Abstract This study compared the effects of using continuous and interval aerobic exercise during concurrent training on cardiorespiratory adaptations in women. Thirty-two participants were randomly assigned into one of the following groups: continuous running and resistance training (C-RUN, n = 10), interval running and resistance training (I-RUN, n = 11), or control group that performed resistance training only (RT, n = 11). Each group trained twice a week during 11 weeks. Oxygen uptake corresponding to the first ventilatory threshold (VO2VT1), second ventilatory threshold (VO2VT2) and maximal effort (VO2max) was measured in a maximal incremental test performed before and after training. Significant increases in VO2VT1, VO2VT2 and VO2max were observed in all training groups. VO2VT2 and VO2max presented time-group interactions, indicating that the magnitude of the increase in these variables was dependent on the training group (VO2VT2: C-Run = 6.6%, I-Run = 15.7%, RT = 1.7%; VO2max: C-Run = 7.2%, I-Run = 14.3%, RT = 2.7%). The effect size observed for post-training values comparing C-RUN and RT groups was d = 0.566 for VO2VT2 and d = 0.442 for VO2max. On the other hand, values of d = 0.949 for VO2VT2 and d = 1.189 for VO2max were verified between I-RUN and RT groups. In conclusion, the use of continuous and interval aerobic exercise during concurrent training improved different cardiorespiratory parameters in women, but in a greater magnitude when interval aerobic exercise was performed simultaneously to resistance training.

Although weight training can enhance muscular strength, power, and body composition, outdated beliefs about muscular adaptations have limited its use in dancers. The purpose of this study was to investigate the effect of an 8-week progressive overload resistance-training (RT) program on muscular strength, power and body composition in collegiate female dancers. Sixteen subjects were randomised into a dance-only control group (CON) or an RT + dance training group (EXP). EXP met 3×/week for RT. Body fat (%BF), lean body mass (LBM), girth measurements, vertical jump (VJ), muscular strength (1-repetition max (RM) squat (SQT) and 1-RM bench press (BP)), maximal oxygen consumption (V̇O2max, and ventilatory threshold (VT)) were assessed pre- and post-study. Baseline performance characteristics across all subjects were: %BF=28.2±5.7%, VJ=33.4±5.4 cm, SQT=57.5±12.1 kg, BP=30.1±7.6 kg, (V̇O2max)=40.6±3.4 ml/kg/min, and VT=71.2±3.4%VO2max. Strength improvements were significantly greater for EXP than CON (P<0.05). No significant differences were found between groups for %BF, LBM, girth measurements, VJheight, (V̇O2max), or VT (P>0.05). However, a trend was observed for VJpower favouring EXP (P=0.07). EXP significantly improved strength, while no significant changes were observed in body composition. However, EXP improved their power-to-weight ratio, which may be a positive performance adaptation. RT for dancers can improve strength and power, allowing enhanced muscular loading and fatigue-resistance, which may optimise performance and decrease injury risk.

Abstract Loss of physical performance is a universal problem of cancer patients undergoing chemotherapy. We postulated that this impairment can be partially prevented by aerobic exercise. In a randomized study, 33 cancer patients receiving high-dose chemotherapy followed by autologous peripheral blood stem cell transplantation (training group, T) performed an exercise program consisting of biking on an ergometer in the supine position after an interval-training pattern for 30 minutes daily during hospitalization. Patients in the control group (C, n = 37) did not train. Maximal physical performance was assessed with a treadmill test by admission and discharge. Physical performance of the two groups was not different on admission. The decrement in performance during hospitalization was 27% greater in the control group than in the training group (P = .05); this resulted in a significantly higher maximal physical performance at discharge in the trained patients (P = .04). Duration of neutropenia (P = .01) and thrombopenia (P = .06), severity of diarrhea (P = .04), severity of pain (P = .01), and duration of hospitalization (P = .03) were reduced in the training group. We conclude that aerobic exercise can be safely carried out immediately after high-dose chemotherapy and can partially prevent loss of physical performance. Based on the potential significance of the observed outcomes, further studies are warranted to confirm our results.

