About this study
Official title: Strength Training and Modified CrossFit in Older Adults: a Comparative Perspective
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.
Read the detailed description
Participants were screened and randomized (1:1) to an adapted CrossFit program (12 weeks) or to maintain usual activities (no structured training). Baseline characterization included demographics, anthropometrics, Mini-Mental State Examination (MMSE ≥ 26), physical activity level, and handgrip strength. Balance outcomes: Romberg (s, eyes closed), gait velocity (m/s), stride length (cm), TUG (s), and FRT (cm). Lower-limb power: Chair-Stand (s; W/kg), Stair Ascent/Descent (s; W/kg). Statistical analysis: normality (Shapiro-Wilk), homogeneity (Levene), repeated-measures ANOVA with Bonferroni post-hoc, and Cohen's d effect sizes. A priori sample size (G*Power 3.1): effect size 0.25, α = 0.05, power 0.80 → target n = 60 to account for attrition.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Adapted CrossFit Program (12 weeks)Behavioural
Supervised sessions focused on functional, multi-joint movements adapted for older adults; emphasis on safety and progressive overload.
| Study group | Role | What they receive |
|---|---|---|
| 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. Receives: Behavioral: Adapted CrossFit Program (12 weeks) |
| Usual Activity (Control) | No intervention | Participants maintain habitual daily activities with no structured training. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Timed Up and Go (TUG), seconds
Change in functional mobility. Shorter time indicates better performance and reduced risk of falls.
Measured: Baseline and Week 12
Secondary outcomes (8)
Functional Reach Test (FRT)
Change in dynamic balance assessed by the distance a participant can reach forward without losing stability. Greater distance indicates better balance.
Measured: Baseline and 12 weeks
Chair-Stand Test (CST)
Sit-to-stand repetitions (5 times). Lower time and higher relative power indicate better lower-limb strength and functional capacity.
Measured: Baseline and 12 weeks
Fear of Falling (Falls Efficacy Scale-International, FES-I)
Self-reported concern about falling during daily activities. Higher scores indicate greater fear of falling.
Measured: Baseline and week 12
Sleep Quality (Pittsburgh Sleep Quality Index, PSQI)
Subjective sleep quality over the previous month. Higher scores indicate poorer sleep quality.
Measured: Baseline and week 12
Anxiety and Depression (Hospital Anxiety and Depression Scale, HADS)
Symptoms of anxiety and depression measured with HADS. Higher subscale scores indicate greater severity.
Measured: Baseline and week 12
Gait Velocity, meters per second
Walking speed measured over a standardized distance. Higher speed indicates better mobility.
Measured: Baseline and week 12
Stride Length, centimeters
Average step length during gait assessment. Longer stride indicates better gait performance.
Measured: Baseline and week 12
Kinesiophobia (Tampa Scale of Kinesiophobia, TSK)
Fear of movement measured with the Tampa Scale. Higher scores indicate greater kinesiophobia.
Measured: Baseline and week 12

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Timed Up and Go (TUG), seconds (time frame: Baseline and Week 12). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Sep 2025.
