Velocity-Based Training in Football

Validity and reliability assessment of 3-D camera-based capture barbell velocity tracking device

“…The 5 increasing resistances in each exercise were determined with intent to induce a range of velocity and power outputs. Using a percentage of a 1RM, the weights of each of the 5 sets were established so that the basic velocity zones would coincide with those proposed by Mann et al 3 The resistances were set at 15-, 35-, 55-, 75-, and 85% of the 1RM for 5 of the 6 exercises. The JS weights were set at 10-, 20-, 30-, 40-, and 50% of the 1RM BS weight.…”

“…2 However, some have pointed to these traditional methods as lacking adaptability or flexibility to variations in the training capacity of a given athlete on a given day. 1,3 Recently, manipulation of the weighted resistance to affect the velocity of the movement in order to elicit a desired training response has grown in popularity, particularly relating to sport performance. 3 Adoption of this variable as the primary means of training prescription, as opposed to absolute load, is termed Velocity Based Training (VBT).…”

“…7,10 Additionally, accelerometers attached to the bar have shown to be a practical and portable method of monitoring barbell kinematics during training. 3,9,11 However, due to many practitioners' and researchers' desire to assess a variety of movements with greater convenience, new devices have entered the market. The strength and conditioning field has seen an influx of camera-based systems and apps purported to measure velocity of a given barbell movement.…”
