The Power of Combined Exercise: Revolutionary Approaches for Weight Management and Cardiometabolic Health

In the evolving landscape of exercise science, a powerful trend is emerging: strategically combining different exercise modalities produces superior benefits compared to single-approach methods. Recent research has revealed that blending exercise types—whether mixing intensity levels or combining different exercise modalities—could be a game-changer for managing chronic conditions like obesity and hypertension. .

Combined exercise refers to a structured workout regimen that integrates multiple types of exercise modalities or intensities to maximize health benefits. This can include:

• Combining different exercise types, such as resistance training, aerobic exercise, flexibility training, or breathing exercises.

• Mixing exercise intensities, such as blending high-intensity interval training (HIIT) with moderate-intensity continuous training (MICT).

• Integrating different physiological targets, such as cardiovascular endurance, muscle strength, metabolic health, and flexibility, into a single training approach.

The goal of combined exercise is to leverage the unique benefits of each modality while mitigating potential drawbacks, leading to superior outcomes for weight management, cardiometabolic health, and overall fitness.

The Growing Challenge of Chronic Conditions

Obesity and hypertension represent two of the most prevalent health challenges worldwide. According to the World Health Organization, obesity has more than quadrupled since 1975, with 18% of adolescents aged 10-19 now affected. Similarly, hypertension affects over 1.28 billion adults globally and remains a leading risk factor for cardiovascular disease.

Traditional management approaches have often fallen short, prompting researchers to investigate more effective interventions. Three groundbreaking studies have recently shed light on how combined exercise approaches might provide superior outcomes for individuals with these conditions.

Study 1: Combined HIIT and Resistance Training for Young Women with Overweight/Obesity

A randomized controlled trial examined the effects of combining high-intensity interval training (HIIT) with resistance training (RT) versus HIIT alone on body composition, cardiorespiratory fitness, and glycolipid metabolism in young women with overweight/obesity.

Study Design and Protocol

The researchers divided 40 subjects into two groups:

• Experimental group: HIIT combined with resistance training (HIIT+RT)

• Control group: HIIT alone

Both groups trained three times per week for eight weeks. Comprehensive assessments of body composition, cardiorespiratory fitness, and glycolipid levels were conducted before and after the intervention.

Impressive Results Across Multiple Parameters

After eight weeks, both groups showed significant improvements in multiple health markers:

Body Composition Improvements:

• Reduced body weight

• Decreased body mass index (BMI)

• Reduced body fat percentage

• Decreased waist circumference (WC)

• Improved waist-hip ratio (WHR)

Cardiorespiratory Fitness Enhancements:

• Increased peak oxygen uptake (VO2peak)

• Improved vital capacity (VC)

• Enhanced oxygen pulse (VO2/HR)

• Increased minute ventilation

• Reduced resting heart rate

• Improved blood oxygen saturation

• Reduced blood pressure

Metabolic Health Benefits:

• Decreased fasting blood glucose

• Reduced triglycerides

• Increased high-density lipoprotein cholesterol

However, the combined HIIT+RT group demonstrated several unique advantages:

• Significant increase in muscle mass (not observed in the HIIT-only group)

• Greater reduction in 2-hour postprandial glucose

• Superior improvements in key fitness parameters:

  • Muscle mass (2.75% greater improvement)

  • VO2peak (1.61 mL/min/kg greater improvement)

  • Vital capacity (334mL greater improvement)

  • Oxygen pulse (0.51mL/beat greater improvement)

These findings suggest that while both exercise approaches are beneficial, the combination of HIIT and resistance training offers additional advantages, particularly for muscle mass development and cardiorespiratory fitness.

Study 2: Combined Training for Adolescent Obesity Management

Another study published in Scientific Reports investigated an innovative approach to exercise for adolescent boys with obesity during a three-week hospital-based weight reduction program. The researchers compared traditional moderate-intensity continuous training (MICT) with a combined approach that integrated high-intensity interval training (HIIT) and moderate-intensity continuous training in the same workout session.

Understanding the Combined Training Protocol

The combined training approach, dubbed "COMB" by researchers, was thoughtfully structured:

• 20% of the workout consisted of high-intensity intervals (3 repetitions of 2 minutes at 95% of peak oxygen uptake)

• 80% involved moderate-intensity continuous exercise (30 minutes at 60% of peak oxygen uptake)

This strategic blend created a workout that leveraged the benefits of both high-intensity and moderate-intensity exercise while potentially mitigating the drawbacks of each approach when used in isolation.

Remarkable Results for Body Composition and Fitness

After just three weeks, the combined training group demonstrated several unique advantages compared to the MICT-only group:

Body Composition Benefits:

• While the traditional MICT group lost more total body weight (8.4 kg vs. 5.0 kg), the combined training group maintained muscle mass better

• Both groups lost similar amounts of fat mass (approximately 4.2 kg)

• The combined approach preserved basal metabolic rate more effectively

Fitness Improvements:

• Only the combined training group improved peak oxygen uptake (VO2 peak), showing about a 12% increase

• The combined group increased maximal fat oxidation rate by approximately 6%, while the MICT group showed no improvement

• Unlike the MICT group, the combined approach helped maintain lean body mass, crucial for long-term metabolic health

These findings suggest that the strategic combination of exercise intensities might accelerate positive adaptations, particularly for metabolic health markers that are critical for long-term weight management success.

