“…Five of eleven national guidelines concerning exercise in pregnancy recommend resistance exercise (2). Our results show that resistance exercise in the second trimester of normotensive pregnancy does not seem to negatively impact BP, concurring with Bgeginski et al (10) who recently showed that BP response to resistance exercise was within healthy limits and significantly lower in a pregnant group than in a matched non-pregnant group. Pregnancy itself causes a decrease in BP due to reduction of peripheral vascular resistance (17), which might represent a protective effect on cardiovascular health in early to mid-pregnancy (11).…”

“…Amorim et al (9) concluded that maternal BP levels were slightly increased during aerobic exercise, followed by a substantial hypotensive effect hours after the exercise session. Recently, Bgeginski et al (10) showed that BP response to resistance exercise is unaffected by pregnancy and this has been demonstrated to remain within safe margins during exercise. Finkelstein et al (11) concluded that there was no difference in cardiovascular response between pregnant and nonpregnant women during land or water exercise, although BP response was lower during exercise in water.…”

“…Our results show that the combination of aerobic and resistance exercise in both the second and third trimesters of pregnancy does not induce unsafe changes in blood pressure. Furthermore, Bgeginski et al reported that blood pressure, together with FHR, stayed within normal limits during resistance exercise in pregnant women.…”

Research on the acute responses to exercise in pregnancy is scarce, especially for women affected by gestational diabetes mellitus (GDM). The aim of this study was to investigate responses to a single bout of exercise performed multiple times throughout the pregnancy in women diagnosed with GDM. Data from 18 pregnant women (aged: 32.8 ± 3.8) diagnosed with GDM, treated with diet only, were analyzed. Participants' pre-pregnancy body mass index was 24.4 ± 4.9 kg/m , 50% of them were nulliparous, and 50% of the sample regularly exercised before the pregnancy. The exercise intervention consisted of an individual structured aerobic and resistance exercise program performed twice per week from the time of diagnosis until at least the 36th week of pregnancy. The exercise program included 20 minutes of aerobic exercise, 20-25 minutes of resistance exercise, and 10 minutes of cool down. Maternal heart rate, systolic and diastolic blood pressure, temperature and fetal heart rate were measured at every exercise session, along with blood glucose on 3 occasions. In total, 365 exercise sessions were analyzed (85 in the second trimester and 280 in the third trimester), on average 20.3 ± 7.7 per participant. Heart rate and fetal heart rate were elevated during both the aerobic and resistance parts of the exercise session (P < .01) in comparison with the baseline while systolic and diastolic blood pressure did not change in the total sample. There was a slight elevation in tympanic membrane temperature during the aerobic part of the session (P < .01). All parameters returned to baseline levels by the end of the session. Glucose levels dropped from the baseline, from 4.7 ± 0.6 to 3.9 ± 0.4 mmol/L (P < .01). There were no differences in responses to exercise between the second and third trimesters, nor between pre-pregnancy exercisers and non-exercisers. The combination of aerobic and resistance exercise for women diagnosed with GDM does not have harmful short-term effects if performed according to guidelines. Likewise, exercise can be considered useful for controlling hyperglycemia in pregnancy for women affected by GDM.

“…The exercise protocol has been published previously 14 . The muscles mainly activated during the exercise in the bilateral leg extension are the quadriceps femoris, and during the exercise in the pec-deck fly, the pectoralis major and anterior deltoid muscles are activated.…”

PURPOSE: To determine fetal heart rate (FHR) responses to maternal resistance exercise for the upper and lower body at two different volumes, and after 25 minutes post-exercise. METHODS: Ten pregnant women (22-24 weeks gestation, 25.2±4.4 years of age, 69.8±9.5 kg, 161.6±5.2 cm tall) performed, at 22-24, 28-32 and 34-36 weeks, the following experimental sessions: Session 1 was a familiarization with the equipment and the determination of one estimated maximum repetition. For sessions 2, 3, 4 and 5,FHR was determined during the execution of resistance exercise on bilateral leg extension and pec-deck fly machines, with 1 and 3 sets of 15 repetitions; 50% of the weight load and an estimated repetition maximum. FHR was assessed with a portable digital cardiotocograph. Results were analyzed using Student's t test, ANOVA with repeated measures and Bonferroni (α=0.05; SPSS 17.0). RESULTS: FHR showed no significant differences between the exercises at 22-24 weeks (bilateral leg extension=143.8±9.4 bpm, pec-deck fly=140.2±10.2 bpm, p=0.34), 28-30 weeks (bilateral leg extension=138.4±12.2 bpm, pec-deck fly=137.6±14.0 bpm, p=0.75) and 34-36 weeks (bilateral leg extension=135.7±5.8 bpm, pec-deck fly=139.7±13.3 bpm, p=0.38), between the volumes(bilateral leg extension at 22-24 weeks: p=0.36, at 28-30 weeks: p=0.19 and at 34-36 weeks: p=0.87; pec-deck fly at 22-24 weeks: p=0.43, at 28-30 weeks: p=0.61 and at 34-36 weeks: p=0.49) and after 25 minutes post-exercise. CONCLUSION: Results of this pilot study would suggest that maternal resistance exercise is safe for the fetus. ResumoOBJETIVO: O objetivo do presente estudo foi determinar a frequência cardíaca fetal (FCF) enquanto gestantes realizavam exercícios de força para os membros superiores e inferiores, com dois volumes diferentes, e 25 minutos pós-exercício. MÉTODOS: Dez gestantes (22-24 semanas, 25,2±4,4 anos, 69,8±9,5 kg, 161,6±5,2 cm) realizaram as seguintes sessões experimentais com 22-24, 28-32 e 34-36 semanas de gestação: A Sessão 1 foi a familiarização com os equipamentos e determinação de uma repetição máxima estimada. Para as Sessões 2, 3, 4 e 5, foi determinada a FCF durante a execução do exercício de força nos equipamentos extensão de joelhos bilateral e voador, com 1 e 3 séries de 15 repetições e carga de 50% de uma repetição máxima estimada. A FCF foi avaliada com um cardiotocógrafo digital portátil. Os resultados foram analisados com teste t de Student, ANOVA com medidas repetidas e Bonferroni (α=0,05; SPSS 17.0). RESULTADOS: A FCF não demonstrou diferença significativa entre os exercícios com 22-24 semanas (extensão de joelhos bilateral=143,8±9,4 bpm, voador=140,2±10,2 bpm, p=0,34), 28-30 semanas (extensão de joelhos bilateral=138,4±12,2 bpm, voador=137,6±14,0 bpm, p=0,75) e 34-36 semanas (extensão de joelhos bilateral=135, 7±5,8 bpm, voador=139,7±13,3 bpm, p=0,38), entre os volumes (extensão de joelhos bilateral com 22-24 semanas: p=0,36, 28-30 semanas: p=0,19 e 34-36 semanas: p=0,87; voador com 22-24 semanas: p=0,43, 28-30 semanas: p=0,61 e 34-36 ...
