Countermovement jump (CMJ) assessment is a commonly used test in strength and conditioning to inform the training process. For example, it can be used to explore neuromuscular function, assess the response to training interventions, monitor athletes’ performance readiness through a competitive

jump is the exercise modality where the highest anaerobic power output values are obtained, 6 although a direct relationship between jump height and power output is confounded by body mass, push-off distance, optimal loading, and individual force–velocity profile. 7 The countermovement jump (CMJ) test
Effects of Task Constraints on Countermovement Jump Kinematics Following a Short-Term Training

kinematic variables of movement ( Bartlett, 2014 ; Newell, 1985 ). The phenomenon of motor learning development due to implementing movement constraint could be examined in fundamental or advanced skills ( Davids et al., 2008 ). For instance, this phenomenon may be tested for the countermovement jump (CMJ
Effects of Caffeine on Countermovement-Jump Performance Variables in Elite Male Volleyball Players

significant jump-performance improvements in elite female players. 18 To test jump ability, the countermovement jump (CMJ) is commonly used since it replicates jumps performed during a real game. Furthermore, the CMJ has been shown to be one of the best tests to detect neuromuscular fatigue due to its high

, proprioception, power, and pain. 2 , 3 , 5 , 6 Some have suggested that the effects of KT would be more beneficial if they also existed in functional situations, high-load tasks, or fatiguing circumstances. 5 – 7 A popular use of KT is in sports activities, such as countermovement jump (CMJ). 5 , 6 , 8 – 11
Effects of Weighted Vest Loading During Daily Living Activities on Countermovement Jump and Sprint Performance

Wearing a weighted vest (WV) during daily living activities and training (WVDT), 1 – 3 or during daily living only, 4 – 6 is one form of external loading used to enhance countermovement jump (CMJ) and sprinting performance. The theoretical benefits of WVDT were supported in a seminal
Countermovement Jump Recovery in Professional Soccer Players Using an Inertial Sensor

Countermovement jump (CMJ) tests are commonly used to assess recovery of muscle function following strenuous exercise. Impairments in CMJ have been demonstrated on the days following various forms of exercise including drop jump protocols, 1 – 3 repeated sprint, and simulated field sport tests 4

quasi-linear force–velocity relationship is reported, 4 with empirical evidence supporting a load equal to body mass as the optimal load to maximize system power during a countermovement jump (CMJ). 5 – 7 Long-term specialized training can have a profound influence on a muscle’s contractile profile, 8
Monitoring Changes in Lower-Limb Strength and Power in Elite Athletes With the Countermovement-Jump and Keiser Leg-Press Tests
