About this study

Official title: Effects of Caffeine, Rhodiola Rosea, and Combined Supplementation on Cowboy-Dance-Specific Explosive Power, Movement Stability, and Muscular Endurance in Male Collegiate Dancesport Athletes

This study evaluates the effects of caffeine, Rhodiola rosea, and their combined supplementation on dancesport-specific performance in male collegiate dancesport athletes. Forty-eight healthy male athletes aged 18 to 23 years will be randomly assigned to one of four groups: placebo control, caffeine, Rhodiola rosea, or combined Rhodiola rosea plus caffeine. All participants will complete the same four-week standardized cowboy-dance-specific training program. The caffeine group will receive caffeine at 3 mg·kg-¹ before testing, the Rhodiola rosea group will receive Rhodiola rosea at 2.4 g·day-¹ for four weeks, and the combined group will receive both supplementation strategies.

The main purpose of this study is to determine whether these supplementation strategies improve cowboy-dance-specific explosive power, movement stability, repeated kicking performance, agility, muscular endurance, and perceived exertion. Main outcomes include the 180-degree kick straight angle, kick recoil angle, trunk anterior-posterior sway amplitude, and 30-second cowboy-kick success rate. Secondary outcomes include qualified kick count, balance, core stability, functional strength, rhythm accuracy, agility tests, hexagon jump performance, and session-RPE.

Read the detailed description

This randomized, double-blind, placebo-controlled, parallel-group study is designed to examine the effects of caffeine, Rhodiola rosea, and combined supplementation on cowboy-dance-specific performance in male collegiate dancesport athletes. The study uses a four-arm design with 48 participants randomly assigned equally to placebo control, caffeine, Rhodiola rosea, or combined Rhodiola rosea plus caffeine groups.

All participants will complete a standardized four-week cowboy-dance-specific training program. The training program focuses on dance-specific rhythm, repeated kicking, kick recoil control, trunk stability, lower-limb explosive actions, functional strength, agility, and repeated movement quality. The control group will receive placebo capsules. The caffeine group will receive caffeine at 3 mg·kg-¹ before testing. The Rhodiola rosea group will receive Rhodiola rosea at 2.4 g·day-¹ for four weeks. The combined supplementation group will receive Rhodiola rosea for four weeks and caffeine before testing.

Performance will be assessed at baseline and immediately after the four-week intervention. Primary outcomes include the 180-degree kick straight angle, kick recoil angle, trunk anterior-posterior sway amplitude, and 30-second cowboy-kick success rate. Secondary outcomes include 30-second qualified kick count, Y-Balance Test composite score, bird-dog core stability hold time, lunge squat and step-up qualified repetitions, 45-second high-knee rhythm accuracy, 505 change-of-direction time, Illinois agility run time, hexagon jump time, and session-RPE.

This study aims to clarify whether caffeine mainly supports rapid movement initiation and agility, whether Rhodiola rosea mainly supports movement stability and perceived load regulation, and whether combined supplementation provides broader benefits for cowboy-dance-specific movement quality.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 180-degree kick straight angle

    Maximum knee extension angle during the standardized cowboy-dance kick task. Higher values indicate better kick extension quality.

    Measured: Baseline and immediately after 4-week intervention

  2. Kick recoil angle

    Maximum recoil angle of the kicking leg after the kick, reflecting braking control and preparation for the next beat. Higher values indicate better recovery control.

    Measured: Baseline and immediately after 4-week intervention

  3. Trunk anterior-posterior sway amplitude

    Anterior-posterior trunk sway amplitude during continuous cowboy-dance kicking. Lower values indicate better trunk stability.

    Measured: Baseline and immediately after 4-week intervention

  4. 30-second cowboy-kick success rate

    Percentage of qualified kicks completed during a 30-second cowboy-dance kicking task consisting of 32 kicks.

    Measured: Baseline and immediately after 4-week intervention

Secondary outcomes (10)
  1. 30-second cowboy-kick qualified count

    Number of qualified kicks completed during the 30-second cowboy-dance kicking task.

    Measured: Baseline and immediately after 4-week intervention

  2. Y-Balance Test composite score

    Composite dynamic balance score derived from the Y-Balance Test.

    Measured: Baseline and immediately after 4-week intervention

  3. Bird-dog core stability hold time

    Effective hold time during the standardized bird-dog core stability task.

    Measured: Baseline and immediately after 4-week intervention

  4. Lunge squat total qualified repetitions

    Total number of qualified repetitions completed across four sets of lunge squat exercise.

    Measured: Baseline and immediately after 4-week intervention

  5. Step-up total qualified repetitions

    Total number of qualified repetitions completed across four sets of step-up exercise.

  6. 45-second high-knee rhythm accuracy

    Percentage of rhythm-accurate movements during the 45-second high-knee task.

    Measured: Baseline and immediately after 4-week intervention

  7. 505 change-of-direction best time

    Best completion time in the 505 change-of-direction test. Lower time indicates better agility.

    Measured: Baseline and immediately after 4-week intervention

  8. Illinois agility run best time

    Best completion time in the Illinois agility run. Lower time indicates better agility.

    Measured: Baseline and immediately after 4-week intervention

  9. Hexagon jump best time

    Best completion time in the hexagon jump test. Lower time indicates better multidirectional jumping ability.

    Measured: Baseline and immediately after 4-week intervention
