 question, participants were asked to write down a number. The couples were instructed not to share or discuss their information with each other. In the present study, we presume that the perception of sexual activity is unique for each participant. Thus, the aim of these questions was to explore in detail how participants are making sense of their personal experiences. Measure of Energy Expenditure Free living energy expenditure during sexual activity and the endurance exercise session was measured using the portable mini SenseWear armband (Bodymedia, Pittsburgh, PA). The portable armband uses a 3-axis accelerometer, a heat flux sensor, a galvanic skin response sensor, a skin temperature sensor, and a near-body ambient temperature sensor to capture data. These data as well as body weight, height, handedness and smoking status (smoker or non-smoker) are used to calculate energy expenditure. The armband was placed on the upper left arm (on the triceps at the mid-humerus point) of each volunteer. The net output is a measure of energy expenditure (kcal) and intensity (METS) utilized by the participant across time. Data analysis for energy expenditure and intensity were available minute by minute (SenseWear professional software 7.0). This method of energy expenditure measurement has been validated by several studies and is known to be 92 % accurate compared to the gold standard method of doubly labeled water [17-24]. In addition, a test–retest reliability trial (n = 34) for energy expenditure performed in our laboratory showed an intra-class correlation coefficient of 0.97 [25]. It should be noted that mean energy expenditure and intensity were measured during the four different sessions of sexual activity. Couples were instructed to wear the armbands right before the start of the sexual activity and take it off at the end of their sexual encounter. Statistical Methods Results are presented as means ± SD. Normality was verified using the Kurtosis-test. To address our primary and secondary outcomes, paired t-tests were used to identify differences in energy expenditure and intensity between sexual activity and the 30 minute exercise session in both men and women. Moreover, a repeated measures ANOVA using the post-hoc assessment of LSD was used to detect differences in energy expenditure between all four sessions of sexual activity in both men and women. Furthermore, unpaired t-tests were used to detect differences in age, body mass index, energy expenditure and intensity between men and women. To address our tertiary outcome, 1) paired t-
question, participants were asked to write down a numeral. The couple were instructed not to share or discuss their data with each other. In the present study, we presume that the percept of sexual activity is alone for each participant. Thus, the bearing of these questions was to explore in contingent how participants are making sense of their personal experiences. Measure of Energy Expenditure Free living energy outgo during sexual activity and the endurance use session was measured practice the portable mini SenseWear armband (Bodymedia, Pittsburgh, PA). The portable armband uses a 3 - bloc accelerometer, a heat flux density sensor, a galvanic skin reception sensor, a skin temperature sensor, and a near - body ambient temperature sensor to capture data. These data as well as body weight, height, handedness and smoking status (smoker or non - smoker) are use to calculate energy consumption. The armband was placed on the upper left arm (on the triceps at the mid - humerus point) of each tennessean. The net end product is a measure of energy consumption (kcal) and intensity (METS) utilized by the participant across time. Data analysis for department of energy expenditure and intensity were available minute by minute (SenseWear professional software 7.0). This method of energy expenditure measurement has been validate by several studies and is known to be 92% accurate compared to the gold standard method acting of doubly labeled water [ 17 - 24 ]. In addition, a test – retest reliability trial (n = 34) for energy expenditure performed in our testing ground showed an intra - class correlation coefficient coefficient of 0.97 [ 25 ]. It should be noted that mean energy expenditure and intensity were measure during the four different session of sexual activeness. Couples were instructed to wear the armbands right before the starting signal of the sexual activity and take it off at the end of their sexual encounter. Statistical Methods Results are presented as means ± SD. Normality was verify using the Kurtosis - test. To cover our primary and secondary outcomes, paired t - tests were used to name differences in energy expenditure and intensity between sexual activity and the 30 minute exercise school term in both serviceman and women. Moreover, a recur measures ANOVA using the post - hoc appraisal of LSD was used to detect differences in energy outgo between all four session of sexual activity in both men and womanhood.
