Abstract

The present application relates generally to the field of underwear and undergarments. More particularly, the present application relates to a novel undergarment that induces caloric burn while the person wearing it goes about his or her daily activities. An objective for the underwear is to increase exercise of body muscles used in daily living. In one embodiment, the present application provides a novel undergarment and/or shaper with carefully positioned non-stretch bands, or the equivalent thereof, that are relatively more resistant (i.e., less stretchy or elastic) than the fabric that is used to construct the remainder of the undergarment. These bands have a direct effect on muscles that would normally be activated during regular activity and cause them to be exercised to a further degree, but in a gentle manner. The effect, which in many cases is slightly perceptible, is felt while the wearer goes about his or her daily routine.

Description

WO 2010/102378 PCT/CA2009/001898 CALORIC BURN UNDERGARMENT PRIORITY INFORMATION The present application claims the benefit of United States Provisional Patent Application No. 61/159,575, which is hereby incorporated by reference. 5 FIELD OF THE INVENTION The present application relates generally to the field of underwear and undergarments. More specifically, the present application relates to a novel undergarment or shaper that induces caloric burn when the subject wearing it engages in his or her daily activities. 10 BACKGROUND OF THE INVENTION Undergarments of all kinds abound in the marketplace. In addition to their primary function of covering the wearer's body, a number of undergarments have the added features of being able to shape and/or provide support. More recent garments, such as those manufactured by Wacoal, are designed to enhance sports performance. Wacoal 15 also has a CW-X Series@ of garments that is based on "variable compression technology". These garments are stated to facilitate circulation and venous return, thereby minimizing lactic acid buildup and muscle soreness during and after activity. Undergarments and bottom wear that include design elements that shape the body include girdles or underwear with girdle-like elements. These undergarments 20 function by either binding or compressing specific areas of the body, often with resistant elastic elements that are strategically positioned in selected areas, such as the lower abdomen, to flatten or enhance the profile of the body, or underneath the buttocks to lift and shape this section of the body. Inconveniently, underwear of this type can be uncomfortable for the wearer, as the binding or compressing elements can literally make 25 individuals feel squeezed in. Consequently, individuals wearing such garments will often minimize the duration of contact against their bodies. Moreover, fabrics used to manufacture garments of this type are often synthetic or synthetic blends that do not allow the skin to breathe, and this adds to the discomfort. At the other end of the spectrum are higher end garments made of state of the art 30 woven fabrics that are very comfortable for the individual wearing them. Such garments are favored by athletes, and include features designed to minimize the stress of exercise in areas of the body such as the lower extremities. It would be advantageous if an undergarment could be designed to include the shaping features of the more traditional shaping garments while including the novel 35 fabrics, comfort and support of high-end training clothing. It would be even more advantageous if such a garment were designed for everyday use and would solicit the -1- WO 2010/102378 PCT/CA2009/001898 muscles of the pelvic girdle to exercise, resulting in caloric burn. The present application seeks to meet these and other related needs. SUMMARY OF THE INVENTION It is an object of the present application to obviate or mitigate the disadvantages of 5 traditional shapers while including some of the more desirable elements of high-end training clothing. In a first aspect, the present application provides a novel undergarment and/or shaper with carefully positioned non-stretch (or isometric) bands, or the equivalent thereof, that are relatively more resistant (i.e., less stretchy or elastic) than the fabric that 10 is used to construct the remainder of the undergarment. These bands have a direct effect on muscles that would normally be activated during regular activity and cause them to be exercised to a further degree, but in a gentle manner. The effect, which in many cases is slightly perceptible, is felt while the wearer goes about his or her daily routine. Through the use of the non-stretch bands, the undergarment has the effect