Simulation of high flexion tasks such as squatting is hindered through invalid moment length estimation when using generic musculoskeletal (MSK) models. The purpose of this study was to examine the effect of wrapping surface (WS) at the knee and hip joints on the muscle moment arms calculated using a MSK model during squatting tasks. A generic full body model was modified by (1) increasing knee...

The purpose of this study was to determine if an appropriate drop jump height for female athletes could be determined from squat and/or power clean maximums. Thirteen female collegiate basketball or volleyball players had their appropriate drop jump height determined by both maximal jump height (MJH) and reactive strength index (RSI) methods. The two methods often determined different appropria...

The Functional Movement Screen(FMS) is a useful tool to assess functional abilities in a pre-participation screening. Its seven dynamic movement tests reveal shortcomings in stability and mobility and screen the whole body. However, the current test protocol delivers results that are subjective, qualitative and have to be manually processed. This article presents a semi-automatic system to over...

It is unclear if increases in 1 repetition maximum (1RM) in quarter squats result in higher gains compared with full depth squats in isometric force production and vertical jump performance. The aim of the research projects was to compare the effects of different squat variants on the development of 1RM and their transfer effects to Countermovement jump (CMJ) and squat jump (SJ) height, maximal...

This paper extends a new line of research on urban squatting that focuses on the role of the squatter organizer. The model replaces the benevolent organizer from previous studies with a collection of competing, rent-seeking squatter organizers, a structure that may offer a realistic picture of many cities in less-developed countries. In addition to delineating the structure of such a competitiv...
