Design outcomes

Primary

MeasureTime frame
Perceived recovery: It is determined using perceived recovery status scale. Participants select an integer between 0 and 10 from a segmented version of the scale that most accurately reflects their perceived level of recovery. This 11-point scale ranges from 0, indicating “not recovered at all”, to 10, indicating “fully recovered”. Timepoint: Before the intervention, immediately after the intervention, and 24 hours after the intervention. Method of measurement: Perceived recovery status scale (PRSS): Participants select an integer between 0 and 10 from a segmented version of the scale that most accurately reflects their perceived level of recovery. This 11-point scale ranges from 0, indicating “not recovered at all”, to 10, indicating “fully recovered”.

Secondary

MeasureTime frame
Muscular Power: Muscular power is defined as the amount of work performed by a muscle per unit of time and is related to both the magnitude of force and the speed of movement; in other words, power represents the rate at which work is performed. In the present study, this concept refers to upper limb muscular power, which is assessed using the Seated Medicine Ball Chest Pass Test. Timepoint: Before the intervention, immediately after the intervention, and 24 hours after the intervention. Method of measurement: The participant sits on the floor with the head, shoulders, back, and hips fully in contact with the wall, and the legs extended straight forward. The participant holds a 2-kg medicine ball with both hands at chest level. A measuring tape is placed on the floor with one end fixed to the wall. Without allowing the head, shoulders, back, or hips to lose contact with the wall, the participant throws the ball forward horizontally with maximal effort to achieve the greatest possible distance. Before each throw, the ball is dusted with magnesium carbonate (gym chalk) so that it leaves a clear mark on the floor at the point of first contact, facilitating distance measurement. The participant performs three maximal-effort throws, with a one-minute rest interval between attempts. The distance from the wall to the first point where the ball contacts the floor is recorded as the throw distance. The greatest distance achieved among the three trials is normalized to the participant’s height and recorded as the test result. A throw is considered invalid and must be repeated if: 1. The throw is not performed horizontally from the chest (the angle is visually monitored by the researcher), 2. The participant lifts the feet off the floor, or 3. The head, back, or hips lose contact with the wall.;Upper limb functional balance: Upper Limb Functional Balance refers to the body’s ability to maintain stability and control upper limb movements in various dynamic positions, allowing t
