The present study aimed to verify if blood pressure (BP) reactivity could be reduced through a previous single session of active playing when compared to sedentary leisure. Sixteen pre-pubertal healthy children participated in this study. After familiarization with procedures and anthropometric evaluation, participants performed three sessions in randomized order: (1) 30 min of traditional Brazilian games (PLAY); (2) 30 min of video game playing (DDR); and (3) 30 min of watching TV (TV). Each session lasted 80 min, being 10 min of rest; 30 min of intervention activity; and 40 min of recovery. After recovery, the Cold Pressor Test (CPT) was used for the assessment of acute cardiovascular reactivity. BP was recorded at 30 s and 1 min during the CPT. Analysis of variance showed post-exercise hypotension (PEH) only after PLAY, and that systolic and diastolic BP were significantly increased in all conditions during CPT. However, the magnitude of the CPT-induced BP response was significantly less in PLAY compared to DDR and TV. The PEH observed during recovery and the reduced BP response to CPT following playing traditional games may be due its higher cardiovascular and metabolic demand as was indicated by the increased heart rate, oxygen consumption, and BP. It was concluded that BP reactivity to stress may be reduced through a previous single session of traditional games and that PEH was recorded only after this exercise form. This benefit indicates a potential role of playing strategies for cardiovascular health in childhood.
Souza, LR, Vicente, JB, Melo, GR, Moraes, VC, Olher, RR, Sousa, IC, Peruchi, LH, Neves, RV, Rosa, TS, Ferreira, AP, and Moraes, MR. Acute hypotension after moderate-intensity handgrip exercise in hypertensive elderly people. J Strength Cond Res 32(10): 2971-2977, 2018-Isometric handgrip (IHG) training is effective in reducing blood pressure (BP), but little is known about the occurrence of acute hypotension by postisometric exercise hypotension (PIEH) and the underlying mechanisms. Ten sedentary hypertensive elderly people (7 women and 3 men) individuals, with a mean age of 73.2 ± 2.2 years and systolic BP (SBP) of 135.1 ± 6.5, were included; they were hypertensive for 13.2 ± 3.1 years and were receiving medications. These patients underwent 2 experimental sessions of isometric exercise using a portable hydraulic handgrip dynamometer: (a) sham session with 3% of maximal voluntary isometric contraction (MVIC) and (b) experimental isometric session with 30% MVIC, completing a total of 8 sets of 1-minute contraction and 1-minute rest-pause (overload of work = 51.7 kgf·min). Blood pressure and heart rate were evaluated at rest and 1, 5, 10, 15, 30, 45, and 60 minutes postexercise. Blood lactate (Lac) and salivary nitric oxide (NO) were collected at rest, 0, 30, and 60 minutes postexercise. The SBP presented a reduction as of the tenth minute postexercise to session 30% MVIC (Δ = -14.4 at -18.7 mm Hg, p < 0.05). At 60-minute postexercise, the SBP was 30% lower vs. 3% MVIC (-20.2 mm Hg, p = 0.006). There were no differences for the other cardiovascular parameters and vasoactive substances for both sessions (p > 0.05). These results demonstrated that the IHG exercise with a higher overload of work induced PIEH in hypertensive elderly people, but there was no association with Lac and NO. Therefore, this IHG model with easy execution, quick adherence, short duration, and a portable equipment can be an excellent adjuvant strategy for the control and prevention of hypertension.
The purpose of this study was to compare the effect of a combined exercise session performed at different periods of the day on the 24h blood pressure (BP) response. Anaerobic threshold (AT) and 12 repetition maximum (12RM) tests were evaluated in nine Brazilian jiu-jitsu athletes (male) (22±3.7 y; 176±5.0 cm; 73.4±9.7 kg; 6.8±2.1 % body fat). Four experimental sessions were performed: resistance exercise followed by aerobic exercise [Morning (MornS) and Afternoon (AfternS)] and Control (C) [Morning and Afternoon]. The morning sessions were conducted at 09:00 a.m. and the afternoon sessions were conducted at 3:00 p.m. The resistance exercise consisted of three sets at 90% of a 12RM for six resistance exercises. The aerobic exercise consisted of 15min at 90% of the AT. Blood pressure (BP) was measured before, during and 1h (Microlife® BP3A1C) after the performance of exercises in laboratory, and then during daily activities for the succeeding 23h by ambulatory BP monitoring (Dyna-MAPA®). Analysis of the area under the curve (AUC) indicated significant reductions in blood pressure parameters at various time points during the 24h monitoring period. For systolic BP (SBP), significantly lower values were shown following the morning session versus the control (MornS: 1756.2±100.8 vs. C: 1818.2±84.3 mmHg*15h; p < .05) and total-24h (MornS: 2695.8±143.3 vs. C: 2784.1±143.2 mmHg*24h; p < .05). The total-24h mean BP (MAP) was also significantly lower following the morning session versus the control (MornS: 2015.7±121.2 vs. C: 2087.3±153.8 mmHg*24h; p < .05). There were significant differences in the sleeping AUC of SBP (AfternS: 883.6±27.0 vs. C: 965.2±67.9 mmHg*9h; p < .05), diastolic BP (DBP) (AfternS: 481.4±30.9 vs. MornS: 552.9±34.2 and C: 562.1±52.3 mmHg*9h; p < .01) and MBP (AfternS: 651.9±22.4 vs. MornS: 708.7±43.1 and C: 726.9±64.7 mmHg*9h; p < .01). The combined exercise performed at different periods of the day contributed distinctly to the reduction of BP. The morning session was important in reducing SBP and MBP in the total-24h monitoring, while the afternoon session reduced SBP, DBP and MBP during sleeping in jiu-Jitsu athletes.
El análisis de las relaciones de género en la Educación Física no es un tema nuevo. Sin embargo, los pequeños cambios observados justifican la reelaboración del problema. El objetivo de esta investigación fue evaluar la forma de estructurar las clases, la percepción de los profesores sobre el comportamiento de los estudiantes, y analizar las estrategias utilizadas en una acción positiva sobre el tema. El estudio fue de tipo combinado descriptivo/ exploratorio, en el que participaron diez profesores de Educación Física de la Educación Pública del Distrito Federal que trabajan en la educación primaria. Los resultados apuntan a la necesidad de seguir cuestionando la percepción de los profesores y estudiantes de Educación Física por ser éste un espacio privilegiado para la construcción de la corporeidad, teniendo el potencial para reinventar las relaciones de género.
