  • The Interactive Effect of exercise intensity and task difficulty on human cognitive processing.
    International Journal of Psychophysiology, 2007
    Co-Authors: Keita Kamijo, Yoshiaki Nishihira, Takuro Higashiura, Kazuo Kuroiwa
    Abstract:

    The Interactive Effect of exercise intensity and task difficulty on human cognitive processing was investigated using the P3 component of an event-related brain potential (ERP). Exercise intensity was established using Borg's rating of perceived exertion (RPE) scale, and task difficulty was manipulated using a modified flanker task comprised of incongruent and neutral trials. Twelve participants (22 to 30 y) performed the flanker task during a baseline session, and again after light (RPE: 11), moderate (RPE: 13), and hard (RPE: 15) cycling exercise. Results indicated that the P3 amplitude increases across task conditions following light and moderate cycling, but not during hard cycling, relative to baseline, suggesting that P3 amplitude may change in an inverted U fashion by as a result of acute exercise intensity. Additionally, the expected delay in P3 latency for incongruent relative to neutral trials was observed during the baseline condition. However, following acute exercise these task condition differences diminished across exercise intensities. Moreover, reaction times following all exercise conditions were shorter when compared to the baseline condition. These findings suggest that P3 latency is more sensitive to task difficulty manipulated by a flanker task than behavioral measures, and P3 latency during trials requiring greater executive control processes might be more sensitive to the Effects of acute exercise than tasks requiring minimal effort.

  • Interactive Effect of Rhizotrophic Microorganisms on Growth, Yield, and Nutrient Uptake of Wheat
    Journal of Plant Nutrition, 2005
    Co-Authors: Almas Zaidi, Saghir Khan
    Abstract:

    ABSTRACT The Interactive Effect of rhizotrophic microorganisms on growth, yield, and nutrient uptake of wheat (Triticum aestivum L.) was determined in a pot experiment using sterilized soil deficient in available phosphorus (P). Positive Effect on plant vigor, nutrient uptake, and yield in wheat plants was recorded in the treatment receiving mixed inoculum of nitrogen-fixing Azotobacter chroococcum + phosphate solubilizing microorganism (PSM) Pseudomonas striata + arbuscular mycorrhizal (AM) fungus Glomus fasciculatum. The available P status of the soil improved significantly (P ≤ 0.5) following triple inoculation with A. chroococcum, P. striata, and G. fasciculatum. The residual nitrogen (N) content of the soil did not change appreciably among the treatments. Addition of Penicillium variable to single- or double-inoculation treatments negatively affected the measured parameters. The population of A. chroococcum, PSM, percentage root infection, and spore density of the AM fungus in inoculated treatments i...

  • Interactive Effect of rhizotrophic microorganisms on yield and nutrient uptake of chickpea cicer arietinum l
    European Journal of Agronomy, 2003
    Co-Authors: Almas Zaidi, Md Saghir Khan
    Abstract:

    Abstract The Interactive Effect of rhizotrophic microorganisms on the yield and nutrient uptake of chickpea plants and soil was determined in a sandy clay loam soil, deficient in available phosphorus (P). Plant yield and nutrient uptake were significantly enhanced as a result of inoculation with Rhizobium sp. and phosphate solubilising microorganisms (PSM), Pseudomonas striata or Penicillium variable . Plant yield and nutrient uptake were further augmented by the addition of AM fungus, Glomus fasciculatum in the combined inoculation treatment with Rhizobium sp.+ P . striata . However, a negative Effect occurred on all the considered parameters when G. fasciculatum was added to the combination of Rhizobium sp. and P. variable . In addition, the available P status of the soil improved by the addition of P. striata with Rhizobium sp. and AM fungus. The nitrogen content of the soil did not show appreciable changes after the inoculation. The population of phosphate solubilising microorganism in combinations on root infections and spore density of the AM fungus in the soil showed increase between 45 and 90 days of plant growth.
