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.

High-intensity exercise has been found to positively influence glucose control, however, the effects of high-intensity functional training (HIFT) for overweight and obese sedentary adults without diabetes is unknown. The purpose of this study was to examine changes in body composition and glucose control from eight weeks of aerobic and resistance training (A-RT) compared to HIFT. Session time spent doing daily workouts was recorded for each group. Baseline and posttest measures included height, weight, waist circumference, dual X-ray absorptiometry (body fat percentage, fat mass, lean mass), and fasting blood glucose. Participants completing the intervention (78%, n = 9 per group) were 67% female, age = 26.8 ± 5.5 years, and had body mass index = 30.5 ± 2.9 kg/m2. Fasting blood glucose and 2-h oral glucose tolerance tests were used as primary outcome variables. On average, the HIFT group spent significantly less time completing workouts per day and week (ps < 0.001). No significant differences were found for body composition or glucose variables within- or between-groups. Even though our findings did not provide significant differences between groups, future research may utilize the effect sizes from our study to conduct fully-powered trials comparing HIFT with other more traditional training modalities.

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.

Before And After

This study examined the effects of whey and pea protein supplementation on physiological adaptations following 8-weeks of high-intensity functional training (HIFT). Fifteen HIFT men (n = 8; 38.6 ± 12.7 y, 1.8 ± 0.1 m, 87.7 ± 15.8 kg) and women (n = 7; 38.9 ± 10.9 y, 1.7 ± 0.10 m, 73.3 ± 10.5 kg) participated in this study. Participants completed an 8-week HIFT program consisting of 4 training sessions per week. Participants consumed 24 g of either whey (n = 8) or pea (n = 7) protein before and after exercise on training days, and in-between meals on non-training days. Before and after training, participants underwent ultrasonography muscle thickness measurement, bioelectrical impedance analysis (BIA), two benchmark WODs (workout of the day), 1-Repetition Maximum (1RM) squat and deadlift testing, and Isometric Mid-thigh Pull (IMTP) performance. Separate analyses of covariance (ANCOVA) were performed on all measures collected at POST. Both groups experienced increased strength for 1RM back squat (p = 0.006) and deadlift (p = 0.008). No training effect (p > 0.05) was found for body composition, muscle thickness, IMTP peak force, IMTP rate of force development, or performance in either WOD. Using PRE values as the covariate, there were no group differences for any measured variable. We conclude that ingestion of whey and pea protein produce similar outcomes in measurements of body composition, muscle thickness, force production, WOD performance and strength following 8-weeks of HIFT.

Post-menopausal women are at high risk of developing type 2 diabetes mellitus (T2DM) and cardiovascular diseases. Regular physical activity is recommended for treatment of chronic diseases. However, there is still no consensus about the intensity and type of exercise. This study aimed to evaluate the effects of combined functional training intensity on the cardiometabolic parameters of post-menopausal women with T2DM. Ninety-eight post-menopausal women with T2DM enrolled in the public health service of a Brazilian municipality were invited to participate in this study. Sixteen volunteers were divided into the moderate (MI) and high intensity (HI) groups. Functional training was performed 3 times a week. Anthropometric data, blood pressure, heart rate (HR), plasma glucose, glycated haemoglobin, total cholesterol, HDL-C, LDL-C and triacylglyceride (TG) levels were measured. Functional training reduced glycated haemoglobin and blood pressure levels and improved body composition in both groups. HI training improved HDL-C and TG levels, although a reduction in LDL-C was observed only in the MI group. Physical training did not modify the other evaluated parameters. The data showed that 8 weeks of functional training, regardless of intensity, is an effective strategy to improve glucose control and promote health benefits in post-menopausal women with T2DM.
