The ability of an individual to move smoothly depends on his flexibility, an attribute that enhances both safety and optimal physical activity. Zachezewskil, (1987) has defined muscle flexibility as the ability of a muscle to lengthen, allowing one joint (or more than one joint in a series) to move through a range of motion (ROM). Muscle tightness is caused by a decrease in the ability of the muscle to deform, resulting in a decrease in the range of motion at the joint on which it acts. This is a limiting factor for optional physical performance. The hamstrings are examples of muscle groups that have a tendency to get shorten (Turneret al., 1988). Hamstring injuries are one of the most common sports injuries and are a leading cause of time away from sports and causes significant loss of training and competition time and significantly affects the quality of life of injured athletes. Hamstring muscle injury also has a high recurrence rate, which frustrates the injured athletes as well as the clinicians and the increases cost of the treatment (Kakarapathi & Gannamaneni, 2017). This study wants to determine the effectiveness of taping the sacroiliac joint in improving flexibility of the hamstring among varsity players. The objective of the researchers is to determine if the sacroiliac joint is taped in the position of anterior pelvic tilt, will it improve the flexibility of the hamstring. The researchers used an experimental type of research that aimed to determine the effectiveness of taping the sacroiliac joint in improving hamstring flexibility among varsity players. The sampling technique used was purposive sampling.
The respondents consists of 20 varsity basketball players, with 16 male and 4 female s whose age ranges from 17-22 years old with a mean value of 16.95 years old. A pre-test measurement was done as baseline measurement followed by application of the taping technique by the Certified Taping Practitioner. A total of 3 sessions was attended by the subjects including the baseline prior to application of tape. Subjects were assessed again using a goniometer and Passive Straight Leg Raise test by the same assessor after 24 hours with the tape on, another measurement were done after 48 hours with the tape on. Based on the findings of the researchers, measurements from pretest to post test 1 and 2 a p value of p<0.01 which is less than 0.05, indicating that there was a significant difference in the passive straight leg raise ROM among the respondents after application of sacroiliac joint taping technique. Therefore, based on the result of the study, it demonstrated that taping the sacroiliac joint was effective in improving hamstring flexibility among varsity players with tight hamstring.
