EFFECT OF THIAMINE TETRAHYDROFURFURYL DISULFIDE (TTFD) ON PHYSICAL FITNESS CHIEFLY ON MUSCLE STRENGTH / 体力科学

ABSTRACT

The effect of TTFD chiefly on muscle strength in athletes, mainly track and field, in training camp was examined. The double-blind method was used. The test group (T-group) was given 150mg/day of TTFD while the control group (P-group) was given 3mg/day of TTFD. The duration of administration was two weeks. The following results were obtained.<BR>1) In the following test items, T-group (150mg/day) showed higher values than P-group (3mg/day) in a significant difference<BR>sargent test (morning) at 5% level<BR>sargent test (evening) at 2.5% level<BR>left grip strength (evening) at 5% level<BR>right grip strength (morning) at 10% level<BR>No significant differences were found in other test items.<BR>2) In the P-group, difference between 2 week stage (non-treated period) and 4 week stage (treated period) was observed to have a trend for decline in the various test items. On the contrary, in the T-group, no decline was observed and a trend for a rise was found in all test items.<BR>3) No adverse effects attributable to TTFD were noted with administration of 3mg/ day nor 150mg/day for 2 weeks.<BR>4) The influence of administration of TTFD 150mg/day was discussed on effectiveness of training as shown by the increase of motor ability.
