PAP (post-activation potentiation) or PAPE (post-activation performance enhancement -as shown here) is a really useful physiologic phenomenon This is an extremely useful physiologic phenomenon that can: 1. Enhance power based rehab & performance 2. Potentially overcome inhibition preventing quality muscle activation during rehab PAP refers to: The influence of...

Normalise RDL as a main movement. The Romanian Deadlift (RDL) or Heavy Barbell Hip Hinge is a powerhouse exercise that has gained a lot of popularity among strength and conditioning coaches, powerlifters, and bodybuilders alike. This movement is often called an “athlete maker" in my mind due to its ability to build strength, muscle mass, and athleticism in both men and women. One of the primary reasons why the RDL is so effective for athletes is because it is triphasic, for the uninitiated meaning it involves three distinct phases of muscle action: eccentric, isometric, and concentric. During the eccentric phase, the lifter is lowering the weight, which creates tension and stress on the muscles, leading to greater muscle damage and adaptation. The isometric phase occurs when the lifter pauses at the bottom of the lift, holding the weight in a static position, which increases the time under tension and helps to build strength and stability. Finally, during the concentric phase, the lifter raises the weight, activating the muscles in a way that promotes greater hypertrophy. Compared to a traditional deadlift off the floor, the RDL places a greater emphasis on the posterior chain, specifically the proximal hamstring, glutes, and erector spinae muscles. The lift also engages the distal hamstring muscles in a nearly fully extended position, promoting greater muscle activation and strengthening. The RDL is an excellent way to develop strength and hypertrophy in these muscle groups, leading to improved overall athletic performance, including greater power, speed, and explosiveness. Given the numerous benefits of the RDL, it should be a main movement in any training program that aims to improve strength, muscle mass, and overall athletic performance. Incorporating heavy barbell hip hinge movements, such as the RDL, into your training regimen can help to promote better posture, improved mobility, and greater overall strength and athleticism. So, whether you are a powerlifter, bodybuilder, or athlete, consider adding the RDL to your training program to take your strength and athleticism to the next level.

Cormack et al. observed altered flight time to contraction time ratio up to 2 days after elite competition “despite little changes in jump height performance” Different movement solutions occur to maintain a desired “performance” metric such as jump height or power output Legg et al. suggested that altering CMJ mechanics assisted with maintenance of jump height while in a fatigued state, with changes in dip magnitude observed midseason despite no change in jump height. 2️⃣RSI-mod as an alternative variable ?? CMJ height alone may not always discriminate between rugby league cohorts, emphasizing the requirement for the associated underpinning force-time variables [to indicate jump ‘strategy’], or RSImod at the very least McMahon et al. reported that a group of combined professional senior SL and RLC rugby league players who performed the CMJ with a “higher RSImod” demonstrated higher force, velocity and thus power outputs. 3️⃣Sensitive to change of different metrics , Jump Height 🆚 RSI-mod? CMJ height was not sensitive to change in neuromuscular status of elite Australian Rules Football athletes pre- to post-match, from 48-hours pre- to 48-hours post-match 📌Conclusions - RSImod or FT:CT may prove more useful overall as an indicator of readiness, slow SSC activity, and neuromuscular fatigue as they impact the coordinative strategy and jumping performance. - A decline of 8% in FT:CT or RSImod would indicate a change requiring intervention as at this level of neuromuscular fatigue there are considerable changes to performance 📚 📕Hughes, S., Warmenhoven, J., Haff, G.
