Dissertation submitted in partial compliance with the requirements for the Master's Degree in Technology: Chiropractic at Durban Institute of Technology, 2007. / Objectives The objectives were to compare the relative effect of manipulation and core rehabilitation in the treatment of acute mechanical lower back pain in athletes. Project Design: The study design was a randomized controlled parallel group trial. A quantitative study was performed, by making use of a pre à à à ¢ and post experimental investigation (Nansel et al. 1993 and Naidoo, 2002). Setting: Participants presenting with acute low back pain with an onset of 7 days or less, to the Chiropractic Day Clinic at the Durban University of Technology. Subjects: Thirty athletic participants, either male or female, between the ages of 18 and 45 years presented at the initial consultation which included participant screening and establishment of their suitability for the study. These were then divided into either group A (which received a manipulation) or group B (which received core exercises). Outcome measure: A correct contraction of the core stability muscles was maintained, with a decrease in pressure (in mm Hg) on a Pressure Biofeedback Unit, and an increase in length of time (in seconds). Results: It was found that there was no significant difference between the manipulation and the core rehabilitation groups. Although both groups showed v improvement with regards to their acute mechanical low back pain, the core rehabilitation group improved at a significantly faster rate than the manipulation group with regards to endurance on the stabilizer. Conclusions: Both treatments were equally beneficial for most of the quantitative outcomes measured in this study. However, for the outcome of time on the stabilizer, the core rehabilitation group improved at a significantly faster rate than the manipulation group (p=0.006).

2 pp. / To gain weight, athletes need to consume more calories than they use. This weight gain will include water, fat, and protein in muscle. To limit the amount of fat gain and increase muscle gains, athletes need to use effective exercise training and nutrition programs.

Older individuals are known to adopt a less efficient breathing strategy than young adults during exercise. Whether different strategies are adopted by young and master athletes matched for height, weight and training volume during incremental and constant running is unclear.  In the first part of this thesis, it was demonstrated that during an incremental run to exhaustion and an 8 minute constant intensity run at 90% maximal aerobic speed, master athletes regulate their breathing less efficiently than young athletes.  Major differences in breathing regulation were also observed within the young athletic group (between individuals and between tests) indicating a heterogeneity of response in this population that was, at least partly, linked to baseline expiratory flow rates. An original approach (<i>i.e. </i>using urinary levels of the lung specific protein CC16 to detect a possible disruption of the airway epithelium during exercise in young athletes) was used in the second part of the thesis.  In the first instance, an increase in urinary CC16 after a short period of hyperpnoea of dry air in all the individuals studied (<i>i.e.</i> trained and untrained subjects with and without asthma) was demonstrated.  By comparing the response of summer and winter athletes it was then established that the rise of CC16 post-challenge was independent from the usual environment in which athletes train.  Finally, it was shown that the rise of urinary CC16 is more severe after a short exercise bout performed in cold dry than hot humid air.  Together these results confirm that exercise-induced hyperventilation can have a noxious effect on the fragile airway epithelium of healthy young athletes.
