# Relationships between Anthropometric and Strength Profiles of Streetlifting Athletes
## 2 Materials and Methods
### Anthropometric and Performance Assessments  
A portable stadiometer (GPM, Zurich, Switzerland) and a scale (digital scale, Seca877; Seca, Leicester, UK) were used to measure the height and body mass of the athletes. As suggested by [PERSON] and [PERSON] [12; 13], six body girths (flexed and tensed arm, forearm, chest, hip, thigh and calf), five body breadths (humerus, femur, biacromial and bi-iliaorestal) and four lengths (arm, forearm, tibia and femur) were measured using a flexible tape and a large and small sliding caliper (GPM calipers, Zurich, Switzerland), respectively. Flexed and tensed arm girth was assessed during maximum contraction at the point of maximum girth with the arm raised anteriorly to the horizontal and the elbow flexed at 90\({}^{\circ}\). Forearm girth was measured at the point of maximum girth of the forearm with the subject holding the palm upwards and the arm muscles relaxed. Chest girth was measured at the midpoint of the articulation of the fourth rib with the sternum at the end of normal breathing. Hip girth was measured at the level of the iliac crest in the standing position. Thigh girth was measured between the midpoint of the inguinal crease and the proximal edge of the patella. Calf girth was measured in sitting position at the widest point [13]. Biepicondyl humerus breadth was measured between the medial and lateral epicondyles of the humerus with the arm raised anteriorly to the horizontal and the elbow flexed at 90\({}^{\circ}\). Biepicondyl femur breadth was assessed by measuring the distance between the medial and lateral epicondyles of the femur in a relaxed position. Biacromial breadth was measured between the two acromial processes with the participant standing in a relaxed position with the arms at the side of the body. Bi-ilicorestal breadth was measured between the most lateral points of the iliac tubercles crests [12]. Upper arm length was measured from the superolateral aspect of the acromion to the posterior surface of the olecranon process of the ulna. Forearm length was measured from the most posterior point above the olecranon to the most distal palpable point of the styloid process of the radius. Upper arm and forearm length were measured with the elbow bended at 90\({}^{\circ}\) and the forearm parallel to the ground. Femur length was measured from the inguinal ligament point to the proximal patella edge. Tibia length was measured from the most superior point on the medial border of the head of the tibia and the most superior point on the medial border of the head of the tibia [12]. Six skinfolds (triceps, abdominal, subscapular, supraspanale, medial calf and front thigh) were measured on the left side of the body, using a skinfold caliper (Cambridge Scientific Industries, Cambridge, MA, USA). The triceps skinfold was assessed on the posterior surface of the arm, at the mid-line between the most lateral part of the acromial border and the lateral border of the head of the radius. The abdominal skinfold was raised 3 cm on the left and 1 cm below the belly button. The subscapular skinfold was raised 2 cm below the inferior angle of the scapula. The supraspanale skinfold was assessed just above the iliac crestal site. The medial calf skinfold was assessed in sitting position on the most medial aspect of the calf at the level of the maximal girth. The thigh skinfold was taken in the midpoint of the distance between the inguinal ligament and the superior border of the patella [13]. Each assessment was repeated twice and the intra-operator measurements error was set to <5% for all skinfolds and <1% for girths, breadths and lengths, in accordance with the previous literature [14]. Only the maximum valid load lifted in each exercise during the competition was registered and used for the subsequent data analysis. Athletes had 3 attempts to lift the maximum weight possible during the competition with 10 min of rest between attempts. The order of the streetlifting exercises performed during the competition was as follows: muscle-up, chin-up, dip, and squat.
