Increasing the Impact Force of the Rear Hand Punch

Shoulder function and scapular position in boxers

“…Supporting Whiting et al (1988), boxers are commonly instructed to avoid "loading" punches as the process can alert an opponent to an incoming strike (Slack, 2013). Turner et al's (2011) position is correct), which would in part explain the resemblance of our finding to that found by other researchers looking at overhead throwing sports (see figure 3). Similarities between punching and overhead throwing may exist (i.e.…”

“…Turner et al (2011) (Whiting, Gregor, & Finerman, 1988) 3D path trajectories show no apparent preload in jabs or hooks. If Turner et al (2011) is incorrect in their preload theory then it is possible that repeated high velocity anterior movements alone are responsible for microtrauma which results in anterior capsule laxity and an increased risk of upper limb injury (Bigliani et al, 1997).

Achilles Tendinopathy and the 100-Pound Punching Bag

“…One's feet positions are in constant flux along with one's weight distribution. The force to punch a bag starts at the ground, the ground reaction force, with leg drive being in both vertical and horizontal directions [41,42]. Turner elaborates, "Each punch involves triple extension whereby the ankle, knee, and hip extend to generate force from the ground" [43].…”
