Bioimpedance analysis for identifying new indicators of exercise-induced muscle damage

A noninvasive, immediate, and convenient method for assessing muscle tissue status during exercise-induced muscle damage (EIMD) has not been established. This study was designed to assess and determine parameters suitable for measuring EIMD after eccentric exercise, using multi-frequency bioimpedance analysis (BIA). Thirty-five young male participants performed dumbbell exercises with their left arm, and their BIA parameters were measured at various time points up to 168 h post exercise using a multi-frequency BIA device. At all-time points, intra and extracellular water content was greater in the left arm than in the right arm, whereas the impedance, reactance, resistance, and phase angle were lower in the left arm than in the right arm. Established EIMD indices, such as maximal isometric voluntary contraction, were measured and used in correlational analyses. Only reactance was correlated with biomarkers, indicating muscle damage (r = − 0.56 to − 0.49). Furthermore, reactance was found to correlate well with indirect indicators of EIMD, suggesting that it may be a suitable marker for evaluating EIMD. However, the relationship with the limited evaluation indices employed in this study is constrained. Future studies should investigate the correlation between reactance and direct damage indicators, such as structural damage, observed in biopsies.

The Effect of Aerobic Exercises on Pain in Patients with Diabetic Peripheral Neuropathy

Background: Evidence has suggested that exercises have always been part of diabetes controlling programs in past and recent years. But recently new improvements have been noticed regarding use of Aerobic exercises in controlling variation in symptoms of diabetes type 2 especially neuropathic pain. It has been proved that Aerobic exercises are much useful in controlling neuropathic symptoms than simple exercises. Objective: This study was to determine the impacts of aerobic exercises on pain in diabetic neuropathic patients. Methodology: A randomized controlled trial was done on 80 patients who fulfilled inclusion criteria of diabetic neuropathy having 40 to 70 years of age with no serious systemic illness and sensitivity. Coin toss method was used to randomize the patients in two groups in the Physical therapy department of District Head Quarter Hospital Layyah, Pakistan. Baseline measurements and demographic data were taken before starting exercise plans. Patients were divided into two groups (group A) treatment group and (group B) control group. Treatment plan consisted on 10 weeks program. Group A was given Aerobic exercises plan like cycling, treadmill walking and Group B was given Strengthening exercises like pulley exercises, dumbbell exercises for a period of 30-minute session thrice a week initially which was later on increased to Four days a week. Data was analyzed through SPSS version 20. Paired t test were used to analyze the data. Results: The Physical Exam score within group showed before treatment 5.53± .91 and after treatment was 1.07±.59 (<0.001*) and it showed significant improvement with the intervention of aerobic groups. Mean difference of pre-test post-test score in strengthening group was 2.19±.40 and in aerobic group was 4.76±2.66 (P=0.010) showed there was significant difference between mean score of both groups. Mean score of pain in aerobic group in measurement was 79.1± 8.9 and after treatment was 39.2± 8.4 (<0.001*) showed significant effect with intervention of this group Conclusion: Aerobic exercises improve the intensity of pain in diabetic neuropathy patients while control group have no improvement of pain. While both experimental and control group showed some improvement regarding muscle tone and strength by exercises but intensity of pain only improved by Aerobic Exercises.

Oxygen Consumption (VO2) and Surface Electromyography (sEMG) during Moderate-Strength Training Exercises.

Oxygen consumption (VO2) during strength training can be predicted through surface electromyography (sEMG) of local muscles. This research aimed to determine relations between VO2 and sEMG of upper and lower body muscles to predict VO2 from sEMG during moderate-intensity strength training exercises. Of the 12 participants recruited, 11 were divided into two groups: untrained (n = 5; with no training experience) and trained (n = 6; with 2 months of training experience). On different days, each individual completed six training sessions. Each participant performed training sessions consisting of three types of dumbbell exercises: shoulder press, deadlift, and squat, while wearing a mask for indirect calorimetric measurements of VO2 using the Cortex Metalyzer 3B. sEMG measurements of the bilateral middle deltoid, lumbar erector spinae, quadriceps (rectus femoris), and hamstring (biceps femoris) muscles were recorded. The VO2 was predicted from sEMG root mean square (RMS) values of the investigated muscles during the exercise period using generalized estimating equation (GEE) modeling. The predicted models for the three types of exercises for the untrained vs. trained groups were shoulder press [QIC = 102, * p = 0.000 vs. QIC = 82, * p = 0.000], deadlift [QIC = 172, * p = 0.000 vs. QIC = 320, * p = 0.026], and squat [QIC = 76, * p = 0.000 vs. QIC = 348, * p = 0.001], respectively. It was observed that untrained vs. trained groups predicted GEE models [quasi-likelihood under an independence model criterion (QIC) = 368, p = 0.330 vs. QIC = 837, p = 0.058], respectively. The study obtained significant VO2 prediction models during shoulder press, deadlift, and squat exercises using the right and left middle deltoid, right and left lumbar erector spinae, left rectus femoris, and right and left biceps femoris sEMG RMS for the untrained and trained groups during moderate-intensity strength training exercises.

