Pull-ups at PS 25

Kinematic and electromyographic comparisons between chin-ups and lat-pull down exercises.

The purpose of this study was to compare kinematics and muscle activity between chin-ups and lat-pull down exercises and between muscle groups during the two exercises. Normalized electromyography (EMG) of biceps brachii (BB), triceps brachii (TB), pectoralis major (PM), latissimus dorsi (LD), rectus abdominus (RA), and erector spinae (ES) and kinematics of back, shoulder, and seventh cervical ...

Effect of Magnesium Carbonate Use on Repeated Open-Handed and Pinch Grip Weight-Assisted Pull-Ups

The purpose was to determine if pull-up performance was affected by the use of chalk (100% magnesium carbonate) during open-handed and pinch grip weight-assisted pull-ups (WAPU) in recreationally-trained rock climbers. Furthermore, the reliability of open-handed and pinch grip WAPU was also investigated. Recreationally-active volunteers (n = 9) completed six counterbalanced trials. Participants...

A 372 ps 64-bit adder using fast pull-up logic in 0.18µm CMOS

This paper presents a 372ps 64-bit adder using Fast Pull-up Logic (FPL) in 0.18 μm CMOS technology. Fast Pullup Logic is devised and applied to decrease pull-up time which is critical in domino-static adder. The implemented adder measures the worst case delay of 372ps. The adder has a modified tree architecture using Load Distribution Method and has 6 logic stages.

Pull-Ups, Push-Downs, and Passing It Around - Exercises in Functional Incrementalization

Programs in functional programming languages with algebraic datatypes are often datatype-centric and use folds or fold-like functions. Incrementalization of such a program can significantly improve its performance. Functional incrementalization separates the recursion from the calculation and significantly reduces redundant computation. In this paper, we motivate incrementalization with a simpl...
