The Benefits of a Trampoline Workout & Rebounding

The AHA! Team — Wed, 03 Sep 2025 05:23:54 +0000

Kyra Oliver via Dr. Axe – Many people first fall in love with trampolines as children, but did you know that a trampoline workout can benefit adults just as much as trampolines bring joy to the little ones? It’s true. In addition to being fun, a trampoline workout, also known as rebounding, has many great health benefits — particularly for your lymphatic system. For instance, did you know that rebounding can burn more calories than walking or jogging? Or that it’s a great way to work your major muscle groups because it allows you to work them through their full ranges of motion? Or that it’s downright fun?! A trampoline workout can also strengthen your body while detoxifying the cells within it. Plus, it’s a low-impact exercise option that’s very easy on the joints — something running can’t match. While you may think the type of large trampolines you seen in backyards may be a bit much, there are small versions that can fit right in your living room and are easy to store. So get ready to jump around and improve your health all at the same time. Read on to learn how to do a trampoline workout and how exactly it strengthens the body. What Is Rebounding? Trampoline and tumbling exercises have been around for a very long time and can be traced to archeological drawings found in ancient China, Egypt and Persia. The firs modern trampolines were developed in 1934 by George Nissen and Larry Griswold at the University of Iowa, according to the official website of the Olympics. Trampolines were originally used to train astronauts and as a training tool for other sports, such as acrobatics, tumbling, diving, gymnastics and freestyle skiing. Eventually, trampolines became so popular to the point of becoming a sport in the Olympic Games. The first Trampoline World Championships took place in 1964, and trampoline was first recognized as a sport in the U.S. in 1967. The double mini-trampoline competition was added in 1978 and began as two individual mini trampolines, separated by a small table covered by a mat. Later, a one-piece unit was developed by Bob Bollinger and is used today as the official equipment for that event. Trampolines have become useful in the understanding of gravity and its effects on exercise. The Journal of Applied Physiology recorded a study by NASA in 1980 on rebounding by testing eight young males ages 19–26. The goal was to understand body acceleration distribution and its relation to how it was created. Here’s what the researchers concluded: The results indicate that, for similar levels of HR and VO2, the magnitude of the biomechanical stimuli is greater with jumping on a trampoline than with running, a finding that might help identify acceleration parameters needed for the design of remedial procedures to avert deconditioning in persons exposed to weightlessness. Trampoline Workout Benefits We all know there are many benefits of exercise, but what are the benefits of rebounding, specifically? Let’s explore. 1. Easy on the Joints Working out on the trampoline, or rebounding, has way less impact on the joints, soft tissue and skeleton. Due to how a trampoline is made, most often using either springs or bungee bands, it absorbs much of the impact at every bounce. G-force The NASA study previously mentioned notes that there seems to be more balance of pressure or force, known as G-force, when on the trampoline. Pressure is more evenly distributed at the ankle, back and forehead when rebounding, whereas when running, the pressure is mostly all placed on the ankles, often causing more frequent injury. That means simply switching to a trampoline workout routine can help naturally reduce joint pain and help you avoid common running injuries. 2. Strengthens Cells and Improves Cardiovascular Development A trampoline workout can provide impressive aerobic exercise benefits by strengthening the heart. When tested, the work required to perform trampoline exercise at equivalent levels of effort was significantly greater while on the trampoline than while running. Increase oxygen uptake When oxygen reaches our cells, it helps strengthen them and provide the ability to endure more exercise efficiently, and because the body is able to increase oxygen uptake when rebounding, versus some other physical activities, it’s possible to get a much better workout. Rebounding can increase oxygen uptake because more oxygen can reach the cells due to the gravity changes that occur when bouncing. In some studies, when testing on the treadmill, the ability to uptake more oxygen was greater when on the trampoline. This could allow participants to perform exercise for longer periods of time. Effects of daily short bouts of trampoline exercise A study regarding the effects of daily short bouts of trampoline exercise during eight weeks on the pulmonary function and the maximal oxygen uptake of children with cystic fibrosis was reported by the International Journal of Sports Medicine. Six girls and two boys with cystic fibrosis, 10–13.5 years of age, participated in a prescribed exercise program on a mini trampoline. The training consisted of three short rounds of trampoline exercise. The study showed that their maximal oxygen uptake (VO2 max) improved during the exercise period. In addition, trampoline exercise programs are suggested as other types of training to add in order to avoid monotony in the training for many patients. 3. Can Improve Immune System Function Due to Lymph Flow Rebounding can lead to increased lymph fluid circulation, which helps boost the immune system by providing a greater white blood cell activity. The lymphatic system is part of your circulatory system and transports a clear, colorless fluid, called lymph, that flushes toxins from your body. It’s believed that there is an increase in the circulation of this fluid when the lymphatic valves are opened during a change in gravitational pull. This particular change occurs upon the moment you land on the trampoline, thanks to gravity. Then, upon leaving the surface, the lymphatic valves are opened. The increased G-force g that occurs when you land causes a surge of lymphatic drainage, which improves circulation and, therefore, may help detoxify your entire system. 