High intensity functional training versus traditional resistance training effects on inflammatory, metabolic, and physical outcomes in overweight men a randomized controlled trial.

Neither HIFT nor RT produced significant differences in inflammatory markers between groups.

• Inflammatory markers assessed included IL-4, γ-IFN, MMP-9, and TLR4.
• Blood samples were collected before and after the 8-week training interventions.
• No significant differences in inflammatory markers were detected between the HIFT, RT, and control groups.
• Sample sizes were HIFT (n=13), RT (n=10), and control (n=11).

Both HIFT and RT significantly reduced fasting blood sugar (FBS) compared to baseline.

• The reduction in FBS was statistically significant (p < 0.05) in both training groups.
• The control group did not undergo any training intervention.
• Participants were overweight men with a mean BMI of 27.78 ± 1.47 kg/m².
• Both interventions were performed three times per week for eight weeks.

RT lowered total cholesterol, while triglycerides decreased in both HIFT and RT groups.

• Total cholesterol reduction was specific to the RT group and not observed in the HIFT group.
• Triglyceride reductions were observed in both the HIFT and RT groups.
• HDL, LDL, and total cholesterol were among the metabolic markers assessed.
• Interventions lasted eight weeks with three sessions per week.

Skeletal muscle mass increased significantly in the training groups.

• Skeletal muscle mass increase was described as statistically significant.
• Body composition was evaluated as part of the outcome measures.
• Both HIFT and RT groups participated in eight weeks of structured training.
• The specific group(s) driving the skeletal muscle mass increase are not differentiated in the abstract.

HIFT led to greater body fat reduction compared to RT, although both groups improved from baseline.

• Body fat reduction was greater in the HIFT group compared to the RT group.
• Both HIFT and RT showed improvement in body fat from baseline.
• HIFT consisted of four sets of 30-second exercises at 30% 1RM.
• RT involved three sets of 12 repetitions at 70% 1RM.

Both HIFT and RT groups showed increased 1RM bench press strength.

• Increases in 1RM bench press were observed in both the HIFT and RT groups.
• Physical performance was evaluated as part of the outcome measures.
• The 1RM was also used to prescribe training intensity for both groups.
• No comparison to the control group's bench press performance was specified in the abstract.

HIFT significantly increased VO2max compared to both RT and the control group, while RT improved VO2max compared to the control.

• HIFT produced greater VO2max improvements than both the RT group and the control group.
• RT also improved VO2max compared to the control, indicating a hierarchical effect of exercise intensity on cardiovascular fitness.
• VO2max was assessed as a measure of cardiovascular fitness.
• The HIFT protocol used 30-second high-intensity functional exercises at 30% 1RM across four sets.

The study compared HIFT and RT protocols matched for frequency and duration but differing in intensity and structure.

• HIFT involved four sets of 30-second exercises at 30% 1RM.
• RT involved three sets of 12 repetitions at 70% 1RM.
• Both interventions were performed three times per week for eight weeks.
• Thirty-four overweight men (mean age 31.91 ± 2.44 years, BMI 27.78 ± 1.47 kg/m²) were randomized into HIFT (n=13), RT (n=10), and control (n=11) groups.