of 15 increasing external load. This results in an increase in muscle work and a concomitant increase in energy expenditure, or overall caloric loss. An objective for the underwear is to increase exercise of body muscles used in daily living. This is achieved by causing certain muscles to work against the more restrictive nature of the underwear, i.e., against carefully positioned resistance or "non 20 stretch" bands, as will be described more particularly below. Advantageously, and contrary to what is known in the art, the novel undergarment of the present application results in the burning of more calories for the same amount of work as wearing a conventional pair of underwear. The closest known prior art is not actually an undergarment but consists of high-end training garments used to enhance 25 athletic performance through energy saving compression bands along the targeted muscle groups. An example of this closest art is Wacoals CW-X series, designed to enhance training performance while decreasing energy expenditure. Scientifically, caloric burn is measured by oxygen consumption, through V0 2 max measurements. Comparable prior art, such as Wacoal, claim overall lower V0 2 max 30 consumptions for the wearer during exercise. Significantly, the undergarment of the present application results in the opposite effect: There is a higher 02 consumption under similar circumstances of use. Other aspects and features of the present application will become apparent to those of ordinary skill in the art upon review of the following description of specific 35 embodiments thereof, along with the accompanying figures. -2- WO 2010/102378 PCT/CA2009/001898 BRIEF DESCRIPTION OF THE FIGURES Embodiments of the undergarment of the present application will now be described, by way of example only, with reference to the attached Figures wherein: Figures 1 and 1 a show a commercial embodiment of the undergarment of the 5 present application; Figures 2 to 4 reveal the concept upon which the caloric burn aspect of the undergarment of the present application is based; Figure 5 is a diagrammatic posterior view of one embodiment of the undergarment of the present application; 10 Figure 6 is a posterior view of a prototype embodiment of the undergarment of the present application, as worn on a mannequin; Figure 7 is a close-up posterior view of the undergarment of Figure 6; Fig. 8 is an anterior view of the undergarment of the undergarment of Figure 6; Fig. 9 is an alternative anterior view of the undergarment of Figure 6; 15 Figures 10 and 11 are energy expansion graphs showing the efficiency of the novel undergarment of the application in inducing caloric burn; and Figures 12 to 15 show the "resistance effect" that is created by the carefully positioned non-stretch bands, or equivalent thereof, that are found in the undergarment of the present application. 20 DETAILED DESCRIPTION Definitions Unless specifically defined, all terms used herein have the meanings or definitions that would be ordinarily understood or used by those of skill in the art to which the present application pertains. 25 As used herein, the terms "undergarment", "underwear" and all other similar terms are used synonymously and interchangeably to describe a garment or clothing that is worn under outer clothing, usually close to the skin. For greater certainty, the terms are used to designate garments or clothing not only worn close to the skin, but on the lower part of the body (i.e., the buttocks, hips and thighs). 30 As used herein, the expression "non-stretch" used to describe the resistance bands (or equivalent thereof) that are an integral part of the undergarment, means that the fabric that constitute these bands (or equivalent thereof) are relatively more resistant (i.e., less stretchy or elastic) than the fabric that is used to construct the remainder of the undergarment. -3- WO 2010/102378 PCT/CA2009/001898 As used herein, the expression "caloric burn" means that there is an expansion of energy (i.e., calories) that is a benefit and advantage of the undergarment of the present application. Generally, the present application provides a novel undergarment. This 5 undergarment has the added feature of inducing caloric burn when it is worn (i.e., while the wearer is involved in his or her daily routine). An embodiment of this garment, which is shown as worn on a mannequin in Figures 5 to 9 and described more particularly below, induces caloric burn by offering resistance and modifying the motor control system responsible for gait. 10 The novel undergarment of the application has been carefully designed with a view to eliminating many of the inconveniences or harmful aspects of girdle-like support