The Effects of Red Spinach Extract on Physical Performance Following Chronic Resistance Training in Trained Males

Red Spinach is a natural food which is a rich source of nitrates, which are beneficial in hemodynamics, cardiovascular function, and have natural hypotensive and antianginal effects . In recent research, Red spinach extract has been shown to be beneficial in acute exercise performance. However, currently it is unclear how these acute increases in performance may translate to long term training adaptations.

This research study is designed to measure the effects of red spinach extract (RSE) on markers of physical performance, body composition, and health following chronic resistance training and anaerobic exercise.

About this study

The investigators aim to measure muscle strength, athletic performance, body composition, and muscle size in two groups of adults before and after 11 weeks of intervention in a randomized, double blinded study. One group (n=15 ) will receive an intervention of resistance exercise and a Red Spinach Extract supplement, and the other group (n=15) will receive resistance exercise and a placebo (maltodextrin).

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • 18-35 years old
  • At least 1 year of resistance training experience
  • Are free of musculoskeletal injuries
  • Are not taking medications that may interfere with study measurements

Exclusion criteria

  • Participant that cannot take either the RSE or placebo supplement will be excluded, as this will be a double-blind study.
  • Furthermore, participants that cannot participate in pre- and post-research testing, and/or those that cannot commit to regular training sessions will be excluded.
  • Inability to perform physical exercise (determined by health and activity questionnaire)
  • Taking any other nutritional supplement or performance enhancing drug.
  • Any chronic illness that causes continuous medical care.

Treatment and study plan

Placebo

Dietary Supplement

Oral placebo capsules will be taken consisting of maltodrextrin daily for 11 weeks

Red Spinach Extract (RSE)

Dietary Supplement

Oral capsules containing 2g of Red Spinach Extract will be consumed daily for 11 weeks

Primary outcomes

  1. Muscular Strength

    Time frame: 11 weeks

    Muscular strength will be assessed via bench press 1-repetition maximum

  2. Muscular Hypertrophy

    Time frame: 11 weeks

    Muscle thickness of the Rectus femoris and vastus lateralis will be assessed via ultrasonography. Thickeness will be reported in cm.

  3. Body Composition

    Time frame: 11 weeks

    Lean Body Mass, Fat Mass, and Bone Mineral Content will be assessed via Dual X-ray absorptiometry (DXA)

  4. Wingate Anaerobic (WnT) Cycle test performance

    Time frame: 11 weeks

    A 30-second WnT test will be used to assess Average power, peak power, and fatiuge index
