The purpose of this study was to characterize high-intensity functional training (HIFT) in physically inactive adults. Four men and 10 women who were inexperienced with HIFT and not performing regular physical activity performed HIFT 3 days/week for 8 weeks. Health and fitness measures were assessed before and after the intervention. Resting heart rate (73 ± 12 vs. 68 ± 11 bpm) and resting diastolic blood pressure (71 ± 7 vs. 65 ± 6 mmHg) were reduced, while resting systolic blood pressure remained unchanged. Absolute VO2max (2.53 ± 0.68 vs. 2.69 ± 0.66 L/min) and relative VO2max (32.51 ± 8.84 vs. 34.31 ± 8.63 mL/kg/min) were improved. Lean body mass (48.20 ± 13.37 vs. 49.26 ± 13.81 kg) was increased, but fat mass was unchanged. Performance on the leg press (164.61 ± 54.35 vs. 201.62 ± 67.50 kg), bench press (39.12 ± 20.15 vs. 46.43 ± 21.18 kg), YMCA bench press (26 ± 13 vs. 37 ± 16 reps), one-minute sit-up (25 ± 9 vs. 32 ± 10 reps), and sit-and-reach (30.36 ± 11.36 vs. 32.14 ± 9.66 cm) were all increased. High-intensity functional training may be useful for improving health-related physical fitness parameters in physically inactive adults.

The present study examined the effects of a functional high-intensity suspension training (FunctionalHIIT) on resting blood pressure, psychological well-being as well as on upper body and core strength and cardiorespiratory fitness in moderately trained participants. Twenty healthy, moderately trained adults (10 males and 10 females; age: 36.2 ± 11.1 years, BMI: 23.9 ± 3.7) were randomly assigned to a FunctionalHIIT training group or passive control group (CON). FunctionalHIIT performed 16 sessions (2× week for eight weeks, 30 min per session), whereas CON maintained their habitual lifestyle using a physical activity log. Before and after FunctionalHIIT intervention, resting blood pressure and quality of life (short version of the WHO Quality of Life questionnaire (WHOQOL-BREF)) were assessed. Furthermore, maximum-repetition (leg press, chest press, pulldown, back extension) and trunk muscle strength (Bourban test) as well as cardiorespiratory fitness (Vameval test), were measured before and after the intervention. Both systolic and diastolic blood pressure and WHOQOL-BREF did not change significantly but both showed moderate training-induced effects (0.62 < standardized mean difference (SMD) < 0.82). Significant improvements in the FunctionalHIIT group were evident on leg press (p < 0.01), chest press (p < 0.05), and left side Bourban test (p < 0.05). Cardiorespiratory fitness did not reveal any time effects or time × group interactions. The present study revealed that eight weeks of FunctionalHIIT represents a potent stimulus to improve health-related parameters in young adults, whereas FunctionalHIIT was not sufficient to improve cardiorespiratory fitness.

Physical training is used in the control of arterial hypertension (AH), especially in patients with higher levels of blood pressure (BP). However, there are still few studies on the effects of physical training on AH in less advanced stages of the disease. The aim of the present study was to assess the immediate and late acute effects of continuous moderate physical training (CMT) and high intensity interval training (HIIT) in patients with mild AH, and to assess which training method induces a greater hypotensive effect. A female patient, 43 years old, sedentary, diagnosed with mild AH (stage 1), taking Losartana 50 mg twice a day was studied. She underwent one CMT and one HIIT session, one week apart. BP measurements were taken before and after each session, as well as 24 hours before and after the sessions. After the physical training sessions, we observed a drop in the patient's BP that lasted up to 60 minutes, and a reduction in blood pressure levels on the day after the training. We conclude that both training modalities were efficient in reducing the BP of the patient with mild acute immediate and delayed hypertension.

The purpose of this study was to determine the effects of the herbal preparation Tribulus terrestris (tribulus) on body composition and exercise performance in resistance-trained males. Fifteen subjects were randomly assigned to a placebo or tribulus (3.21 mg per kg body weight daily) group. Body weight, body composition, maximal strength, dietary intake, and mood states were determined before and after an 8-week exercise (periodized resistance training) and supplementation period. There were no changes in body weight, percentage fat, total body water, dietary intake, or mood states in either group. Muscle endurance (determined by the maximal number of repetitions at 100—200% of body weight) increased for the bench and leg press exercises in the placebo group (p < .05; bench press ±28.4%. leg press ±28.6%), while the tribulus group experienced an increase in leg press strength only (bench press ±3.1 %, not significant; leg press ±28.6%, p < .05). Supplementation with tribulus does not enhance body composition or exercise performance in resistance-trained males.

