Abstract

Penggunaan media kolam air dalam beberapa tahun terakhir semakin populer dikalangan pelatih. Salah metode yang digunakan yaitu penggunaan metode latihan aquatic plyometric. Latihan plyometric tradisonal sering kali membuat atlet cedera. Tujuan penelitian ini untuk mengetahui dampak penggunaan latihan aquatic plyometric dalam meningkatkan performa dan mencegah cedera. Metode yang digunakan dalam penelitian ini menggunakan pendekatan tinjauan pustaka, dengan mengumpulkan artikel dari database ilmiah seperti Scopus, PubMed, dan Google Scholar, menggunakan kata kunci seperti “Aquatic plyometric, “performa”, dan “cedera otot”. Dalam dua bahasa, dengan rentang tahun publikasi 2016–2024. Penelusuran dibantu oleh aplikasi Publish or Perish. Pemilihan artikel mengikuti tahapan PRISMA: (1) mendefinisikan topik dan kriteria, (2) menentukan sumber informasi, (3) memilih literatur relevan, (4) mengumpulkan artikel, dan (5) menganalisis artikel. Hasil dari penelitian ini sebanyak 324 diidentifikasi, dimana 9 memenuhi syarat dan kriteria kelayakan sepenuhnya ditinjau. Hasil penelitian menunjukan bahwa latihan aquatick plyometric dapat menjadi alternatif yang efektif dalam meningkatkan performa atlet dengan risiko cedera yang lebih rendah dibandingkan dengan latihan plyometric di darat. Meskipun demikian, latihan di darat masih lebih unggul dalam meningkatkan beberapa aspek kinerja fisik tertentu, seperti lompatan reaktif. Penelitian ini menyarankan bahwa ketinggian air dan variasi latihan aquatic plyometric memiliki pengaruh yang signifikan dalam meningkatkan performa atlet. Ketinggian air yang berbeda dapat memengaruhi tingkat resistensi dan daya apung, yang pada akhirnya berdampak pada efektivitas latihan dalam mengembangkan kekuatan eksplosif, kecepatan, dan daya tahan otot. Selain itu, variasi dalam latihan aquatic plyometric, seperti penggunaan beban tambahan atau modifikasi gerakan, dapat memberikan stimulus yang lebih optimal bagi adaptasi fisik atlet.

Abstract

Background Sodium bicarbonate (NaHCO₃) has gained substantial attention as an ergogenic aid due to its buffering capacity, which helps mitigate exercise-induced metabolic acidosis. Its use has been widely explored in high-intensity sports where the accumulation of hydrogen ions contributes to early muscle fatigue and decreased performance. Objectives This systematic review aims to synthesize current empirical evidence regarding the effectiveness of sodium bicarbonate supplementation in enhancing endurance-related performance outcomes, with a particular focus on its role in delaying muscle fatigue during exercise. Methods A Systematic Literature Review (SLR) was conducted following the PRISMA guidelines. Article identification and selection employed the PICO framework. Relevant studies were retrieved from Scopus, ScienceDirect, Web of Science, and PubMed using the keywords “sodium bicarbonate,” “endurance,” “performance,” and “muscle fatigue.” Nine peer-reviewed studies met the inclusion criteria and were analyzed descriptively to evaluate the effects of sodium bicarbonate on athletic performance. Results The findings indicate that sodium bicarbonate supplementation can enhance performance, particularly in high-intensity and short-to-medium-duration activities. However, its effectiveness is highly context-dependent and influenced by exercise modality, duration and intensity, athlete training status, and supplementation protocol—including dosage, timing, and individual physiological tolerance. Several studies employed relatively small and homogeneous samples, limiting the generalizability of the results. Conclusion Sodium bicarbonate shows consistent potential as an ergogenic supplement for improving endurance-related performance by attenuating metabolic fatigue. Nonetheless, its benefits are not uniform across all athletes or sport types. Optimal outcomes appear to require individualized dosing strategies and sport-specific application. This review provides an updated synthesis of evidence on sodium bicarbonate supplementation and highlights critical variables that moderate its effectiveness. The study underscores the need for individualized supplementation protocols and encourages future research employing larger, more diverse athlete populations and standardized ergogenic assessment methods.

Abstract

Purpose: This study was motivated by the importance of the role of psychological aspects, especially mental toughness, in supporting athletes' abilities when facing anxiety in a match. Materials and Methods: This study used a meta-analysis method. The search used the Publish and Publish application, with Google Scholar as the database. Literature searches from various sources used the keywords: "Mental Toughness", "Athlete Anxiety", "Competitive Anxiety", "Performance Anxiety", and "Sports Psychology". Five hundred eighteen articles were obtained, which were then filtered based on inclusion and exclusion criteria, and 23 articles were analyzed. Result: The results of the analysis show a negative relationship in the moderate category between mental toughness and competitive anxiety, with rRE = -0.320 (z = -3.030; p < 0.002; 95% CI: -0.113 to -0.528). Egger's test showed no publication bias (p = 0.748 > 0.05). Conclusion: These findings suggest that increased mental toughness is negatively associated with athletes' levels of competitive anxiety. In other words, the higher an athlete's level of mental toughness, the lower their anåxiety levels during competition. This research suggests that coaches and sports psychologists are crucial to integrating psychological practices, such as goal setting, positive self-talk, and imagery, into athletes' training programs. This approach can help improve mental toughness and reduce athletes' anxiety during competition.
