“…The physiological responses to CWT depend on a number of variables such as rest intervals between exercises [24], intensity [25, 26], gender [26–29], and the combination of endurance and resistance exercises in the same circuit [27]. We used submaximal intensity (70% of 15RM), short rest intervals between exercises (15 seconds), and 1:2 (concentric: eccentric) frequency in an attempt to reproduce an aerobic-type format.…”

ObjectivesThe present study describes the oxygen uptake and total energy expenditure (including both aerobic and anaerobic contribution) response during three different circuit weight training (CWT) protocols of equivalent duration composed of free weight exercises, machine exercises, and a combination of free weight exercises intercalating aerobic exercise.DesignControlled, randomized crossover designs.MethodsSubjects completed in a randomized order three circuit weight training protocols of the same duration (3 sets of 8 exercises, 45min 15s) and intensity (70% of 15 repetitions maximum). The circuit protocols were composed of free weight exercises, machine exercises, or a combination of free weight exercises with aerobic exercise. Oxygen consumption and lactate concentration were measured throughout the circuit to estimate aerobic and anaerobic energy expenditure respectively.ResultsEnergy expenditure is higher in the combined exercise protocol (29.9±3.6 ml/kg/min), compared with Freeweight (24.2±2.8ml/kg/min) and Machine (20.4±2.9ml/kg/min). The combined exercise protocol produced the highest total energy expenditure but the lowest lactate concentration and perceived exertion. The anaerobic contribution to total energy expenditure was higher in the machine and free weight protocols compared with the combined exercise protocol (6.2%, 4.6% and 2.3% respectively).ConclusionsIn the proposed protocols, the combined exercise protocol results in the highest oxygen consumption. Total energy expenditure is related to the type of exercise included in the circuit. Anaerobic contributions to total energy expenditure during circuit weight training may be modest, but lack of their estimation may underestimate total energy expenditure.Trial RegistrationClinicalTrials.gov NCT01116856

“…However, in most studies, ergometer exercises (Ee) traditionally are used to perform what is known as aerobic-type exercise (Sultana et al, 2012; Wang et al, 2012; Wright et al, 2012); and bars, free weights or machines are used to perform traditional anaerobic-type STe (Bloomer 2005; De Sousa et al, 2012; Mukaimoto and Ohno, 2012; Scott et al, 2011). A relevant aspect to be considered is how to match the load and intensity between STe and Ee, respectively.…”

“…In our view, pairing or matching % VO2max with % 1RM does not guarantee the same physiological intensity between both types of exercise (Bloomer 2005; Steele et al, 2012). To be predominantly aerobic for example, rhythmic and continuous exercises that work a large muscle group should be performed with an intensity at, but not above, the accumulation of 4 mmol/l blood lactate, and/or corresponding to the ventilatory threshold (Mukaimoto and Ohno, 2012); this is not at all ensured by using a percentage of 1RM. Thus, we hypothesised that the higher values of VO2 during, and lower after, Ee as compared to traditional STe, were due to the variables defining the intensity or load and not the type of devices used.…”

The aim of this study was to compare the values of oxygen uptake (VO2) during and after strength training exercises (STe) and ergometer exercises (Ee), matched for intensity and exercise time. Eight men (24 ± 2.33 years) performed upper and lower body cycling Ee at the individual’s ventilatory threshold (VE/VCO2). The STe session included half squats and the bench press which were performed with a load at the individual blood lactate concentration of 4 mmol/l. Both sessions lasted 30 minutes, alternating 50 seconds of effort with a 10 second transition time between upper and lower body work. The averaged overall VO2 between sessions was significantly higher for Ee (24.96 ± 3.6 ml·kg·min-1) compared to STe (21.66 ± 1.77 ml·kg·min-1) (p = 0.035), but this difference was only seen for the first 20 minutes of exercise. Absolute VO2 values between sessions did not reveal differences. There were more statistically greater values in Ee compared to STe, regarding VO2 of lower limbs (25.44 ± 3.84 ml·kg·min-1 versus 21.83 ± 2·24 ml·kg·min-1; p = 0.038) and upper limbs (24.49 ± 3.84 ml·kg·min-1 versus 21.54 ± 1.77 ml·kg·min-1; p = 0.047). There were further significant differences regarding the moment effect (p<0.0001) of both STe and Ee sessions. With respect to the moment × session effect, only VO2 5 minutes into recovery showed significant differences (p = 0.017). In conclusion, although significant increases in VO2 were seen following Ee compared to STe, it appears that the load/intensity, and not the material/equipment used for the execution of an exercise, are variables that best influence oxygen uptake.

“…To what extent EPOC is responsible for these mechanisms is currently unknown, but it is thought to be attributed to such (Schuenke et al, 2002). Regardless, EPOC and its duration, are identified to be in direct correlation to the length of the exercise bout and intensity (Drummond, Vehrs, Schaalje, & Parcell, 2005;Kaminsky, Padjen, & LaHam-Seager, 1990;LaForgia et al, 2006;Mukaimoto & Ohno, 2012;Schuenke et al, 2002;Thornton, Rossi, & McMillan, 2011;Tremblay et al, 1994).…”

Purpose:The purpose of this study was to determine if a creatine supplement prevents the decrease in performance while consuming a low carbohydrate (CHO) diet during high-intensity exercise. Compared to the placebo group where the low CHO diet was expected to result in reduced exercise tolerance, it was hypothesized that creatine supplementation would offset the adverse side effects of a low CHO diet, as demonstrated by a similar or improved exercise capacity. Methods: Twenty healthy subjects (8 males, 12 females; 27 ± 7 yrs, ±SD) were randomly assigned to a low CHO plus creatine monohydrate supplement (L-CHO+Cr), low CHO diet and placebo (L-CHO) group, or control (CON). Each subject performed 2 high intensity exercise tolerance tests (HIETT) to fatigue at 90% peak power output (PPO), separated by a 10 days where the subject followed a low CHO diet (<30% total consumption). Subjects completed a progressive exercise test to volitional fatigue to establish baseline fitness determined as peak O2 uptake (VO2peak) and to determine 90% of the peak work. The HEITT was on a 1:1 ratio of 30-seconds at 90% peak work rate followed by 30-seconds of no load active recovery. Heart rate was collected at baseline and every interval during iv both exercise sessions. Subjects consumed a loading dose of creatine monohydrate (20 g/day) or placebo (5g/day), while adhering to a low-CHO diet of <30% CHO total daily consumption. Subjects kept detailed food and exercise logs for the duration of the study. Results:The L-CHO+Cr group was of a similar fitness (36.1 ± 5.3 ml/kg/min) compared to the L-CHO group (36.9 ± 5.8 ml/kg/min) as determined by the progressive test to volitional fatigue. There was a statistically significant difference between the L-CHO+Cr group and the L-CHO HEITT performance pre-and post-dietary intervention (p=0.001).On average the L-CHO+Cr group demonstrated a 20% increase in the total number of bouts performed (pre/post), whereas the placebo group exhibited a 36% decrease. Both groups exhibited an average body fat loss of 1.0%, which was not statistically significant. Conclusion:The results of the present study demonstrated that a creatine loading protocol attenuates the fatigue associated with consuming a diet low in carbohydrate content, and indeed, leads to an improvement in high-intensity interval exercise performance. While the specific mechanism(s) underlying the improvement in performance was not identified in the present study, these findings are consistent with the results of studied demonstrating a significant relationship between the rate of phosphocreatine utilization following a dietary intervention and exercise performance. v
