BACKGROUND We examined aerobic and anaerobic exercise energy expenditure and excess post-exercise oxygen consumption (EPOC) between a 250 Watt, 1-minute bout of cycling and uphill treadmill running. METHODS Fourteen active to well-trained subjects volunteered for the investigation (VO2 max: 57.0 +/- 12.9 ml x kg x min(-1) cycle; 59.3 +/- 13.7 ml x kg x min(-1) run; p = 0.44). Anaerobic energy...

In this paper, performance evaluation of high speed optical wireless communication has been observed. It has been observed that Q value lies in the range of 26 to 15 dB and 25 to 14dB in the transmission power (8dBm) and attenuation (23dB) at distance of 800m to 2000m in free space optical communication. Similarly BER lies in the range of 10 to 10 4 and 10 to 10 in the transmission power and at...

The capacity of animals to dissipate heat may constrain sustained energy intake during lactation. We examined these constraints at peak lactation in MF1 mice that had ad libitum access to food, or that had to run a pre-set target on running wheels to obtain ad libitum access to food. The voluntary distance run decreased sharply during pregnancy and peak lactation. When lactating females were pr...

Ten normal, non-asthmatic subjects performed an 18 min graduated exercise test on a static exercise bicycle on 3 separate days. They received either no medication, or propranolol 80 mg orally 2 h before, or ipratropium bromide 0.216 mg by inhalation 30 min before, the start of exercise. With no medication, transpulmonary index (TPI), a measure of airway resistance, fell linearly during exercise...

The position of the base station (BS) in wireless sensor networks (WSNs) has a significant impact on network lifetime. This paper suggests a mobile BS positioning algorithm for clusterbased WSNs, which considers both the location and the remaining energy level of the cluster heads in the network and evaluate the performance of the algorithm under different values of network sizes, including 100...

In each of two experiments, four groups of 10 female Scottish Blackface sheep grazed for 2 weeks at each of four space allowances, according to a Greco-Latin Square design. Space allowances were 80, 100, 133 or 200m(2) per head in Experiment 1 and 50, 67, 100 or 200m(2) per head in Experiment 2. Confounding of space allowance and grazing pressure was avoided by the use of a rotational grazing s...

In 1997 the author published an article on vertical full (and ground plane type half) wave loops for 80 meter DX. In that article it was noted that perpendicular (horizontal) polarization is the preferred polarization, particularly at low elevation angles, since horizontally polarized waves are hardly affected by the finite conductivity of the ground in front of the antenna. An exception when v...

The aim of present study was to investigate whether food restriction combined with exercise training could attenuate the oxidative stress and promote angiogenesis in a rat model of heart failure. 50 male wistar rats weighing 250-300 g were randomly divided into 5 groups including: 1) sham; they were fed ad libitum food, n=10. 2) Heart failure group; 3) Exercise group; they run on a treadmill 5 ...

BACKGROUND Optimal human function and performance through diet strategies are critical for everyone but especially for those involved in collegiate or professional athletics. Currently, individualized medicine (IM) is emerging as a more efficacious approach to health with emphasis on personalized diet strategies for the public and is common practice for elite athletes. One method for directing ...

We report the athletic, physiological and mitochondrial-related genomic data of an Israeli endurance runner. He is holding the Israeli record in 10000, 5000, 1500 and 800m run, along with being one of the best Israeli 400m runners. We tested the ACTN3 R577X, and six polymorphisms in the PPARGC1A-NRF-TFAM pathway genes. The case athlete was heterozygous for the ACTN3 R577X variation and had five...
