Study aim
-
Determining the effect of 8 weeks of aerobic and resistance training on serum levels of N-terminal peptide type 3 (P3NP), agrin C fragment (CAF), creatinine to cystatin C ratio, some functional indices (upper and lower body strength, aerobic endurance, balance), some body composition indices (weight, body mass index, fat mass and muscle mass) in elderly women
-
Design
-
A quasi-experimental design with a control group, with factorial groups, single-blind, randomized on 36 elderly people, Randomi allocation software will be used for randomization.
-
Settings and conduct
-
It will be conducted in the field of exercise physiology in the city of Tabriz, and the participants will be unaware of how the other groups performed.
-
Participants/Inclusion and exclusion criteria
-
1. No medication
2. No specific skeletal disease
3. No underlying disease
4. Ability to perform sports
5. Women aged 65 to 75
6. No metabolic disease (diabetes, blood pressure, high cholesterol, etc.)
7. Possibility of sarcopenia (decreased muscle function)
8. No risk factors (chest pain, heart attack in first-degree relatives, limping when walking, etc.)
-
Intervention groups
-
The aerobic exercise group will perform simple aerobic activities, walking, jogging and slow running continuously and in the form of 8.
The resistance group exercises include movements that involve the main muscle groups. Initially, movements will be performed for 10 to 15 repetitions then will increase to 8 to 12 repetitions. The intensity of the movements will also range from 40 to 50% of 1RM to 60 to 80% of 1RM.
The control group will follow the normal course of daily activities.
-
Main outcome variables
-
Preventing sarcopenia and dynapenia in the elderly, which ultimately improves life in the elderly and reduces the burden of additional costs and independence of the elderly.
