Brief Summary

The purpose of this study is to compare the effects of three different recovery strategies-sports massage (SM), static stretching (SS), and passive rest (PR)-on physiological and neuromuscular recovery in adolescent male judokas. Additionally, the study investigates the role of diurnal variation (morning vs. evening sessions) on recovery performance. Thirteen competitive adolescent judokas participated in a randomized crossover design. Recovery was assessed using physiological markers such as heart rate (HR) and blood lactate (La-) levels, as well as neuromuscular performance through countermovement jump (CMJ) and medicine ball throw tests. The findings aim to identify the most effective recovery modality for young athletes to optimize performance and prevent overtraining during intensive training or competition schedules.

Conditions

Judo; Athletic Performance; Muscle Fatigue; Adolescent; Recovery of Function (G11.427.698.620)

Keywords

judo; recovery; massage; stretching; circadian rhythm; adolescent athletes; blood lactate; countermovement jump

Outcome Measures

Primary Outcomes (1)

• blood lactate concentration

  Lactate levels were measured to assess the physiological recovery of the participants after judo-specific tasks.

  Measured at 4 time points: Baseline (before exercise), immediately after exercise, 5 minutes after recovery protocol, and 10 minutes after recovery protocol.

Secondary Outcomes (3)

• Countermovement jump height

  Baselibe (pre-post) and after 10-minute recovery period

• Handgrip strength

  Baseline (pre-test) and after the 10-minute recovery period

• Borg Rating of Perceived Exertion

  Immediately after the judo match

Study Arms (3)

Sport Massage (SM)

EXPERIMENTAL

Participants received a 10- minute sports massage focusing on the lower and upper body muscles

Other: Sports Massage

Static Stretching (SS)

EXPERIMENTAL

Participants performed 10 minutes of static stretching exercises targeting major muscle groups.

Other: Static Stretching

Passive Rest (PR)

EXPERIMENTAL

Participants rested quietly in a seated position for 10 minutes

Other: Passive Rest

Interventions

Sports Massage OTHER

A 10-minute sports massage protocol was applied to the major muscle groups of the lower and upper body, specifically those involved in judo movements, to facilitate recovery.

Also known as: SM

Sport Massage (SM)

Static Stretching OTHER

A 10-minute static stretching session involving major muscle groups. Each stretch was held for a duration consistent with clinical standards to the point of mild discomfort

Also known as: SS

Static Stretching (SS)

Passive Rest OTHER

Participants rested quietly in a seated position for 10 minutes in a neutral environment, with no physical activity or external stimulation.

Also known as: PS

Passive Rest (PR)
