Brief Summary

The latest randomized controlled trials and systematic reviews of resistance training performed by older adults reported that the systematic use of exercise in machines improves muscle strength and power, functional abilities, body mass and body balance. However, the effect of resistance training with elastic tubes exercises have not been studied in all the variables described above. The objective of this study is to analyze the effects of elastic tubes exercises on muscle mass, muscle strength, functional performance and postural control in elderly untrained.

Conditions

Aging; Older Adults

Keywords

Aging; Resistance training; Muscle strength; Functional performance; Postural balance

Outcome Measures

Primary Outcomes (3)

• Change in Body Mass

  To assess muscle mass, a Dual-energy X-ray Absortiometry (DXA) (GE Electric Company®, Lunar Prodigy) will be used.

  Change from baseline in body mass at 16 weeks.

• Change in Muscle Strength

  Lower limb muscle strength will be assessed with an isokinetic dynamometer (Biodex System®, model III) and upper limb muscle strength with an isometric dynamometer (Jamar®, Hand Dynamometer).

  Change from baseline in muscle strength at 16 weeks.

• Change in Postural Balance

  The postural balance will be assessed with a three-dimensional (3D) motion analysis system and force plates.

  Change from baseline in postural balance at 16 weeks.

Secondary Outcomes (1)

• Change in Functional performance

  Before and after 16 weeks of resistance training

Study Arms (2)

Machine resistance training (MRT)

ACTIVE COMPARATOR

The machine resistance training will consist of four exercises for lower limbs and four exercises for upper limbs which will be alternately performed with a one-minute interval between them during familiarization and training periods. Lower limb exercises will consist of: hip extension and abduction, and knee flexion and extension. Upper limb exercises will consist of: bench press, rowing, triceps and high pulley exercise.

Other: Machines exercises

Elastic resistance training (ERT)

EXPERIMENTAL

The elastic resistance training will consist of four exercises for lower limbs and four exercises for upper limbs which will be alternately performed with a one-minute interval between them during familiarization and training periods. Lower limb exercises will consist of: hip extension and abduction, and knee flexion and extension. Upper limb exercises will consist of: bench press, rowing, triceps and high pulley exercise.

Other: Elastic exercises
