadik, Z., Rabinowitz, J., Adler-Portal, D., Cooper, D. M., Zaldivar, F., Nemet, D. “… The gender-specific effect of exercise on these systems in adolescents is unknown. Therefore, the purpose of this study was to evaluate the effect of a typical volleyball practice on anabolic (GH, IGF-I, and testosterone) and catabolic hormones (cortisol) and inflammatory mediators (interleukin-6 [IL-6]) in elite, national team level, male (n = 14) and female (n = 13) adolescent volleyball players (13-18 years, Tanner stage 4-5).  …”
