  Purpose
The investigators hypothesis is that the infrared-LED illumination during treadmill training can enhance physical performance in postmenopausal women. The basis for such a hypothesis is based on the fact that the light therapy during the intense metabolic stage caused by exercise may be more efficient.

Condition Intervention Phase
Healthy Device: Photon stimulation by light-emitting diodes (LEDs) Other: Treadmill training Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Factorial Assignment

    Progressive aerobic exercise testing on treadmill (Modified Bruce Protocol)

  • Isokinetic concentric exercise testing [ Time Frame: Baseline, 6 months and 12 months ]
    Peak torque, power, work, and fatigue of the dominant quadriceps were measured using the isokinetic dynamometer

  • Biochemical tests [ Time Frame: Baseline and 6 months ]

Arms Assigned Interventions
Experimental: LED Group
Phototherapy associated with treadmill training
Device: Photon stimulation by light-emitting diodes (LEDs)
Treadmill training with the application of the phototherapy was performed twice a week for 6 months, each session lasting 45 min at intensities between 85% and 90% maximal heart rate. The average power and power density on the skin were 100 mW and 39 mW/cm2, respectively. The treatment time was 45 min bilaterally in both thighs. These parameters led to an approximate fluence of 108 J/cm2.
Active Comparator: Exercise Group
Treadmill training
Other: Treadmill training
Treadmill training without the application of the phototherapy was performed twice a week for 6 months, each session lasting 45 min at intensities between 85% and 90% maximal heart rate
No Intervention: Sedentary Group
Neither physical training nor phototherapy

Detailed Description:
Phototherapy improves cellular activation via absorption of photons by chromophores present in the protein components of the mitochondrial respiratory chain - mainly NADH dehydrogenases and cytochrome C oxidase, which leads to increased electron transport, production of ATP, and tissue regeneration (skin, muscle, bone, and nerves). Moreover, phototherapy stimulates the anti-inflammatory effect with analgesia and vasodilatation. Regarding body aesthetics, phototherapy increases microcirculation, lymphatic drainage, as well as collagen synthesis for the treatment of cellulite. The objective of this study was to develop and evaluate the effects of a new clinical procedure: infrared radiation originated from LEDs associated with treadmill training in postmenopausal women. LED arrays were developed for an irradiation of a large area, such as hip and quadriceps muscles, main actuators during stance and swing phases. These body parts are furthermore areas where there is incidence of osteoporosis, mainly at the femur, localized fat deposits, and cellulite. Infrared radiation (850 nm) was selected because this spectral range shows better skin penetration compared to red interval.
