It is important to continue to expand the biomechanical profile of midfoot function beyond kinematics and include kinetic measurements, such as power. As the external measurements of power are representative of internal energy generating mechanisms, 1 incorporating kinetics into the biomechanical

stationary cycling performed over 10 to 12 weeks led to a reduction in knee pain and stiffness, and improvement in walking speed and distance in individuals with knee OA. 8 , 9 Positive benefits of rehabilitation caused by cycling could be attributed to improvements in leg muscular power output and dynamic

professional rugby league players. 12 – 15 Well-developed acceleration (over a 10-m sprint) and lower-body muscle power were associated with superior tackling ability in elite junior and professional rugby league players. 12 – 14 Furthermore, maximal squat and bench press, as well as peak power of a

It is well established that success in sprint-based activities is greatly influenced by an athlete’s ability to produce high-power output. 1 , 2 This also applies to the winter Olympic sport of skeleton, as lower-limb power is a key determinant of a fast push-start, 3 , 4 which is considered to

Increasing power output is important when training athletes. Power is the product of force and velocity; therefore, changes in velocity are reciprocal for power. 1 During traditional resistance training, repetitions are performed continuously, without rest, until the set is complete. Within

Optimizing muscle power and rapid force production is important for peak performance in several sports. 1 , 2 Weightlifting movements such as the power clean (PC) closely mirror many unloaded athletic movements as they are ballistic and biomechanically similar to jumping, sprinting, and change of

A cyclist’s steady-state velocity during time trial events in track cycling depends on the balance between power production and power losses. In order to improve performance, athletes train to increase power production and try to minimize power loss. This loss of power depends on rolling resistance

from male cyclists to their female counterparts. For instance, lower whole-body muscle mass 16 has been observed in female compared with male athletes, which can influence peak power output, 17 whereas a slower rate of force production during a maximal sprint, irrespective of muscle mass, has been

; Lim, Huang, Wu, Girardi, & Cammisa, 2007 ). PD also leads to changes in gait power profiles at the ankle, knee, and hip, which account for reduction in stride length and gait speed ( Lim et al., 2007 ; Morris, Huxham, McGinley, Dodd, & Iansek, 2001 ; Sofuwa et al., 2005 ; Winter, 1987 ). Growing

-the-ball tackling ability and match-play performance. However, to date, no study has investigated the relationship between an over-the-ball tackle ability drill and rugby league match-play tackle performance. Lower- and upper-body strength, as well as upper-body power, has been shown to be significantly related to
