Individuals with Down syndrome (DS) tend to prematurely reach the skeletal maturation period. In addition, young people with this condition have poor physical fitness and few opportunities to practice physical activity when compared to those without disabilities. The aim of this study was to investigate the skeletal maturation of young people with Down syndrome and its influence on the behavior of physical fitness related to health, after aerobic and resistance training programs. Forty people with DS, with an average age of 15.4 (± 2.6) years, were divided into three groups for a 12 weeks intervention program, AT - aerobic training group (3 times/week; 50 minutes/session), RT - resistance training group (twice/week ; 50 minutes/session) and CG - control group, 9 participants. Determination of skeletal age (EA) was performed using the Greulich-Pyle method. Anthropometric variables, muscle strength and peak VO2 were measured pre and post intervention. It was found that skeletal maturation influenced the effects of training, only being significant for body weight and strength in the upright row variables. In addition, the muscle strength of upper and lower limbs increased significantly after 12 weeks of aerobic or resistance training. Then, we can conclude that the effects of physical training on physical fitness of young people with Down syndrome appear to improve as the bone age increases.

DOI: http://dx.doi.org/10.5007/1980-0037.2017v19n4p385 The aim of this study was to investigate the effects of 12 weeks of aerobic and resistance training on the maximal and submaximal cardiorespiratory fitness of young people with Down Syndrome (DS). Forty-one individuals of both sexes with Down syndrome (age, 15.51±2.70 y) were divided into three groups: CG (control group) with 10 participants; ATG group (aerobic training group) with 16 participants; and RTG (resistance training group) with 15 participants. The training program lasted 12 weeks, with frequency of 3 days a week for ATG and two RTG, and duration of 50 minutes per session. Aerobic training consisted of exercise on a treadmill/bike at intensity between 50 and 70% of reserve heart rate, while resistance training was composed of nine exercises performed on three sets of 12 maximum repetitions for each exercise. Aerobic and resistance training were not able to increase peak oxygen uptake. However, there was an increase in the maximum ventilation and a decrease of submaximal heart rate only for groups who participated in the training program. Moreover, the aerobic group increased work capacity after training. Training programs led to an improvement in cardiac efficiency during submaximal activities and increased maximum ventilation, which demonstrates a cardiorespiratory improvement.

Objective: To determine the efficacy of a three-month resistance training programme on the mobility, muscle strength and lean body mass of patients with pancreatic cancer-induced cachexia. Design: Randomized controlled trial. Setting: Elsahel Teaching Hospital, outpatient clinic of the Faculty of Physical Therapy, Cairo, Egypt. Participants: Patients with pancreatic cancer-induced cachexia. Interventions: Participants were randomized to the resistance training group ( n = 20) and control group ( n = 20). Main measures: Outcomes including mobility, muscle strength and lean body mass were measured at baseline, three months after surgical resection and 12 weeks after intervention. Results: The mean (SD) age was 51.9 (5.03) years and body mass index was 21.1 (1.13) kg/m²; 65% of patients were male. Compared to the control group, the resistance training group showed significant improvement in mobility: 400-m walk performance (270.3–256.9 seconds vs 266.4–264.2 seconds, respectively) and chair rise (13.82–12.53 seconds vs 13.77–13.46 seconds, respectively). Similarly, muscle strength was also significantly improved in the resistance training group than in the control group; we observed increase in peak torque of knee extensors ( P = 0.004), elbow flexors ( P = 0.001) and elbow extensors, improvement in lean mass of the upper limb (6.28–6.46 kg vs 6.31–6.23 kg, respectively) and lower limb (16.31–16.58 kg vs 16.4–16.31 kg, respectively). Conclusion: A three-month resistance training improved the mobility of patients with pancreatic cancer-induced cachexia. Muscle strength and lean body mass also improved.

A detraining period after resistance training causes a significant decrease in trained-induced muscular adaptations. However, it is unclear how long muscle strength and hypertrophy gains last after different detraining periods. Thus, the present systematic review with meta-analysis aimed to evaluate the chronic effects of detraining on muscle strength and hypertrophy induced by resistance training. Searches were conducted on PubMed, Scopus, EBSCO, CINAHL, CENTRAL, and Web of Science. The difference in means and pooled standard deviations of outcomes were converted into Hedges’ g effect sizes (g). Twenty randomized and non-randomized trials (high and moderate risks of bias, respectively, and fair quality) were included for qualitative analysis of muscle strength and hypertrophy, while only two studies were included in the meta-analysis for maximum muscle strength. The resistance training group presented a significant increase in one-repetition maximum (1RM) chest press (g: 4.43 [3.65; 5.22], p < 0.001) and 1RM leg press strength (g: 4.47 [2.12; 6.82], p < 0.001) after training. The strength gains observed in the resistance training group were also maintained after 16–24 weeks of detraining (g: 1.99 [0.62; 3.36], p = 0.004; and g: 3.16 [0.82; 5.50], p = 0.008; respectively), when compared to the non-exercise control group. However, 1RM chest press and leg press strength level was similar between groups after 32 (g: 1.81 [−0.59; 4.21], p = 0.139; and g: 2.34 [−0.48; 5.16], p = 0.104; respectively) and 48 weeks of detraining (g: 1.01 [−0.76; 2.79], p = 0.263; and g: 1.16 [−1.09; 3.42], p = 0.311; respectively). There was not enough data to conduct a meta-analysis on muscular hypertrophy. In conclusion, the present systematic review and meta-analysis demonstrated that, when taking random error into account, there is no sufficient high-quality evidence to make any unbiased claim about how long changes in muscle strength induced by RT last after a DT period. Moreover, the effect of different DT periods on muscle hypertrophy induced by RT remains unknown since there was not enough data to conduct a meta-analysis with this variable.

