Primary Outcome Measures

Name	Time	Method
It is expected a difference on strength gain (torque) between the different eight-weeks strength training protocols, even though matched for equivalent volume and intensity.<br>Muscle torque will be evaluated by an isokinetic dynamometer Cybex 6000.<br>Increse in muscle torque after eigth weeks of strength training will be assessed by Cybex dynamometer.<br>A difference of at least 30% of torque gain in the pre and post training among different groups will be considered. (ANOVA - time x group);Isometric group had the largest increase on isometric torque (30.2%) after eight weeks of strength training compared to isotonic and isokinetic group

Secondary Outcome Measures

Name	Time	Method
It is expected a difference on muscle mass gain between the different eight-weeks training protocols , although matched for equivalent volume and intensity.<br>Muscle mass will be evaluated by DEXA and functional performance by the triple hop distance test.<br>Muscle mass will be evaluated by the percentage gain in muscle lean mass of the trained leg.;Isometric (3.1%) and isotonic training (3.9%) significantly increased muscle mass after eight weeks of strength training.<br>;It is expected a difference on functional performance gain between the different eight-weeks training protocols , although matched for equivalent volume and intensity.<br>Functional performance will be evaluated by the triple hop distance test.<br>Functional performance will be assessed by the percentage gain of the triple hop distance in centimeters .;The isokinetic trainig led to a significant improvement of performance in the triple hop distance (4.8%) after eigth weeks of strength training.