garments. Specifically, it has been noted that girdle-like support can lead to muscle flaccidity. When muscles are weak, the body loses the contribution of global muscle support, and this in turn can be a precursor to develop musculoskeletal dysfunction and 15 related health issues. The present undergarment is not a girdle but rather a supporting garment that engages select muscles in the trunk and hip regions of the wearer and that are activated through regular activity (more specifically, with movements involving hip flexion).. It is this increase in muscle activity that leads to caloric burn. Regular to moderate activities have 20 been found to be the most favorable to induce the desired result. The effects of the undergarment are enhanced when the wearer performs daily living activities or exercise, as explained further in the Examples below. The expansion of energy, or caloric burn, is possible due to the strategic positioning of bands of material having a density, or a series of densities, that differ(s) 25 from the overall density or thickness of the primary fabric or material that is used to make the undergarment. These bands create a "resistance" against which muscles in the lower extremities of the body will gently work or exercise, resulting in the expansion of energy. The basic principles of manufacturing behind the undergarment are based on knitting techniques, differing fiber contents and the choice of fabric (or fabrics) woven 30 together. The undergarment can be created using knitted or woven materials, or combinations of both, in keeping with practices known in the art. For knitted undergarments, the type of knitting machine along with the specific fiber content, such as polymer and elastomer mixtures as well as synthetic and natural fibers, play an important role in the efficacy of the final product. 35 Several types of stitch construction are used in the same garment in order to create varying textile tensions or densities resulting in both elastic and inelastic elements -4- WO 2010/102378 PCT/CA2009/001898 in different sections of the garment. Stitch density, elasticity and capacity to stretch vertically and horizontally contribute to either augment or diminish the resistance in the undergarment. For woven types of undergarment, the differing tensions are created by 5 assembling fabrics of differing fiber contents, mixtures of Lycra@, nylon and elastomeric treated fabrics. The resistance bands are sewn or heat-bonded in place in the garment to create the same effect as in a knitted version, namely, an elastic undergarment with carefully positioned non-stretch bands, or the equivalent thereof. The denier (number of grams of fiber per 9000 meters of thread) of the fibers differs according to the fabric 10 selected for the undergarment and has a direct impact on the characteristics of the final product. For both knitted and woven fabric constructions, the number of threads per inch along with the tension in grams per force, are determining factors in the strength of the resistance or the degree of elasticity in the undergarment. The gussets of both 15 undergarments are primarily cotton and Coolmax@. The final products are also treated with the finishing agents used to soften the fabrics, wick moisture, and a special agent to retain fiber memory so that the elasticity and resistance can be maintained over multiple washings. The concept is shown graphically in Figures 1 to 4. As shown more particularly in 20 Figures 1, Ia and 2, non-stretch bands or the equivalent thereof are placed so as to increase the resistance in the pelvic girdle and lower limbs. Looking more specifically at Figure 1, a prototypical embodiment of the undergarment of the application is shown. The undergarment is generally designated by the number 10 and includes a panty 2, a gusset 4, a waistband 6 and leg bands 8. 25 Resistance bands 20 are strategically positioned within the undergarment (see Figure 2) so as to provide resistance and muscle toning, and this in turn results in an increase in caloric burn. Figure la shows the undergarment of Figure 1 in its intended use, as worn by an individual. By increasing the work load to the pelvic girdle muscles during unipodal stance, 30 there is an increase in the work of the contralateral posterior muscle chain to stabilize the trunk in this unstable condition. For example, during walking, when right hip flexors contract to move the right lower limb forward, the left hamstring and gluteus maximus, as well as the right latissimus dorsi via the thoraco-lumbar fascia all increase their activities. As further shown in Figure 3, non-stretch bands are attached to the distal part of 35 the thigh. The conic effect of the thigh prevents the band from moving upwards. From this anchoring point, two non-stretch bands, or the equivalent thereof, are slanted backwards, -5- WO 2010/102378 PCT/CA2009/001898 one by the interior and the other from the outside of the thighs, up to the waistline. As illustrated in Figure 4, the two bands intersect at the ischium (A) in order to rely on a rigid point for better efficacy. Thereafter, the outer band will focus on the opposite iliac crest (B) while the internal band is attached to the external part of the ipsilateral iliac crest (C). 