A catio can be a very simple mesh box that is attached to the outside of a window for a cat to sit in, a home-made concoction of PVC pipe and mesh, or a full-blast home addition with permanent walls and a roof, and everything in between.
1-RM Tests (Repetition maximum tests). purpose: to measure maximum strength of various muscle and muscle group s. procedure: One repetition maximum tests (1-RM) is a popular method of measuring isotonic muscle strength.
The higher the number of repetitions you can actually perform with the chosen weight, the larger the error in the estimate of your 1-RM. 1-RM = (weight lifted)/[1.0278 â (repetitions x 0.0278)]. From: Brzycki, M. (1993). Strength testing-Predicting a one-rep max from a reps-to-fatigue.Journal of Physical Education, Recreation and Dance 64 (1) , 88-90. This relationship is based on the relatively linear relationship between repetition maximal scores and the percentage of the 1-RM. properly conducted maximum strength test will however be more accurate than the predicted strength from an equation. Endurance versus Strength The correlation between absolute strength and endurance has been reported to exceed 0.90 (de Vries, 1980; Invergo et. al., 1991).