Abstract Background Physiological aging can now be considered as a multi-factorial process that is associated with anatomical and signaling changes associated with endocrine function. The purpose of this study was to investigate the comparison of performing 12 weeks’ resistance training before, after and/or in between aerobic exercise on the hormonal status of aged women. Materials and methods Forty healthy aged women (age: 67.35 ± 1.40 years) were randomly divided into three training groups and a control group: resistance followed by endurance training (ER, n = 12), endurance training followed by resistance training (RE, n = 12, interval resistance-endurance (RE) training (INT, n = 12) and a control (Con, n = 12) groups. The training program was done over 12 weeks, 3 times per week. Endurance training was performed on a cycle ergometer (intensity: 60–90% maximum heart rate) and resistance training involved selected resistance exercises (intensity: 40–75 one-repetition maximum, 8–18 repeats). All participants were evaluated before and after the training period. Results and conclusion The data showed that performing resistance training before, after and/or in between aerobic exercise did not influence the adaptive response of insulin like growth factor-1 (IGF-1) (p = 0.07), growth hormone (p = 0.35), cortisol (p = 0.20), insulin (p = 0.72), epinephrine (p = 0.83) and norepinephrine (p = 0.86) levels throughout the study. However, when comparing pre and post, no significant differences were shown following combined training within the SE, ES and INT groups for all variables (p < 0.05), except of IGF-1 within ES (p = 0.04) and SE (p = 0.02), and testosterone within ES (p = 0.007). In conclusion, combined training with RE order may be more effective than other orders for increasing anabolic status in aged women.

This study assessed the effects of inactivity on GLUT-4 content of human skeletal muscle and evaluated resistance training as a countermeasure to inactivity-related changes in GLUT-4 content in skeletal muscle. Nine young men participated in the study. For 19 days, four control subjects remained in a −6° head-down tilt at all times throughout bed rest, except for showering every other day. Five training group subjects also remained at bed rest, except during resistance training once in the morning. The resistance training consisted of 30 isometric maximal voluntary contractions for 3 s each; leg-press exercise was used to recruit the extensor muscles of the ankle, knee, and hip. Pauses (3 s) were allowed between bouts of maximal contraction. Muscle biopsy samples were obtained from the lateral aspect of vastus lateralis (VL) muscle before and after the bed rest. GLUT-4 content in VL muscle of the control group was significantly decreased after bed rest (473 ± 48 vs. 398 ± 66 counts ⋅ min−1 ⋅ μg membrane protein−1, before and after bed rest, respectively), whereas GLUT-4 significantly increased in the training group with bed rest (510 ± 158 vs. 663 ± 189 counts ⋅ min−1 ⋅ μg membrane protein−1, before and after bed rest, respectively). The present study demonstrated that GLUT-4 in VL muscle decreased by ∼16% after 19 days of bed rest, and isometric resistance training during bed rest induced a 30% increase above the value of GLUT-4 before bed rest.

The novel myokine irisin has been reported as a therapeutic target for metabolic disease. The objective of this study is to reveal the effects of aerobic training (AT) and resistance training (RT) on circulating irisin levels and their associations with change of body composition in overweight/obese adults. Twenty eight overweight/obese adults (BMI>23 kg/m2) were included in this study and compared before and after 8 weeks of exercise program (60 min/day, 5 times in a week). The subjects, in both aerobic and resistance training, showed significant improvement in anthropometric parameters and exercise capacities including maximal oxygen uptake and muscle strength. Interestingly, the circulating irisin was significantly increased in resistance training group (p=0.002) but not in aerobic training (p=0.426) compared to control group. In addition, we found the positive correlation between change of the circulating irisin and muscle mass (r=0.432, p=0.022) and the negative correlation between change of the circulating irisin and fat mass (r=−0.407, p=0.031). In the present pilot study, we found that circulating irisin level was increased by 8 weeks of resistance training in overweight/obese adults, suggesting that resistance training could be the efficient exercise type in overweight/obese considering positive change of body composition concomitant with increase of irisin levels.