This study aimed to investigate the effects of a 12-week self-selected resistance training (SSRT) program on physical fitness and psychophysiological responses among physically inactive older women. We randomly allocated 32 inactive older women (M age = 66.0 years, SD = 3.0) into either an SSRT (n = 16) or control group (n = 16). Participants performed SSRT three times per week over 12 weeks. We assessed maximal isotonic and isokinetic muscle strength, functional capacity, flexibility, cardiorespiratory fitness, and body composition at baseline and after the intervention. Affective responses and perceived exertion were evaluated after each exercise set throughout the training program. The SSRT group significantly improved their maximal muscle strength in all exercises (Cohen’s d ranging from 1.4-3.3; all p’s < .001), peak torque (knee flexors: d = 1.7; knee extensors: d = 1.6; all p < .001), flexibility (knee flexors: d = 1.7; single hip flexors: d = 1.6; all p < .001; bilateral hip flexors: d = 1.1, p = .001), fat-free mass (d = .9, p = .008), and cardiorespiratory fitness (d = .9, p = .014), compared to the control group. All components of functional capacity improved compared to the control group (Cohen’s d ranging from .8 to 5.5; all p’s ≤ .001). Participants perceived the exercise training sessions as pleasant and of low to moderate effort. Thus, a 12-week SSRT program was effective at improving physical fitness and inducing feelings of pleasure among inactive older women.

Abstract Background Different physical activities are widely recommended as non-pharmacological therapies to reduce blood pressure. However, the effectiveness of exercise programs is associated with its continuity and regularity, and the long-term adherence to traditional exercise interventions is often low. Recreational sports emerge as an alternative, being more captivating and able to retain individuals for longer periods. Besides, sport interventions have demonstrated improvements in physical fitness components that are associated with a lower incidence of hypertension. However, no studies have investigated the effects of recreational sports on 24 h ambulatory blood pressure. The aim of the present study is to evaluate the effect of beach tennis training on ambulatory blood pressure and physical fitness in individuals with hypertension. Methods This study will be a randomized, single-blinded, two-arm, parallel, and superiority trial. Forty-two participants aged 35–65 years with previous diagnosis of hypertension will be randomized to 12 weeks of beach tennis training group (two sessions per week lasting 45–60 min) or a non-exercising control group. Ambulatory (primary outcome) and office blood pressures, cardiorespiratory fitness, muscle strength/power and quality of life will be assessed at baseline and after the intervention period. Discussion Our conceptual hypothesis is that beach tennis training will reduce ambulatory blood pressure and improve fitness parameters in middle-aged individuals with hypertension. The results of this trial are expected to provide evidences of efficacy of recreational beach tennis practice on blood pressure management and to support sport recommendations for clinical scenario in higher risk populations.

This study analyzed the effects of an exercise training program consisting of a knee joint complex exercise device (leg-link system) with digitally controlled active motion function and squat movement on physical fitness and gait ability of elderly women aged 70 or above. Fifty four (54) elderly women aged 70 or above were divided into three groups as control group (n = 18), aerobic training group (n = 18), and combined training group with resistance and aerobic exercise (n = 18). Health-related physical fitness, gait ability-related physical fitness, and the temporal and spatial parameters of gait ability were compared. The health-related physical fitness after the 12-week training was not significantly altered in control group, whereas combined training group showed significant increase in all factors (p < 0.05) and aerobic training group showed significant increase (p < 0.05) only in the physical efficiency index. The gait ability-related physical fitness and all items of the temporal and spatial parameters of gait were found to have significantly increased (p < 0.05) in combined training group after the 12-week exercise training; however, in aerobic training group, only the factors related to muscular endurance and balance showed significant increase (p < 0.05). This study suggested that the exercise training consisting of knee joint complex exercise with digitally controlled active motion function and squat exercise for strengthening lower extremities and core muscles had positive effects on enhancing the ambulatory competence in elderly women.

