Treadmill equipment is possibly the most popular kind of gym equipment with most commercial gyms as well as home gyms incorporating this most basic of fitness machines.

If many manufacturers report increases in the sale of treadmill equipment this is because treadmills facilitate the most basic of exercises – walking, jogging and running, for which no training, or skill is required and which can suit most fitness levels and body types.

Another reason for the popularity of treadmill equipment is that walking is a very effective load bearing (as against cycling that does not let the legs take all the load of the body) exercise that is low impact that can keep a person fit with little effort.

Further, treadmill equipment, unlike other gym equipment such as a multi weight station and so on, can fit along one wall of a room taking up little space.

Treadmills are also very versatile – not only can you increase the level of difficulty of your workout – from walk to jog to run as your fitness levels increase; but you can also increase complexity of your exercise by simulating walking up a slope or incline by making appropriate alterations in the equipment.

Before buying treadmill equipment, consider the following –

Continuous Duty Rating – This is something like the horsepower of the treadmill equipment and the continuous duty rating of 1.2 to 2.5 is what you should be looking for. With a treadmill “peak duty” is less meaningful than this continuous duty.

Treadmill equipment features that you should check out –

• One of the things that can destroy the best fitness intentions is boredom. And walking on a stationary machine each day for a considerable length of time can get really boring. So if a treadmill has several features such as variable incline and speed, preset programs and other add-ons such as a book holder or DVD viewing and so on then it is more likely to retain your interest for longer.
• Features such as a speed and heart rate monitor and an estimated amount of calories burnt indicator can also keep you motivated and interested in your workout. A heart rate monitor will also warn you if you’re overdoing it.
• Also check how comfortable and smooth the treadmill equipment is to use – it should be long enough to accommodate your longest stride and should be heavy enough and sturdy enough to take some rough handling. A wobbly or jerky treadmill is a no-no.
• Another thing to check in your treadmill equipment is the noise level. If the noise is going to jar or irritate, or drown out the music or TV, then obviously it is not a good choice.
• Consider the amount of space you have in the room where you aim to place the treadmill equipment – take a tape measure, in a large showroom it could look a lot smaller than it will in your more modestly sized room. Does it fold up and away when not in use.

Safety Features – Check if the treadmill equipment has console grips, handrails, an emergency stop button and so on.

Varicose veins are most commonly seen in the legs and ankles. They are large, twisted veins that can be seen near the surface of the skin. According to the Mayo Clinic, varicose veins occur when the vein walls are weakened and stretched.

In this condition, the varicose veins can no longer move blood back up towards the heart.

They essentially become too weak to fight the force of gravity and are unable to push blood back up the legs.

This causes blood to pool in the legs and increases pressure on the veins. This ultimately causes the veins to swell.

Sometimes, small blue or red varicose veins can be seen on the surface of the skin. These are commonly known as spider veins because they often resemble a spider’s web.

Are You at Risk?

Varicose veins can be hereditary. They are usually more common in people who are overweight, or who have to stand for long periods of time.

Symptoms of Varicose Veins

Some people feel aching or fatigue in their legs at the end of the day; otherwise, varicose veins often cause no symptoms, other than minor swelling in your feet and ankles.

In more serious conditions, your skin may become dry and itchy. In this case, your skin might break open easily and bleed. These open sores can also take a long time to heal. Also, if blood pools in your legs, your skin can look brownish in that area.

Home Treatment for Varicose Veins

Avoid Tight Clothes

Tight clothes can limit circulation and can help contribute towards varicose veins. Avoid stockings that leave red marks on your legs, tight pants, and tight belts.

Have Supportive Stockings

Regular support panty hose can occasionally help mild symptoms; however, for more serious cases compression stockings may be needed. These can be found at medical supply stores and sometimes require a doctor’s prescription.

Elevate Your Legs

When possible, lie down and elevate your legs above your heart level.  This will assist the blood in your lower extremities to circulate back to your heart.

When sitting, put your legs on a foot stool. Also, avoid crossing your legs while sitting.

Switch Positions Often

Sitting and standing for long periods of time can often contribute to varicose veins. If you have to sit for school or work, try to get up periodically and stretch your legs by walking.

Likewise, if you have to stand for an extended amount of time, try to switch positions frequently and sit down when you can.

Exercise Frequently

Try to get regular exercise by walking, biking, swimming, or whatever activity interests you. Recruiting muscles in your legs will help prevent blood from pooling in your lower extremities.

Exercise will also help keep your body weight down. This will assist in decreasing the amount of direct pressure on your lower extremities.

Medical Treatments for Varicose Veins

The traditional surgical treatment has been vein stripping to remove the involved veins

Newer, less invasive treatments attempt to seal the main leaking vein on the thigh.

Techniques, such as ultrasound-guided foam sclerotherapy, radiofrequency ablation and laser treatment, are available as well.

When to Call a Doctor?

If the skin over varicose veins starts to bleed heavily and doesn’t stop with direct pressure, call your physician.

Furthermore, if your legs swell and become painful, you could have other conditions that may require a physician’s assistance.