Study 3: Combined Exercise for Hypertension Management

Building on the concept of combined exercise approaches, a third study examined how integrating breathing exercises with high-intensity bodyweight interval training affects adults with hypertension. This 10-week intervention involved 96 adults (average age 59.4 years, 84% female) with hypertension.

The Study Design

Participants were randomized into four distinct groups:

1. Breathing Exercise (BE) group: 30 minutes per day, 3 days per week

2. High-Intensity Bodyweight Interval Training (HIBIT) group: 60 minutes per day, 3 days per week

3. Combined Exercise (CE) group: BE 30 minutes plus HIBIT 60 minutes per day, 3 days per week

4. Non-Exercise Control (CON) group

This design allowed researchers to isolate the effects of each exercise type and determine whether their combination offered synergistic benefits.

Comprehensive Health Benefits Observed

The results revealed significant benefits across multiple health parameters:

Blood Pressure Improvements:

• While the breathing exercise group showed the greatest reduction in systolic blood pressure compared to the control group, all exercise groups demonstrated improvements

• The combined exercise approach effectively reduced both systolic and diastolic blood pressure

Cardiorespiratory Fitness Enhancement:

• The increase in 6-Minute Walking Test (6MWT) values in the combined exercise group was significantly greater compared to all other groups (p = 0.000, effect size = 0.296)

• This substantial improvement in functional capacity has important implications for daily activities and quality of life

Blood Lipid Profile Optimization:

• The combined exercise group showed significant reductions in total cholesterol, LDL, and triglyceride levels compared to the control group

• The average reduction in total cholesterol levels was 20.8 mg/dL

• LDL decreased by 20.1 mg/dL (p = 0.014)

• Triglycerides decreased by 40.4 mg/dL (p = 0.04)

These improvements in blood lipid profiles are particularly noteworthy, as they represent additional cardiovascular benefits beyond blood pressure reduction.

Connecting the Dots: The Power of Combined Exercise Approaches

When we examine these three studies together, a compelling pattern emerges: across different populations and health conditions, combined exercise approaches consistently outperform single-modality interventions. From young women with obesity to adolescent boys and older adults with hypertension, the benefits of strategically combining exercise types are remarkably consistent.

Common Benefits Across Studies:

• Superior Cardiorespiratory Fitness Improvements: All three studies showed that combined approaches led to greater enhancements in oxygen uptake, vital capacity, or functional capacity.

• Better Body Composition Outcomes: Combined approaches consistently demonstrated advantages for preserving or increasing muscle mass while reducing fat mass.

• Enhanced Metabolic Health: From improved lipid profiles to better glucose regulation, combined approaches showed advantages for metabolic health markers.

• Comprehensive Health Benefits: Rather than targeting a single aspect of health, combined approaches improved multiple health parameters simultaneously.

The Science Behind Combined Exercise Success

Why do these combined approaches work so well? Several potential mechanisms may explain their effectiveness:

Complementary Physiological Adaptations

Different exercise modalities trigger distinct physiological responses and adaptations:

• Resistance Training: Primarily stimulates muscle protein synthesis, enhances muscular strength and endurance, and improves glucose metabolism through increased GLUT4 translocation.

• High-Intensity Interval Training: Enhances cardiovascular function, mitochondrial biogenesis, and metabolic flexibility.

• Moderate-Intensity Continuous Training: Improves vascular function, fat oxidation capacity, and cardiac efficiency.

• Breathing Exercises: Enhance autonomic nervous system function, reduce sympathetic activation, and improve respiratory muscle strength.

When combined strategically, these modalities can create complementary effects that address multiple aspects of health simultaneously.

Optimized Hormonal Responses

Combined exercise approaches may create more favorable hormonal environments:

• Growth Hormone and Testosterone: Resistance training components stimulate these anabolic hormones, supporting muscle preservation and development.

• Catecholamines: High-intensity components increase catecholamine release, enhancing fat mobilization and energy expenditure.

• Cortisol Regulation: Breathing exercises may help regulate cortisol levels, potentially mitigating some of the stress responses associated with high-intensity exercise.

Enhanced Molecular Signaling

At the cellular level, different exercise modalities activate distinct but overlapping molecular pathways:

• AMPK Activation: Primarily stimulated by endurance exercise, this pathway improves mitochondrial function and fat oxidation.

• mTOR Signaling: Activated by resistance exercise, this pathway promotes protein synthesis and muscle growth.

• PGC-1α Expression: Stimulated by both resistance and endurance exercise, this co-activator enhances mitochondrial biogenesis and metabolic adaptations.

Combined approaches may optimize the activation of these pathways, potentially leading to more comprehensive adaptations than single-modality exercise.
