Normative maximal oxygen uptake values are provided in Table 6.2.2. Average oxygen uptake during men’s singles match play ranges between 26 and 33 ml.kg.min−1 (58%–74% V̇O2max) (Zagatto et al., 2016). Aerobic capacity can be determined on a treadmill according to guidelines outlined in Chapter 11.3, which increases both speed and gradient. To better simulate sporting demands, a table tennis–specific graded exercise test may be used if required equipment is available (Zagatto et al., 2016). Athletes perform only forehand offensive strokes against a ball throwing machine used as an ergometer. Ball speed (~35 km.h−1) and lateral ball oscillation are kept constant. The machine alternately shoots balls to two points on the table (30–40 cm either side of the table centre line, so that the ball contacts the table 50–60 cm from the net) simulating an opponent’s shot. The frequency of ball deliveries by the machine (ball/min) determines exercise intensity. Typically, initial intensity is 30 balls.min−1 with increments of 3–4 balls. min−1 every 2 min until volitional exhaustion.
Mechanics of Cycling

A treadmill is a useful device, especially when used inside a wind tunnel, as the conditions are then most near real cycling and actual bicycles may then be used. Treadmills may be inclined to give a drag force.26 Friction rollers are of limited use as the load is not quantified, nor is air drag simulated. However, they do require that the rider balance as during normal cycling.

Water-based exercise sessions can be individual or group sessions with exercise delivered by a health professional to a number of individuals and performed in unison, or circuit classes involving a number of exercise stations performed one after each other. The latter is most suitable if equipment with limited supply (e.g. hydro-bikes or hydro-treadmills) are available.
Effect of treadmill walking for anxiety, depression, and social well-being in women with diabetes type 2: A randomized controlled trial

There is data confirming that physical activities and exercises are a cost-effective treatment for poor mental health with limited negative side-effects and are beneficial for women with DT2 (Biddle & Mutrie, 2008; Maharaj & Nuhu, 2015). However a systematic review shows conflicting effects of exercise training on psychological outcomes or how depression and anxiety are impacted by exercise training for DT2 (Sukala et al., 2013; Van der Heijden et al., 2013). Treadmill exercises are aerobic in nature and are used for physiological and psychological benefits. However there are limited studies and specifically less emphasis and data investigating treadmill exercises, psychological health and psychological well-being outcomes for women presenting with DT2 (Kull, 2002). There is therefore a need to determine an easy and safe exercise program for women with DT2 for outcomes of psychosocial well-being which can be prescribed by health professionals as a beneficial intervention for this population. Based on this we designed this study to investigate the response of moderate intensity treadmill walking for anxiety, depression and social well-being for women with DT2.
Comparison of the effects of aerobic training alone versus aerobic training combined with clinical Pilates exercises on the functional and psychosocial status of patients with ankylosing spondylitis: A randomized controlled trial
Published in Physiotherapy Theory and Practice, 2023
All patients were given training for aerobic exercises by the physiotherapist for 3 days a week during the 8-week period. The patients performed warm-up (5 minutes) and cooldown (5 minutes) exercises, respectively, before and after walking on the treadmill. The intensity of the aerobic exercise phase was 40%–50% for 0–2 weeks, 50%–60% for 2–4 weeks, and 60%–75% for 4–6 weeks, and the duration of the aerobic exercises was 20 minutes. During the last 2 weeks, the intensity of the aerobic exercise was 60%–75%, and the duration was increased to 30 minutes. Heart rate was monitored using a Polar heart rate monitor placed on the patient. The target heart rate of each patient was calculated by using the Karvonen formula (Target heart rate = (220 – age – resting heart rate) × desired exercise intensity + resting heart rate).

The current study was performed on a treadmill, while most clinical tuning studies are performed in a conventional overground gait lab [12,15]. The advantage of treadmill walking is that it enables investigators to impose a constant walking velocity between conditions and data analysis could be performed on many continuous strides. Therefore, we were able to investigate the results of tuning without confounding effects of walking velocity between conditions. On the downside, this fixed velocity may complicate translation of our effects to daily life overground walking, since AFOs influence walking speed [36]. Another aspect of treadmill walking is that there are potential differences to overground walking [37–40]. To investigate whether and how treadmill walking may influence the effect of AFO-FC tuning, a pilot study was conducted before implementation of the protocol in clinical routine. This pilot study, comparing the effects of AFO-FC tuning on a treadmill to overground walking, confirmed similar tuning effects between overground and treadmill walking, when investigating the currently used protocol in healthy adults. However, some consistent differences were found, highlighting the importance of using treadmill-specific reference data for outcome parameters, especially for joint kinetics. Results of this pilot study can be found in the Supplementary material.
