Abstract
Some of the physiological changes associated with the taper and their relationship with athletic performance are known since 1960s. Since the 1980s numerous studies have examined various physiological responses associated with the cardiorespiratory, metabolic, hormonal, neuromuscular and immunological systems during the pre-event taper across a number of sports but there were not a clear results obtained. Recently, miRNAs have been shown to play an important role in the regulation of muscle development. miRNA-1 and miRNA-206 are expressed in cardiac and skeletal muscle and are transcriptionally regulated by the myogenic differentiation factors. Purpose of this study was to investigate miRNAs 1 & 206 in response to training handball program followed by tapering for 5 days. Results are compared to some physical and skills performances in fourteen handball female players constitute Helwan University handball team. Results showed significant increased levels in both miRNAs due to both of training program and tapering with improved performance in physical and skills properties. It is concluded that tapering enhance miRNAs 1 & 206 transcription that enhance muscle differentiations and proliferation leading to improved performance.