CrossFit (CF; CrossFit Inc., Washington, DC, USA) is a form of high-intensity functional training that focuses on training across the entire spectrum of physical fitness. CF has been shown to improve a number of indicators of health but little information assessing energy balance exists. The purpose of the present study was to investigate energy balance during 1 week of CF training. Men and women (n = 21; mean ± SD; age, 43.5 ± 8.4 years; body mass index, 27.8 ± 4.9 kg·m−2), with ≥3 months CF experience, had body composition assessed via air displacement plethysmography before and after 1 week of CF training. Participants wore ActiHeart monitors to assess total energy expenditure (TEE), activity energy expenditure, and CF energy expenditure (CF EE). Energy intake was assessed from TEE and Δ body composition. CF EE averaged 605 ± 219 kcal per 72 ± 10 min session. Weekly CF EE was 2723 ± 986 kcal. Participants were in an energy deficit (TEE: 3674 ± 855 kcal·day−1; energy intake: 3167 ± 1401 kcal·day−1). Results of the present study indicate that CF training can account for a significant portion of daily activity energy expenditure. The weekly expenditure is within levels shown to induce clinically meaningful weight loss in overweight/obese populations.

Caffeine (CAF) exerts a pressor effect both at rest and during exercise, as blood pressure is higher than with placebo. The effect of acute CAF ingestion combined with intense resistance training on cardiovascular function is unknown, however. The primary aim of the study was to examine changes in cardiovascular function after completion of fatiguing bench-press and leg-press exercise after CAF or placebo ingestion. Twenty-two resistance-trained men ingested CAF (6 mg/kg) or placebo 1 h pre exercise in a randomized, double-blind crossover design. They refrained from CAF intake and strenuous exercise 48 and 24 h pretrial, respectively. Heart rate and blood pressure were measured pre exercise. After a standardized warm-up, 1-repetition-maximum (1-RM) on the barbell bench press and leg press was tested. When it had been determined, a load equivalent to 60% of 1-RM was placed on the bar, and the subject completed repetitions to failure. Measurements of heart rate and blood pressure were immediately completed, and mean arterial pressure and rate-pressure product were calculated. Results showed significant (P < 0.05) increases in heart rate (+ 10 beats/min), systolic blood pressure (+ 8–10 mmHg), and rate-pressure product with acute CAF ingestion versus placebo. No change (P > 0.05) in diastolic blood pressure across time or treatment was shown. To prevent elevated blood pressure and potential enhanced risk of heart disease, CAF intake should be monitored in at-risk men who participate in resistance training.

AIM: The aim of this study was to examine whether the addition of high-load resistance exercises to a high-intensity functional training (HIFT) program elicits further improvements in physical fitness-related parameters and body composition. Material & Method: Twenty recreationally active volunteers (8 male, 12 female; age, 30 ± 4 y; body mass, 65.8 ± 12.7 kg; height, 167 ± 7 cm) were randomly assigned to a HIFT-control (HIFT-C, n = 10) or HIFT-power group (HIFT-P, n = 10) and trained 3 times per week for 8 weeks. The HIFT-C protocol consisted of four rounds of an 8-exercise circuit (30:15 s work:rest, 2 min rest after round 2), which included clean-and-press jump box, TRX chest press, wall ball throws, burpees, repeated 10 m sprints, sumo squat-and-upright row (at 65% 1RM), and abdominal crunches. The HIFT-P group replaced the TRX chest press with bench chest press and the squat-and-upright row with squat at 80% 1RM. Before and after training, participants underwent evaluation of body composition, cardiorespiratory fitness (VO2max), vertical jump, 1RM bench press, and maximum number of abdominal crunches in 1 min. Two-way repeated-measures ANOVA was used to analyze results. Statistical significance was set at p < 0.05. Results: After 8 weeks the following parameters improved in both groups: VO2max (5.2 ± 5.4%, p = 0.003), squat jump (10.9 ± 9.8%, p < 0.001), countermovement jump (8.0 ± 6.0%, p < 0.001), bench press 1RM (18.6 ± 19.6%, p < 0.001), and body fat mass (0.82 ± 1.65 kg, p < 0.001). However, muscle mass increased only in HIFT-P (3.3 ± 2.3%, p = 0.002) and abdominal muscle endurance improved only in HIFT-C (16.2 ± 12.2%, p = 0.002). Conclusions: Short-term HIFT resulted in improvements in whole-body cardiorespiratory and neuromuscular fitness and reduction of body fat. The addition of high-load resistance exercises to a HIFT training program was well tolerated and resulted in increased muscle mass.