VALSALVA MACULOPATHY FOLLOWING STRENUOUS ACTIVITY: A CASE REPORT

Valsava maculopathy is one of many causes of premacular hemorrhage. This case report highlights the interest of multimodal imaging in the diagnosis of retinal emergencies which can engage the visual prognosis, especially in a young patient as in our case of Valsalva Maculopathy.A 32 years old male arrived at the ophthalmology emergency for a sudden painless loss of central vision in his left eye after doing some heavy dumbbell exercises without any context of traumatism. After the eye examination, he was been diagnosed with Valsalva maculopathy. The bleeding spontaneously resorbed. Follow-up after 12 weeks was uneventful.

Modeling of Metabolic Equivalents (METs) during Moderate Resistance Training Exercises

Energy expenditure through metabolic equivalent (MET) prediction during resistance exercises in humans can be modeled by using cardiorespiratory parameters. In this study, we aimed to predict MET during six moderate-intensity resistance training sessions consisting of three different exercises. Eleven participants were recruited into two groups; an untrained (n = 5; with no resistance training experience) and a trained group (n = 6; with 2 months resistance training experience). Each participant completed six training sessions separated with a rest interval of 1–2 days. While wearing a mask for indirect calorimetric measurements using Cortex Metalyzer 3B, each participant performed training sessions consisting of three types of dumbbell exercises: shoulder press, deadlift, and squat. The metabolic equivalents (METs), respiratory exchange ratio (RER), heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), blood lactate (BL), and Borg rate of perceived exertion (RPE) were measured. The MET was predicted using generalized estimating equations (GEE) for repeated measure data collected during exercise and rest periods. It was observed that during exercise period, RER, HR, SBP, and BL for the training group (QIC = 187, 95% CI = −0.012~0.915, p = 0.000*~0.033*) while RER, HR, SBP, DBP, and RPE (QIC = 48, 95% CI = −0.024~0.422, p = 0.000*~0.002*) during resting period for untrained group significantly predicted MET for moderate-intensity interval resistance training. It is concluded that the cardiorespiratory variables are significantly related to MET. During exercise, RER and HR significantly predicted MET for both groups along with additional parameters of SBP and BL for the training group. While during the resting period, RER, HR, SBP, DBP, and RPE related significantly for untrained and BL for training group respectively.

Energy Expenditure during Acute Weight Training Exercises in Healthy Participants: A Preliminary Study

Energy expenditure during weight training exercises produces great fitness and health benefits for humans, but few studies have investigated energy expenditure directly during weight training. Therefore, in this study, we aimed to determine energy costs during three training sessions consisting of three different exercises. Ten participants were randomly allocated into two groups: an untrained (n = 5, with no weight training experience) and a trained group (n = 5, with some weight training experience). Each participant completed three training sessions on separate days. While wearing a mask for indirect calorimetric measurements, each participant participated in training sessions conducted with three dumbbell exercises: the bent-over row, deadlift, and lunge. Metabolic equivalents (METs), energy expenditure (EE), respiratory exchange ratio (RER), heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and rate of perceived exertion (RPE) were measured. The total energy cost was calculated from the oxygen consumption (VO2) during each exercise. Our results showed that the METs of a single training session were 3.3 for the untrained group and 3.4 for the trained group, while the sum of the EE was 683–688 and 779–840 kcal, respectively. The physiological parameters, such as heart rate (p = 0.001 *) for the lunge and rate of perceived exertion (p = 0.005 *) for the bent-over row, changed significantly in both groups. It was concluded that the exercise protocol of this study involved a moderate intensity of 2.4–3.9 METs. The energy cost of each training exercise was between 179 and 291 kcal.

