This study found a resistance training protocol reliable for assessing short-term exercise performance. The protocol effectively induces fatigue and may help evaluate interventions aimed at improving fatigue resistance.

Area of Science:

  • Exercise Physiology
  • Sports Science
  • Human Performance

Background:

  • Assessing short-term resistance exercise performance requires reliable protocols.
  • Understanding exercise-induced fatigue is crucial for training and rehabilitation.

Purpose of the Study:

  • To evaluate the reliability of a specific resistance exercise protocol.
  • To determine if the protocol can induce measurable fatigue.
  • To assess its utility in future performance research.

Main Methods:

  • Six male subjects performed leg extensions at 80% of 10 repetition maximum (RM).
  • The protocol involved 6 sets with 90-second passive recovery, exercising to fatigue in the final 3 sets.
  • Two experimental trials were conducted after a familiarization session.

Main Results:

  • A significant performance decline occurred from set 4 to sets 5 and 6, indicating induced fatigue.
  • High intraclass correlations (0.992-0.993) demonstrated excellent reliability.
  • Low coefficients of variation (2.7-7.1%) further supported the protocol's consistency.

Conclusions:

  • The tested resistance training protocol is highly reliable for assessing short-term performance.
  • The protocol effectively induces fatigue, making it suitable for research.
  • It can be a valuable tool for evaluating interventions targeting fatigue resistance.