Background: Interval training is a method with high acceptance in prescription to increase health and can be an essential intervener in improving cardiovascular function. Objective: This study aimed to verify the effects of eight weeks of interval training with different intensities on hemodynamic and autonomic function, which were assessed through resting heart rate, blood pressure, dual product, and heart rate variability. Methods: The sample consisted of 24 older men (age: 68.8 ± 6.8 years, body mass: 74.4 ± 18.1 kg, height: 1.70 ± 0.8 m; BMI: 25.1 ± 2, 2) who were physically active. Participants were randomized into 3 experimental groups: training group A (TGA, n = 8), training group B (TGB, n = 8) and control group (CG, n = 8). For trained groups, interventions were developed twice a week for eight weeks, with an interval of 48 hours between the sessions. The evaluations were carried out at the pre (baseline) and after the eighth week of intervention. The control group did not perform any intervention. The variables were analyzed for 10 minutes with subjects at rest in the sitting position before and after the intervention. Statistics with a significance level of p <0.05 were applied. Results: After the intervention, no statistically significant results were found in the variables assessed (p> 0.05). Conclusion: The intervention was not sufficient to promote statistical differences in hemodynamic and autonomic variables.

Background: Osteoarthritis is one of the articular disorders. This disorder causes pain, impaired physical function and thus affecting the quality of life of individuals by limiting individual independence. Objectives: The purpose of the current study was to investigate the effect of eight weeks of hand-selected strength training and cinnamon-honey supplementation on strength and range of motion of wrist joint in elderly women with osteoarthritis. Methods: In this study, 48 women with hand-osteoarthritis were selected and randomly divided into four groups (strength training, cinnamon-honey supplementation, combinatory and control). The training group underwent the hand-selected strength training; the second group used honey and cinnamon powder supplement for 8 weeks and once a day. The third group also received hand-selected training and cinnamon and honey supplements simultaneously. The fourth group also participated in this study as a control group without any training or supplementation. Patients’ wrist strength and range of motion were measured before and after applying the independent variables and were compared. Results: The results showed that by applying the strength training and cinnamon-honey supplementary as well as the combination of training and supplementary have had a positive effect on strength and range of motion of wrist in fact, 8 weeks of resistance training and using cinnamon-honey supplements in women with hand osteoarthritis have led to a increases. Conclusions: Therefore, it is recommended to use resistance training with cinnamon and honey supplements to accelerate the recovery of the disease.

The effect of endurance interval training (IT) on hematocrit (Ht), hemoglobin (Hb), and estimated plasma-volume variation (PVV) in response to maximal exercise was studied in 15 male subjects (21.1 ± 1.1 y; control group n = 6, and training group, n = 9). The training group participated in interval training 3 times a week for 7 wk. A maximal graded test (GXT) was performed to determine maximal aerobic power (MAP) and maximal aerobic speed (MAS) both before and after the training program. To determine Ht, Hb concentration, and lactate concentrations, blood was collected at rest, at the end of GXT, and after 10 and 30 min of recovery. MAP and MAS increased significantly (P < .05) after training only in training group. Hematocrit determined at rest was significantly lower in the training group than in the control group after the training period (P < .05). IT induced a significant increase of estimated PVV at rest for training group (P < .05), whereas there were no changes for control group. Hence, significant relationships were observed after training between PVV determined at the end of the maximal test and MAS (r = .60, P < .05) and MAP (r = .76, P < .05) only for training group. In conclusion, 7 wk of IT led to a significant increase in plasma volume that possibly contributed to the observed increase of aerobic fitness (MAP and MAS).

Background: The aim of this study was to evaluate the effects of high frequency exercise for patients before and after an elective percutaneous coronary intervention (PCI), with special reference to maximal aerobic capacity, muscle function, health related quality of life (HRQoL), waist–hip ratio (WHR) and restenosis. Methods: A randomised, controlled study was performed in Sweden between 2004 and 2006 in thirty-seven patients (five women) with stable coronary artery disease (CAD), age 63.6 ± 6.9 years, randomised to either high frequency exercise or control group. The patients in the training group performed three endurance resistance exercises and trained on a cycle ergometer 30 min, 5 times a week for 8 months at 70% of VO2max. Results: Patients in the training group significantly improved their maximal aerobic capacity (15 (9–46) vs. 8 (0–18)% p ≤ 0.05), shoulder flexion ( p ≤ 0.01), shoulder abduction ( p ≤ 0.01) and heel-lift ( p ≤ 0.05) compared to the control group. There were no significant differences between the groups in HRQoL, WHR and restenosis. Conclusion: High frequency exercise in patients treated with PCI seems to improve maximal aerobic capacity and muscle function, which may reduce the risks of further progression of atherosclerosis. However, further larger studies are needed to fully investigate the effects of exercise in patients with PCI.