The effect of muscle fatigue on wrist joint position sense in healthy adults

Study designPretest and posttest experimental study. IntroductionThe effect of muscle fatigue on wrist joint position sense (JPS) has yet to be determined. Purpose of the StudyThe primary aim was to determine whether muscle fatigue affects wrist JPS in healthy adults. The secondary aims were to compare the effect of muscle fatigue on younger and older adults JPS and determine the association between JPS rate of change and total muscle fatigue (TMF) rates postexercise. MethodsForty male and female healthy adults were assigned into younger (18-40 years) and older (41-65 years) groups. Preexercise and postexercise testing consisted of active wrist JPS, handgrip, and wrist extensor strength assessments. Muscle fatigue was induced via a calibrated gripper and wrist extension dumbbell exercises. Dependent variables were the JPS rate of change (ie, preexercise and postexercise), TMF rate (ie, grip and wrist extension average strength decline), and Borg Rating of Perceived Exertion scale scores. ResultsPostexercise wrist JPS test scores were significantly higher than preexercise. Exercises induced statistically significant TMF rates and Borg Rating of Perceived Exertion scores among all participants. No statistically significant age-group differences on JPS rate of change, and TMF rate was found. A statistically significant mild correlation (r = 0.425) existed between JPS rate of change and TMF rates. DiscussionPostexercise fatigue significantly impairs wrist JPS in both younger and older adults. On average, an 18% muscle strength decline led to 215% wrist JPS deficit. ConclusionsSignificant wrist proprioception deficits persist for ≤5 min following exertional exercises, regardless of age level.

Acute effect of moderate-intensity concentric and eccentric exercise on cardiac effort, perceived exertion and interleukin-6 level in physically inactive males.

Muscle-derived interleukin-6 (IL-6) not only enhances glucose and fat metabolism but also has an anti-inflammatory effect that can prevent the development of cardiovascular disease (CVD) and metabolic syndrome. Dynamic resistance exercise comprises a muscle shortening and a lengthening phase known as concentric and eccentric contraction respectively. We compared an acute bout of concentric exercise (CE) with eccentric exercise (EE) for the serum IL-6 concentration, myocardial oxygen consumption (MVO2) and rating of perceived exertion (RPE). The present non-randomized crossover study involved 24 physically inactive but apparently healthy males, aged 18-25 years with body mass index of 18.5-23 kg/m2. Each participant performed an acute bout of moderate intensity CE followed by an EE bout after two weeks of rest. Exercise bout lasted for about 45 minutes that involved brisk walking on a treadmill at ±21% gradient for approximately 30 minutes, followed by the dumbbell exercises for biceps, triceps, quadriceps and hamstring muscles. MVO2 and IL-6 were estimated by the rate pressure product (RPP) and ELISA (enzyme-linked immunosorbent assay) kit respectively. Participants told their RPE after the workout. Wilcoxon or paired-t test were applied appropriately to compare the means. P<0.05 was considered significant. RPP, RPE, and serum IL-6 levels were significantly lower after EE (164.4±16.3, 12, and 1.1±0.5, respectively) than CE (191.2±22.9, 13, and 1.2±0.6, respectively). A significant, strong and positive correlation of RPE was obtained with post-exercise heart-rate and RPP. Regular EE might be beneficial for individuals having a low tolerance to exertion or at risk of developing CVD.

Development of a Web Exercise Video for Patients With Shoulder Problems.

The purpose of this study was to develop a Web video designed to promote regular shoulder joint exercise on a continuous basis among patients with shoulder joint disease. This is a methodological research. A shoulder joint exercise video was developed through the five stages of the ADDIE model: analysis, design, development, implementation, and evaluation. The video demonstrates exercises that stretch and strengthen the joints and muscles of the shoulders. Stretching exercises include the pendulum, forward elevation, outer rotation, crossover arm stretch, inner rotation, and the sleeper; strengthening exercises include dumbbell exercises, a chair exercise, wall push-ups, and rowing. This Web exercise video can be used as an educational resource for preventing shoulder joint diseases by middle-aged and elderly people and those seeking to restore shoulder joint function damaged by shoulder joint diseases.

Objective Assessment of Strength Training Exercises using a Wrist-Worn Accelerometer.

The 2008 Physical Activity Guidelines for Americans recommend that all adults perform muscle-strengthening exercises to work all of the major muscle groups of the body on at least 2 d·wk, in addition to aerobic activity. Studies using objective methods of monitoring physical activity have focused primarily on the assessment of aerobic activity. To date, a method for assessing resistance training (RT) exercises has not been developed using a wrist-worn activity monitor. The purpose of this study was to examine the use of a wrist-worn triaxial accelerometer-based activity monitor for classifying upper- and lower-body dumbbell RT exercises. Sixty participants performed 10 repetitions each of 12 different upper- and lower-body dynamic dumbbell exercises. Algorithms for classifying the exercises were developed using two different methods: support vector machine and cosine similarity. Confusion matrices were developed for each method, and intermethod reliabilities were assessed using Cohen's kappa. A repeated-measures ANOVA was used to compare the predicted repetitions, identified from the largest acceleration peaks, with the actual repetitions. The results indicated that support vector machine and cosine similarity accurately classified the 12 different RT exercises 78% and 85% of the time, respectively. Both methods struggled to correctly differentiate bench press versus shoulder press and squat versus walking lunges. Repetition estimates were not significantly different for 8 of the 12 exercises. For the four exercises that were significantly different, the differences amount to less than 10%. This study demonstrated that RT exercises can be accurately classified using a single activity monitor worn on the wrist.

