Purpose:To compare differences between two different rest interval lengths between sets on the volume completed, muscle damage and muscle soreness during a resistance exercise bout.Methods:Twenty-eight healthy sedentary men (18 ± 1 y old) volunteered to participate in this study and were divided into the 1 min (1RI; n = 14) or 3 min (3RI; n = 14) rest interval length between sets. They were submitted to maximal voluntary isometric contraction strength (MVC) and then performed a resistance exercise protocol constituted for three sets of biceps curl at 40% of MVC with 1 min (1RI group) or 3 min (3RI group) interval length between sets. Each bout was performed to voluntary fatigue and the workout volume completed was calculated. Subjects provided blood samples before each bout, and at 24, and 48 h following exercise to evaluate serum CK activity. Muscle soreness was analyzed through visual analog scale, which was presented to subjects before frst bout, immediately after exercise protocol and at 24, and 48 h following exercise.Results:The results demonstrated that the subjects with longer rest intervals provide greater workout volume as expected, but there were no differences in serum CK activity and muscle soreness between groups.Conclusion:Training with highvolume, low-intensity resistance training, exercising with short rest intervals does not appear to present any additional challenge to recovery in untrained subjects.

Purpose:We examined the effects of creatine supplementation on the response to repeated bouts of resistance exercise.Methods:Young men (24.1 ± 5.2 yr) were divided into Creatine (CM, n = 9) and Placebo (PL, n = 9) groups. On day (D) 1 and D15, subjects performed four sets of bicep curls at 75% 1-RM to concentric failure. On D8-D13, subjects consumed either 20g/d creatine monohydrate or placebo. Muscle soreness and elbow joint range of motion (ROM) were assessed on D1-D5 and D15-D19. Serum creatine kinase activity (CK) was assessed on D1, D3, D5, D15, D17, and D19.Results:The first exercise bout produced increases in muscle soreness and CK, and decreases in ROM in both groups (p < .001). The second bout produced lesser rises in serum CK, muscle soreness, and a lesser decrease in ROM (bout effect, p < .01 for all), with greater attenuation of these damage markers in CM than PL. CK levels on D17 were lower (+110% over D15 for CM vs. +343% for PL), muscle soreness from D15–19 was lower (–75% for CM vs. –56% for PL compared with first bout), and elbow ROM was decreased in PL, but not CM on D16 (p < .05 for all).Conclusions:Creatine supplementation provides an additive effect on blunting the rise of muscle damage markers following a repeated bout of resistance exercise. The mechanism by which creatine augments the repeated bout effect is unknown but is likely due to a combination of creatine’s multifaceted functions.

Purpose: To determine how the rest interval (RI) lengths of 30 and 90 s between sets of biceps curl exercise affect the total volume of work performed and serum CK activity, and to verify the relationship between inter-individual variability of CK activity and total volume performed when the resistance exercise bout is conducted with 30 or 90 s Methods: Twenty-seven healthy sedentary men (18–20 years old) volunteered to participate in this study and were divided into two groups: 30RI (n = 16) or 90RI (n = 11), based on the RI length of 30 or 90 s between the sets of a resistance exercise protocol. The one repetition maximum (1RM) assessment of the elbow flexion was carried out and then a resistance exercise protocol which constituted five sets of biceps curl at 85% of 1RM with 30-s (30RI group) or 90-s (90RI group) RI length between sets was performed. Each bout was performed to voluntary fatigue and the number of repetitions and workout volume completed were calculated. Subjects provided blood samples prior to resistance exercise, and at 48 and 96h following exercise to evaluate serum CK activity. The inter-individual serum CK activity along the 96h after exercise was analyzed. Results: The results demonstrated that the longer RIs provided greater workout volume as expected, but there were no differences in serum CK activity between the groups. Additionally, it was possible to identify two high responder subjects, one from each RI group, who showed a great inter-individual serum CK activity variability. Conclusion: Exercising with short RIs does not appear to present any additional muscle microtrauma to untrained subjects. Further studies are necessary to evaluate if the inter-individual variability of the serum CK activity is influenced by the inter-set RI length.