5 The exact positioning of the bands, or equivalents thereof, may be modified somewhat but are based on the above idea. Returning now to Figures 5 to 9, an embodiment of an undergarment in which the above-described concept has been reduced to practice is shown. As may seen more particularly in Figures 5 and 6, the sections of the undergarment that include the 10 equivalent of the bands described above are shown in darker-colored fabric and are made of a denser material. This material is relatively inelastic when compared with the remainder of the material comprising the undergarment in order to engage the underlying muscles into activity and induce caloric burn. Figures 7 and 8 show anterior views of the undergarment, including the thigh bands or strips that effectively anchor the posterior 15 bands in place to ensure maximum efficiency when in use. It will be understood that the principles behind the undergarment of the present application can be included within a limitless number of embodiments that can include an endless variety of aesthetic and other practical features. For example, the undergarment can be made from a number of different fabrics and materials. It can also be made in an 20 infinite number of colors and include elements that are more gender specific for individual appeal and comfort. In addition, the garment may be extended to cover a greater portion or even the entire length of the legs and feet, or the waist band section elongated along the torso to provide further support and enhance its ability to provide an overall slenderizing effect. 25 Without wishing to be bound by any theory, the caloric burn effect of the novel undergarment of the present application is believed to rely on the muscle chain theory. Specifically, bands having very little or no elasticity are strategically positioned within the undergarment, as described in greater detail below, to trigger the muscle chains and then affect moving and postural muscles. The result is that the person wearing the 30 undergarment expends energy by gently but effectively forcing the muscles to work against the resistance bands. Advantageously, as will be shown further below, the effects are noticeable even when the wearer engages in normal daily active. The caloric burn effect can be enhanced through moderate activity. Figures 10 and 11 are energy expansion graphs demonstrating the caloric burn 35 effect of the undergarment of the present application. Caloric burn evaluation methods were based on the measurement of heart rate (an indirect energy expenditure) as well as -6- WO 2010/102378 PCT/CA2009/001898 oxygen intake, V0 2 (a direct energy expenditure). In Figure 9, the results are shown for a cross section of individuals wearing regular underwear, a slimming type of underwear and the caloric burn undergarment of the present application. It may be seen from this graph that the caloric burn effect is optimal when the wearer engages in moderate activity. This 5 finding is confirmed by the results shown in Figure 10, which contrast the energy expenditure resulting from wearing a slimmer and the undergarment of the present application. EXAMPLE 1: Biomechanical Concept of Muscle Effort in Human Locomotion All muscular efforts lead to an elevation of the energetic metabolism that varies 10 with the intensity of the effort. The greater the effort, the greater the degree of solicitation to the muscle fiber engaged with the effort. This in turn leads to a greater need for energy, and therefore to an increase in energy consumption. The mechanical work accomplished by the muscles during locomotion can be divided in to 2 components: 15 1. Wext= the external work accomplished by the muscles in order to move the center of gravity of the body (CG) in relationship to its environment. 2. Wint= the internal work accomplished by the muscles to move the whole body part in relationship to the center of gravity (Cavagna et al 1963) The total mechanical work = Wtot=Wex+ Wint 20 With each step, the CG undergoes a translation or a linear displacement upwards and forwards under the effect of the Wext. This is accomplished by the muscles that modify the energy potential Epot, its upwards kinetic energy (Ekin) and its kinetic energy forward (Ekinf). Wext is the algebraic sum of Wf+W,, which is a fraction of the external work necessary for the displacement of the body forward and upwards, respectively. 