The Acute Effects of Strength-Based Post-Activation Performance Enhancement on Multiple Neuromuscular Performance Variables in Male Basketball

Abstract

Purpose: The purpose of this study was to investigate the acute effects of the Heavy-Load Activation (HLA) protocol on neuromuscular performance variables, including explosive power, acceleration, and change of direction (COD) ability in male basketball players.

Method: 20 male basketball players aged 18–25 years with at least 5 years of basketball experience participated in the study. Participants were evaluated before (pre-test) and after (post-test) the HLA protocol using the Standing Long Jump (SLJ), 10 m Sprint, and 505 Agility tests. The HLA protocol consisted of 3–5 repetitions of squat exercises performed at 80–85% of each athlete’s 1 RM. Post-test measurements were conducted 6 minutes after the protocol. Data normality was assessed using the Shapiro–Wilk test, and pre- and post-test comparisons were conducted using the Paired Samples t-test or Wilcoxon Signed-Rank Test, as appropriate.

Results: Significant improvements were observed in all performance variables following the HLA protocol (p < 0.05). SLJ performance increased by 0.71% (Cohen's dz = 0.70), 10 m Sprint time decreased by 0.58% (Cohen's dz = 0.56), and 505 Agility test time decreased by 0.49% (Cohen's dz = 0.57).

Conclusion: The findings suggest that the HLA protocol may contribute to short-term improvements in explosive power, acceleration, and COD performance. HLA-based activation strategies may be considered as a practical approach for performance preparation in sports requiring rapid force production and directional changes.

Kuvvet Temelli Aktivasyon Sonrası Performans Gelişiminin Erkek Basketbolcularda Çoklu Nöromüsküler Performans Üzerindeki Akut Etkisi

Abstract

Amaç: Bu çalışmada, ağır yük aktivasyon (Heavy-Load Activation; HLA) protokolünün erkek basketbolcularda patlayıcı güç, hızlanma ve yön değiştirme (Change of Direction; COD) performansları üzerindeki kısa süreli etkilerinin incelenmesi amaçlanmıştır.

Yöntem: Araştırmaya 18–25 yaş aralığında, en az 5 yıl basketbol deneyimine sahip 20 erkek sporcu dahil edilmiştir. Katılımcılar HLA protokolü öncesinde (ön test) ve sonrasında (son test) Standing Long Jump (SLJ), 10 m Sprint ve 505 Agility testleri ile değerlendirilmiştir. HLA protokolü, sporcuların 1 RM değerlerinin %80–85’i ile uygulanan 3–5 tekrar squat egzersizlerinden oluşturulmuş ve son test ölçümleri uygulamadan 6 dakika sonra gerçekleştirilmiştir. Verilerin normal dağılımı Shapiro–Wilk testi kullanılarak değerlendirilmiş ve ön test–son test karşılaştırmaları, uygunluğuna göre Paired Samples t-testi veya Wilcoxon İşaretli Sıralar Testi kullanılarak gerçekleştirilmiştir.

Bulgular: HLA protokolü sonrasında tüm performans değişkenlerinde istatistiksel olarak anlamlı gelişmeler belirlenmiştir (p < 0,05). SLJ performansında %0,71 artış (Cohen's dz = 0,70), 10 m Sprint süresinde %0,58 azalma (Cohen's dz = 0,56) ve 505 Agility test süresinde %0,49 azalma (Cohen's dz = 0,57) görülmüştür.

Sonuç: Sonuç olarak, HLA protokolünün erkek basketbolcularda patlayıcı güç, hızlanma ve yön değiştirme performansında kısa süreli iyileşmelere katkı sağlayabileceğini göstermektedir. HLA temelli aktivasyon stratejilerinin, hızlı kuvvet üretimi ve yön değiştirme becerisi gerektiren spor dallarında performans hazırlığı kapsamında değerlendirilebilecek pratik bir yaklaşım olduğu düşünülmektedir.
