简要总结
The aim of the proposed project is to investigate the reliability, validity, and usefulness of the 30-15 intermittent fitness test in the Slovenian Armed Forces. We will compare the results obtained from a continuous treadmill running test, 2-mile run test, and 30-15IFT.
详细描述
Since the ability to perform military tasks depends on the physical fitness of soldiers (PF), one of the most commonly measured PF components during routine physical examinations is cardiorespiratory fitness (CRF). There are several tests used to measure CRF in the armed forces. Because of its simplicity, the most commonly used test of CRF is the 2-mile run test, but it has its own limitations when it comes to specificity of battlefield requirements, training prescription and optimization, and estimation of Vo2max. In combat situations, soldiers rarely run long distances on the battlefield. Therefore, the 2-mile run test does not appear to represent any specificity of combat. Furthermore, based on the data collected from this test, it is difficult to prescribe and optimize a training program for an individual subject. Therefore, the goal of the proposed project is to investigate the reliability, validity, and usefulness of the 30-15 intermittent fitness test in the Slovenian Armed Forces.

研究组 & 干预措施
Continous Treadmill Running Test
One of the four testing conditions the subject will be allocated to is a Continous Treadmill Running Test. Vo2max will be measured by using A K4 b2 a portable gas analyzer (COSMED, Italy). The device provides reliable values for oxygen uptake (VO2), carbon dioxide production (VCO2), and pulmonary ventilation (VE) breath by breath. In addition, blood samples (20 μL) were collected from the earlobe for both tests (before, immediately after, 3 min after, and 5 min after the test) and the samples will be analyzed for blood lactate concentration ([LA-]).

30-15 Intermittent Fitness Test - first trial
Aerobic capacity will be measured using the field-based 30-15IFT test. This intermittent, incremental test consists of 30-second shuttle runs interspersed with 15-second active recovery periods. Running speed will be set at 8 km/h for the first 30-second run and increased by 0.5 km/h in each 30-second phase thereafter. The speed of the last successfully completed stage will be recorded as the test result, i.e. the maximum running speed (V) during IFT. Vo2max will be estimated by the following equation:
Vo2max IFT (ml/min/kg) = 28.3 - 2.15G - 0.741A - 0.0357BM + 0.058A X VIFT + 1.03VIFT where G stands for subjects gender, A for age and BM for body mass, respectively.