4. Helps with Balance Another study reported by the U.S. National Library of Medicine cited the effects of different types of exercise on postural balance in elderly women. These exercises can help prevent functional limitations due to aging, therefore reducing the risk of falls. This study aimed to evaluate the effects of three different exercises: mini trampoline, aquatic gymnastics and general floor gymnastics. Seventy-four physically independent elderly women were randomly assigned to three intervention groups. Each group performed physical training, including cardiorespiratory, muscular strength and endurance, flexibility, and sensory-motor exercises, for 12 weeks. To determine the effects on each intervention group, postural balance tasks were performed. The study concluded that there were significant improvements in the postural balance of elderly women after 12 weeks of training and ultimately provides further evidence that exercise, like a trampoline workout, that includes balance postures can promote health in elderly women. 5. Builds Physical Strength, Muscular Development and Proprioception for Athletes Rebounding is often said to improve physical strength and muscular development as well as proprioception, which is the ability to sense the position, location, orientation and movement of the body and its parts. A study published in the International Journal of Preventative Medicine randomly divided 20 patients with Parkinson’s disease “into two equal groups of weight-bearing exercises and rebound exercise with no significant differences in age, weight, and height.” They compared results on range of motion, proprioception and quality of life after eight weeks. The researchers found that both groups saw significant improvements in all three areas, but the improvement rate was greater across the board in the rebounding therapy group. How to Choose a Good Rebounder Because many injuries can occur while on a trampoline, it’s critical that you don’t go the cheaper route because cheaper trampolines tend to break or malfunction, causing injury. They also can lack the support needed to be effective. It’s important that your rebounder has at least 32 springs that taper at the end. This provides the proper flexibility and a more even bounce. Steel construction lasts longer, too. Some models offer support bars, which may be useful, especially for beginners or the elderly. How to Start Using Your Rebounder Rebounders, or mini trampolines, can be used almost anywhere indoors or outdoors. Remember to start slow with small jumps, and make sure you get used to the equipment before you increase to bigger jumps. A trampoline workout is one idea for burst training at home. You can include some traditional exercise, such as jumping jacks, to get you started. Rebounding is a great low-impact exercise that’s fun and different. In just 15–20 minutes a day, you can burn calories, gain muscle strength and enhance your balance while improving your immune system — and helping turn on the afterburn effect. Trampoline or Rebounding Workout Time: 20–45 minutes, depending on number of sets performed Warmup: Basic Trampoline Bounce The basic bounce can tone your quads, glutes and calf muscles. Stand on the mini trampoline with your feet shoulder-width apart. Relax your arms and shoulders but with a slight bend at the elbow. Lightly bounce up and down while keeping a slight bend in the knees. Your feet should come just a few inches off the trampoline. Repeat 20–30 times. Rest for 15 seconds, and repeat two more times for a total of three rounds. Main Set: Jumping Jacks A classic, this gets your heart rate up while engaging the inner and outer thighs. Standing with feet together, jump out while extending arms out, up and overhead. Then return to the starting position, and repeat. Perform 30–45 jumping jacks. Planks This plank exercise variation works your entire core. Start in plank position with your forearms in the middle of the trampoline and your feet on the floor (unless your trampoline is large enough for your entire body). Hold the plank position for 20–30 seconds. Release for 10 seconds, and repeat three to four times. High Knees This is a great exercise hack that gets your heart rate moving while working your core muscles. Stand with feet hip distance apart. Raise your right knee, return to start, then raise your left knee. Once you feel comfortable, begin doing it as if you are running in place. Repeat 20 times (one on each side counts as one full rep). Planks to Pushups Advanced Move This exercise works your entire core and provides some upper-body strength in the arms and chest. Keeping abs fully engaged, start in plank position with your forearms in the middle of the trampoline and your feet on the floor (unless your trampoline is large enough for your entire body). Transition to your hands one arm at a time, then do a pushup and return to your forearms for another plank. Make sure that your abs are engaged the entire time. Do this exercise for six to 10 reps. Trampoline Squats Wondering how to strengthen your core? Well, this exercise requires you to engage your core muscles. It strengthens glutes and quads as well as your core if properly engaged. Stand on the mini trampoline with your feet shoulder-width apart and arms at your sides. Jump up, and land in a squat position with your knees bent, butt back and thighs parallel to the ground, like sitting down in a chair. It may be helpful to place your arms straight out in front of you for balance. Return to the starting position, and repeat 15–20 times. At first, you may want to take it slow. Once you have mastered the exercise, you can begin to do it a bit faster with continuous movement similar to a jump squat that you would do on the ground. Repeat the entire set three to four times or as best as possible. Precautions It’s extremely important that children are always supervised when on a trampoline of any sort. The condition and quality of trampolines are critical in preventing injuries. Because there...

