Brief Summary

This randomized, parallel-group clinical trial evaluates a 12-week adapted CrossFit program versus usual activity in community-dwelling older adults. The primary endpoint is change in Timed Up and Go (TUG) from baseline to 12 weeks. Secondary outcomes include Functional Reach (FRT), Romberg (eyes closed), gait velocity, stride length, and lower-limb power tests (Chair-Stand, Stair Ascent, Stair Descent; time and W/kg). Sixty participants were randomized (1:1). Analyses used repeated-measures ANOVA with Bonferroni adjustments and Cohen's d effect sizes.

Outcome Measures

Primary Outcomes (1)

• Timed Up and Go (TUG), seconds

  Change in functional mobility. Shorter time indicates better performance and reduced risk of falls.

  Baseline and Week 12

Secondary Outcomes (8)

• Functional Reach Test (FRT)

  Baseline and 12 weeks

• Chair-Stand Test (CST)

  Baseline and 12 weeks

• Fear of Falling (Falls Efficacy Scale-International, FES-I)

  Baseline and week 12

• Sleep Quality (Pittsburgh Sleep Quality Index, PSQI)

  Baseline and week 12

• Anxiety and Depression (Hospital Anxiety and Depression Scale, HADS)

  Baseline and week 12

Study Arms (2)

Adapted CrossFit Program

EXPERIMENTAL

Supervised, scaled functional multi-joint training tailored to older adults, combining strength and metabolic conditioning with progressive overload over 12 weeks.

Behavioral: Adapted CrossFit Program (12 weeks)

Usual Activity (Control)

NO INTERVENTION

Participants maintain habitual daily activities with no structured training.

Interventions

Adapted CrossFit Program (12 weeks) BEHAVIORAL

Supervised sessions focused on functional, multi-joint movements adapted for older adults; emphasis on safety and progressive overload.

Adapted CrossFit Program

Eligibility Criteria

• Age: 65 Years - 80 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Older Adult (65+)

You may qualify if:

• Community-dwelling older adults able to walk independently without assistance.
• Cognitive function preserved, defined as a score of 26 points or higher on the Mini-Mental State Examination.
• Absence of severe health conditions that would interfere with participation in exercise training.

You may not qualify if:

• Presence of active neuromuscular or musculoskeletal disorders that prevent safe exercise participation.
• Severe cardiovascular, pulmonary, or metabolic disease that contraindicates moderate-intensity exercise.
• Any other medical or psychological condition that, in the opinion of the investigators, would make participation unsafe or unreliable.
