Reliability of the assessment of peripheral fatigue induced in knee extensors by highintensity intermittent running exercise (HIE) was established in ten amateur soccer players (age: 18 ± 1, height: 178 ± 5 cm, weight: 68 ± 8 kg). METHODS: Transcutaneous electrical stimulations before and after HIE determined muscle contractile properties on three separate occasions (T1, T2 and T3), each separated by 7 days. RESULTS: No significant differences were noted for any of the parameters measured (P =0.101). The ICC values for peak torque (PT) varied from moderate to high, with the exception of PT at 10Hz calculated comparing T2 vs T1 (range PRE =0.780.92; POST =0.760.97). The ICC derived from PT percentage decrements data were all low, with the exception of PT decrements at 1 Hz calculated comparing T3 vs T2(ICC =0.85, moderate). The TE for all contractile parameters obtained using 1Hz and 100Hz electrical stimulations were below 10%, including some that demonstrated a TE lower than 5%. Muscle contractile properties determined using 10Hz stimulations showed a higher level of TE (range: 3.215.1%). Similar results were obtained for maximal rate of torque development and torque relaxation. CONCLUSION: From the results of this study it can be concluded that muscle contractile properties express a good level of reliability in baseline and postexercise measures following familiarization.

Abstract

Reliability of the assessment of peripheral fatigue induced in knee extensors by highintensity intermittent running exercise (HIE) was established in ten amateur soccer players (age: 18 ± 1, height: 178 ± 5 cm, weight: 68 ± 8 kg). METHODS: Transcutaneous electrical stimulations before and after HIE determined muscle contractile properties on three separate occasions (T1, T2 and T3), each separated by 7 days. RESULTS: No significant differences were noted for any of the parameters measured (P =0.101). The ICC values for peak torque (PT) varied from moderate to high, with the exception of PT at 10Hz calculated comparing T2 vs T1 (range PRE =0.780.92; POST =0.760.97). The ICC derived from PT percentage decrements data were all low, with the exception of PT decrements at 1 Hz calculated comparing T3 vs T2(ICC =0.85, moderate). The TE for all contractile parameters obtained using 1Hz and 100Hz electrical stimulations were below 10%, including some that demonstrated a TE lower than 5%. Muscle contractile properties determined using 10Hz stimulations showed a higher level of TE (range: 3.215.1%). Similar results were obtained for maximal rate of torque development and torque relaxation. CONCLUSION: From the results of this study it can be concluded that muscle contractile properties express a good level of reliability in baseline and postexercise measures following familiarization.