Two New Studies Test Quercetin And COVID Outcomes

AHA Publisher — Mon, 18 Oct 2021 07:00:14 +0000

Dr. Joseph Mercola – In an August 21, 2021, newsletter,1 Dr. Michael Murray discussed the use of quercetin for respiratory infection symptoms. In November 2020, he’d suffered a “very mild and brief bout of COVID-19.” He also recounts an anecdotal story of a friend who developed suspicious respiratory symptoms. His friend had been taking a number of supplements said to offer protection, but was still feeling awful. As it turns out, the one thing he’d not taken was quercetin, and as soon as he did, that same day, his symptoms started to dissipate. This experience, Murray says, “is consistent with the results from two clinical trials” that were recently published. Quercetin seems to be a safe, far less expensive, and easier-to-obtain and it works by a similar mechanism, driving zinc into the cells to stop viral replication. Statistical Improvement in Clinical Outcomes In the first study,2 42 COVID-19 outpatients were divided into two groups. One group of 21 patients received standard medical therapy consisting of analgesics and an antibiotic (acetaminophen 500-milligram (mg) to 1,000-mg dose if body temperature was higher than 37.5 degrees C — 99.5 F — with a maximum daily dosage of 3 grams, and 500 mg azithromycin for three consecutive days). The other group of 21 patients received standard therapy plus the equivalent of 600 mg of quercetin per day (divided into three doses) for seven days, followed by another seven-day course of 400 mg of quercetin per day (divided into two doses). The quercetin was used with sunflower lecithin, which has been demonstrated to increase absorption in the gut by as much as 20 times, compared to pure quercetin formulations. The main outcomes being evaluated were virus clearance and symptoms. After one week of treatment, 16 of the 21 patients in the quercetin group tested negative for SARS-CoV-2 and 12 reported that all symptoms had diminished. In the standard care group, only two tested negative and four had partially improved symptoms. By the end of Week 2, the five remaining patients in the quercetin group tested negative. In the standard care group, 17 of the 19 remaining patients tested negative and one had died. “These results are impressive and hopefully additional studies will be conducted on hospitalized patients to see how quercetin might be helpful in more severe cases,” Murray wrote in his newsletter. Can Quercetin Reduce Hospitalizations and Deaths? The second study3 — a prospective, randomized, controlled and open-label trial — gave 152 COVID-19 outpatients a daily dose of 1,000 mg of quercetin for 30 days to evaluate its adjuvant effects in the treatment of early symptoms and the prevention of severe infection. According to the authors: “The results revealed a reduction in frequency and length of hospitalization, in need of non-invasive oxygen therapy, in progression to intensive care units and in number of deaths. The results also confirmed the very high safety profile of quercetin and suggested possible anti-fatigue and pro-appetite properties. QP (Quercetin Phytosome®) is a safe agent and in combination with standard care, when used in early stage of viral infection, could aid in improving the early symptoms and help in preventing the severity of COVID-19 disease. It is suggested that a double-blind, placebo-controlled study should be urgently carried out to confirm the results of our study.” Mechanisms of Action As noted in the first study4 above, quercetin was chosen based on the fact that it has antiviral, anti-blood clotting, anti-inflammatory and antioxidant properties, all of which are important in the treatment of SARS-CoV-2 infection. In the second study, more detailed mechanisms of action are reviewed. According to the authors:5 “SARS-CoV-2 proteases, like 3-chymotrypsin-like protease (3CLpro), papain-like pro-tease (PLpro), RNA-dependent RNA polymerase, spike (S)protein and human angiotensin-converting enzyme 2 (hACE2) are considered possible targets for developing effective anti-COVID-19 drugs. Recently, molecular docking studies have suggested the possible binding interaction of quercetin with the 3CLpro, PLpro, and S-hACE2 complex. Some recent results, obtained by biophysical techniques, appear to support the results of the molecular docking studies. Quercetin, a flavonol not naturally present in the human body, is the most abundant polyphenol in fruits and vegetable and is widely used as a dietary