Comparison between Isoinertial Training and Classical Training in Junior Athletes: Analysis of Hip Extension Test Results

This study compared the performance effects of isoinertial and traditional resistance training in junior athletes (U16), with a focus on hip extension test outcomes. The Exxentric kBox 4 Pro device and kMeter application were used to accurately monitor exercise execution and collect performance data. Twelve athletes (8 males, 4 females, aged 14.5±0.7 years) participated in hip extension assessments. Results indicated a significant increase in Mean Strength (N), from 171.75 (SD=65.08) to 259.75 (SD=86.07). A paired t-test showed a significant difference (d=1.44), suggesting the training intervention effectively enhanced strength in junior athletes, supporting its potential for youth athletic development.