<b><i>Introduction:</i></b> Up to now, there is limited clarity on factors that determine the effectiveness of childhood obesity interventions. <b><i>Objective:</i></b> This study intends to uncover individual- and program-level predictors of BMI-SDS and fitness to achieve significant, sustainable health improvements. <b><i>Methods:</i></b> Data of 249 children with obesity or overweight who participated in an outpatient multidisciplinary program were analysed and compared to 54 waitlist controls. Linear regression models were used to examine associations between individual- and group-level variables and BMI-SDS and fitness. <b><i>Results:</i></b> Among intervention children, BMI-SDS decreased by 0.19 units and physical fitness increased by 11.5%, versus a BMI-SDS decrease of 0.07 and a 1.8% decrease in fitness in the control group. Participants who reported being physically active before the program start achieved greater improvements in BMI-SDS (β = –0.177, <i>p</i> &#x3c; 0.05) and physical fitness (β = 0.174, <i>p</i> &#x3c; 0.05) than inactive peers. BMI-SDS decreased significantly more for members of gender-heterogeneous groups (β = 0.194, <i>p</i> &#x3c; 0.05) with a narrow age range (β = 0.152, <i>p</i> &#x3c; 0.05). <b><i>Conclusions:</i></b> The program under review is effective in counteracting juvenile obesity. The results give reason to believe that forming mixed-gender groups with a small age range and providing increased support for reportedly inactive children may improve program effectiveness.

Introduction. In the changes occurring in competitive sport, proper choice and selection for sport and the age of starting the training are of great importance. Aim. Determining the magnitude of changes in physical fitness and physical development of first-grade children practicing swimming in relation to the non-training peers. Material and methods. The study included two groups of children - the first one was a children practicing swimming (26 boys and 23 girls) and the second one was a non-training class (26 boys and 23 girls). In both groups, MTSF trials were conducted in September and June. The results of the study focused on three aspects: the evaluation of sexual dimorphism, the identification of differences and their direction between groups and sex. Results. There were no statistically significant differences in physical development among children who practiced swimming. There were statistically significant differences in body heights in the non-training group - only in the first study (boys – 120.30; girls – 117.86) also in body weight in the first study (boys – 24.57; girls – 21.22) and also in the second study (boys – 26,80; girls – 22,83). In the assessment of physical fitness, in the group of children training swimming, sexual dimorphism was found in: standing long jump (only in the first study boys – 151,65, girls – 134,96); hand strength measurement (only in the first study boys – 23.5; girls – 19,36); bent arm hang, both in the first study (boys – 13,40; girls – 7,70) and also in the second study (ch-14,46; dz-6,31); forward stretches (only in the first study boys – 5; girls – 1.34); 4x10m run both in the first study (boys – 14,54; girls – 15,23) and also in the second study (boys – 13,66; girls – 15,11). Whereas, in the control group in: standing long jump (also only in the first study boys – 107.78; hand strength measurement in both the first study (boys – 18,95; girls – 12,26) as in the second study (boys – 12,09; girls – 12,77); bent arm hang (only in the first study (boys – 8.21; girls – 3.02); forward stretches in both the first (boys – 2,43; girls – 1,30) as in the second study (boys – 3,30; girls – 2,19). Conclusions. In both groups, boys as well as girls reported statistically significant changes in physical development, which is a normal symptom of growth, but only in the group of girls a statistically significant increase in BMI occured. In evaluating swimming training and its effect on fitness, it can be stated that the boys were positively influenced by such tests as (bent arm hang and sit-ups) and negatively by 50 m and 600 m run. On the other hand, among girls: positive only in the sit-ups test, and negative, as in the group of boys in at 50 m and 600 m run. In the group of girls, it was also noted that the trainees, despite the fact that in the first study achieved a significantly better result in the bent arm hang test, in the second attempt they obtained a considerably weaker result, while the non-training girls in the second measurement achieved a statistically better result than the first one.

This article studies the effects of arthroscopic imaging treatment and clinical rehabilitation of knee sports injuries. Arthroscopy was used to perform meniscus trimming and resection for 40 patients with knee sports injuries. The ages of the patients ranged from 20 to 60 years old. All patients received routine rehabilitation training such as continuous passive motion of the knee joint, biofeedback of the lower limbs, and air pressure therapy of the lower limbs. In addition, the control group was given muscle strength training, and the training began after the patients received the quadriceps muscle strength test. The removal of the joint cavity and the joint debridement has achieved satisfactory treatment results. In the experiment, the test cases were divided into two groups, and the sensor test platform was used for signal collection. Normal activities can be resumed 2 weeks after the operation. After a follow-up of 6 to 24 months, the knee joint pain disappeared, the joint was free of swelling, and the knee function was normal up to 93%. Arthroscopic reconstruction of the anterior and posterior cruciate ligament joint repair/reconstruction of the medial and posterolateral ligament knots is safe and feasible for the treatment of multiple ligament injuries of the knee joint. It has the advantages of less trauma and quick recovery. Early postoperative systemic and standardized rehabilitation exercises can obtain good knee joint function.
