Efficacy Testing of Les Mills Pilates

May 9, 2024 updated by: Gillian Hatfield, University of the Fraser Valley
Objectives: Determine the effect of an 8-week intervention of the new group fitness program Les Mills Pilates on balance, core stability, abdominal, back, and hip muscle endurance, flexibility, and mood. Research questions: Does doing Les Mills Pilates twice per week for 8 weeks result in: 1) increased balance, 2) increased core stability, 3) increased abdominal, back, and hip muscle endurance, 4) increased flexibility, and 5) improved mood? Intended outcomes: this study will determine the efficacy of a new group fitness program developed by Les Mills International. Results will be used to help refine the program, as well as in marketing of the program.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Core endurance (time to failure in seconds)
Time Frame: 8 weeks
Endurance of the core muscles- abdominals, back extensors, hip extensors, quadriceps- time to hold a plank (abdominals), biering-sorenson test (back extensors), unilateral hip bridge (hip extensors), wall sit (quadriceps) will be recorded. Participants will hold each position until failure. Higher times to reach failure indicate more endurance (better value).
8 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Balance (single leg reach distance in cm)
Time Frame: 8 weeks
Y-balance test- distance in cm. Higher distances are better outcomes.
8 weeks
Core stability: Sahrmann trunk stability test
Time Frame: 8 weeks
Sahrmann trunk stability test- maximum level participants can perform with neutral lumbar spine. Level 1 (minimum value) to Level 5 (maximum value). Higher scores are better outcome.
8 weeks
Flexibility in cm
Time Frame: 8 weeks
Forward reach test. Participants sit with legs extended and reach forward as far as they can. Reach distance is measured. Higher scores are better outcome (more flexibility).
8 weeks
Mood
Time Frame: Daily for 8 weeks
Perceived motivation, stress and fatigue on 0 (minimum value) -5 (maximum value) Likert scale, where higher numbers indicate more motivation (better outcome), stress (worst outcome), or fatigue (worse outcome)
Daily for 8 weeks
