[Postural stability during static strain before and after submaximal aerobic bycycle test in athletes]

Area of Science:

• Sports Science
• Biomechanics
• Exercise Physiology

Context:

• Static balance and postural control are crucial for athletic performance.
• Fatigue is known to negatively impact motor control and stability.
• Wrestlers, as a population, undergo rigorous physical training that may influence their balance capabilities.

Purpose:

• To investigate static balance control in wrestlers compared to controls.
• To examine the effects of physical fatigue on postural regulation in wrestlers and controls.
• To assess balance in bipedal and squat stances before and after a maximal exercise test (PWC170).

Summary:

• Wrestlers demonstrated minimal differences in bipedal stance balance compared to controls pre-exercise.
• In a squat position, wrestlers exhibited significantly lower center of pressure sway velocities, correlated with their physical working capacity (PWC170).
• Post-exercise, all sway parameters increased in both groups, highlighting the role of muscular fatigue in reduced postural stability. Wrestlers showed less sway velocity increase in the squat position post-fatigue, linked to heart rate recovery rate.

Impact:

• Findings suggest that wrestlers possess enhanced static balance, particularly under strain.
• Muscular fatigue significantly degrades postural control, underscoring the importance of fatigue management in sports.
• Heart rate recovery rate may contribute to maintaining postural stability in athletes during fatigue, offering insights for training and recovery strategies.
