Sports Dynamics and Biomechanics

are types of vertical jumps, and constitute the most useable tests for the assessment of the neuromuscular coordination of athletes (Claudino et al., 2017).In addition, CMJ is used for the assessment of the fitness level of injured athletes after rehabilitation periods, and for detecting their fitness to return to play (Clanton, Matheny, Jarvis, & Jeronimus, 2012;Henderson, Barnes, & Portas, 2010;Olsson et al., 2013).Forcetime (F-T) curve variables of CMJ are utilised to assess neuromuscular and biomechanical features related to lower extremity dynamics (Claudino et al., 2017;Kollias et al., 2001).Additionally, vertical jump tests are performed in accordance to various aims, such as the assessment of the developed force and power in elite athletes who participate regularly in competitions (Cormie, McGuigan, & Newton, 2010).McGinnis et al. (2016) have used CMJ to assess the effect of fatigue on performance.Olsson et al. (2013) showed that CMJ and other types of jumps could be used for the assessment and evaluation of athletes' performances, after Achilles tendon tears.Previous research studies have shown that CMJ has an appropriate validity for assessing explosive
