Strength Improvements of Different 10-Week Multicomponent Exercise Programs in Elderly Women

Area of Science:

• Gerontology
• Exercise Physiology
• Sports Science

Background:

• Aging is associated with sarcopenia and decreased physical function.
• Targeted strength training is crucial for maintaining health in older adults.
• Different training modalities may yield varying physiological adaptations.

Purpose of the Study:

• To compare the effects of different physical conditioning programs on elderly women.
• To assess the impact of 10 weeks of training and 4 weeks of detraining.
• To evaluate changes in physical conditioning, body composition, and hematology.

Main Methods:

• 48 elderly women were randomized into four groups: physical conditioning (PCG), PCG with hypertrophy focus (PCGH), PCG with aquatic focus (PCGP), and a control group (CG).
• Training interventions lasted 10 weeks, followed by 4 weeks of detraining.
• Assessments included strength tests (Abalakov, Countermovement Jump, chair-stand), body composition, and hematological markers.

Main Results:

• The PCGH group showed significant increases in Abalakov test performance.
• Countermovement Jump showed significant differences between the control group and other training groups.
• PCG and PCGH groups demonstrated significant improvements in the chair-stand test.
• Training interventions suggested positive changes in HDL, LDL, glucose, and glycated hemoglobin levels.

Conclusions:

• A physical conditioning program incorporating an extra hypertrophy-focused session yielded superior strength gains in elderly women.
• Specific training protocols can effectively enhance muscular strength and physical function in older adults.
• Further research is warranted to explore the long-term effects and optimal training strategies for this demographic.