The purpose of this study was to investigate the effects of nocebo administration on perceived soreness and exercise performance following unaccustomed resistance exercise. Untrained males were randomly assigned to one of two treatments: (1) control or (2) negative-belief. For the negative-belief group, participants were given a capsule before exercise containing 400 mg of an inert substance (gluten-free cornstarch) and were told the supplement would increase muscle soreness. The control group received no treatment. An algometer and pain scale was used to obtain soreness, and a goniometer was used to measure elbow range of motion (ROM). Participants completed an eccentric bicep curl pyramid with their non-dominant arm. Rate of perceived exertion (RPE) and repetitions were recorded. Then, 48 h after the initial exercise bout, participants repeated all procedures. Perceived soreness, ROM, average RPE, and total repetitions performed were analyzed. Perceived soreness was significantly higher in both control and negative-belief groups 48 h after exercise (p < 0.001; η2 = 0.23). ROM was significantly lower 48 h post in the negative-belief group (p = 0.004; d = 1.83) while no differences existed for controls (p = 0.999; d = 0.16). Average RPE was unaffected between groups (p = 0.282; η2 = 0.07). Total repetitions were significantly lower 48 h post in the negative-belief group (p < 0.001; d = 2.51) while no differences existed for the controls (p = 0.999; d = 0.08). Findings suggest that 48 h after unaccustomed resistance exercise, negative expectation does not worsen soreness but hinders ROM and exercise performance.

The authors sought to determine whether consuming collagen peptides (CP) enhances musculoskeletal recovery of connective tissues following a damaging exercise bout. Resistance-trained males consumed 15 g/day of CP (n = 7) or placebo (n = 8), and after 7 days, maximal voluntary isometric contraction (MVIC), countermovement jump height, soreness, and collagen turnover were examined. Five sets of 20 drop jumps were performed and outcome measures were collected 24, 48, and 120 hr postexercise. Countermovement jump height was maintained in the CP group at 24 hr (PRE = 39.9 ± 8.8 cm vs. 24 hr = 37.9 ± 8.9 cm, p = .102), whereas the CP group experienced a significant decline at 24 hr (PRE = 40.4 ± 7.9 cm vs. 24 hr = 35.5 ± 6.4 cm, p = .001; d = 0.32). In both groups, muscle soreness was significantly higher than PRE at 24 hr (p = .001) and 48 hr (p = .018) but not at 120 hr (p > .05). MVIC in both legs showed a significant time effect (left: p = .007; right: p = .010) over the 5-day postexercise period. Neither collagen biomarker changed significantly at any time point. CP supplementation attenuated performance decline 24 hr following muscle damage. Acute consumption of CP may provide a performance benefit the day following a bout of damaging exercise in resistance-trained males.

Objectives: Plyometrics has been used in sports training and many aspects of this modality are poorly understood. This study measures the magnitude of variations of serum creatine kinase (CK) activity and perceived muscle soreness after one session of Countermovement Jump (CMJ) session and compares 1 and 3 minutes rest intervals between each sets.Methods: A group of 30 young male was dividing in two groups and performed ten sets of ten CMJ with 1 or 3 minutes rest interval between sets. Before and after session (24, 48, and 72-h) they informed the muscle soreness perception and blood samples were collected for dosage of serum CK activity. Two (time) x Two (treatment) ANOVA was used to test differences in serum CK activity and muscle soreness. The alpha level was set at 0.05.Results: Serum CK activity measured 48 h after session augments ~2 and ~1.5 times in 1 min and 3 min rest interval respectively. No significant difference between groups that rests 1 or 3 minutes between sets was found. Muscle soreness rises 24 h after session without significant differences between groups.Conclusions: The findings show that the CMJ increases perceived muscle soreness and increases the serum CK activity, and the intervals of rest do not modulate these variables.
