A similar reduction of the postprandial glycemic response was observed with different exercise types (Studies 2 and 3). Thirty and 45 min of brisk walking provided a similar reduction of the postprandial glucose response (Study 5). When performing activity breaks, 10 and 20 min of cumulative exercise were sufficient to attenuate postprandial glycemia in the first-hour post-meal (Study 6).

Our findings provide insight into how to choose timing, type, duration, and modality for postprandial exercise prescription in healthy individuals.

The ergogenic effects of respiratory alkalosis induced by prior voluntary hyperventilation (VH) are controversial. This study examined the effects of prior VH on derived parameters from the 3-min all-out cycling test (3MT).

Eleven men ([Combining Dot Above]V˙O2max = 46 ± 8 mL⋅kg-1⋅min-1) performed a 3MT preceded by 15-min of rest (CONT) or voluntary hyperventilation (V˙E = 38 ± 5 L⋅min-1) with PETCO2 reduced to 21 ± 1 mmHg (HYP). End-test power (EP; synonymous with critical power) was calculated as the mean power output over the last 30-s of the 3MT, and the work done above EP (WEP; synonymous with W') was calculated as the power-time integral above EP.

At the start of the 3MT, capillary blood PCO2 and [H+] were lower in HYP (25.2 ± 3.0 mmHg, 27.1 ± 2.6 nmol⋅L-1) than CONT (43.2 ± 2.0 mmHg, 40.0 ± 1.5 nmol⋅L-1) (P < 0.001). At the end of the 3MT, blood PCO2 was still lower in HYP (35.7 ± 5.4 mmHg) than CONT (40.6 ± 5.0 mmHg) (P < 0.001). WEP was 10% higher in HYP (19.4 ± 7.0 kJ) than CONT (17.6 ± 6.4 kJ) (P = 0.006), whereas EP was 5% lower in HYP (246 ± 69 W) than CONT (260 ± 74 W) (P = 0.007). The ΔWEP (J·kg-1) between CONT and HYP correlated positively with the PCO2 immediately before the 3MT in HYP (r = 0.77, P = 0.006).

These findings suggest that acid-base changes elicited by prior voluntary hyperventilation increase WEP but decrease EP during the all-out 3MT.

to investigate the effect of cannabidiol (CBD) oil on perceived muscle soreness, inflammation, and strength performance after eccentric exercise (ECC) of the elbow flexors.

Thirteen untrained men (mean ±SD age 21.85±2.73a) performed 6 sets of 10 maximal ECC isokinetic muscle actions of the elbow flexors as part of a double-blind cross-over design. Non-invasive (perceived soreness, arm circumference, hanging joint angle (JA), and peak torque (PT)) measures were taken PRE-, POST-, 24-h, 48-h, and 72-h post ECC. All subjects completed both the supplement (CBD150 mg POST, 24-h,48-h) and placebo (PLC POST, 24-h,48-h) condition separated by 2 weeks. Four separate two-way repeated measures ANOVAs (condition [CBD vs. https://www.selleckchem.com/products/ziritaxestat.html PLC] x time [PREvs.POSTvs.24hvs.48hvs.72h]) were used to analyze perceived soreness, arm circumference, JA, and PT. One-way repeated measures ANOVAs were used to decompose significant interactions and main effects.

There was no condition x time interaction or main effect of condition (p>0.05) for perceived soreness, arm circumference, JA, or PT. There were main effects for time for perceived soreness (p=0.000,ηp2=0.71) and JA (p=0.006, ηp2=0.35).

The current dose of 150 mg CBD oil at POST, 24-h, and 48-h had no effect on non-invasive markers of muscle-damage in the upper extremity. At the current dose and schedule, CBD oil may not be beneficial for untrained men as a recovery aid after exercise-induced muscle damage.

To identify the relationships between lower limb muscle characteristics and the mechanical variables derived from the vertical (jumping) and horizontal (sprinting) force-velocity-power (FVP) profiles.

Nineteen sub-elite male rugby league players performed a series of squat jumps and linear 30 m sprints to derive the vertical and horizontal FVP profiles, respectively. The theoretical maximal force (F0), velocity (V0) and power (Pmax) were derived from both the vertical (i.e., vF0, vV0 and vPmax) and horizontal (i.e., hF0, hV0 and hPmax) FVP profiles. Vastus lateralis (VL), biceps femoris (BF) long head and gastrocnemius medialis (GM) and lateralis muscle fascicle length, pennation angle and thickness were measured using B-mode ultrasonography. Magnetic resonance (MR) imaging was used to calculate volumes of major lower limb muscles, while proton MR spectroscopy was used to quantify the carnosine content of the GM to estimate muscle fiber typology.

Variation in vPmax was best explained by GM muscle fiber typology (i.e., greater estimated proportion of type II fibers) and VL volume (adjusted r2=0.440; P=0.006), while adductor and vastus medialis volume and GM muscle fiber typology explained the most variation in hPmax (adjusted r2=0.634, P=0.032). Rectus femoris and VL volume explained variation in vF0 (r2=0.430; P=0.008), while adductor and vastus medialis volume explained variation in hF0 (r2=0.432; P=0.007). Variation in vV0 and hV0 were best explained by GM muscle fiber typology (adjusted r2=0.580, P<0.001) and GM muscle fiber typology and BF short head volume (adjusted r2 = 0.590, P<0.001), respectively.

Muscle fiber typology and muscle volume are strong determinants of maximal muscle power in jumping and sprinting by influencing the velocity- and force-orientated mechanical variables.
