Abstract

Latar Belakang: Daya ledak otot tungkai berperan penting dalam olahraga bola voli, terutama dalam teknik smash yang memerlukan lompatan tinggi. Kurangnya daya ledak otot tungkai dapat menghambat performa atlet dan meningkatkan risiko cedera. Latihan Countermovement Jump (CMJ) dan Calf Raise sering dilakukan guna meningkatkan daya ledak otot, tetapi perbandingan efektivitas keduanya masih belum banyak diteliti. Tujuan: Penelitian ini bertujuan untuk mengetahui perbedaan pengaruh Countermovement Jump dan Calf Raise terhadap peningkatan daya ledak otot tungkai pada atlet voli di Yogyakarta. Metode: Penelitian menggunakan desain quasi-eksperimental dengan metode pre-test post- test control group design. Sampel terdiri dari 22 atlet voli SMA Muhammadiyah 7 Yogyakarta yang dibagi menjadi dua kelompok: Countermovement Jump, dan Calf Raise. Latihan dilakukan selama 4 minggu, dengan frekuensi 3 kali dalam 1 minggu. Pengukuran daya ledak otot tungkai dilakukan menggunakan Vertical Jump Test, dengan analisis data menggunakan paired sampel t-test dan independent sample t-test. Hasil: Kedua latihan menunjukkan peningkatan signifikan terhadap daya ledak otot tungkai (p<0,05). Namun, Countermovement Jump memberikan peningkatan lebih besar dibandingkan Calf Raise. Kesimpulan: Countermovement Jump lebih efektif dibandingkan Calf Raise dalam meningkatkan daya ledak otot tungkai pada atlet voli, sehingga dapat direkomendasikan dalam program latihan atlet.

Abstract

Background: Background: VO2 max or maximal oxygen volume is the main indicator of a person's aerobic capacity and has a vital role in athlete performance, especially in soccer. Therefore, developing VO2 max is a key component in modern soccer training programs. Physiotherapy interventions through skipping exercises and interval training are non-pharmacological approaches that can be used to increase VO2 max effectively. Research Objective: To determine the differences in the effects of skipping exercises and interval training on increasing VO2 max in soccer players. Method: This study is an experimental quantitative study with a pre-test and post-test control group design. The sample consisted of 22 male respondents from Baturetno Football School students who were divided into two groups (11 respondents each). The intervention was carried out 3x a week for 4 weeks. VO2 max data were collected using the Multi Stage fitness test (MFT). Statistical tests using Paired Sample T-Test and Independent Sample T-Test. Results: Hypothesis I and II tests using paired sample t-test showed that there was an effect of skipping and interval training on increasing VO2 max in soccer players (P = 0.00 P <0.05). Hypothesis III tests using independent sample t-test showed that interval training had a greater effect than skipping training on increasing VO2 max in soccer players. (P = 0.008 P <0.05). Conclusion: interval training had a greater effect than skipping training on increasing VO2 max in soccer players. Suggestion: Further research is expected to conduct further analysis on other, more varied exercises to increase VO2 max in soccer players

Abstract

Type II diabetes mellitus occurs due to chronic metabolic disorders characterized by elevated glucose levels resulting from insulin resistance. Several factors contribute to increased glucose levels, including age, sex, body mass index (BMI), genetics, and occupation. If blood glucose remains uncontrolled and continues to rise, it can damage other organs and lead to complications. Moderate-intensity aerobic exercise consists of deliberately selected movements performed to music, targeting the aerobic system and carried out at a moderate intensity. In contrast, high-intensity aerobic exercise is a training program that combines moderate- and high-intensity movements to target both the aerobic and anaerobic systems. Both types of exercise aim to reduce blood glucose levels. Objective: This study aims to compare the effects of moderate- and high-intensity aerobic exercise on blood glucose levels in patients with type II diabetes mellitus. Method: This study employed quasi-experimental design with two-group pretest-posttest design. The sampling technique was purposive sampling, involving 16 participants who underwent an exercise program three times a week for four weeks. Group I performed moderate-intensity aerobic exercise, while Group II performed high-intensity aerobic exercise. A glucometer was used as the measurement tool. Results: Hypothesis tests I and II (p < 0.05) showed that both moderate- and high-intensity aerobic exercise had a significant effect on lowering blood glucose levels. Hypothesis test III (p < 0.05) indicated a significant difference between the effects of the two exercise intensities. Conclusion: There is a significant difference in the effects of moderate- and high-intensity aerobic exercise. High-intensity aerobic exercise has a greater effect on lowering blood glucose levels in patients with type II diabetes mellitus. Suggestion: Future researchers are encouraged to expand on this study by incorporating additional variables to provide more valuable scientific insights

Abstract

Kemampuan melompat vertikal mencerminkan daya eksplosif otot tungkai yang berperan penting dalam teknik dasar bola voli, seperti smash, jumping service, dan blok. Daya ledak vertikal ini menentukan efektivitas serangan maupun pertahanan sehingga memerlukan metode latihan yang mampu merangsang sistem neuromuskular secara optimal. Latihan plyometric menjadi pilihan utama karena melibatkan stretch-shortening cycle (SSC) untuk menghasilkan kontraksi otot yang cepat dan kuat. Dua bentuk latihan plyometric yang umum digunakan adalah front cone hops dan drop jump, dengan pola gerak berbeda namun sama-sama bertujuan meningkatkan power tungkai. Penelitian ini bertujuan mengetahui perbedaan pengaruh latihan front cone hops dan drop jump terhadap peningkatan power otot tungkai atlet bola voli. Desain penelitian menggunakan quasi experiment dengan pretest-posttest, melibatkan 16 atlet putra SMA Negeri 1 Sayegan yang dibagi menjadi dua kelompok: kelompok front cone hops dan kelompok drop jump. Program latihan berlangsung selama empat minggu dengan frekuensi dua kali per minggu. Pengukuran power dilakukan menggunakan vertical jump test. Hasil penelitian menunjukkan adanya pengaruh signifikan dari kedua bentuk latihan terhadap peningkatan power otot tungkai (p<0,05). Perbandingan antar kelompok juga menunjukkan perbedaan signifikan (p<0,05), dengan drop jump lebih unggul dalam meningkatkan daya ledak vertikal. Dengan demikian, kedua latihan efektif, namun drop jump lebih direkomendasikan.

Abstract

Background: Agility plays a crucial role in the performance of badminton athletes, with the ability to change direction quickly and efficiently. A decline in agility in young athletes often arises from monotonous training programs without specific directional change stimulation. Hurdle drill and cone drill interventions are needed to improve neuromuscular coordination and leg muscle strength. However, the relative effectiveness of both on badminton athletes has been minimally researched. Objective: This study aims to determine the effect of hurdle drill and cone drill training on improving agility in badminton athletes, as well as the differences in their effects. Methods: This study used an experimental design with a two-group pretest-posttest design. The sample consisted of 26 badminton athletes aged 7-11 years at the PB Fury Sport Yogyakarta Club, selected using purposive sampling and divided into two groups (13 people each). Group I was given hurdle drill training and Group II was given cone drill training, with a frequency of 3 times a week for 3 weeks. Agility measurements were taken using the Illinois Agility Test before and after the intervention. Results: The paired sample t-test results showed p=0.000 (p<0.05) in Group I and p=0.000 (p<0.05) in Group II, indicating a significant increase in agility in both groups. However, the independent sample t-test showed p=0.918 (p>0.05), indicating no significant difference between the two exercises. Conclusion: Both exercises were effective in improving agility in badminton athletes
