Current Other Outcome Measures ^ICMJE (submitted: October 12, 2012)	Change in muscle volume [ Time Frame: Baseline, 12weeks, 6 months ] [ Designated as safety issue: No ] Change in maximal strength (one repetition maximum) [ Time Frame: Baseline, 4weeks, 8weeks, 12weeks, 6 months ] [ Designated as safety issue: No ] Strength is measured as the maximum weight on the training equipment that can be lifted only one time (= one repetition maximum).

Descriptive Information
Brief Title ^ICMJE	The Effects of Low- and High-intensity Resistance Exercise on Force-velocity Characteristics in Older Adults
Official Title ^ICMJE	Not Provided
Brief Summary	The purpose of this study is to compare the impact of high- and low-intensity resistance exercise on force-velocity characteristics, muscle mass and inflammatory processes in older adults. As all training protocols are designed to end with maximal effort, effects are expected to be similar between groups.
