MAS were calculated as the sum of the power against gravity and the power against rolling friction (friction coefficient = 0.0237) at the respective velocities as described previously. 21 HIT Sessions The HIT sessions were performed at a fixed time of day (±1 h) interspersed with 3 to 5 days

accompanied changes in required power may be of interest. Therefore, minimizing required power for a team or an individual in a team can contribute to a better performance. Aerodynamic drag is caused by moving through air and can be assigned into a certain amount of friction drag and pressure drag, which

, albeit only in 1 direction (adding mass). Finally, additional grip is expected to enhance performance. 7 – 9 It is common practice to use high-friction gloves in wheelchair racing and rugby, but not in wheelchair basketball. Although the use of gloves will probably not find its way into basketball, but

previous research. 10 , 11 A prismatic kinematic pair was used to model the contact between the curling stone and ice (Figure  2 B); rotations about the vertical axis were omitted. The contact model also included dry Coulomb friction. 9 The multibody biomechanical model has 3 degrees of freedom and is

opposing forces caused by road gradient, air resistance, acceleration, and friction. These forces are calculated using 9 different measurements: 3 accelerometers to measure displacements in the x , y , and z directions; frontal air pressure using a small port at the front of the device; environmental

primarily taken up by the ligaments because the friction between the tibia and femur was assumed to be negligible. 35 As the ACL is the primary restraint to anterior translation of the tibia, the posterior tibiofemoral force could correspond to the ACL loading. In other words, the posterior tibiofemoral
