Di dalam permainan futsal, keseimbangan kinerja otot postural dibutuhkan untuk menjaga kestabilan tubuh untuk menerima operan dan memasukkan bola ke gawang tim lain pada saat menyerang, mengubah arah gerakan dengan cepat ketika kembali ke posisi masing–masing serta menghindari gangguan pada punggung..Penelitian ini adalah bentuk penelitian eksperimental yang akan menguji efektifitas dari pemberian trunk balance exercise dalam  meningkatkan  keseimbangan kinerja otot erector spine pada pemain futsal pemula,  pada penelitian ini sampel akan diberikan trunk balance exercise untuk meningkatkan keseimbangan kinerja otot erector spine pada pemain futsal pemula. Penelitian ini dilakukan selama 6 minggu  dan intervensi dilakukan sebanyak 18 kali selama periode penelitian. Sampel diukur dengan surface electromyography dengan mengukur kerja dari otot erector spine kanan dan kiri dengan menghitung proporsi kerja pada otot tersebut , di ukur pada sebelum intervensi kemudian dilakukan intervensi kemudian setelah dilakukan intervensi, sampel di ukur kembali untuk mendapatkan nilai hasil intervensi.Hasil dari pemberian trunk balance exercise menunjukkan nilai rerata pada sebelum perlakuan dengan nilai (83,82±2,94) % dan nilai rerata pada setelah perlakuan sebesar (96,74 ±2,39) %, dengan nilai probailitas pada sampel  adalah 0,000 (p<0,05) dan dinyatakan ada perbedaan yang signifikan pada penelitian tersebut. dan dapat dinyatakan secara analisis statistik ada perbedaan yang signifikan antara sebelum dan sesudah perlakuan yang dilakukan dan artinya pemberian trunk balance exercise dapat  meningkatkan  keseimbangan kinerja otot erector spine pada pengghobi futsal.

High-intensity exercise exercises in the exercise process use enormous amounts of muscle glycocal energy to strengthen adipose tissue into energy acids, energy requirements balanced with oxygen demand that will improve pulmonary performance and physiology. Weight-adjusting exercises are adjusted to the adaptation and physiology of muscles, increased muscle development and physiological muscles and muscles increases into more so that the energy process increases both muscle glycogen and increased fat oxidation. In this study the sample will be divided into 2 groups, group I will be given High intensity interval training, group II will be given Circuit weight training, both groups aim to reduce the percentage of body fat and increase the vital capacity of the lung. This study measures the pre and post test results so that it will be measured before treatment and after treatment after the exercise program for 6 weeks. Samples will be measured using Bioelectrical Impedance Analisys to measure the percentage of body fat and Spirometry to measure vital pulmonary capacity.The results of the first group hypothesis test showed the value before the fat percentage of 21.75 and after training to be 19.46, then before the vital capacity of the lungs 2.32 and after training to 4.02. While in group 2 the fat percentage value was 21.55 and the training was determined to be 19.79. For the value of vital capacity of lung 2.46 and after training to 3.64, with the probability value in both groups was 0.000 which means (p <0.05) and the measurement was no significant difference from both exercises. In the test of hypothesis III the comparison of results in group I , II, t-test independent sample with the result of the average group I fat difference 2.29 ± 0.46, KVparu 1.75 ± 0.55, Group II fat% 1.70 ± 0.43, KVparu 1.17 ± 0.45 with fat% probability value (p = 0,725) and KVparu (p = 0,073) which means (p> 0,05) and can. There was no significant difference between the three interventions.The conclusion of this research is high intensity interval training as well as ciecuit weight training in decreasing body fat percentage and increasing vital capacity of lung
