In the present study, we measured muscle endurance by completion of time to exhaustion tests where the subject has to maintain a fix workload for as long as possible. All time to exhaustion tests lasted less than ten minutes, confirming that OLDE was performed at high intensity. The duration of the time to exhaustion tests in the present study is in accordance with previous studies using the same exercise on a different ergometer [11, 17, 18]. Relative reliability refers to the degree to which individuals maintain their position in a sample with repeated measurements . The ICC value of 0.795 can be interpreted as a questionable reliability (ICC < 0.8), close to the threshold for good reliability (0.8 < ICC < 0.9) . However, as no consensus really exists on threshold to interpret ICC results , the practical significance of its value has to be determined with caution by the readers according to their future use of the present protocol. Absolute reliability refers to the degree to which repeated measurements vary for individuals . Traditionally, time to exhaustion tests are known to present a greater CV (CV > 10%) than time trials (i.e. subjects has to perform the greater amount of work possible in a fixed time/distance; CV < 5%) . Interestingly, in our study the CV is below 10%, confirming the great reliability of our novel high intensity OLDE protocol to measure muscle endurance, this despite the small sample size, chosen to be in accordance with previously published studies using the same protocol [8, 11, 17]. This great reliability is confirmed by the typical error of measurement value of 0.30 min, corresponding to 5% of the averaged performance value. Finally, as the typical error of measurement value was slightly above the smallest worthwhile change calculated (0.28 min), it is unlikely that our novel high intensity OLDE protocol can be used to detect small differences in performance.
The daily practice of the mind–body exercises took only a few minutes, to blend in with modern life rather than to dominate it. The exercises could be performed in private with no competitive, commercial, or political emphasis or personal ignominy. The MMB pioneers were against unnatural purpose-made exercise machinery, which was viewed as unnecessary and even dangerous. An exception was Pilates and his equipment. However, the revolutionary devices were designed (and succeeded) to improve the effect of Contrology exercises and philosophy, and to enhance the method’s natural experience and acceptance.
They’re fun and easy to do: Keep your upper body facing forward while your lower body moves; start with 10 swivels to the right, then 10 to the left. Then do 9 swivels to the right, 9 to the left, then 8 right 8 left, and so on down to one. As each set has your upper body twisting faster and faster, you should feel your abdominal muscles burning and your hips getting loose.
