Brief Summary

The aim of the present study was to evaluate potential beneficial effects of TTFD® EX PLUS (Prince Pharmaceutical Co., Ltd., Yunlin County, Taiwan) on fatigue and ergogenic functions following physiological challenge. The test used a double-blind crossover design and supplementation for 28 days. 32 male and female 20-30 year-old subjects were divided into two groups in a balanced order according to each individual's initial maximal oxygen uptake and were assigned to receive a placebo with equal gender (non TTFD® EX PLUS with same color/day, n=16, 8 male and 8 female) or TTFD® EX PLUS (600mg/tablet/day, n=16, 8 male and 8 female) every morning. After the intervention, there were 28 days of wash-out, during which time the subjects did not receive further interventions.

Outcome Measures

Primary Outcomes (5)

  • Exercise endurance exhaustion time

    Investigators adopted a double-blind test in which the volunteers, based on their basal maximal oxygen consumption (VO2max). before and after intervention, the individual basal VO2max during pretest was used as a reference to adjust the individually appropriate exercise intensity to measure exhaustive endurance (85% VO2max) and recording the running time from begin to exhaust.

    28 days

  • Clinical Biochemistry of lactate level

    For assessment of fatigue-related indices, volunteers fasted for at least 8 h before the 60% VO2max fixed intensity exercise challenge. Blood samples were collected with an arm venous catheter at indicated time points during exercise and recovery periods, including baseline (0), 5 (E5), 10 (E10), 15 (E15), and 30 (E30) min during the exercise phase, and 20 (R20), 40 (R40), 60 (R60), and 90 (R90) min in the recovery phase. Serum lactate (mmol/L), were assessed for monitoring physiological adaptation. All biochemical indices were assessed using an autoanalyzer (Hitachi 7060, Tokyo, Japan).

    28 days

  • Clinical Biochemistry of ammonia level

    For assessment of fatigue-related indices, volunteers fasted for at least 8 h before the 60% VO2max fixed intensity exercise challenge. Blood samples were collected with an arm venous catheter at indicated time points during exercise and recovery periods, including baseline (0), 5 (E5), 10 (E10), 15 (E15), and 30 (E30) min during the exercise phase, and 20 (R20), 40 (R40), 60 (R60), and 90 (R90) min in the recovery phase. Serum ammonia (umol/L), were assessed for monitoring physiological adaptation. All biochemical indices were assessed using an autoanalyzer (Hitachi 7060, Tokyo, Japan).

    28 days

  • Clinical Biochemistry of CK level

    For assessment of fatigue-related indices, volunteers fasted for at least 8 h before the 60% VO2max fixed intensity exercise challenge. Blood samples were collected with an arm venous catheter at indicated time points during exercise and recovery periods, including baseline (0), 5 (E5), 10 (E10), 15 (E15), and 30 (E30) min during the exercise phase, and 20 (R20), 40 (R40), 60 (R60), and 90 (R90) min in the recovery phase. Serum CK (U/L), were assessed for monitoring physiological adaptation. All biochemical indices were assessed using an autoanalyzer (Hitachi 7060, Tokyo, Japan).

    28 days

  • Clinical Biochemistry of glucose level

    For assessment of fatigue-related indices, volunteers fasted for at least 8 h before the 60% VO2max fixed intensity exercise challenge. Blood samples were collected with an arm venous catheter at indicated time points during exercise and recovery periods, including baseline (0), 5 (E5), 10 (E10), 15 (E15), and 30 (E30) min during the exercise phase, and 20 (R20), 40 (R40), 60 (R60), and 90 (R90) min in the recovery phase. Serum glucose (mg/dL), were assessed for monitoring physiological adaptation. All biochemical indices were assessed using an autoanalyzer (Hitachi 7060, Tokyo, Japan).
