The present study aims to investigate the alteration in temporal patterns of lipid peroxidation products and antioxidants disturbed sleep in sprinters around 20 sprinters as subjects of same age group (18 to 25) were selected Ten sprinters were kept as control group (Group I) and 10 sprinters were allowed for a (24 hrs) disturbed sleep (Group II). At the end of experimental period of one night. Minimal amounts (5ml) of the blood were collected at 4 hrs time intervals (00:00, 04:00, 08:00, 12:00, 16:00, 20:00 hrs). The selected biochemical variables adopted to assay was tested. The values obtained were plotted against different time period in ‘cosinorwin’ programme. The characteristics of temporal patterns such as acrophase, amplitude, mesor, r- values and P-value were also obtained from “cosinorwin” software programme. The characteristics of the temporal patterns of acrophase, amplitude, mesor and r-value of all parameters studied were found to be desynchronized in group II which may be due to altered sleep patterns.
