Exercise machines are common within commercial gyms and may allow the general population to receive an adequate training stimulus to benefit their health if performed regularly. However, it should be noted that machine-based exercises, particularly those that use single-joint muscle actions, may not provide an optimal strength-power training stimulus since the muscle groups involved in athletic movements are not typically used in an isolated manner (5, 81). This in turn may reduce the task specificity of isolation exercises and reduce the transfer of training to athletic performance (2, 7, 70, 81). While single-joint isolation exercises may improve an athlete’s strength, this alteration may not transfer to athletic performance due to a lack of coordinative patterns between muscle groups (81). For example, Nordic hamstring curls provide a great eccentric strength training stimulus (22); however, the stiff-legged deadlift may serve as a more advantageous exercise due to the incorporation of both the knee and hip joints as well as the stabilization of the shoulder joints and back. Furthermore, the stiff-legged deadlift serves as an assistance exercise to other movements such as weightlifting derivatives (i.e., variations of a traditional snatch or clean and jerk movement altered by modifying the starting position, the depth of the catch position, or the omission of the catch phase).
Introduction to Function
Published in James Crossley, Functional Exercise and Rehabilitation, 2021
Exercise machines designed to stress specific muscles and physiological systems are removed from the context in which those muscles or systems are designed to work. We can develop arm muscles, but what does the dumbbell curl really teach us about how to bend and lift a child out of a cot? The emphasis on physiological adaptation means conventional exercise is designed without any specific purpose in mind, and therefore fails to resemble any task or activity useful or relevant to daily life.
The Arab region
Published in Joe Piggin, Louise Mansfield, Mike Weed, Routledge Handbook of Physical Activity Policy and Practice, 2018
Aspire Academy and Aspetar are part of Aspire Zone, which is the country’s centre of sport excellence. It is also the heart of Doha city and representing the sporting ambition of Qatar in terms of prestige, design, and architecture. When the weather is cooler it is the place to be for casual sport (e.g. five-a-side football and jogging) and for family picnics. Outdoor exercise machines are also available for the general public to use as well as cycling paths. Teachers and administrators are encouraged to implement the four QAS components, which are: healthy heart, healthy bones, healthy muscle, and healthy person. The goal is to achieve the 60 minutes requirement of physical activity per day. It is expected that by 2020, the physical activity of children in Qatar will increase by 20 per cent, and QAS will be integrated into 50 per cent of schools in Qatar.

Cardiorespiratory fitness and muscular strength testing are assessed at baseline (Body & Cancer commencement) and after six weeks. Muscular strength is ascertained using the 1 repetition maximum test (1RM) [18] in all six resistance exercise machines (Technogym (Gambettola, Italy)). Cardiorespiratory fitness (VO2-peak) is estimated by the use of a Watt-max test (stepwise work capacity) [19,20] on a stationary exercise cycle (Monark Ergomedic 839E, Sweden). Prior to testing, participants work at a steady state level for approximately 5 min. Hereafter, the Watt-max test commences at 47–87 Watt, increasing by 10–20 Watt with each consecutive minute until volitional fatigue. VO2-peak is then estimated using the formula VO2-peak = 0.16+ (0.0117 × maximal power output), where maximal power out is measured in watts. Test protocols used at baseline (e.g., 67 W, increasing 15 W/min) are used again at six weeks for comparability. In addition, patient-reported outcomes, including self-reported physical activity levels using a modified version of the Saltin-Grimby Physical Activity Level Scale [21] are obtained. Demographic, patient-reported outcomes, and objective physiological outcomes, as well as attendance, are prospectively recorded in a Body & Cancer database.

At baseline and annually from 3 to 8 years, participants completed the WHI Physical Activity Questionnaire21 on their usual everyday physical activity. Measures encompassed exercise and walking, including their frequency and duration.22 Following previous research,3,4,23,24 we created two binary measures, which indexed no exercise and no walking. Exercise was defined as moderate (e.g., aerobics or jogging) or strenuous (e.g., using an exercise machine, such as a stationary bicycle or a treadmill, or calisthenics) exercise at least once each week, excluding walking. “No exercise” was given a score of 1 and “any exercise” was given a score of 0. Walking was defined as average, fairly fast, or very fast walking outside the home for more than 10 minutes without stopping at least once each month. “No walking” was given a score of 1 and “any walking” was given a score of 0.
Designing and usability testing of a new prototype active footrest for knee extension exercise among office workers

The data from the usability test showed that the mean SUS score for the active footrest prototype was 89, which indicated its desirable usability. Moreover, the office workers who used the footrest reported no practical problem with it. However, the usability of this device after production should be evaluated in long-term use to determine its effectiveness and the duration of its use per day. Barbieri et al. [24] developed and fabricated sit–stand desks with semi-automated position changes. This workstation was assessed by nine office workers. The results showed that the acceptance rate of this intervention increased from 72% in the first week to 82% in the eighth week. Carr et al. [56] also examined the usability of a pedal exercise machine to reduce sedentary behavior during work with the participation of 18 office workers (two males and 16 females). The results of this study, in line with the present study, confirmed the usability of this active workstation in the office workstation.
