Brief Summary

The potential benefits of exercise for the treatment of chronic inflammatory diseases and pain have been well documented in the scientific literature. Psychiatric, neurological, metabolic and cardiovascular diseases are examples of conditions that impact the health and quality of life of the population. Due to the effects provided by exercise, it can modify the natural course of these diseases. This concept is important to justify the efforts made by government bodies committed to promoting exercise, such as the WHO. However, the habitual practice of physical activity following the primary guidelines may be hampered by some factors, including those that support the physiological repercussions of exercise on the body, such as muscle pain. In this sense, an important complicating factor such as delayed-onset muscle soreness (DOMS), present in the post-exercise recovery period, can impair adherence and permanence in physical activity programs, thus representing a considerable barrier to exercise promotion. They can also severely impair the performance of high-level athletes. Flavonoids, present in plants, but also in foods of the human diet, are known to have several biological properties, including analgesic, anti-inflammatory, and antioxidant effects. Currently, there are still few studies that have evaluated the effects of flavonoids on the development and evolution of DOMS in humans.

Outcome Measures

Primary Outcomes (1)

  • Muscle soreness

    Evaluated by both digital algometer (in kilograms force; Kgf) and visual analogue (VAS) scale (in centimeters; cm), where 0 represents no pain and 10 the worst possible pain.

    Basal, 24, and 48 hours after DOMS induction protocol

Secondary Outcomes (6)

  • Muscle tissue damage through the evaluation of the creatine phosphokinase (CPK) levels.

    Basal, 24, and 48 hours after DOMS induction protocol

  • Plasmatic lipid peroxidation levels

    Basal, 24, and 48 hours after DOMS induction protocol

  • Plasmatic total antioxidant status

    Basal, 24, and 48 hours after DOMS induction protocol

  • Recovery of muscle function through the evaluation of the average and maximum torque of the knee extension for determining quadriceps strength (maximum voluntary isometric contraction; MVIC).

    Basal, 24, and 48 hours after DOMS induction protocol

  • Recovery of muscle function through vertical jump height.

    Basal, 24, and 48 hours after DOMS induction protocol.

  • +1 more secondary outcomes

Study Arms (2)

Intervention (placebo, corn starch tablets)

EXPERIMENTAL

Treatment will occur by oral route, and everyone will ingest identical opaque capsules (750 mg). The treatment protocol will be applied before the start (pre-treatment) of the intense dynamic exercise sessions, once a day, during the two days before, and on the day (immediately before) the execution of the exercise protocol.

Drug: Placebo

Intervention (diosmin)

EXPERIMENTAL

The treatment protocol will be applied before the start (pre-treatment) of the intense dynamic exercise sessions, once a day, during the two days before, and on the day (immediately before) the execution of the exercise protocol.

Drug: Diosmin750

Interventions

The ingestion will occur orally, under monitoring by the responsible investigator.
