Time-Course of Changes in Physiological, Psychological, and Performance Markers following a Functional-Fitness Competition.

Functional Fitness Training (FFT) programs are characterized by utilizing a high volume of training and using a variety of high intensity exercises.

Resistance Exercise Counteracts Tumor Growth in Two Carcinoma Rodent Models.

Purpose: Although resistance exercise (RE) is now recognized as an adjuvant in cancer treatment because of its capacity to prevent muscle wasting, weakness, and cachexia, it is unknown whether RE can mitigate tumor development. Two solid adenocarcinoma models (Walker-256 and Ehrlich) were used to investigate the effects of RE on tumor cell proliferation, growth, and aggressiveness parameters in tumor-bearing animals' life span.

Methods: Walker-256 tumor-bearing rats and Ehrlich tumor-bearing mice were subjected to RE, which consisted of climbing a ladder apparatus with loads tied to their tails.
