    Correlates of cardiorespiratory fitness and gait parameters in young undergraduate subjects
    (U. P., 2010) Azeez, T. O.; Lamina, S.; Iwuji, S. C.
    Physiological studies of healthy individuals suggested that the pattern of walking influenced the oxygen cost of walking in a given distance. It has also been observed that in pathological states, shorter and frequent steps are common and that this inefficient gait might contribute to exercise limitation. The purpose of the present study was therefore to investigate the corelates of cardiovascular fitness and gait parameters in young undergraduate students. A cross sectional independent group design was used in data collection. Forty subjects with age ranged between 20 and 30 years participated in the study. Subjects’ cardiorespiratory fitness was assessed using the 1.4 miles run; subjects were group into cardiorespiratory fitness category of high and low. Gait parameters (cadence [CD], step time [ST] & gait speed [GS]) were assessed using the paper-and-pencil method. Student t test and Pearson correlation test were used in data analysis. Findings indicates significant increase in the high fit group over low fit group in CD, ST and GS at p<.05. There was a significant positive and negative correlation between VO2max and gait variables respectively: GS (.465), CD (.555) and ST (-.580) at p<.01. The present study concluded that cardiovascular fitness could be a positive factor/marker of qualitative pattern of walking in normal young adult. Future studies investigating the effect of physical training on pattern of walking in the healthy, chronic diseases and the disables are recommended.

    Ergogenic controversies of socio-cultural African herbs: A review study on khat (CATHA EDULIS) and kolanut (Cola Spp)
    (U. P., 2010) Lamina, S.; Azeez, T. O.; Subramanian, M.; Ayana, A. M.
    Khat and kola nut, are highly controversial ergogenic herbs indigenous to Africa and in the countries around the Red Sea. The spectrum of khat actions has been postulated to lie between amphetamines and caffeine while kola nut active chemical is caffeine. Therefore, khat and kola nuts and their principal active constituents (cathinone, cathine and caffeine respectively) are categorized as stimulants. The chewing of khat leaves and kola nuts has a deep rooted religious and socio- cultural tradition in Africa. Ironically, the World Antidoping Agency and the International Olympic Committee have placed a limit to cathine usage in sports. Caffeine, though not presently in the list of banned substances, but was previously banned, unbanned and restricted before 2004. Reasons for the partial ban and unban of cathine and caffeine respectively seem unclear and ambiguous. It is also confusing and worrisome if, the ethical line of cheating in sport is being scrutinized more carefully, or weather a cultural incident of khat and kola nut chewing is being handled appropriately. Before a conclusive statement could be made on the ergogenic status of both herbs, there is a need for joint extensive studies and international conference of stakeholders.

    Exercise and pregnancy: A review study
    (U. P., 2010) Lamina, S.; Musa, D. I.; Hanif, S.; Azeez, T. O.
    In recent times, researchers, exercise advocates and other professional experts in women’s health are agitating for women participation in exercise programme. Reasons for this advocacy might not be unconnected to the fact that the benefits of exercise for women far outweigh the complications particularly in pregnancy. This paper review significance of exercises during pregnancy. The review revealed that it is unrealistic for pregnant women to participate in vigorous physical activity, but could benefit from antenatal physiotherapy. It is also apparent that female athletes tend to have fever pregnancy and child birth related complications than do normal non athletic women. This is suggestive that women should be physically active but pregnant women continue to participate in activities which they are familiar with, while regular participation of women of reproductive age in exercise and sports is highly encouraged.