Background: High-intensity functional training can be well performed by the elderly; however, the effect of this training on brain-health-related factors has not been studied yet. Therefore, this study aimed to investigate the effect of eight weeks of high-intensity functional training on serum levels of BDNF, IGF-1, and VEGF in elderly men and women. Materials and Methods: This quasi-experimental study included 23 subjects (7 males and 16 females) who were divided into experimental (n=16) and control groups (n=7). The experimental group performed a training protocol consisting of six exercises in three sessions (each session was 25 min) per week for eight weeks. The exercises were performed at all-out intensity for 30 sec. There was a 15-sec rest between each set and a two-min rest between each exercise. Paired samples t-test and ANCOVA were used to analyze the data, and a p-value less than 0.05 was considered statistically significant. Results: The results showed that the serum levels of BDNF (P=0.0005, +11.37), VEGF (P=0.0005, +7.49), IGF-1 (P=0.001, +3.91), LDL (P=0.004, -3.33), and HDL (P=0.004, +7.48) changed significantly in the experimental group. On the other hand, in the control group, serum levels of BDNF (P=0.149, +1.58), IGF-1 (P=0.486, +0.27), LDL (P=0.897, +0.14), and HDL (P=0.534, +1.10) had no significant changes; however, VEGF (P=0.01, +0.67) significantly changed. The results of ANCOVA showed a significant difference between the two groups regarding all variables (P<0.05). Conclusion: Eight weeks of high-intensity functional training in elderly men and women increases the serum levels of brain health-related factors. Therefore, functional training is recommended to improve brain function in the elderly.

The Difference

It is known that systolic blood pressure (SBP) drops five to seven mmHg for 22 hours immediately after a workout in individuals the have moderate hypertension, and that in individuals with optimal blood pressure (BP), one can expect to see a drop of four to five mmHg for over the following 22 hours. Creatine (CRE), one of the most recognized supplemental aids to enhance performance of high-intensity exercise, has convincingly substantiated its ergogenic potential (Naderi et al. 2016). However, little has been researched on the connection between creatine and blood pressure. The purpose of this study was to examine the effects of CRE on BP after a bout of high intensity strength training on Division III football players at Gustavus Adolphus College. This study is a one sample research design. Each athlete had their blood pressure measured four total times. One resting BP was taken before the consumption of CRE and the other was taken 18-22 hours after the consumption of creatine. The same was done when each subject participated in the control group as well. The subjects were given the creatine or placebo (control) at random for their first trial and then given the opposite for the second trial one week later. The independent variable was consumption of CRE. The dependent variables were SBP and diastolic blood pressure (DBP). The difference in SBP and DBP between the trials were calculated and analyzed using a paired sample t-test. Results showed that CRE trial BPs were slightly higher than in control trials although the difference was not significant (p&lt;0.05). The results of the study gave a better understanding of the effects of CRE on BP after a high intensity strength training session.

Post Exercise Hypotension

Background and objective: Post-exercise hypotension, the reduction of blood pressure after a bout of exercise, is of great clinical relevance. Resistance exercise training is considered an important contribution to exercise training programs for hypertensive individuals and athletes. In this context, post-exercise hypotension could be clinically relevant because it would maintain blood pressure of hypertensive individuals transiently at lower levels during day-time intervals, when blood pressure is typically at its highest levels. The aim of this study was to compare the post-exercise cardiovascular effects on Paralympic powerlifting athletes of two typical high-intensity resistance-training sessions, using either five sets of five bench press repetitions at 90% 1 repetition maximum (1RM) or five sets of three bench press repetitions at 95% 1RM. Materials and Methods: Ten national-level Paralympic weightlifting athletes (age: 26.1 ± 6.9 years; body mass: 76.8 ± 17.4 kg) completed the two resistance-training sessions, one week apart, in a random order. Results: Compared with baseline values, a reduction of 5–9% in systolic blood pressure was observed after 90% and 95% of 1RM at 20–50 min post-exercise. Furthermore, myocardial oxygen volume and double product were only significantly increased immediately after and 5 min post-exercise, while the heart rate was significantly elevated after the resistance training but decreased to baseline level by 50 min after training for both training conditions. Conclusions: A hypotensive response can be expected in elite Paralympic powerlifting athletes after typical high-intensity type resistance-training sessions.
