For 10 weeks, the EG practiced SGA® self-postures and the CG practiced assorted calisthenic exercises. All of them were submitted to a variety of tests (before and after): handgrip strength, flexibility, upper limbs' muscle power, isometric pull-up force, lower limbs' muscle power (squat-jump - SJ and countermovement jump - CMJ) and test. Due to the small number of people in the sample, the data were considered non-parametric and then we applied the Wilcoxon test using the software R version 3.3.2 (R Development Core Team, Austria). The effect size was calculated and considered statistically significant the values p ≤ 0.05. Concerning the results, the EG statistical differences were ...

The sample consisted of 90 students (17.02 ± 1.24 years) randomly allocated into three groups of 30 participants each: stretching (SG) proprioceptive neuromuscular facilitation (PNFG) and control (CG). Joint range was measured by goniometry using the LABIFIE protocol and the Lafayette Goniometer Set (360o)– USA as measuring instrument. The scale of perceived exertion in flexibility – PERFLEX (0 – 110) was applied to control intensity in the SG (31- 60) for 5 seconds and the PNFG (61 and 80) for 8 seconds for each phase. Three series, five seconds apart, were conducted. Comparative analysis of joint range levels determined by analysis of variance (one-way ANOVA) and Tukey’s post-hoc test revealed differences only in PNFG: HSF (∆%=4.6; p=0.0...

However, the analysis process of a thermographic image needs to be meticulous to make an appropriate decision. The adipose tissue is considered a potential influence factor in the skin temperature (Tsk) values obtained by IRT. This study aimed to verify the influence of body fat percentage (%BF) on Tsk measured by IRT in male adolescents. A total of 100 adolescents (16.79 ± 0.97 years old and body mass index of 18.41 ± 2.32 kg/m²) was divided into two groups through the results of a dual-energy X-ray absorptiometry analysis: obese (n = 50, %BF 30.21 ± 3.79) and non-obese (n = 50, %BF 11.33 ± 3.08). Thermograms were obtained by a FLIR T420 infrared camera and analyzed by ThermoHuman® software version 2.12, subdividing the body into seven regions of interest (ROI). The results showed that obese adolescents presented lower mean Tsk values than the non-obese...

Materials and method: Sixteen amateur soccer players were supplemented with creatine (n=8) or maltodextrin (placebo, n=8) for four weeks, using a loading protocol (20g/day in the first week, followed by 5g/day for the rest of the study period). Anthropometric measurements and three physical tests were performed before and after the intervention. Results: After the protocol, the Cr group showed increased body mass (pre 65.1 ± 8.2; post 66.4 ± 8.4; p=0.002), arm (pre 27.7 ± 4.3; post 28.3 ± 4.3; p=0.01), thigh (pre 49.9 ± 4.3; post 51.3 ± 4.6; p=0.012), and leg (pre 34.6 ± 2.3; post 34.8 ± 2.4; p=0.029) circumferences. For bangsbo repeat vertical jump test (BRVJ), there was an increase in maximum power (pre 2965.4 ± 691.8; post 3102.1 ± 818; p=0.034), maximum relative power (pre 44.5 ± 6.5; post 47.1 ± 6.5; p=0.045) and average power (pre 2757.6 ± 653.2; post 2937.7 ± 739.9; p=0.05) only in the Cr group. For running anaerobic sprint test (RAST), there was a significant improvement in average sprint and total times, and in the average power for both groups; however, only the Cr group showed significant improvement in maximum power (pre 517.93 ± 118.82; post 580.15 ± 119.06; p=0.01) and maximum relative power (pre 7.9 ± 1.2; post 8.5 ± 1.3; p<0.001). For wingate test (WIN), improvements were observed in maximum power (pre 456.4 ± 91.0; post 508 ± 79.7; p=0.003), maximum relative power (pre 7.0 ± 0.9; post 7.6 ± 0.6; p=0.012), average power (pre 354.8 ± 69.5; post 410 ± 71.5; p<0.001) and relative average power (pre 5.4 ± 0.6; post 6.1 ± 0.4; p=0.012) only in the Cr group. Conclusions: This study findings demonstrated that Cr supplementation during four weeks promotes positive anthropometric and anaerobic performance changes in college soccer players, especially in lower limbs, but also in upper limbs. However, a possible body mass gain with its use should be considered, so the viability should be individually analysed.

However, the subcutaneous adipose tissue can act as an insulator when the Tsk is assessed by IRT, modifying the normal Tsk data and leading to their misinterpretation. Considering that the body mass index (BMI) is an important predictor of obesity, the objective of this study was to verify if the Tsk measured by IRT is affected by the BMI in adolescents. A preliminary study was carried out being four participants intentionally selected, all 16 years old, each one classified in a different BMI range according to the criteria of the World Health Organization for the adolescent population: underweight, healthy weight, overweight and obesity. Four thermograms of each participant were recorded and the ThermoHuman® software was used to evaluate 82 regions of interest (R...

