Objective: To compare the acute and chronic effects of low-volume high-intensity interval training (HIIT) to moderate-intensity continuous training (MICT) on glycemic control, body composition and continuous glucose monitoring (CGM) in older women with type 2 diabetes (T2D). Methods: Thirty older women (68 ± 5 years) with T2D were randomized in two groups—HIIT (75 min/week) or MICT (150 min/week). Glucose homeostasis (A1c, glucose, insulin, HOMA-IR2) and body composition (iDXA) were measured before and after the 12-week exercise intervention. During the first and last week of training (24-h before and 48-h after exercise), the following CGM-derived data were measured: 24-h and peak glucose levels, glucose variability and time spent in hypoglycemia as well as severe and mild hyperglycemia. Results: While lean body mass increased (p = 0.035), total and trunk fat mass decreased (p ≤ 0.007), without any difference between groups (p ≥ 0.81). Fasting glucose levels (p = 0.001) and A1c (p = 0.014) significantly improved in MICT only, with a significant difference between groups for fasting glucose (p = 0.02). Neither HIIT nor MICT impacted CGM-derived data at week 1 (p ≥ 0.25). However, 24-h and peak glucose levels, as well as time spent in mild hyperglycemia, decreased in HIIT at week 12 (p ≤ 0.03). Conclusion: These results suggest that 12 weeks of low-volume HIIT is enough to provide similar benefit to MICT for body composition and improve the acute effect of exercise when measured with CGM.

High-intensity interval training (HIIT) has similar or better effects than moderate-intensity continuous training (MICT) in increasing peak oxygen consumption (VO2max), however, it has not been studied when HIIT is applied in a circuit (HIICT). The aim of this study was to compare the effects of a HIICT versus MICT on VO2max estimated (VO2max-ES), heart rate (HR) and blood pressure (BP) of middle-aged and older women. A quasi-experimental randomized controlled trial was used. Fifty-four women (67.8 ± 6.2 years) were randomized to either HIICT (n = 18), MICT (n = 18) or non-exercise control group (CG; n = 18) for 18 weeks. Participants in HIICT and MICT trained two days/week (one hour/session). Forty-one participants were assessed (HIICT; n = 17, MICT; n = 12, CG; n = 12). Five adverse events were reported. Cardiorespiratory fitness, HR and BP were measured. The tests were performed before and after the exercise intervention programs. VO2max-ES showed significant training x group interaction, in which HIICT and MICT were statistically superior to CG. Moreover, HIICT and MICT were statistically better than CG in the diastolic blood pressure after exercise (DBPex) interaction. For the systolic blood pressure after exercise (SBPex), HIICT was statistically better than CG. In conclusion, both HIICT and MICT generated adaptations in VO2max-ES and DBPex. Furthermore, only HIICT generated positive effects on the SBPex. Therefore, both training methods can be considered for use in exercise programs involving middle-aged and older women.

Β2 Adrenergic Receptor

The β2 adrenergic receptor (β2-AR) plays an important role in vascular smooth muscle. However, the interaction between Arg16Gly and Gln27Glu β2-AR polymorphisms, and exercise training has not yet been established. This study evaluated the influence of these β2-AR polymorphisms on body composition, aerobic capacity, blood pressure, lipid profile, nitric oxide, and redox status at baseline and in response to an exercise program in women aged 50–79 years. Genotype and haplotypes were analyzed in association with the previously mentioned variables before and after the multicomponent training (12 weeks, 2 sessions/week, 90 min/session, and exercise intensity between 13 and 15 on the Borg scale). Individuals who carry β2-AR Arg16Arg/Gln27Gln genotypes presented more improvements in blood pressure, body composition, aerobic capacity, and redox status in response to a multicomponent training program compared with individuals who do not carry this haplotype. In some years, the genetic profile may be used to predict which exercise program can induce more health benefits for each person.

AbstractThis study investigated the acute post-exercise effect of high-velocity resistance exercise on ambulatory blood pressure in hypertensive older women. Fourteen volunteers (67.9±5.1 years) performed a high-velocity resistance exercise session (8 exercises using Thera-Band, 3 sets of 6 repetitions as fast as possible in the concentric phase with moderate intensity) and a control session, separated by a 7–10-day period. Ambulatory blood pressure was monitored following 12-h post-sessions and compared between conditions at 1 to 4-h, 5 to 8-h, and 9 to 12-h. Average 24-h ambulatory blood pressure, awake, asleep periods, and blood pressure load were also analyzed. There was a condition by time interaction for systolic ambulatory blood pressure over 12-h post-sessions (P=0.043). It was observed a lower systolic ambulatory blood pressure in the first 4-h period following the high-velocity resistance exercise session compared to the control session (−6.7 mmHg, 95% CI  − 11.6 to −1.8 mmHg; P=0.011). No changes were observed for diastolic ambulatory blood pressure over 12-h post-sessions as well as for the other variables analyzed (P>0.05). In summary, a single high-velocity resistance exercise session elicits a post-exercise antihypertensive effect and may be considered as a strategy to acutely improve blood pressure control in hypertensive older women.

Aim: The purpose of the present study was to investigate the association of sociodemographic (skin color, socioeconomic level, educational level, occupational and marital status) and health (high blood pressure, self-reported health problems, use of medicines and health perception), with the functional fitness in older women. Methods: This cross-sectional study investigates sociodemographic and health variables assessed by questionnaires and the association with functional fitness measured with the "Senior Fitness Test". Statistical analysis used the Kruskal -Wallis test to check for differences between age groups, chi-square tests and logistic regression analyses to investigate associations between each component of functional fitness and independent variables. Results: The final sample consisted of 1,806 older women, mean age 68.93 years (SD 6.6). Sociodemographic (skin color, socioeconomic class and educational level) and health variables (High blood pressure, self-reported health problems and health perception) were associated with different components of functional fitness and the overall score of functional capacity.  Conclusion: Among all the independent variables, educational level and health perception were those most correlated to functional fitness.

Abstract Introduction: Physical activity is one of the basic elements that affect functional performance and body composition. The age may result in adverse changes in these parameters. The study aimed to compare the functional fitness and body composition in physically active women over 60 years old in different age groups and determine the relationship between those two components. Material and methods: The study participants attended gymnastic classes at the University of Third Age of Warsaw University of Technology. A total of 39 women were examined in three age categories - 60-64 years (13 women), 65-69 years (13 women), 70-74 years (13 women). The study used the Senior Fitness Test (SFT) to assess functional fitness. Body composition was tested using a device Tanita BC 420. Results: Statistical analysis showed no statistically significant (p≤0.05) differences in functional fitness and body composition between women of different age groups. A statistically significant negative correlation was found for Back Scratch test with BMI and percentage of body fat and a positive with muscle mass. Additionally, 8-ft up-and-go test positively correlated with BMI and percentage of body fat and negatively with muscle mass. Conclusions: Regular physical activity allows to maintain the level of functional fitness in older women. Element requiring additional commitment are flexibility exercises. The study confirmed the relationship between body composition and functional fitness of older women.
