Chelatococcus daeguensis TAD1 is a themophilic bacterium isolated from a biotrickling filter used to treat NOx in Ruiming Power Plant, located in Guangzhou, China, which shows an excellent aerobic denitrification activity at high temperature. The complete genome sequence of this strain was reported in the present study. Genes related to the aerobic denitrification were identified through whole ...

A link between lactate and muscular exercise was seen already more than 200 years ago. The blood lactate concentration (BLC) is sensitive to changes in exercise intensity and duration. Multiple BLC threshold concepts define different points on the BLC power curve during various tests with increasing power (INCP). The INCP test results are affected by the increase in power over time. The maximal...

Purpose: It has been established that physical exercise generally improves the physical performance of older people. This finding has led to an increase in studies into the most efficient forms of exercise. The aim of this study was to compare the efficiency of three types of exercise: aerobic, strength and muscle power, in improving the functional capacity of older people. Methods: A study was...

Developing vertebrates increase both their locomotory power output and endurance due to ontogenetic improvements in anaerobic and aerobic metabolic capacities. Do similar patterns hold for insect locomotion, or do longer tracheal lengths create problems for oxygen delivery in older animals? We forced developing American locust grasshoppers (Schistocerca americana) to jump repeatedly and examine...

Background—Practising the martial art of taekwon-do (TKD) has been proposed to have beneficial eVects on cardiovascular fitness as well as general physical ability. Furthermore, TKD masters and participants have promoted TKD as a total fitness programme. Research studies substantiating this, however, seem to be lacking, perhaps because TKD is recognised more as a method of self defence than a f...

OBJECTIVES To evaluate weighted stair climbing exercise (SCE) as a means of increasing lower extremity muscle power in mobility-limited older people. DESIGN Single-blinded, randomized controlled pilot study. SETTING Human physiology laboratory of a metropolitan university. PARTICIPANTS Forty-five community-dwelling people aged 65 and older who had baseline mobility limitations manifested ...

The aim of the study was to examine the order of testing sequence on a child's ability to achieve maximal anaerobic and aerobic power. Thirty-two children (20 females, 12 males) between 7 - 11 years of age participated in this study. All subjects were tested on three separate occasions as follows: anaerobic power session - Wingate Anaerobic Test (WAnT) only; aerobic power session - maximal oxyg...

OBJECTIVES To determine the power-duration relationship in upper limb exercises and to investigate the relationships between parameters derived from this function with physiological indicators of aerobic fitness. METHODS Ten healthy men (26.2 ± 2.3 years, 75.0 ± 11.8 kg, 178.2 ± 11.5 cm and 15.0 ± 5.7% body fat) performed a ramped test on an arm cycle ergometer with increments of 20 W/min. Su...
