Acute effect of stretching one leg on regional arterial stiffness in young men

Background. Performing resistance exercise could lead to an increase in arterial stiffness.Objective. We investigate the acute effect on arterial stiffness by performing Valsalva manoeuvre during resistance exercise.Materials and Methods. Eighteen healthy young men were assigned to perform bicep curls by using two breathing techniques (exhalation and Valsalva manoeuvre during muscle contraction) on two separate study days. Carotid pulsed wave velocity (cPWV) was measured as an indicator to reflect the body central arterial stiffness using a high-resolution ultrasound system, and its value was monitored repeatedly at three predefined time intervals: before resistance exercise, immediately after exercise, and 15 minutes after exercise.Results. At the 0th minute after resistance exercise was performed using the Valsalva manoeuvre during exertion, a significant increase in cPWV (4.91 m/s ± 0.52) compared with the baseline value (4.67 m/s ± 0.32,P=0.008) was observed, and then it nearly returned to its baseline value at the 15th minute after exercise (4.66 m/s ± 0.44,P=0.010). These findings persisted after adjusting for age, body mass index, and systolic blood pressure.Conclusion. Our result suggests short duration of resistance exercise may provoke a transient increase in central arterial stiffness in healthy young men.

AbstractTo examine the acute influence of pedaling cadence on arterial stiffness in young men, 15 healthy men (21.8±0.4 years) underwent 3 trials in self-control crossover design: non-cycling control (CON), cycling at 60 (RPM60) and 90 rounds per min (RPM90). Cycling lasted 30 min at intensity of 35% heart rate reserve. Arterial stiffness in cardio-ankle vascular index (CAVI) was measured at baseline (BL), immediately after (0 min) and 40 min after cycling. There were no significant CAVI changes over time in CON. CAVI in RPM60 decreased immediately after exercise and returned to baseline afterwards (6.1±0.2, 5.6±0.2 and 6.0±0.2 at BL, 0 and 40 min, respectively). RPM90 elicited significant CAVI reduction from 6.2±0.2 at BL to 5.5±0.2 at 0 min, and reverted to 5.7±0.1 at 40 min, maintaining significant difference to its baseline. There was no significant CAVI difference between RPM60 and CON, whereas CAVI in RPM90 was significantly lower than that in CON at 0 min (5.5±0.2 vs 6.1±0.2, P<0.01) and 40 min (5.7±0.1 vs 6.3±0.1, P<0.05). Despite equivalent exercise volume, arterial stiffness improvement induced by cycling was influenced by pedaling cadence. Higher cadence resulted in superior effect on arterial stiffness.

Endurance Strength

The present study verified the effect of a concurrent training (CT) session in different orders, Strength + Endurance (SE) and Endurance + Strength (ES), on the glycemic control. The crossover study included 20 young men, 21.80 ± 2.90 years, IMC ≥ 23 kg/m2, 24.83 ± 3.68% of fat, who performed both CT sessions separated by 72 h. Capillary glycemia was measured at pre, immediately post the end of each exercise session, and during the recovery period at 30, 60, and 90 minutes. The comparisons were performed using Two-way ANOVA (order and time), paired test-t for the area under the curve, as well as Cohen’s d effect size. There was effect of exercise order (F = 5.973; p = 0.03), effect of time (F = 18.345; p = 0.001) and interaction between order and time (F = 2.835; p = 0.03). The area under the curve presented a significant reduction (p = 0.03, effect size = 0.51, moderate). The area under the curve was smaller in SE, as well as glucose concentrations at end and post 30 min of exercise, suggesting better efficiency in glycemic control compared to ES.
