Where To Buy Berlei Bras In Usa
A variety of wearable technology devices report heart rate. Heart rate sensing smart bras are manufactured for females who participate in activity, however accuracy has not been determined. The purpose was to determine the validity of heart rate measures in three commercially available sports bras during walking and running. Twenty-four healthy females completed bouts of treadmill exercise. The Adidas Smart sports bra, Berlei sports bra, and Sensoria Fitness biometric sports bra were tested. Participant perception of each garment was obtained immediately after the participant divested the sports bra. The Adidas Smart sports bra was valid only during rest (Intraclass correlation Coefficient [ICC] = 0.79, mean absolute percentage error [MAPE] = 4.5%, Limits of Agreement [LoA]=-8 to 8). The Berlei sports bra was valid across all conditions (ICC = 0.99, MAPE = 0.66%, LoA = -19 to 19), and the Sensoria biometric bra was valid during rest and walking (ICC = 0.96, MAPE = 1.9%, LoA = -15 to 12). Perception of the smart sports bras was higher for the Adidas Smart sports bra and Sensoria Fitness sports bra, and lower for the Berlei sports bra. Sports bra manufacturers designing wearable technology garments must consider the ability of returning accurate biometric data while providing necessary function and comfort to females engaging in physical activity.

You can find three main styles of sports bras: those that primarily employ compression, those that primarily employ encapsulation, and those that use a combination of the two. We considered all those styles when looking for bras to test.
Encapsulation bras separate the breasts into cups using a piece of fabric called a gore (PDF) and provide support through seaming, molding, or underwire instead of flattening; they look like typical bras. Most encapsulation bras also use a familiar sizing system, including both cup measurements (A, B, C, D, E, F, and so on) and band measurements (32, 34, 40, 44, and so on) as opposed to basic S/M/L/XL sizing. Typically, encapsulation bras offer more, better-fitting options than compression bras. Separating the breasts can also prevent them from rubbing together and chafing during exercise.
Once they have the correct sizes, our testers try on or contemplate three to nine bras and then choose two to five of them to try in earnest. They give detailed feedback on our criteria. And they wear each of the finalist bras for at least two runs and one cross-training session or an equivalent number of high-impact activities. In several cases, they continue wearing the bras for months to years after their initial testing and continue to provide long-term testing feedback.

Second-by-second validation of heart rate obtained from three smart bras compared to a criterion measure over various conditions (rest, warm up, run, walk, and over the entire period). Validation tests include mean absolute percentage error (MAPE), Bland-Altman limits of agreement with (associated 95% confidence intervals), and Intraclass correlations (ICC) with associated 95% confidence intervals (CI) and p-values.
Second-by-second reliability of heart rate obtained from three smart bras over various conditions (rest, warm up, run, walk, and over the entire period). Absolute reliability is represented as the coefficient of variation (CV), and test-retest reliability is presented as Intraclass correlations (ICC) with associated 95% confidence intervals (CI) and p-values.
Subjective ratings (presented in arbitrary units, AU) of the Adidas Smart sports bra, the Berlei sports bra, and the Sensoria Fitness biometric sports bra. Participants provided perception on a scale of zero to ten, with zero being the lowest possible score, and ten being the greatest possible score. Data are presented as mean standard error, and differences between smart bras are noted by the p-value on the figure. 041b061a72