This study analyzed the behavior of Tsk of the same muscle groups when exercised with different demands in rowing. Methods: Eighteen men underwent three performance tests on a rowing ergometer: whole-body 2,000 m test (RTWB), upper-body (RTUB), and lower-body (RTLB) tests. In each condition, thermograms were recorded before (pre), immediately after test (post), and at 10 (REC10), 20 (REC20), and 30 (REC30) minutes post-exercise recovery. Tsk was measured at the pectoral (control body region), upper back, quadriceps, brachial biceps, and forearm. Results: Pectoral-Tsk reduced comparably in response to all testing conditions (p < .05). Upper back-Tsk decreased post (p < .001) and returned to baseline in the RTUB (REC10, p = 1.0) and RTWB (REC30, p = .128), while remained reduced in the RTLB (p < .001). Quadriceps-Tsk reduced post (p < .05) and returned to baseline in the RTWB and RTLB at REC10 (p = 1.0), remaining reduced in the RTUB during recovery (p < .05). Regarding the upper limbs, Tsk increased more markedly in the RTUB versus RTWB during the recovery period (p < .05); in the RTLB, biceps-Tsk remained below baseline over time (p < .05), whereas the forearm-Tsk was restored at REC10 (p = 1.0). Conclusion: Manipulating the muscle groups involved in rowing alters the Tsk response within equal ROI. Exercise-induced Tsk changes can reflect local hemodynamic and thermoregulatory adjustments.

The type of exercise may have a specific impact on skin temperature (Tsk). Objective: To analyze and compare the behavior of Tsk in a resistance training between men and women and monitor the thermal recovery response. Material and Methods: Sixteen male and female adults (24.56 ± 3.22 years old) underwent a resistance circuit training session. They performed 3 sets of 12 repetitions with 70-80% 1 RM for lat pulldown, leg press, and biceps arm curl exercises. Thermograms were taken in anterior and posterior body view at rest, 20 min, and 24 h after training. Tsk was measured in the body regions of interest corresponding to the brachial biceps, quadriceps, and upper back. ANOVA with Tukey's post hoc test was used to analyze Tsk changes among moments, and independent samples t-test was used to compare Tsk between males and females. Results: At rest, women showed Tsk significantly lower than men. There was no significant Tsk change 20 min after exercise. However, Tsk increased 24 h after exercise in the upper back for men compared with baseline and in quadriceps for women compared with baseline and 20 min after exercise (p < 0.05). Conclusion: The Tsk of women at rest is lower than that of men. A resistance circuit training session does not significantly change Tsk 20 min after exercise, but it increases Tsk 24 h after training in the upper back for men and quadriceps for women.

Sixteen young active men (22.5±2.1 yrs.) performed a progressive test up to 85% of HRmax. Thermograms of the trunk, Upper Limbs (UL) and Lower Limbs (LL) were recorded at rest (REP), immediately after exercise (PEX) and every 15 minutes during 60 minutes of recovery (R15 to R60). Ten regions of interest (ROIs) were manually selected from each thermogram. A repeated measures ANOVA was applied to assess thermal variations over time. There was a significant decrease in temperature in Chest, Abdomen, Superior Back, Lumbar, Anterior and Posterior Thigh, Anterior and Posterior Leg PEX (∆≤-1.5oC vs REP; p<0.001 for all comparison); however, the Tsk increased after 15 minutes of recovery in these same ROI (∆≤0.7oC vs REP; p<0.05 for all comparisons, except Anterior Thigh; p=0.167). All Arm ROIs showed the opposite behavior, where there was a progressive increase in Tsk up to 15 min post-exercise (∆≤1.0oC vs REP; p<0.01 for all comparison), followed by a progressive decrease. The progressive submaximal upper limbs exercise increased the Tsk in active areas (arms) and induced a significant decrease of Tsk in others.

Materials and method: Nine male participants (23.0±2.5 years old) underwent three 45-minute moderate-intensity running sessions (60-70% reserve heart rate) on a treadmill. At each session, a different experimental condition was applied in a crossover design: without airflow (NF), and with low (LF) and high airflow (HF) generated by a fun. Thermograms were obtained with a thermal camera before exercise, during (every 10 minutes), and after exercise. Skin temperature (Tsk) was measured on regions of interest of the upper body: pectoral, brachial biceps, and upper back. A repeated measures ANOVA was used to compare Tsk over time and between conditions, considering p<0.05 as statistically significant. Results: In pectoral and brachial biceps, LF and HF conditions provided greater reductions in Tsk at all moments when compared to the NF (p<0.05). There ...

Temperatura cutânea. Regulação da temperatura corporal. RESUMO Comparou-se a resposta da temperatura da pele (T P) entre o exercício intenso de curta duração e moderado prolongado. Dezoito homens realizaram o teste de 2000 m (T 2000m) e um protocolo de exercício moderado (45 minutos) em remoergômetro. Termogramas foram obtidos antes e após os protocolos, e com 10, 20 e 30 minutos de recuperação. Utilizou-se ANOVA Two-Way com post hoc de Tukey para comparar a T P. No peitoral a T P reduziu após o T 2000m (p < .001) e exercício moderado (p = .003) e retornou ao baseline apenas no moderado (p = .489). Na região dorsal superior (DS) a T P reduziu após os exercícios (p < .001) e retornou ao baseline 30 minutos após o T 2000m (p = .56) e 10 minutos após o exercício moderado (p = .95). No quadríceps a T P reduziu após os exercícios (p = .03) e retornou ao baseline com 10 minutos de recuperação (p = .974). No biceps braquial (BB) a T P aumentou em relação ao baseline durante a recuperação (p < .001). O exercício intenso de curta duração e moderado prolongado em remoergômetro proporcionam respostas térmicas diferenciadas no peitoral e DS. No BB e quadríceps as respostas térmicas são equivalentes entre estes exercícios.