Objective Assessment Of Resistance Training Exercises Using A Wrist-worn Tri-axial Accelerometer

The 2008 Physical Activity Guidelines for Americans recommend that all adults perform muscle-strengthening exercises to work all of the major muscle groups of the body on at least two days per week, in addition to aerobic activity. Studies using objective methods of monitoring physical activity have focused primarily on the assessment of aerobic activity. To date, a method to objectively classify resistance training exercises has not been developed using a wrist-worn activity monitor. PURPOSE: The purpose of this study was to examine the use of a wrist-worn, tri-axial accelerometer-based activity monitor (ActiGraph GT3X+) for classifying upper- and lower-body dumbbell resistance training exercises. METHODS: Sixty participants performed 12 different dynamic dumbbell exercises. The exercises included: bench press, shoulder press, biceps curls, upright rows, lateral raises, triceps extensions, triceps kickbacks, bent-over row (standing), bent-over row (kneeling), squats, walking lunges, and calf raises. Algorithms for classifying the exercises were developed using two different METHODS: support vector machine (SVM) and cosine similarity (CS). Confusion matrices were developed for each method and inter-method reliability was assessed using Cohen’s kappa. RESULTS: The results indicated that SVM and CS accurately classified the 12 different resistance training exercises 78% and 85% of the time, respectively. Both methods struggled to correctly differentiate bench press vs shoulder press and squat vs walking lunges. If those exercises were excluded, the accuracy of SVM and CS increased to 85% and 93%, respectively. CONCLUSION: This study demonstrated that individual resistance training exercises can be classified using a single activity monitor worn on the wrist. Future studies using larger sample sizes and additional data channels may be able to improve on the precision of the classification of resistance training exercises.

Shoulder- and Back-Muscle Activation During Shoulder Abduction and Flexion Using a Bodyblade Pro Versus Dumbbells

The Bodyblade Pro is used for shoulder rehabilitation after injury. Resistance is provided by blade Oscillations-faster oscillations or higher speeds correspond to greater resistance. However, research supporting the Bodyblade Pro's use is scarce, particularly in comparison with dumbbell training. To compare muscle activity, using electromyography (EMG), in the back and shoulder regions during shoulder exercises with the Bodyblade Pro vs dumbbells. Randomized crossover study. San Diego State University biomechanics laboratory. 11 healthy male subjects age 19-32 y. Subjects performed shoulder-flexion and -abduction exercises using a Bodyblade Pro and dumbbells (5, 8, and 10 lb) while EMG recorded activity of the deltoid, pectoralis major, infraspinatus, serratus anterior, and erector spinae. Average peak muscle activity (% maximum voluntary isometric contraction) was separately measured for shoulder abduction and flexion in the range of 85° to 95°. Differences among exercise devices were separately analyzed for the flexed and abducted positions using 1-way repeated-measures ANOVA. The Bodyblade Pro produced greater muscle activity than all the dumbbell trials. Differences were significant for all muscles measured (all P < .01) except for the erector spinae during shoulder flexion with a 10-lb dumbbell. EMG activity for the Bodyblade Pro exceeded 50% of the MVIC during both shoulder flexion and abduction. For the dumbbell conditions, only the 10-lb trials approached this effect. Using a Bodyblade during shoulder exercises results in greater shoulder- and back-muscle recruitment than dumbbells. The Bodyblade Pro can activate multiple muscles in a single exercise and thereby minimize the need for multiple dumbbell exercises. The Bodyblade Pro is an effective device for shoulder- and back-muscle activation that warrants further use by clinicians interested in its use for rehabilitation.

Comparison of the Effects of an Exercise Program in Non-obese and Obese Women

The purpose of this study was to compare the effects of an exercise program on physical fitness, obesity indices, and blood lipids in cases of non-obese and obese women. Data was collected from May, 2006 to November, 2006 in a public health center. All Subjects(37 women) participated in an exercise program that consisted of Latin dance, muscular strength training, and dumbbell exercises. Thirty-seven women were divided into two groups(16 non-obese women and 21 obese women) by %body fat. After 8 weeks, the effects of treatment were compared between pre-test and post-test in each group. Physical fitness(abdominal muscle strength, muscle endurance, flexibility, agility, balance) was significantly different between the pre-test and post-test in the non-obese and obese group. Obesity indices(body weight, BMI) was significantly different in obese women after the 8-week exercise program. There was no decrease of blood lipids in either group. These findings indicate that an exercise program could be an effective nursing intervention to increase physical fitness in non-obese and obese women and to decrease obesity indices(body weight, BMI) in obese women.
