Abstract Background The U.S. Air Force physical fitness assessment (PFA) is used to determine the overall fitness of their personnel. It is currently unknown to what extent the PFA scores of Reserve Officers’ Training Corps (ROTC) cadets are affect

INTRODUCTION: Due to the standard collegiate academic calendar (two semesters), U.S. Air Force Reserve Officers Training Corps (ROTC) cadets have an approximate 3-mo break over the summer in which physical training (PT) is neither regulated nor requi

It is well known that muscle spindles have a monosynaptic, excitatory connection with α-motoneurons. However, the influence of muscle spindles on human motor unit behavior during maximal efforts remains untested. It has also been shown that muscle s
