The Effects of Different Intensity Training on Strength and Mobility of Elderly

The Effects of High-, Moderate-, and Low-intensity Training on Muscle Strength and Functional Mobility of Older Adults: A Randomized Controlled Trial

In this study, investigators tried to find a useful and safe way of training for the elderly population which can help this population to improve their fitness factors as fast as possible. investigators have tried to see if different intensity training has different effects on muscle strength and functional mobility of elderly women in different time points (4, 8, and 12 weeks). Investigators hypothesized that Higher intensity would be more effective to improve muscle strength and functional mobility at different time points. The participants were trained twice per week and each session contain 4 exercises ( leg press, leg extension, leg curl, and seated calf raises) and the data have been collected at the pre-test and 4th, 8th, and 12th weeks of intervention.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 65 years and older (Older Adult)
• Accepts Healthy Volunteers: Yes
• Genders Eligible for Study: Female

Description

Inclusion Criteria:

• Aged 65 years old and above.
• Orientation to place, time, and person, able to follow the simple instructions, and perform the exercises.
• Without any health problems that would interfere with their safety or ability to complete high and low-intensity training such as the occurrence of myocardial infarction in the past six months, recent heart attack, uncontrolled hypertension (Blood Pressure >166/96 mm Hg), a broken leg in the past six months, diagnosed osteoporosis, and diagnosed stage three and four of heart failure.

Exclusion Criteria:

• Participation in regular balance or lower body resistance training during the past three months (at least twice per week).
• The health issues that might confound the study results, including lower-body neuropathy, stroke within the past year, Parkinson's disease, diagnosed vestibular disorders, severe vision (self-rated vision as poor or very poor even when wearing glasses or contact lenses), and lower-extremity joint replacements.
• Taking the regular medication's impairing balance ability (Antidepressants, Neuroleptics or Benzodiazepines) or muscle strength (Corticosteroids).
• Elderly with dementia

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: High Intensity Training (HIT); They have trained at 80-90% of 1RM for 12 weeks, twice per week	Other: Training; Resistance training (4 different exercises, leg press, leg extension, leg curl, and seated calf raises)
Experimental: Moderate Intensity Training; They have trained at 65-75% of 1RM for 12 weeks, twice per week	Other: Training; Resistance training (4 different exercises, leg press, leg extension, leg curl, and seated calf raises)
Experimental: Low Intensity Training; They have trained at 50-60% of 1RM for 12 weeks, twice per week	Other: Training; Resistance training (4 different exercises, leg press, leg extension, leg curl, and seated calf raises)
No Intervention: Control Group; This groups subjects did not participate in any training

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from Baseline in the Mean of 5 Time Sit to Stand Test at 4, 8, and 12 weeks	The timed that subject complete 5 times sit to stand recorded in second using a stop watch. The lower score is better	Baseline, 4th weeks, 8th weeks, 12th weeks
Change from Baseline in the Mean of the Timed Up and Go Test at 4, 8, and 12 weeks	The timed that subject complete the test recorded in second using a stop watch. The lower score is better	Baseline, 4th weeks, 8th weeks, 12th weeks
Change from Baseline in the Mean of the 6 Minutes Walking Test at 4, 8, and 12 weeks	The distance that subject walk in six minutes measured in centimetre. The higher score is better	Baseline, 4th weeks, 8th weeks, 12th weeks
