They were attempting to use their thumbs for additional leverage in obtaining a better mechanical advantage over their opponents. As the rule stands this may be a legal technique, but the authors advise a rule change or clarification to discourage its use.

He had been in good health until approximately four weeks prior to admission when he began to experience painful muscular fatigue and stiffness after exercise. This was more marked in the lower extremities and

The previously uninjured feet and ankles of 16 college- age football players were used. All were taped by the same method. A single-tailed paired-sample t-test was done to determine the minimum amount of restriction that could be expected for each motion after the exercise period. Ninety percent confidence intervals between untaped versus taped preexercise, untaped versus taped postexercise, and taped preexercise versus taped postexercise for all motions were determined. Inversion neutral, plantarflexion inversion, and ever sion neutral had an average residual restriction after exercise of 50%, or greater than the initial restriction prior to exercise. Plantarflexion, dorsiflexion, and plantarflexion eversion loosened s...
