Introduction Plyometrics, also known as jump training or plyos, are exercises in which muscles exert maximum force in short intervals of time, with the goal of increasing power (speed-strength). This training focuses on learning to move from a muscle extension to a contraction in a rapid or “explosive” manner, such as in specialised repeated jumping.… Read More
Research Paper Title Five-meter rope-climbing: a commando-specific power test of the upper limbs. Background The purpose of this study was to examine the concurrent validity and absolute and relative reliabilities of a commando-specific power test. The participants included 21 anti-terrorism commandos. Methods All participants were assessed on a 5-m rope-climbing test (RCT) and the following… Read More
Research Paper Title What determines the metabolic cost of human running across a wide range of velocities? Background The ‘cost of generating force’ hypothesis proposes that the metabolic rate during running is determined by the rate of muscle force development (1/tc, where tc=contact time) and the volume of active leg muscle. A previous study assumed… Read More
Research Paper Title The Effect of Variation of Plyometric Push-Ups on Force-Application Kinetics and Perception of Intensity. Background To examine differences between ground-reaction-force (GRF)-based parameters collected from 5 types of plyometric push-ups. Between-trials reliability and the relationships between parameters were also assessed. Methods Thirty-seven highly active commando soldiers performed 3 trials of 5 variations of… Read More
Research Paper Title Soft, Stretchable, High Power Density Electronic Skin-based Biofuel Cells for Scavenging Energy from Human Sweat. Abstract This article describes the fabrication, characterisation, and real-life application of a soft, stretchable electronic-skin-based biofuel cell (E-BFC) that exhibits an open circuit voltage of 0.5 V and a power density of nearly 1.2 mW cm−2 at… Read More
“A muscle’s strength is proportional to its cross-sectional area, and an animal’s mass is proportional to its volume. The volume of an animal decreases more sharply than the muscle cross-sectional area as the animal under consideration gets smaller, so a mosquito is “stronger”than the much larger vulture and can take on a greater pro rata load. This also explains why other insects,… Read More
Research Paper Title Correlations between Physical Fitness Tests & Performance of Military Tasks – A Systematic Review & Meta-Analyses. Purpose To help evaluate the Army Physical Fitness Test (APFT) and ensure a future test is associated with Soldiers’ performance of common physical job requirements, the USAPHC applied a Systematic Review (SR) methodology to identify and synthesize published… Read More
