Acute Post-Activation Potentiation Effects in NCAA Division II Female Athletes

Area of Science:

• Sports Science
• Exercise Physiology
• Biomechanics

Background:

• Post-activation potentiation (PAP) is a well-documented phenomenon enhancing muscle power output following resistance exercise.
• Research on PAP predominantly focuses on male athletes, with limited data on female athletes' responses.
• Understanding PAP in female athletes is crucial for optimizing training and performance.

Purpose of the Study:

• To investigate the acute post-activation potentiation (PAP) response to back squats on static squat jump (SSJ) performance in NCAA Division II female athletes.
• To determine if PAP effects differ across various female athletic teams (basketball, softball, volleyball).

Main Methods:

• Twenty-nine female athletes from basketball, softball, and volleyball participated.
• Athletes performed SSJ tests before and after a back squat protocol at 90% of their one-repetition maximum (1RM).
• Peak power was calculated using the Sayers equation after a 5-minute rest period.

Main Results:

• A significant interaction effect was observed between time and athletic team (p=0.022).
• Post-hoc analysis revealed a significant decrease in power for the volleyball team (p=0.008).
• No significant main effect for time was found for the group overall, indicating no consistent PAP response.

Conclusions:

• The PAP response in female athletes appears highly individualized, not a uniform effect across all athletes or teams.
• Strength and conditioning coaches should consider individual strength levels and rest period duration when implementing PAP protocols for female athletes.
• Personalized training strategies are recommended to optimize PAP benefits in female athletic populations.
