Introduction: accentuated eccentric loading (AEL) training is a strength training novel methodology aimed to generate a potentiation over the exercise concentric phase. However, their effects are still quite unclear.
Objective: this review aimed to analyze the accentuated eccentric loading training over the concentric phase strength, velocity and power variables in traditional resistance exercises.
Methodology: a systematic search of science literature was carried out in different databases. Thirteen studies were included following established inclusion criteria. Studies quality was assessed following the STROBE scale.
Results: the mean rating was 15.8 points. Results change depending on the protocol and exercise performed.
Discussion: strength was the least studied variable and, in general, accentuated eccentric loading training improved the concentric phase. However, some studies did not appreciate this improvement. Compared to upper-limb resistance exercises, velocity and power variables were enhanced through AEL training in lower-limb resistance exercises. Nevertheless, some outcomes indicate that certain protocol variables may negatively impact the exercise concentric phase.
Conclusions: even though some studies show a potentiation effect with an overload during the eccentric phase, future research should analyze the role of different variables in AEL training protocols.
