The study investigated effects of extended knee sit-up on the strength of abdominal muscles of female secondary school students in Anambra East local government area. Three research questions and three null hypotheses guided the study. The design used in the study was true experimental design which utilized the pre-test post-test control group design. The population consisted of 1,294 female secondary school students in Anambra East Local Government Area of Anambra State. With purposive sampling technique three secondary schools were selected for the study. Using simple random sampling, 180 female students, from JS1 – SS3 were selected from the three schools. The experimental group consisted of 90 students while the control group also consisted of 90 students. Data were collected with a battery of tests similar to that advocated by Eurofit Fitness testing battery (1997). Tests used for the study were flexed knee sit- up for pre-test and post-test and extended knee sit-up for training. The control group did not receive any training while experimental group was trained for four weeks and data were analyzed using mean scores for the three research questions. Analysis of co-variance (ANCOVA) was used to test the hypotheses at 0.05 level of significance. Major findings indicated that the subjects who received training in extended knee sit-up performed significantly better than the control group who were not trained. There was also a significant difference in the mean score of those students who were trained and those not trained. Based on these findings, one of the educational implications was that the study provided the games mistresses and masters, coaches and physical educators opportunity to create awareness of the importance of exercise especially sit-up exercise on the abdominal muscles. One of the recommendations was that extended knee sit-up exercise should be used for screening purposes in the selection of athletes especially activities requiring strength of the abdominal muscles.
