OBJECTIVES To determine the relationship between maximum power relative to body weight (Pmax-rel) and the aging process, and to indicate the target values of improvement of motor function in Japanese individuals. METHODS In 410 physically active Japanese subjects (7-79 years) with no impairment of daily activities were performed counter-movement jumps. We evaluated the correlation between age...

PURPOSE To assess the relative role of handgrip strength (HGS), quadriceps muscle power (Pmax), and optimal shortening velocity (υopt) in maintaining functional abilities (FAs) in older adults living in a long-term care home over a 1-year follow-up. SUBJECTS AND METHODS Forty-one inactive older institutionalized adults aged 69.8±9.0 years participated in this study. HGS, Pmax, υopt, cognitive...

We give a proof that OCA holds in the Pmax extension of L(R). The proof is general enough to be adapted to most Pmax variations.

The study aimed to investigate the differences in the effects of 7-month training on aerobic and anaerobic capacity in tandem cycling athletes with and without visual impairment. In this study, Polish elite (n=13) and sub-elite (n=13) visually impaired (VI) (n=13; 40.8 ±12.8 years) and properly sighted (PS) (n=13; 36.7 ±12.2 years) tandem-cycling athletes participated voluntarily in 7-month rou...

In Maxwell electrostatics the electrostatic potential of a point charge is singular at position charge. this paper, nonsingular model for presented in presence momentum cutoff pmax based on one-parameter deformation Heisenberg algebra 2D-dimensional phase space. For pmax→∞, results paper reduce to ordinary

In this paper we analyze the cycle-to-cycle variations of maximum pressure pmax and peak pressure angle αpmax in a four-cylinder spark ignition engine. We examine the experimental time series of pmax and αpmax for three different spark advance angles. Using standard statistical techniques such as return maps and histograms we show that depending on the spark advance angle, there are significant...

Objective: Atrial fibrillation (AF), commonly observed in advanced ages, displays striking age dependent increase and increased P wave dispersion (PWD) has been shown to be a predictor of AF. In this study we sought to determine whether P wave duration and PWD increase with aging. Method and Results: Eighty-three elderly subjects (group-I mean age 75±8 years) and 40 healthy young subjects (grou...

In his book on Pmax [6], Woodin presents a collection of partial orders whose extensions satisfy strong club guessing principles on ω1. In this paper we employ one of the techniques from this book to produce Pmax variations which separate various club guessing principles. The principle (+) and its variants are weak guessing principles which were first considered by the second author [3] while s...

While there is a direct relationship between maximal anaerobic power (Pmax) and swimming performance, the relationship between upper and lower limbs with regard to Pmax and force-velocity (F-v) characteristics is not clear. The aim of the present study was to examine the effect of age and sex on the ratios of mechanical characteristics between upper and lower extremities of adolescent swimmers....
