Hypothesis
The decrease in muscle strength would be reduced if the subjects performed strength training in addition to the endurance training during immobilization periods.
Conclusion
The training programs during the immobilization period were effective in preventing a decline in muscle oxidative function, endurance, and strength.
Supporting Evidence
- Endurance training prevented declines in endurance performance and oxidative capacity.
- Strength training helped preserve grip strength during immobilization.
- Significant interactions were found in muscle oxygen consumption recovery and grip endurance.
Takeaway
Doing some exercises with your hands while your arm is in a cast can help keep your muscles strong and working well.
Methodology
Ten healthy adult men underwent non-dominant forearm immobilization for 21 days, with one group performing training exercises.
Limitations
The study did not measure skin-fold thickness, which could influence NIRS measurements.
Participant Demographics
Ten healthy adult men, mean age 22.8 years.