25 During stance phase, the foot has a null speed relative to the ground while the CG continues its translation at its own speed. In turn, during the oscillation of the lower limb, the foot is brought back towards the front with a speed superior the one of the center of gravity. Therefore, with each step, the limbs are, turn by turn, in front of or behind the CG. Wint is therefore the work accomplished by the muscles to reconfigure the system 30 (Williams 1993). The proposed mechanical model for walking by Cavagna et al., 1963 is characterized by the variation in opposition in the phases of potential energy and the kinetic energy forward and upwards. The opposing mechanism of these phases permits the reciprocal transformation of these two forms of mechanical energy, one into the other, 35 just like a pendulum, leading to a most efficient use of energy while walking (Figures 12 to -7- WO 2010/102378 PCT/CA2009/001898 15). The neurology of the body is adapted to regulate the body to reproduce this efficient movement as much as possible. The reciprocal pendulum mechanism of (Epot+Eln.) and Ekinf characteristics of the walking motion has the effect of minimizing the mechanical work effected by the muscles 5 to move the center of gravity and, consequently, minimizing the energy costs. The percentage of energy recuperated by the pendulum mechanism is given by: R=(( Wf+Wv-Wext)/(Wf+Wv))X 100 In a perfect pendulum effect, R=100% and Wext =0. In this situation, the variations of potential energy and the kinetic energy are in a perfect opposing phase. All factors 10 perturbing one of these conditions will have the effect of disrupting the efficiency of the walking cycle. The pendulum mechanism constitutes the first physical objective interpretation of the existence of an optimal speed during walking. The speed at which walking is the closest to the conditions of a pendulum is ideal for optimal energy efficiency by the body. Above this speed, Wext increases, and therefore 15 directly increasing the energy expended in movement. Preliminary Efficacy Results of the Undergarment of the Present Application With its non-extensible band, the undergarment of the present application has the effect of increasing the Wext, which represents a direct increase of the muscular work involved in the same movement and therefore a direct increase of the energy expended. 20 When the energy spent increases, more calories are consumed to perform the same work. Work from Thys et al. 1996 demonstrated that the optimal speed for walking is between 4 and 5 km/hr (2.5 to 3 MPH). It is therefore at these speeds that the pendulum effect is optimal. To confirm the efficacy of the undergarment of the application, it was 25 tested at these walking speeds. The cumulative results show an average increased energy expansion of 20.7%. EXAMPLE 2: Typical Day for a 35-45 year old female living in the USA (Body weight 163 pounds and 64 inches) 30 Background about calories required in a "typical" day During rest (lying comfortably, essentially no activity) the body's tissues require about one-fourth of a liter of oxygen. The oxygen powers all bodily functions for the nervous system, digestion, brain and muscle activity, temperature regulation, and so on. In effect, the oxygen keeps the trillions of cells functioning while in the resting state. Oxygen use is 35 related to heat production in a very precise manner. Every 1 liter of oxygen "burned" releases 5 calories (kilocalories) of heat energy. Thus, oxygen use is really a measure of heat production. At rest, the body's tissues consume one-fourth of a liter, the equivalent -8- WO 2010/102378 PCT/CA2009/001898 of one-fourth of 5 kcal or 1.25 kcal for each minute at rest. There are 1440 minutes in a day, so if a person did nothing all day long (remained in the resting state), 1440 X 1.25 kcal = 1800 kcal would still be "burned." This value is the minimum energy (or calories) that the body requires at rest. This can be called the resting energy metabolism (the basal 5 metabolism differs slightly-a little less energy required-and is measured under strict laboratory conditions, usually in a medical setting). This resting energy value above is for a typical person of average body weight and height, and varies slightly for people who are bigger and taller and smaller and lighter, and all those between. To compute the total quantity of calories that a person 10 requires in a typical day requires knowing how many additional calories are required for all