supplement to boost the immune system and promote a healthy lifestyle. Quercetin is characterized by three crucial properties: antioxidant, anti-inflammatory and immunomodulatory. The combination of these actions allows quercetin to be a potential candidate to support all unhealthy conditions where oxidative stress, inflammation and immunity are involved.” Initially, quercetin gained attention because it’s a zinc ionophore, meaning it shuttles zinc — which has well-known antiviral effects — into your cells just like the drug hydroxychloroquine. In particular, quercetin exerts significant inhibition on the binding of specific spike proteins to ACE-2 receptors, thereby blocking the ability of the virus to infect human cells. Quercetin has also been shown to directly neutralize viral proteins the are critical in the replication of SARS-CoV-2. ~ Dr. Michael Murray Some proposed the primary reason hydroxychloroquine and quercetin worked was because of this feature. Of course, you also had to take zinc along with either of them. To effectively act as a zinc ionophore, the quercetin also needs vitamin C. Since then, other studies, including the two reviewed here, have shown quercetin has other actions that makes it useful against SARS-CoV-2 as well. As reported by Murray in his newsletter: “In particular, quercetin exerts significant inhibition on the binding of specific spike proteins to ACE-2 receptors, thereby blocking the ability of the virus to infect human cells. Quercetin has also been shown to directly neutralize viral proteins the are critical in the replication of SARS-CoV-2.” In some studies, quercetin has also been shown to inhibit the release of inflammatory cytokines, which could help alleviate infection-related symptoms and suppress excessive inflammatory responses from occurring. Its antioxidant effects may also help prevent tissue damage caused by scavenging free radicals, thereby aiding in the recovery process of viral infections.6 Quercetin’s Antiviral Properties Quercetin’s antiviral properties have been attributed to three main mechanisms of action: Inhibiting the virus’ ability to infect cells Inhibiting replication of already infected cells Reducing infected cells’ resistance to treatment with antiviral medication For example, research7 funded by the U.S. Defense Advanced Research Projects Agency (DARPA), published in 2008, found it lowers your risk of viral illness such as influenza and boosts mental performance following extreme physical stress, which might otherwise undermine your immune function and render you more susceptible to infections. Here, cyclists who received a daily dose of 1,000 mg of quercetin in combination with vitamin C (which enhances plasma quercetin levels8,9) and niacin (to improve absorption) for five weeks were significantly less likely to contract a viral illness after bicycling three hours a day for three consecutive days, compared to untreated controls. While 45% of the placebo group got sick, only 5% of the treatment group did. Quercetin Works Against Many Common Viruses Before the COVID-19 pandemic struck, several studies had highlighted quercetin’s ability to prevent and treat the common cold and seasonal influenza.10,11,12,13,14,15,16,17,18 By attenuating oxidative damage, it also lowers your risk of secondary bacterial infections,19 which is actually the primary cause of influenza-related deaths. Importantly, quercetin increases mitochondrial biogenesis in skeletal muscle, which suggests part of its antiviral effects are due to enhanced mitochondrial antiviral signaling.20 Quercetin also works against other viruses, as demonstrated in the following studies: • A 1985 study found quercetin inhibits infectivity and replication of herpes simplex virus type 1, polio-virus type 1, parainfluenza virus type 3 and respiratory syncytial virus (RSV).21 • A 2016 animal study22 found quercetin inhibited mouse dengue virus and hepatitis virus. • Other studies have confirmed quercetin’s power to inhibit both hepatitis B23 and C24 infection. • A March 2020 study25 found quercetin provides “comprehensive protection” against Streptococcus pneumoniae infection, both in vitro and in vivo, primarily by neutralizing pneumolysin (PLY),26 one of the toxins released from pneumococci that encourages S. pneumoniae infection to blossom in the first place. Streptococcus pneumoniae is responsible not only for pneumonia, but can also be involved in some ear and sinus infections, meningitis and certain blood infections.27 As reported by the authors