Abstract

In addition to good physical and psychological conditions, recovery is another important component that athletes must meet to support success in the field. This study aims to determine the effect of active and passive recovery on plyometric exercises on speed and power. The type used in this study is quasi-experimental. The sample of this research is 44 athletes from Lampung Province who will compete for Pekan Olahraga Nasional (PON) 2021 Papua. The plyometric exercises applied are plyometric exercises (multiple hops and jump variations). After doing the plyometric exercises, active and passive recovery is applied. The speed research instrument is the 30 m sprint test for power using a vertical jump. Analysis of the data used: paired test analysis and independent sample test. The results obtained are that plyometric exercises on active and passive recovery affect athletes' speed and power abilities. Although it affects performance, in the effectiveness test, the speed of active recovery is better than passive recovery. As for power, both of them do not have the level of effectiveness between passive and active recovery. The study's results are expected to be a reference to be included in the training program using the plyometric model with active and passive recovery to support the success of the Lampung Province athletes in 2021.

Abstract

This study aims to describe the transformation of mathematical communication skills in high school students through the use of problem-solving scaffolding. Transformation is interpreted as a change in the way students convey mathematical ideas and solutions through writing, visuals, and symbols. The study employed a descriptive qualitative approach, utilizing data from TPMKM, think-aloud sessions, and semi-structured interviews. The analysis was carried out based on the Polya stages and source triangulation. The results showed that students in the low category before scaffolding only met the written text (Wr1) and partial mathematical expression (Me) indicators. After scaffolding, they meet Wr1, Wr2, Wr3, Dr, and Me more completely. Meanwhile, students in the medium category initially met Wr1, part of Wr2, and part of Me. After scaffolding, they showed significant changes: they were able to meet Wr1, Wr2, Wr3, Dr, and Me in their entirety. This transformation reflects a process of assimilation, accommodation, and equilibrium, which changes the student's categories from low to medium and from medium to high.

Abstract

Background: Vaping is now a trend for a tobacco-smoking alternative. However, studies and regulations regarding the side effects of vaping are limited. Recently, vaping-associated spontaneous pneumothorax cases were reported. Pneumothorax, when air accumulates in the pleural cavity, could progress to an emergency case. It is rarely related to physical exercise.Case Presentation: We found two spontaneous pneumothorax cases in Diponegoro National Hospital that presented with chest pain and cough post-exercise in vaping adolescents. The diagnosis was established based on medical history, physical examination, and chest X-ray. Both patients were treated with water-sealed drainage (WSD) and intensive care.Conclusion: Pneumothorax is an important diagnosis to consider in vaping patients, resulting in long stay and high-cost hospitalization. Vaping-associated spontaneous pneumothorax cases in active adolescents should receive special attention for conducting electronic cigarette studies and regulations in Indonesia.

Abstract

Kegiatan senam di lingkungan perguruan tinggi menjadi sarana pengembangan minat dan kebugaran mahasiswa sekaligus bentuk kontribusi terhadap Masyarakat. Namun, dalam pelaksanaan program UKM Senam Universitas Negeri Semarang, jumlah partisipasi member cenderung menurun sehingga menimbulkan dugaan adanya masalah dalam kualitas pelayanan dan Kepuasan member. Kondisi tersebut menjadi dasar dalam penelitian ini. Penelitian ini bertujuan untuk menganalisis Tingkat kualitas pelayanan dan kepuasan member Senam pada UKM Senam Universitas Negeri Semarang tahun 2025. Metode yang di gunakan dalam penelitian ini adalah deskriptif kuantitatif dengan Teknik pengumpulan data melalui kuesioner menggunakan skala likert dengan jumlah responden sebanyak 77 member. Hasil penelitian menujukan bahwa Tingkat kualitas pelayanan dan kepuasan member memiliki kategori yang rendah. Pada hasil penelitian tingkat kualitas pelayanan terdapat hasil kategori sangat rendah dengan persentase 4%, kategori rendah 38%, kategori sedang 26%, kategori tinggi 18% dan kategori sangat tinggi 14%. Sedangkan pada hasil kepuasan member terdapat kategori sangat rendah 6%, kategori rendah 34%, kategori sedang 31%, kategori tinggi 12%, dan kategori sangat tinggi 17%. Temuan ini menunjukkan bahwa tingkat kualitas pelayanan dan kepuasan member perlu masih perlu ditingkatkan dengan cara evaluasi secara menyeluruh terhadap manajemen waktu pelaksanaan kegiatan dan kualitas program latihan, serta untuk menciptakan kualitas pelayanan member yang berkualitas dan memuaskan.

