Gautier, H., Cavailles, O., Gernigon, C. “… However, how these patterns evolve remains unknown. The present study aimed to identify their dynamics during momentum phases and across their succession in football matches.  …”

Hecht, S., Choi, Y. J., Stroux, A., Beuer, F., von Stein-Lausnitz, M., Bechtold, T. E. “… However, the extent of impact, that BS can have on muscle strength, has been attested to be unknown. Therefore, we wanted to investigate the influence of occlusion on the isokinetic strength parameters of the thigh muscles.  …”

Zhang, G., Brink, M., aus der Fünten, K., Tröß, T., Willeit, P., Meyer, T., Lemmink, K., Hecksteden, A. “… ., the hazard curve) is largely unknown. Given the economic and competitive implications of injury burden, this knowledge gap impedes on RTP decision-making and post-RTP player management.  …”

Jackson, D. T., Blagrove, R. C., Thain, P. K., Weldon, A., Clark, C. C. T., Kelly, A. L. “… However, the running speed demands of professional teams at this level remain unknown. Therefore, this study aimed to investigate (1) the match running speed demands in a professional NLF team, and (2) the impact of changing the Head Coach on these physical demands.  …”

Jørgensen, R. B., Pedersen, L. T., Nielsen, T., Egebæk, H. K., Jensen, R. “… Sprint and change of directional performance can be improved by previously conducting a priming protocol. However, it is unknown if this priming-induced performance enhancement is long-lasting.  …”

Pecci, J., Sañudo, B., Ramirez-Campillo, R., Saez de Villarreal, E. “… Conclusion: NHE lengthens the fascicle, especially if a sufficient volume (ie, >290 repetitions) and 2 days per week are performed. It is still unknown how the programming of some fundamental variables such as intensity, degree of effort, or exercise selection affects the muscle architecture of the biceps femoris long head. …”

Harries, S., Clayton, D., Johnson, M., Burberry, R., Varley, I. “… However, empirical research has predominantly focused on endurance-based sports and `real-time` glucose responses during a professional competitive football match remain unknown. This study aimed to evaluate the feasibility and utility of CGM in elite football and the applications for practice.  …”

Zhang, G., Brink, M., aus der Fünten, K., Tröß, T., Willeit, P., Meyer, T., Lemmink, K., Hecksteden, A. “… However, the time course of injury risk after RTP (the hazard curve) as well as its influencing factors are largely unknown. This knowledge gap, which is arguably due to the volatility of instantaneous risk when calculated for short time intervals, impedes on informed RTP decision making and post-RTP player management.  …”

Jerome, B. W. C., Stoeckl, M., Mackriell, B., Dawson, C. W., Fong, D. T. P., Folland, J. P. “… However, match play is increasingly considered as distinct phases of play, although the influence of phase of play on match physical demands remains largely unknown. This study compared physical intensity, acceleration and deceleration demands, between phases of play and according to playing position.  …”

Oliveira, P., Moura, F. A., Baptista, I., Nakamura, F. Y., Afonso, J. “… However, inter-positional differences are unknown. This study aimed to explore the variability of acceleration and deceleration (Acc) distribution curves according to players` positions during soccer matches.  …”

Varillas-Delgado, D. “… However, the genetics involved in response to supplementation is unknown. The aim of this study was to analyse, for the first time, the relationship between muscle performance-related genes and the risk of an increased body mass index (BMI) and muscle mass and a decrease in fat mass in professional football players after creatine supplementation.  …”

Benediktsson, S., Johannsson, E., Rygh, C. B., Gundersen, H. “… Whether this affect physical capacity is unknown. Thus, the first aim of the present study is to compare physical capacity between players from Iceland and Norway.  …”

Maestroni, L., Turner, A., Papadopoulos, K., Pedley, J., Sideris, V., Read, P. “… Single leg drop jump (SLDJ) assessment is commonly used during the later stages of rehabilitation to identify residual deficits in reactive strength but the effects of physical capacity on kinetic and kinematic variables in male soccer players following ACL reconstruction remain unknown. Isokinetic knee extension strength, kinematics from an inertial measurement unit 3D system and SLDJ performance variables and mechanics derived from a force plate were measured in 64 professional soccer players (24.7 ± 3.4 years) prior to return to sport (RTS).  …”

Kelly, A. L., Williams, C. A., Jackson, D. T., Turnnidge, J., Reeves, M. J., Dugdale, J. H., Wilson, M. R. “… However, the interaction between these two factors is relatively unknown. The aim of this study was to investigate the implications of socioeconomic status and psychological characteristics in English academy soccer players (n = 58; aged 11 to 16 years).  …”

Teixeira da Silva, J. A., Nazarovets, S., Carboch, J., Deutscher, C., Almeida, C. H., Webb, T., Scelles, N. “… Given the overwhelming support evidenced by its broad adoption, but also some criticisms and concerns about this technology, an objective assessment of the growing literature on VAR is timely to take stock of what is known and what is still unknown about its use and perception. Using primarily indexed English literature from 2018 to 2024, this narrative review aims to gauge four main talking points related to VAR, including, but not limited to, the technology used, why VAR is perceived as controversial, and its perception in a socio-cultural context.  …”

Martinho, D. V., Rebelo, A., Field, A., Ribeiro, A. S., Pereira, F., Bizarro, B., Ribeiro, J., Len, S. M., Gouveia, É. R., Sarmento, H. “… The interaction between training load and physical performance is unknown during a preseason period in youth soccer players.  …”

Stables, R. G., Anderson, L., Sale, C., Hannon, M. P., Dunn, R., Tang, J., Fraser, W., Costello, N. B., Close, G. L., Morton, J. P. “… The effect of inadequate carbohydrate (CHO) intake pre-, during and post-training upon skeletal structures remain unknown. Therefore the aim of this study was to test the hypothesis that training with reduced CHO availability increases bone resorption in adolescent soccer players.  …”

Armitage, M., McErlain-Naylor, S. A., Devereux, G., Beato, M., Iga, J., McRobert, A., Roberts, S., Buckthorpe, M. “… Introduction: Return to play related research is increasing rapidly, with two recent competency-based frameworks offering conceptualised support for on-field rehabilitation (OFR) decision-making. It is still unknown, however, who is responsible for OFR and how they typically select, monitor, and progress OFR processes.  …”

Massamba, A., Barbi, C., Kouzkouz, N., Gény, B., Favret, F., Hureau, T. J. “… However, the mechanisms of fatigue and recovery in hamstring vs quadriceps muscles during whole-body soccer match-play is currently unknown. METHODS: Eleven male soccer players (18.7±1.6 years) from an elite French academy took part in this study and performed a simulated soccer match-play (2x45 min).  …”

Anderson, R., Rollo, I., Martin, D., Burden, R., Randell. R. K., Twist, C., Grazette, N., Moss, S. “… Although a range of methods have been proposed to assess ovulation day and subsequent MC variability, agreement between methods remains unknown. Hence, the first aim of this study was to compare three methods of determining ovulation: (1) positive urinary luteinising hormone (LH) test, (2) sustained rise in progesterone above critical difference, and (3) countback regression equation (CRE).  …”