other activities above the resting level. This varies tremendously depending on what the person does during his or her non-sleeping hours. If the person sleeps for 8 hours, that leaves 16 hours for sitting, walking, recreation, etc. The value could go as high as 3500 to 4000 or more "extra" calories burned in a highly trained, competitive endurance 15 athlete who trains strenuously at a large percentage of his or her maximum capacity each day, to only 300-400 calories for a confirmed couch potato. The table below shows an example of physical activities for a 35-45 year old female living in the USA who weighs 163 pounds and is 64 inches tall. Calorie charts are available to compute the calories burned for each of the activities in the table based on a 20 body weight of 163 pounds. In the example, it is assumed that the total calories burned through physical activity equals 700 calories. This means that for this person on a typical day, she would "burn" or require a total of 1800 (resting metabolism) + 700 (the activities) = 2500 TOTAL kcal for the day. By wearing the undergarment of the present application during the day, she would burn an extra 35 to 105 kcal. The last row gives the equivalent 25 for the number of pounds of fat loss. Approximately 3500 kcal is equivalent to 1 pound of fat loss. The values in the table were calculated as number of calories X 365 days = total number of extra calories burned daily, divided by 3500 kcal. For example, if the undergarment has a 10% effect, this means 70 "extra" kcal daily X 365 days = 25,550 kcal, or the equivalent of 7.3 pounds of fat loss during the year that are attributable to 30 wearing the undergarment. 5 percent of 700 kcal 10 percent of 700 kcal 15 percent of 700 kcal 35 extra calories 70 extra calories 105 extra calories 12,775 kcal yearly 25,550 kcal yearly 38,325 kcal yearly 3.7 pounds fat loss 7.3 pounds fat loss 11 pounds fat loss -9- WO 2010/102378 PCT/CA2009/001898 EXAMPLE 3: Independent study conducted at the University of Virginia: Impact of a Lightweight Nylon Fiber Undergarment on the Energy Cost of Walking in Middle Aged Women PURPOSE: The energy deficit required to prevent weight gain in most adults 5 averages approximately 100 kcal daily. As a novel approach to closing this energy gap, we examined the effects of a nylon fiber undergarment designed to gently resist hip flexion during movement on the energy cost of walking. METHODS: Fifteen middle-age women (age= 39.4+/-6.6 yr; stature= 167.9+/-6.4 cm; body mass= 74.6+/-7.6kg; BMI= 26.4+/-1.6 kg/m 2 ) participated in 2x15-min treadmill 10 walking tests separated by 15-min of rest. Treadmill velocity remained constant for each test (3.0 mph) with grade increased 5% every 5-min (0%, 5%, 10%). In a randomized order, subjects completed one test wearing the undergarment (G) and a control test with their usual undergarment (C). Indirect calorimetry assessed energy expenditure (EE; kCal/min- 1 ) for each treadmill grade as the mean of the last 2-min of each 5-min segment. 15 RESULTS: No significant differences occurred in EE between G and C at 0% grade (G= 4.69 +/- 0.7 vs C= 4.70 +/- 0.8 kCal/min- 1 ; p=0.96). Walking EE tended to be higher with the G at 5% grade (G= 6.73 +/- 0.8 vs C= 6.58 +/- 0.9 kCal/min- 1 ; p=0.11); in contrast, EE was significantly elevated with the G at 10% grade (G= 9.41 +/- 1.1 vs C= 9.13 +/- 1.2 kCal/min- 1 ; p=0.04). Eleven subjects (73%) who responded to the garment 20 increased walking energy expenditure by 3 to 16%. CONCLUSIONS: The nylon undergarment effectively augmented the energy cost of walking particularly at higher treadmill grades. This may have direct utility to increase the caloric cost of other common physical activities of daily living such as walking uphill, hiking, or stair climbing. 25 In the preceding description, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the embodiments of the novel undergarment of the present application. However, it will be apparent to one skilled in the art that these specific details are not required in order to practice the invention. Moreover, while the application has been described primarily in relation to a specific 30 embodiment thereof, the concept behind it may be used in a variety of different types of undergarments, and even garments worn externally, including embodiments that cover the entire leg or torso, for example. The above-described embodiments of the undergarment of the application are therefore intended to be examples only. Variations, alterations and modifications can be 35 made to the particular embodiments described herein by those of skill in the art without departing from the scope of the invention, as it is defined by the claims appended hereto. -10-
