Understanding the key phases of the countermovement jump force-time curve
TL;DR: Six key phases of the countermovement jump (CMJ) can be derived from force-time records to facilitate researchers’ and practitioners’ understanding and application to their own practice.
The Effect of Nordic Hamstring Exercise Intervention Volume on Eccentric Strength and Muscle Architecture Adaptations: A Systematic Review and Meta-analyses

TL;DR: Reducing NHE volume prescription does not negatively affect adaptations in eccentric strength and muscle architecture when compared with high dose interventions, and suggest that lower volumes of NHE may be more appropriate for athletes, with an aim to increase intervention compliance, potentially reducing the risk of HSI.
Countermovement-Jump-Phase Characteristics of Senior and Academy Rugby League Players
TL;DR: The CMJ distinguished between senior and academy RL players, with seniors demonstrating greater JH through applying a larger C-IMP and thus achieving greater velocity throughout the majority of the concentric phase and at takeoff.
Influence of the Reactive Strength Index Modified on Force– and Power–Time Curves
TL;DR: Athletes who perform the CMJ with a high RSImod, as achieved by high jumps with a short TTT, demonstrate superior force, power, velocity, and impulse during both the eccentric and concentric phases of the jump.

Determination of Optimal Loading During the Power Clean, in Collegiate Athletes
TL;DR: When training to maximize force and power, it may be advantageous to use loads equivalent to 60–80% of the 1RM, in collegiate level athletes.