of this study:28 “The results indicated that quercetin significantly reduced PLY-induced hemolytic activity and cytotoxicity via repressing the formation of oligomers. In addition, treatment with quercetin can reduce PLY-mediated cell injury, improve the survival rate of mice infected with a lethal dose of S. pneumoniae, alleviate the pathological damage of lung tissue and inhibit the release of cytokines (IL-1β and TNF-α) in bronchoalveolar lavage fluid. Considering the importance of these events in antimicrobial resistant S. pneumoniae pathogenesis, our results indicated that quercetin may be a novel potential drug candidate for the treatment of clinical pneumococcal infections.” How Quercetin Combats Inflammation and Boosts Immunity Aside from its antiviral activity, quercetin is also known for boosting immunity and combating inflammation. As noted in a 2016 study29 in the journal Nutrients, mechanisms of action include (but is not limited to) the inhibition of:30 Lipopolysaccharide (LPS)-induced tumor necrosis factor α (TNF-α) production in macrophages. TNF-α is a cytokine involved in systemic inflammation, secreted by activated macrophages, a type of immune cell that digests foreign substances, microbes and other harmful or damaged components LPS-induced mRNA levels of TNF-α and interleukin (IL)-1α in glial cells, which results in “diminished apoptotic neuronal cell death” The production of inflammation-producing enzymes Calcium influx into the cell, which in turn inhibits pro-inflammatory cytokine release, as well as histamine and serotonin release from intestinal mast cells31 According to this paper, quercetin also stabilizes mast cells, has cytoprotective activity in the gastrointestinal tract, and “a direct regulatory effect on basic functional properties of immune cells,” which allows it to inhibit “a huge panoply of molecular targets in the micromolar concentration range, either by down-regulating or suppressing many inflammatory pathways and functions.”32 Bioavailability While quercetin does have potent antiviral effects, in order for it to work effectively you need sufficiently high dosages to raise the level of quercetin in your body’s tissues. The relatively low absorption rate of quercetin is why a sunflower lecithin formulation was used. Research33 published in the July-December 2021 issue of the Journal of Natural Health Products Research, found a quercertin matrix has the same total absorption rate as quercetin phytosome — and higher peak blood levels. “Since both of these forms of quercetin produce similar blood levels, they should produce the same effects at equal dosages based upon quercetin content,” Murray wrote in his newsletter, adding: “My dosage recommendation as part of a nutritional supplement program to support immune function is 250 mg twice daily. And in patients with active Infection, my recommendation is … six capsules twice a day providing a total of 3,000 mg of quercetin. This high dosage should be taken for at least 10 days and then reduced to a maintenance dosage of 250 mg twice daily … [This] high dosage may not be necessary. But my dosage calculations are based upon likely tissue concentrations needed to exert the strongest antiviral effects. And given the safety of quercetin, there is no harm at this level.” Protocol Using Quercetin One doctor who early brought quercetin into the limelight was Dr. Vladimir Zelenko. As hydroxychloroquine became difficult to obtain, Zelenko switched to recommending quercetin instead, as it’s readily available as an over-the-counter supplement. For a downloadable “cheat sheet” of Zelenko’s protocol for COVID-19, visit VladimirZelenkoMD.com. Other Health Benefits of Quercetin There are also other lesser known benefits and uses for quercetin, including the prevention and/or treatment of:34 High blood pressure35,36 Cardiovascular disease37 Obesity38 and metabolic syndrome39 (a cluster of conditions including high blood pressure, high blood sugar, high triglyceride levels and fat accumulation around the waist that raise your risk for Type 2 diabetes, heart disease and stroke) Certain kinds of cancer, in particular leukemia, and to a lesser degree breast cancer40 Nonalcoholic fatty liver disease (NAFLD)41 Gout42 Arthritis43 Mood disorders44 Aluminum-induced neurodegenerative changes, such as those seen in Alzheimer’s, Parkinson’s and amyotrophic lateral sclerosis (ALS).45 Longevity, thanks to its senolytic benefits (clearing out damaged and worn-out cells)46,47 Research has also highlighted...
