Brief Summary

Overweight and obesity is becoming increasingly prevalent, constituting 64% of all adults in England, causing an incessant rise in cost to the National Health Service. Exercise and physical activity have the potential to reduce incidence of overweight and obesity, as well as improve obesity-related ill health. However, overweight and obese individuals are inherently sedentary and do not meet exercise guidelines. Same-session concurrent exercise training may be the most efficient exercise strategy to incorporate both cardiovascular- and strength-based exercise, both of which are vital for health-related benefits. This research project will aim to determine the feasibility of completing an 8-week concurrent exercise training programme in overweight and obese sedentary males. This study will aim to recruit adult males with a BMI above 25 kg.m2, who are otherwise healthy, but not regularly achieving exercise guidelines (less than 150 minutes of physical activity and 2 strength training sessions per week). Participants will undergo baseline and post-training testing of cardiorespiratory fitness, strength, heart and metabolic health, as well as a series of questionnaires and a semi-structured interview. They will then be randomised into one of two groups (high-intensity interval training or concurrent training) to complete twice-weekly exercise sessions for 8 weeks. The aims of this study are to evaluate the feasibility of performing 8-weeks of either concurrent, resistance or high-intensity interval training in overweight and obese males. This will be determined through assessment of cardiorespiratory fitness, strength, heart health, metabolic health, enjoyment, adherence and attendance.

Outcome Measures

Primary Outcomes (5)

• Adherence

  Feasibility of the study will be measured via adherence to the exercise programme (number of intervals of HIIT or repetitions of resistance exercises completed).

  Throughout intervention (8 weeks)

• Attendance

  Number of exercise training sessions attended.

  Throughout Intervention (8 weeks)

• Enjoyment

  Scores will be taken from the Physical Activity Enjoyment Scale (PACES), which will be completed at the end of each exercise session.

  Throughout intervention (8 weeks)

• In-Session Heart Rate

  The heart rate (in beats per minute) at the end of each HIIT interval or set of resistance exercise measured via Polar Wristwatch.

  Throughout intervention (8 weeks)

• Ratings of Perceived Exertion

  The Rating of Perceived Exertion (RPE) at the end of each HIIT interval or resistance exercise, provided by each participant on the Borg category-ratio 100 scale, expressed in arbitrary units.

  Throughout intervention (8 weeks)

Study Arms (2)

High-Intensity Interval Training Group

EXPERIMENTAL

Participants in the High-Intensity Interval Training (HIIT) group will complete 8 weeks of twice-weekly HIIT of 30 minutes in duration. Heart rate, ratings of perceived exertion, affect and enjoyment will be assessed. This will include a five minute warm-up on a cycle ergometer, followed by 10 x 60 second repetitions on the cycle ergometer interspersed with 60 seconds rest. A five minute cooldown will follow on the cycle ergometer.

Other: Exercise Training

Concurrent Training Group

EXPERIMENTAL

Participants in the Concurrent Training (CT) group will complete 8 weeks of twice-weekly CT of 30 minutes in duration. Heart rate, ratings of perceived exertion, affect and enjoyment will be assessed. This will include a five minute warm-up on a cycle ergometer, followed by two sets of four then eight repetitions of deadlift, squat, bench press and shoulder press resistance exercises. Thereafter, 5 x 60 second HIIT cycling intervals will be completed on a cycle ergometer, after which a five minute cooldown will ensue.

Other: Exercise Training

Interventions

Exercise Training OTHER

Either of; 8-weeks twice-weekly High-Intensity Interval Training or Same-Session Concurrent Exercise Training.