Background:
Adipocyte volume (fat accumulation) and cell number (adipogenesis) is increased in obese individuals. Our objective was the identification of dietary constituents with inhibitory effects on triglyceride formation during adipogenesis. Therefore an in vitro adipose cell assay in murine C3H10 T1/2 cells was developed, which enabled rapid quantification of intracellular fat droplet accumulation during adipocyte differentiation. Results were corroborated by expression levels of several specific adipogenic and lipogenic genes which are known to regulate triglyceride accumulation.
Methods:
C3H10 T1/2 adipocyte differentiation was conducted with rosiglitazone in the presence of test compounds for 7 days. Accumulation of intracellular lipid droplets was measured using the Cellomics(R) ArrayScan(R) VTI HCS reader and SpotDetector(R) BioApplication from ThermoFisher. Fluorescent images were automatically acquired and analysed employing the fluorescent dyes BODIPY(R) 493/503 and Hoechst 33342, for staining neutral lipids and localisation of nuclei, respectively. The expression levels of adipogenic and lipogenic genes, such as PPAR alpha and PPAR gamma, C/EBP alpha, aP2, adiponectin, LPL and HSL, CPT-1 beta, ACC1, Glut4 and FAS, were determined by quantitative RT-PCR. Dietary ingredients including PUFAs, carotenoids, polyphenols and catechins were tested for their effect on lipid accumulation.
Results:
The omega-3 PUFAs docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), the carotenoid beta-carotene and hydroxytyrosol exhibited the strongest inhibitory effects on the rosiglitazone- stimulated lipid formation. (all-E)-lycopene and epigallocatechin gallate (EGCG) showed a moderate inhibition, whereas resveratrol did not reduce fat droplet formation. Additionally, it was demonstrated that adipogenic and lipogenic gene expression was attenuated. DHA, beta-carotene and hydroxytyrosol inhibited the gene expression of PPAR gamma, C/EBP alpha, aP2 and CPT-1 beta.
Conclusion:
This in vitro assay in differentiating adipocytes enables automated detection and quantification of changes in lipid droplet number, size and intensity. The observed inhibitory effects of identified dietary constituents such as omega-3 PUFAs and beta-carotene correlate with the modulation of genes involved in adipocyte differentiation.

Background:
A remarkable range of biological functions have been ascribed to resveratrol. Recently, this polyphenol has been shown to have body fat lowering effects. The aim of the present study was to assess some of the potential underlying mechanisms of action which take place in adipose tissue.
Methods:
Sixteen male Sprague-Dawley rats were randomly divided into two groups: control and treated with 30 mg resveratrol/kg body weight/d. All rats were fed an obesogenic diet and after six weeks of treatment white adipose tissues were dissected. Lipoprotein lipase activity was assessed by fluorimetry, acetyl-CoA carboxylase by radiometry, and malic enzyme, glucose-6P-dehydrogenase and fatty acid synthase by spectrophotometry. Gene expression levels of acetyl-CoA carboxylase, fatty acid synthase, lipoprotein lipase, hormone-sensitive lipase, adipose triglyceride lipase, PPAR-gamma, SREBP-1c and perilipin were assessed by Real time RT-PCR. The amount of resveratrol metabolites in adipose tissue was measured by chromatography.
Results:
There was no difference in the final body weight of the rats; however, adipose tissues were significantly decreased in the resveratrol-treated group. Resveratrol reduced the activity of lipogenic enzymes, as well as that of heparin-releasable lipoprotein lipase. Moreover, a significant reduction was induced by this polyphenol in hormone-sensitive lipase mRNA levels. No significant changes were observed in other genes. Total amount of resveratrol metabolites in adipose tissue was 2.66+/-0.55 nmol/g tissue.
Conclusions:
It can be proposed that the body fat-lowering effect of resveratrol is mediated, at least in part, by a reduction in fatty acid uptake from circulating triacylglycerols and also in de novo lipogenesis.

Background:
Chromium (Cr) is an essential trace element that has garnered interest for use as a weight loss aid, but its molecular mechanism in obesity is not clear. In this study, an attempt has been made to investigate the effects of chromium histidinate (CrHis) on glucose transporter-2 (GLUT-2), nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), nuclear factor-kappa B (NF-κB p65) and the oxidative stress marker 4-hydroxynonenal adducts (HNE) expressions in liver of rats fed high fat diet (HFD).
Methods:
Male Wistar rats (n = 40, 8 wk-old) were divided into four groups. Group I was fed a standard diet (12% of calories as fat); Group II was fed a standard diet and supplemented with 110 μg CrHis/kg BW/d; Group III was fed a HFD (40% of calories as fat); Group IV was fed HFD and supplemented with 110 μg CrHis/kg BW/d.
Results:
Rats fed HFD possessed greater serum insulin (40 vs.33 pmol/L) and glucose (158 vs. 143 mg/dL) concentration and less liver Cr (44 vs.82 μg/g) concentration than rats fed the control diet. However, rats supplemented with CrHis had greater liver Cr and serum insulin and lower glucose concentration in rats fed HFD (P < 0.05). The hepatic nuclear factor-kappa B (NF-κB p65) and HNE were increased in high fat group compared to control group, but reduced by the CrHis administration (P < 0.05). The levels of hepatic Nrf2 and HO-1 were increased by supplementation of CrHis (P < 0.05).
Conclusion:
These findings demonstrate that supplementation of CrHis is protective against obesity, at least in part, through Nrf2-mediated induction of HO-1 in rats fed high fat diet.
