The study of influence of fencing handle type and handle angle on wrist for a fencing game

Abstract

A long-term use of ina pp ro p riate handle t yp e and poor handle angle ma y result in cumulative trauma disorders (CTDs) for wrist es p eciall y during fencing. This research evaluated the influences of handle t yp es on workload of muscle strength distributed to the wrist during a fencing game via the EMG data. Subsequently, use different angle of handles to evaluate the fatigue p erformance on wrist as well as p re-and p ost-ex p eriment grip difference. The results show that the handle t yp e will affect fencers' muscle strength distributed to the wrist. Itshows that a viscounti-t yp e handle has equall y strengths for all muscle grou p s. Other t yp es of grip are relativel y eas y to cause muscle fatigue. Different handle angles will not affect on the average workload of the wrist, but it will influence the strength of grasp. The handle angles in 210 and 240 show a vulnerabilit y to fatigue for wrist muscles. We concluded that, for handle t yp e, the viscounti-t yp e handle is more a pp ro p riate with its handle angle at 210 to have better p erformance in effective hit rate and hit accurac y , but lead muscles to be easil y fatigue. A handle angle at 240 shows a p oor p erformance for hit rate and hit accurac y for fencers.

Identification of the most frequent injuries in a variety of fencing competitors: A cross sectional study of fencing clubs in the Northeast tri-state region

“…Out of all the moderate injuries, thirteen participants had 2 or more injuries, eight participants had 3 or more injuries, three participants had 4 or more injuries and one had 5 or more injuries. Severe injuries suffered in decreasing order included: knee (9), lower back (8), ankle (7), elbow (5), shoulder (5), foot (2), wrist (2), hip (2), hands (1), and hamstring (1). From the severe injuries, five participants had 2 or more injuries, one participant had 3 or more injuries and three participants had 4 or more injuries.…”

“…Fencers can also use specialized taping for overuse injuries such as those involving the Achilles tendon, medial tibial, plantar fascia, and lateral epicondyle of the humerus. Correction of incorrect postural alignments, effective wrist and hand manipulation of the weapon, and coordination of fencing attacks [2,7] are other important factors in decreasing injury incidence. The most important body part to address is the knee, as discussed above.…”

Development and assessment of a block machine for volleyball attack training

“…In recent years, a variety of approaches that apply diverse engineering techniques have been adopted to improve exercise skills and to win games in the field of sports. Some of these approaches involve the improvement of training methods and schedules [1,2], development of new equipment [3,4], improvement of existing equipment [5], tactical analysis, and strategic planning [6]. More and more efforts are being put in to enhance sports training using technology [11,[13][14][15], particularly in ball game sports.…”
