Abstract

Study Design: Systematic Literature Review Objective: 1) to identify the overall trends of association of isometric strength and dynamic activities 2) to summarize the findings of reported literature on the relationship of Isometric strength and dynamic performance. Background: Isometric Strength measures have been used for many years to predict dynamic performance but there are considerable controversies regarding the potential of isometric muscle assessments to predict dynamic performance. Although researches have been conducted to study the relationship, it is important that the current available literature be reviewed to summarize the findings for clinical use. Methods: A systematic review was conducted to identify the published studies that correlated the Isometric and dynamic variables. Studies were searched using electronic databases and the methodological quality of each study was assessed using the modified Downs and Black 13 point criteria. Results: Fifteen studies met the inclusion criteria. Marked difference in the methodology and variables used for isometric and dynamic activities were observed. Most studies correlated isometric strength assessments to dynamic activities or dynamic strength measurements. Discussion & Conclusion: Although there are conflicting opinions regarding the use of isometric measurements, most studies in our review report moderate to strong correlation between Isometric strength and dynamic performances specially those which involve large amounts of force and explosive power.
