Effect of intermittent normobaric hypoxic exposure at rest on haematological, physiological, and performance parameters in multi-sport athletes

The aim of this study was to determine whether 3 weeks of intermittent normobaric hypoxic exposure at rest was able to elicit changes that would benefit multi-sport athletes. Twenty-two multi-sport athletes of mixed ability were exposed to either a normobaric hypoxic gas (intermittent hypoxic training group) or a placebo gas containing normal room air (placebo group). The participants breathed the gas mixtures in 5-min intervals interspersed with 5-min recovery periods of normal room air for a total of 90 min per day, 5 days per week, over a 3-week period. The oxygen in the hypoxic gas decreased from 13% in week 1 to 10% by week 3. The training and placebo groups underwent a total of four performance tests, including a familiarization and baseline trial before the intervention, followed by trials at 2 and 17 days after the intervention. Time to complete the 3-km run decreased by 1.7%[95% confidence interval (CI) = -0.6 - 3.9%] 2 days after, and by 2.3% (CI = 0.25 - 4.4%) 17 days after, the last hypoxic episode in the training relative to the placebo group. Substantial changes in the training relative to the placebo group also included increased reticulocyte count 2 days (23.5%; CI =-1.9 to 44.9%) and 12 days (14.6%; CI = -7.1 to 36.4%) post-exposure. The effect of intermittent hypoxic training on 3-km performance found in this study is likely to be beneficial, which suggests non-elite multi-sport athletes should expect such training to enhance performance.     

The book collections of British university libraries an American reaction

This study summarizes a survey conducted to discover the extent to which professional librarians in Nigerian university libraries have achieved academic/faculty status. The survey revealed that: (1) almost all professional librarians (16 or 80%) in Nigerian universities have full faculty status, coupled with mandatory research and publication for promotion, in 17 (85%) of the libraries; (2) publications in subject-fields and in library/information science carry equal ratings; and (3) academic librarians in Nigeria are entitled to the same rights, privileges and responsibilities as their teaching counterparts. This paper urges the Nigerian Library Association and the Committee of University Librarians to set standards for the attainment of faculty/academic status for professional librarians in Nigerian universities and colleges.     

Evaluating the future value of educational interventions in a health care setting

Program evaluation is intended to systematically determine the merit and worth of a program. We broadly define merit and worth to include economic perspectives obtained through the analysis of the finances of a program—both the costs and the benefits. A study reported here addressed the cost and benefit of investing in an educational intervention to change and improve processes in a health care setting. The potential economic impact of a training intervention intended to improve the uptake of a new purchasing process was evaluated. The study illustrates economic evaluation that anticipates the future value of educational interventions, a prospective view.
