| Abstract | Numerous studies have shown that stretching routines can induce strength and force deficits, although the amount of stretching needed to cause these deficits remains unclear. Therefore, the purpose of the study was to examine the relationship between varying amounts of acute static stretching on jumping performance. By systematically increasing the amount of stretching, possible differences in jump height may be discovered, defining a line where acute static stretching becomes detrimental to performance. Ten collegiate athletes and 10 recreational athletes completed 3 different stretching treatments and 1 control treatment on different days in a within-treatment design. Stretching treatments consisted of 2, 4, or 6 sets of stretches, with each stretch held for 15 seconds with a 15-second rest. Stretches were done to the quadriceps, hamstrings, and plantar flexors. Upon arrival, each subject performed a 5-minute warm-up on a stationary upright cycle. After a brief rest period, participants performed 3 trials of a vertical jump test, followed by one of the treatment protocols. After another rest period, a second set of vertical jump trials was performed. Post-6 sets was significantly lower than Pre-6 sets (p < or = 0.05). Additionally, Post-6 sets was significantly lower than Pre-4 sets, Pre-2 sets, and Pre-control (p < or = 0.05). No other conditions were significantly different. In conclusion, 6 sets of stretches, or 90 seconds per muscle group, should not be performed before power activities such as jumping where optimal performance is desired. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