Abstract

Background: Hamstring strength imbalance between the left and right sides has been identified as a factor contributing to increased injury risk in athletes. However, few studies have evaluated not only bilateral strength differences but also the magnitude of clinically significant imbalances in various hamstring strength parameters. Objective: This study aims to analyze bilateral hamstring muscle asymmetry in terms of maximum, average, and maximum impulse strength, and to evaluate whether the distribution of high imbalances reaches clinically relevant thresholds associated with potential injury risk. Methods: This study is a cross-sectional observational study. Twenty athletes (n = 20) underwent hamstring strength measurements using the NordBord Hamstring Testing System. The parameters analyzed included maximum force, average force, and maximum impulse on the left and right sides. Normality was assessed using the Shapiro–Wilk test. Bilateral comparisons were analyzed using paired t-tests or Wilcoxon signed-rank tests, depending on data distribution, and accompanied by effect size calculations (Cohen's d). Imbalance (%) was calculated for each parameter and classified into low-, moderate-, and high-risk categories. Risk category distribution was analyzed using a binomial test with a clinical reference value of 20%. Result: There were significant bilateral differences in several hamstring strength parameters (p < 0.05) with moderate to large effect sizes. The imbalance analysis showed that the proportion of athletes with high max impulse imbalance (45%) was significantly higher than the clinical threshold (p = 0.010). Conversely, the proportion of high imbalance in maximum force and average force did not differ significantly from the clinical reference value (p > 0.05). Conclusion: Although bilateral hamstring strength differences were found, only maximum impulse imbalance showed clinically relevant significance regarding potential injury risk. These findings emphasize the importance of including impulse analysis, in addition to force, in hamstring injury risk screening using NordBord.

Abstract

Penelitian ini bertujuan untuk mengetahui tingkat kecemasan pemain sepakbola Persiwi Wonogiri U-17 dalam pertandingan resmi Piala Soeratin 2025. Penelitian menggunakan metode deskriptif kuantitatif dengan sampel 29 pemain yang dipilih melalui teknik purposive sampling berdasarkan kriteria tertentu. Instrumen yang digunakan adalah angket tertutup berbasis Competitive State Anxiety Inventory–2R (CSAI-2R) yang telah diadaptasi ke bahasa Indonesia dan memiliki reliabilitas serta validitas yang memadai untuk mengukur kecemasan kompetitif. Data dianalisis dengan statistik deskriptif menggunakan distribusi frekuensi, persentase, dan nilai rata-rata. Hasil penelitian menunjukkan bahwa rata-rata tingkat kecemasan pemain sebesar 41,48 yang termasuk kategori rendah. Distribusi klasifikasi memperlihatkan 24,14% pemain memiliki kecemasan sangat rendah, 27,59% rendah, 37,93% tinggi, dan 10,34% sangat tinggi. Temuan ini mengindikasikan bahwa mayoritas pemain mampu mengendalikan kecemasan dengan baik, meskipun sebagian masih menunjukkan gejala kecemasan tinggi. Kesiapan mental pemain Persiwi U-17 relatif terjaga, namun aspek keterampilan teknik dan kondisi fisik tetap perlu diperkuat secara berkesinambungan untuk mendukung performa optimal.
