Abstract

Weightlifting performance is highly associated with maximum strength which depends frame of skeletal muscles composition. The purpose of the study was to find out relationship between anthropometric, body composition, lower body strength and weightlifting performance of junior weightlifters. To achieve the objective, fourteen (N=14) junior national level weightlifters were selected from Jaffna Central College, Sri Lanka, their age ranges were 17 years to 20 years. Participants weightlifting performances were measured from snatch (SN), clean jerk (CJ), bench press (BP), dead lift (DL) and squat (SQ) in various days. Gold standard of anthropometric measurements were conducted to measure weight (WE) in kilogram, height (HE) in meter, shoulder circumference (SHC) and chest circumference (CHC) in centimeter. Lean body mass (LBM) and body mass index (BMI) has been considered a body composition variables (BC). LBM was determined based on Boer formula (1984) and BMI was calculated according to standard BMI formula. Lower body strength (LBS) has been assessed based on standing broad jump (SBJ) recorded in meter and vertical jump (VEJ) recorded in centimeter. Results revealed SN has been correlated with HE (r=0.554), LBM (r=0.586) and SBJ (r=0.567) as well as CJ also with HE (r=0.584), LBM (r=0.593) and SBJ (r=0.591). BP has correlated with HE (r=0.552), WE (r=0.535), LBM (r=0.607) and SBJ (r=0.520). DL has been correlated with SBJ (r=0.689) and VEJ(r=0.611). SQ was correlated with WE(r=0.575), LBM(r=0.605) and SHC (r=0.565). Study concluded that a selected anthropometric measurement such as lower body strength & body composition has been correlated with weightlifting performance.
