ECCENTRIC EXERCISE EFFECT (EET) ON PATELLAR TENDINOPATHY (PT): LITERATURE REVIEW

Abstract

Introduction: Patellar Tendinopathy (PT), also known as jumpers knee, is a soft tissue injury that commonly affects athletes who participate in sports that involve running and jumping. The treatments that can be done can be conservative and operative. In this case, operative means a way of surgery while conservative is by doing exercises. Some experts say that eccentric exercise (EET) is the best exercise for patellar tendinopathy.

Objective: To find out and conduct observations about the effectiveness of eccentric exercise training, particularly in cases of patellar tendinopathy, using existing scientific evidence.

Method: This literature review was based on journals with similar characteristics, such as Randomized Control Trials (RCT), controlled meta-analysis, and Randomized Studies. PubMed, ScienceDirect, ResearchGate, Elsavier, and J SportMed databases were searched for data sources. Patellar Tendinopathy, Eccentric Exercise, Eccentric Therapy, Jumpers Knee, Patellar Tendon, Chronic Patellar Tendinitis were some of the keywords used to find data sources. The following were the inclusion criteria: Data sources ranged from 2008 to 2020, respondents were male and female, the data source was related to PT, and the data source was in English. The exclusion criteria for this article were that the respondent's age wass less than 18 years or greater than 65 years, that the number of respondents was less than 30 participants, and that the article had no relationship with EET or PT.

Conclusion: EET increases the patellar tendon's resistance to tension and causes collagen fibers in the tendon to lengthen. EET promotes the formation of tendon collagen fibers, increases remodeling, and requires less oxygen consumption.
