ABSTRAK Ruang Lingkup dan Cara Penelitian: Dalam bidang kardiologi untuk menilai fungsi jantung sering digunakan pembebanan. Biasanya dilakukan pembebanan dalam bentuk kerja isotonik. Pada keadaan dimana tidak dapat dilakukan kerja isotonik, dapat dilakukan pembebanan dengan kerja isometrik (handgrip test) untuk menilai fungsi jantung. Penelitian ini bertujuan untuk mengetahui pengaruh pembebanan kerja isometrik dan isotonik yang sesuai terhadap fungsi ventrikel kiri dengan STI dan konsumsi oksigen miokardium dengan Tri-produk yang menimbulkan peningkatan frekuensi jantung yang sama. Pemeriksaan dilakukan pada 50 pria sehat, usia 20-25 tahun terhadap STI (QS2, LVET, PEP dan ratio PEP/LVET), tekanan darah dan Tri-produk (FJ x TD rata-rata x LVET) dalam keadaan istirahat, waktu kerja isometrik (handgrip test) dan kerja isotonik (ergometer sepeda). Hasil penelitian dianalisis secara statistik. Hasil dan Kesimpulan: Terdapat pemendekan bermakna (p<0,05) pads lamanya QS2, LVET dan PEP pada kedua jenis kerja dibandingkan istirahat. Pemendekan QS2 dan PEP waktu kerja isotonik lebih besar secara bermakna (p<0,05) dibandingkan kerja isometrik, sedangkan pemendekan LVET waktu kerja isotonik tidak berbeda bermakna (p>0,05) dibandingkan kerja isometrik. Tidak terdapat perubahan pada fungsi ventrikel kiri yang dinilai dari ratio PEP/LVET waktu kerja isometrik dibandingkan kerja isotonik. Tekanan darah sistolik, diastolik dan rata-rata waktu kerja isometrik lebih besar secara bermakna (p<0,05) dibandingkan kerja isotonik. Tidak terdapat perbedaan bermakna {p>0,05) antara tekanan darah diastolik waktu kerja isotonik dibandingkan istirahat. Tri-produk waktu kerja isometrik adalah rata-rata 30% lebih besar dibandingkan kerja isotonik dengan peningkatan frekuensi jantung yang sama, hal mans menatakan bahwa pembebanan jantung dengan kerja isometrik cukup berat dan dapat digunakan untuk menilai fungsi jantung.

ABSTRACT Evaluation Of The Left Ventricular Function And Myocardial Oxygen Consumption During Isometric Work By Way Of Measurement Of Systolic Time IntervalsScope and Method of Study: Loading the heart during the evaluation of its function is a frequently used method. Usually the heart is loaded by isotonic work, like the ergo cycle or the treadmill test. But in cases where isotonic cannot be performed, loading the heart with isometric work (handgrip test) can also be used. The purpose of this research work is to examine the effect of isometric and isotonic work of equivalent intensity on the left ventricular function and on the myocardial oxygen consumption as evaluated respectively by the STI and Tri-product. Examination of the STI (QS2, LVET, PEP and PEP/LVET), heart rate, arterial blood pressure and tri-product were performed on 50 young males, age 20 - 25 years, at rest and at the end of isometric work (handgrip test) and isotonic work (ergo cycle). The results are statistically analyzed. Findings and Conclusions: A statistically significant (p 4 0.05) decrease in the duration of Q52, LVET and PEP is found during both kinds of work when compared to values at rest. The decrease in QS2 and PEP during isotonic work is greater as compared to those during isometric work, which is statistically significant (p 4 0.05). However, the duration of LVET during both kind of work. does not differ significantly. There is also no statistic-ally significant difference in the left ventricular function as evaluated by PEP/LVET between the two kind of work. The rise in systolic, diastolic and mean blood pressure is higher during isometric work as compared with isotonic work, which is statistically significant (p < 0.05). There is no significant difference in the diastolic blood pressure during isotonic work and rest (p > 0.05). The tri-product calculated for isometric work is on the average 30 % higher than for isotonic work, which means that loading the heart with isometric work will be sufficiently high for the purpose of evaluating the performance of the heart.

Latihan isometrik kuadrisep dan Jalan kaki dapat menjadi alternatif latihan pada pasien OA lutut untuk mengurangi keluhan nyeri. Penelitian ini bertujuan untuk mengidentifikasi perbandingan efektifitas jalan kaki dan latihan isometrik kuadrisep terhadap nyeri dan rentang gerak sendi pada pasien dengan osteoartritis lutut. Desain penelitian menggunakan quasi-experimental design dengan pendekatan non equivalent control group before - after. Jumlah sampel terdiri dari 17 responden pada masing-masing kelompok dengan teknik consecutive sampling. Hasil penelitian menunjukkan bahwa latihan jalan kaki efektif menurunkan nyeri dan meningkatkan rentang gerak sendi pasien OA lutut p 0.000. Latihan isometrik kuadrisep efektif menurunkan nyeri dan meningkatkan rentang gerak sendi fleksi lutut pasien OA lutut p 0.000. Namun setelah dibandingkan kedua latihan tersebut menunjukkan bahwa latihan jalan kaki tidak lebih efektif menurunkan nyeri dan meningkatkan rentang gerak sendi fleksi lutut daripada latihan isometrik kuadrisep pada pasien OA lutut p 0.000. Perlu dibuat protap latihan jalan kaki dan latihan isometrik kuadrisep yang terprogram. Pasien dengan obesitas dan derajat OA sedang bisa diarahkan dengan pilihan latihan isometrik kuadrisep. Sedangkan pasien dengan berat badan normal atau indeks masa tubuh kurang dan OA derajat ringan, bisa diarahkan pada latihan jalan kaki, serta pemberian edukasi gaya hidup agar kualitas hidup menjadi lebih baik. ...... Pain is known as the main symptom of Osteoarthritis OA which affect on the functional impairment and patient rsquo s quality of life. Alternatively, isometric quadriceps exercise and walking exercise could be employed to reduce the pain among knee OA patients. This study aimed to identify the comparison between walking exercise and isometric quadriceps exercise on pain and joint range of motion in knee osteoarthritis patients. This research was used quasi experimental with non equivalent control group before - after design. The experimental and control group, involved 17 respondents respectively with consecutive sampling technique. The results showed the walking exercise is significantly reduce pain and increase knee flexion range of motion p 0.000. Similarly, the isometric quadriceps exercise is significantly decrease pain and increase knee flexion range of motion p 0.000. Nevertheless, after being compared showed that walking exercise is no more effective reduce pain and increase knee flexion range of motion rather than isometric quadriceps exercise in knee osteoarthritis patients. A standard operational procedure for walking exercise and isometric quadriceps exercise is programmed. Patients with obesity and moderat OA can be directed by choice of isometric quadriceps exercises. While patients with normal weight or less body mass index and mild OA, can be directed to walking exercise, as well as providing lifestyle education for better quality of life.
