BACKGROUND The purpose of this study was to investigate the lifting characteristics of elders with functional limitations using burden lifting smoothness, trunk angular momentum, and back and hip torque, and to correlate these characteristics with strength and functional measures. METHODS Thirty elders (65-89 years old) consented to biomechanical analysis of lifting, gait, and chair rise, and...

Resistance (muscle strengthening) exercise is a key component of exercise recommendations for weight control yet very little is known about the effects of resistance exercise on appetite. We investigated the effects of resistance and aerobic exercise on hunger and circulating levels of the gut hormones acylated ghrelin and peptide YY (PYY). Eleven healthy male students: age 21.1 ± 0.3 y, body m...

let $m$ be a right module over a ring $r$, $tau_m$ a preradical on $sigma[m]$, and$ninsigma[m]$. in this note we show that if $n_1, n_2in sigma[m]$ are two$tau_m$-lifting modules such that $n_i$ is $n_j$-projective ($i,j=1,2$), then $n=n_1oplusn_2$ is $tau_m$-lifting. we investigate when homomorphic image of a $tau_m$-lifting moduleis $tau_m$-lifting.

BACKGROUND Previous studies have shown changes in low back muscle oxygenation after static muscle contractions or short-term dynamic lifting exertions. The aim of this study was to document the changes in low back muscle oxygenation during prolonged lifting activity over an entire workday as of function of work experience and lift frequency. METHODS Four novice and six experienced subjects pa...

Nonplanar lifting surfaces can lower the induced drag relative to planar surfaces by redistributing vorticity.Other sources of drag, such as viscous drag, as well as nonaerodynamic considerations, such as structural weight, also play an important role in assessing the overall efficiency of such lifting surfaces. In this paperwe solve a series of problems tofindoptimal nonplanar lifting surfaces...

objective(s) the purpose of the present study was to evaluate the effect of ramadan fasting and weight-lifting training on plasma volume, glucose, and lipids profile of male weight-lifter. materials and methods forty male weight-lifters were recruited and divided into 4 groups (n=10 each) and as the following groups: control (c), fasting (f), training (t) and fasting-training (f-t). the t and f...
