Conditions
Interventions
Behavioral : Participants in both the eccentric resistance training group (ECC) and the concentric resistance training group (CON) perform supervised trunk extensor exercise on an isokinetic dynamomet
participants are instructed to resist this movement maximally throughout the range. In the CON group, the dynamometer is set to a concentric mode so that the trunk extensors contract while shortening
